Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in the following chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here.

IMPORTANT SENSITIVITY ADJUSTMENT PROCEDURE! To fully achieve the Mackie 8•Bus console’s impressive headroom and specs, you should “tune” channel sensitivity for each channel. FOLLOW THIS PROCEDURE FOR EACH CHANNEL IN USE: 1. Assign signal to channel fader: ■ If channel will be used with a micro– phone, MIC/LINE switch should be up & FLIP switch should be up. ■ If channel will be used with line input, MIC/LINE switch should be down & FLIP switch should be up. ■ If channel will be used with a tape input keep the FLIP switch down. 2. Set channel strip controls as follows: ■ TRIM pot all the way counterclockwise (+4dB) ■ AUX SEND controls all the way counterclockwise (off) ■ EQ switch up ■ LOW-CUT switch either on or off (on recommended for mic inputs) ■ Pan hard left or right ■ Channel fader at UNITY ■ SOLO switch down 3. ■ Make appropriate “noise” into the channel input. For example, have a performer play/ sing/strike something or someone, etc., at the level at which they’re going to record or perform. Don’t just play a single sustained note, but rather, jam away as you would be during recording or performance. If the channel is being used for a tape input during mixdown, roll an already-recorded track from your recorder. 4. The channel’s –20dB LED may light. The L/R main meters will show the actual internal operating level of soloed signals. Now you will optimize levels. 5. ■ For mic or line inputs, adjust the TRIM control clockwise to get peaks that regularly hit 0dB on the L/R meters. For mic inputs this may require full CW rotation depending on the sensitivity of the mic. 6. If desired (optional): ■ Press the EQ switch in. ■ Adjust the channel strip’s EQ to about what you will be using during the session. ■ Re-perform Step 5. 7. ■ Return the channel strip’s SOLO button to its up position. 8. ■ Repeat Steps 1-7 on the next channel that is being used. Please put your serial number here for future reference (i.e., insurance claims, tech support, return authorization, gloating privileges, etc.): Serial # PLEASE! SAVE THE SHIPPING BOX! Yes, we know it’s only slightly smaller than a doublewide mobile home, but you will need the entire carton and internal foam if your console ever needs service at some time in the future. If your kids make the box into a fort and cut holes in it — or if you stuff it in the dumpster of the fast-food place next door to your studio, we may have to sell and ship you another packing box later on. Don’t end up buying an empty box! 1 24•8 32•8 Owner’s Manual Version Rev.

As a matter of policy, our Manual Table of Contents always skip things that are on the facing page to the actual listing. Seems like we’re stating the obvious to tell you that the Introduction is next to your right hand. SECTION 1: Introduction The Mackie 8•Bus Series is a flexible ‘in-line monitoring’ style console. They are available with 24 or 32 microphone/line inputs fed into 8 submix buses, 2 stereo mix buses and 6 auxiliary send buses. There are 24 or 32 tape return inputs for multitrack monitoring and mixing or for use as additional line inputs. The 8•Bus Series is designed to be the mixing and communications hub in a multitrack recording studio and is also an excellent choice for sound reinforcement work. Numerous inputs, flexible sends and terrific EQ combined with the legendary Mackie headroom and noise floor specs make your work easy. It’s clean. It’s quiet. It’s packed with features. It’s affordable… So pat yourself on the back! You’re doing something sensible here! PANEL LAYOUT AND FUNCTION LAYOUT AND FUNCTION GENERAL INFORMATION GENERAL INFO RECORDING RECORDING PA AND SOUND REINFORCEMENT PA & SR APPENDICES ADD-ONS SPECS ETC. IF YOU IGNORE MANUALS... You’ll probably ignore this one, too. That’s OK, the crack Mackie Documentation Department will get to go on their annual “Typing Without Walls” outing at campsite four in the Woodinville RV Park anyway. But this is a really great manual! It’s got Where It Is and What It Does and How To Use It covered totally, with pictures and diagrams and absolutely no pop quizzes. Do yourself a favor and at least check out Section 2 and the block diagram for starters. The 8•Bus Series has a number of routing tricks that could be hard to suss out without a guide. Then, if that’s all you can take without pumping some sound through the console, put the manual in the bathroom for future reference or read it while you eat your lunch. If you’re even more terminally impatient, try to look for these two icons: They cover information that is absolutely critical or is unique to the 8•Bus Series. At some point, it’s still a good idea to browse through the rest of the manual. In addition, sections marked with the A CLOSER LOOK icon include in-depth information… or at least our own opinions. (CONNECTIONS, ADD-ONS, SPECIFICATIONS, ETC.) SERVICE SERVICE MASTER TRACK SHEETS FOR DUPLICATION TRACK SHEETS BLOCK DIAGRAM BLOCK DIAGRAM 3 EQ IN 75 Hz 18dB/oct LOW CUT PAN L R SECTION 2: Panel Layout and Function OVERVIEW INPUT CHANNELS (CHANNEL STRIPS) The panel layout of the Mackie 8•Bus Series follows the traditional arrangement: input channel strips to the left, with a master output/ monitoring/cue section to the right. Additionally, most of the Mackie input/output jack panel is located at the top of the mixing panel, for easy accessibility and patching. The tape outputs and inputs are on the rear panel. The 24 or 32 input channel strips on the Mackie 8•Bus consoles are identical, and contain all of the level, assignment and equalization controls for each input channel. This section describes the controls and functions of each feature of an input channel in detail. U LEVEL OO +15 HI/LO EQ TO MIX-B MIX-B MONITOR SPLIT EQ FLIP SW CHANNEL SOURCE OL -20 PAN The channel fader (1) is 100 millimeters long, with a precise logarithmic taper and attenuation in dBs printed along the slot for exact and repeatable level adjustments. The fader affects either the mic or line input to the channel (for recording) or the tape return to the channel (for mixing), depending on the position of the FLIP switch. SOLO MUTE 24 dB 10 5 MUTE 1-2 U The MUTE switch, located at the top of the fader (2), turns off the primary outputs of the channel: the eight buses, the L & R buses, the channel solo, the direct output and the postfader AUX sends. Pre-fader aux sends are not muted. With the exception of lighting the mute LED, pushing the MUTE switch is the same as pulling the fader all the way down. 3-4 5 5-6 10 7-8 20 30 FADER L/R MIX 40 GOURMET PAN CONTROL AND ASSIGNMENT SWITCHES 50 60 CHANNEL INPUT/OUTPUT OO MASTER I/O CHANNEL STRIPS MASTER SECTION CHANNEL INPUT/OUTPUT MASTER I/O CHANNEL STRIPS MASTER SECTION 4 The PAN control (3), immediately above the fader, pans the channel signal between the two sides of the L/R Mix buses, and also between odd and even pairs of buses 1 through 8. The actual bus assignment of the PAN control depends on the positions of the five assignment switches located along the length of the fader. With no switches depressed, the PAN control has no effect (well, unless you solo the channel; it still pans the solo). Pushing the L/R MIX switch (4) assigns the PAN to the main L/R Mix buses. Panning from L to R moves the sound smoothly (with constant loudness) from the left channel to the right channel. Assigning the PAN to a pair of the 8 buses has a similar effect. For example, pushing the 1-2 switch assigns the PAN to buses 1 and 2, and panning L to R will move the sound from bus 1 to bus 2 (from odd to even). If you want to equally assign a channel to both buses 1 and 2, leave the PAN control at the top, or center, of its travel. If you only want bus 2, turn the PAN control fully clockwise (to the right). Other comparably-priced consoles provide as little as 50dB attenuation/separation. We use active, buffered circuitry and a custom-taper potentiometer –20 AND OL LEDs • Turn down the channel. If this doesn’t fix it, your input signal is too hot (gasp). Use an external pad to reduce the level (see the sidebar on page 24). CHANNEL SOLO The channel SOLO switch (6) assigns the output of the channel PAN control to the stereo solo buses and disconnects all other sources from the monitor section. SOLO does not interrupt the eight Submasters, the L/R Mix or the AUX sends, and can be used at any time without affecting the recording process. SOLO is handy for spot-checking the presence and quality of individual inputs while setting up, recording and mixing. More than one SOLO switch may be pressed at the same time, allowing you to listen to the blend of any combination of channels throughout the console in stereo. PHANTOM POWER CHANNEL MIC/LINE LINE IN BALUNBAL DIRECT OUT INSERT TIP = OUT RING = IN CHANNEL C GAIN MI–10 dBV S SITIVITY EN The two LEDs (5) next to the PAN control check the channel strip signal level at three important circuit points: at the output of the mic/line preamp, after the EQ and after the channel fader amplifier. The green LED marked –20 is there to assure you that, yes, something is plugged into the channel (and yes, it does have some output). Most signals more interesting than tape noise will cause the green LEDs to flicker, so they give you a good visual indication of which channels are active. Any peaks higher than –20dBu (@ 1kHz) trigger the indicator. When we say “channel”, we mean the signal going through the channel fader… but not the signal going through the MIX B Section. Please refer to the MIX B section of this manual, starting on the next page, for more details. The red LED, labeled OL for overload, lights when the signal level is high enough to cause clipping at any of the three test points. In normal operation it will almost never light. If it is flashing at you, your level in that channel is much too high. You need to turn something down. • First try the mic/line trim. If that has no effect, • Turn down the EQ and/or the insert device, and if that doesn’t fix it, On the Mackie 8•Bus console, the SOLO assignments are stereo except for the AUX sends. SOLO maintains the perspective set up with the PAN controls. When any SOLO button on the console is depressed, its associated SOLO LED will glow steadily, and the RUDE SOLO LITE above the 24 8•Bus LED meters blinks annoyingly, serving as a reminder with an attitude. The channel SOLO function is normally postfader/post-mute, but can be modified for PFL or Pre-Fade (and pre-mute) Listen. See Appendix B: Options, Add-Ons, and Extra Stuff. Note: All the SOLO buttons on the 8•Bus Series operate in the same way (although they’re not all stereo like the channel SOLO). SOLO does not interrupt recording; it only affects the control room monitor. HIGHLY, MEGA-MONDOIMPORTANT: SOLO is 24 intended for more than just “soloing.” It is THE way to set levels for best noise and headTRIM room. Complete instructions on proper level setting using SOLO are in Section 3: General Information, starting on page 19. LIN E to achieve 87dB attenuation. You get far better channel separation plus freedom from level shifts caused by channel assignment and panning. In addition, our pan pots are constant loudness. When you sit between a pair of monitors and pan from side to side, the apparent volume at your ears should stay the same, no matter where the signal is positioned. Our special pan circuitry maintains consistent apparent energy whether the pot is dead center, hard left or hard right. +4 10dB -40dBV MIC/LINE 50dB TAPE GAIN FLIP U PHANTOM POWER HI MID –15 CAUTION: After switching PHANTOM Power on or off, wait 1 minute before changing any mic/line switch settings in that 8-channel block. At the top of every eight channels is a PHANTOM Power switch (7). Pressing it sends +48VDC to the eight XLR sockets to the switch’s left. For instance, depressing the PHANTOM switch above Channel 8 sends phantom power to the XLRs on channels 1 through 8. NOTE: It is always a good idea to check with the Mic manufacturer to verify phantom power requirements. +15 3k 1k 5k FREQ 500 18k NORMAL 2 BAND WIDTH OCTAVES 1 12 3 U LO MID –15 +15 250 220 350 FREQ 45 3k U HI 12k TRIM –15 +15 U The TRIM control (8) sets the gain of the input amplifier for the MIC and LINE inputs. Proper setting of the TRIM control is essential for good noise and headroom performance. Trim pot settings may vary widely depending upon the input level. The output of different keyboards, drum machines, guitar effects boxes, etc., vary from extremely weak to so hot that they can practically be connected directly to speakers.

Sorry, but logically the input to the channel is the next thing to talk about. That’s because it’s the source of the signal applied to the channel fader and PAN control. 5 SOURCE OL -20 PAN SOLO The MIC/LINE switch (9) is located way up amongst the channel jacks. It selects whether the MIC jack (pin 2=hot[+], pin 3=cold[–], pin 1=shield) or the LINE jack (balanced 1/4" phone… tip=hot, ring=cold, sleeve=shield) is connected to the input amplifier.

As the label indicates, the MIC/LINE input (after Mic/Line preamp) is fed to the channel fader when the FLIP switch is in the up position. This is the normal mode for tracking and overdubbing. In the down position, the TAPE return (the output signal from the corresponding track of your recorder) is fed to the channel fader. This is the normal position for mixdown. To recap - when the FLIP is up, the Mic/Line feeds channel and Tape return feeds MIX-B. When the FLIP is down, the channel is Tape and MIX-B is MIC/LINE. FLIP... FLOP. OK? For live PA, leave the FLIP switch up. MIX-B / MONITOR R U OO THE FLIP SWITCH: MIC/LINE OR TAPE L/R MIX Each channel strip has a dual signal path (Enter MixB!) with extremely flexible switching. This allows either the mic/line inputs or tape return inputs to be routed through either the channel fader path or Mix-B with separate EQ and monitoring. Both of the signal paths can be combined into the main mix by depressing the Mix-B to L/R Switch in the master section. OK, now we jump down the channel again to the MIX-B/Monitor section. This handy and very simple feature is also called “in-line monitoring” and is found on quite a few consoles. So we’re not claiming that it’s anything new… we just added some extra features for more flexibility. MIX-B/Monitor routing options can get a bit complicated, so pay attention. Also, we did add something that other in-line monitoring systems don’t have. So double pay attention. The MIX-B buses are a stereo pair, independent of the 8-plus-2 recording buses we’ve talked about so far. There are three sources available to MIX-B: MIC/LINE or TAPE (via the FLIP switch) and the pre-fader output of the channel strip (via the SOURCE switch). A fourth source, post-fader output of the channel 6 strip (via the source switch), can be achieved by modifying the channels. Instructions for this modification can be found on our website at www.mackie.com (click on Support). Or you can call Tech Support at 1-800-258-6883 for assistance. 1. When the Mix-B SOURCE switch (11) is up, MIX-B receives its input from the FLIP switch. Remember, the FLIP switch alternates MIC/LINE or TAPE to the channel strip and to MIX-B. With TAPE as an input (SOURCE up to select the FLIP switch, and FLIP in the up position), the MIX-B section functions as a tape monitor submix, allowing you to listen to the inputs and outputs of your multi-track recorder as you record. This is the most common use of the MIX-B section, during tracking and overdubbing. 2. With MIC/LINE as an input (SOURCE up to select the FLIP switch, and FLIP in the down position), MIX-B becomes an additional input to add tracks or effects during a mixdown. Simply plug the additional signal into the MIC or LINE connector. Although they are normally separate, a button (MIX-B TO L/R MIX) in the Output Panel (see below) can add the output of the MIX-B buses to the L/R Mix buses. Voilà! Double your mix inputs! 3. With CHANNEL as an input (SOURCE down in CHANNEL position), MIX-B taps its signal from the channel strip, just before the channel fader. MIX-B is separately pan-able, EQ-able and can be used as an alternative stereo mix, a stereo auxiliary send, a “mix-minus” bus, a quadraphonic or surround feed, you name it. Mix B can also have its own aux send (see Aux sends 3-6). Check out Section 3: General Info and the Block Diagram for more information on MIX-B routing. MIX-B PAN The PAN control (12) routes the channel’s MIX-B signal across the left and right MIX-B buses. MIX-B LEVEL The LEVEL control (13) sets the level of the channel sent to the MIX-B buses. The gain structure of this circuit (like the AUX send 1–6 circuits, below) includes extra amplification. What this means to you is that you will always have plenty of gonadotropic gain available for the MIX-B buses. Full left on the LEVEL control is off; the midpoint of travel is “U”, or unity gain; full right is 15dB of boost. MIX-B SPLIT The SPLIT switch (14) in the MIX-B section splits the EQ section of the channel when depressed. In the up position, all four sections of EQ remain, if engaged, in the primary channel signal path feeding the channel fader and the 8-plus-2 buses. In this mode there is no equalization in the MIX-B path. When the SPLIT switch is depressed, the HI and LO shelving sections of the EQ are removed from the channel signal and inserted into the MIX-B signal path. The HI-MID and LO-MID parametric sections of the EQ remain, if engaged, in the channel signal path. The SPLIT function allows you to EQ the channel’s signal and its MIXB signal separately. Note: When the EQ is split, the main EQ IN/OUT switch only switches the channel signal’s parametric sections. It does not affect the shelving sections split to MIX-B. EQ SECTION Each 8•Bus channel strip equalizer section has four bands (HI MID, LO MID, LO, and HI) plus a low-cut filter. The equalizer can be split between main channel signal and MIX-B signal. +15 +10 +5 0 –5 –10 –15 20Hz 100Hz 1kHz Freq. center: 1k; Bandwidth: 1/12-octave; ±15dB boost/cut 10kHz 20kHz +15 +10 +5 0 –5 –10 –15 20Hz 100Hz 1kHz 10kHz 20kHz Freq. center: 1k; Bandwidth: 1-octave; ±15dB boost/cut +15 +10 +5 0 –5 –10 –15 20Hz 100Hz 1kHz 10kHz 20kHz Freq. center: 1k; Bandwidth: 3-octave; ±15dB boost/cut +15 +10 +5 0 –5 –10 –15 20Hz HI MID EQ The HI MID EQ section (15) is a +15 true 3-control parametric design, +10 offering: A) bandwidth variable +5 from 3 octaves to 1/12 octave (16); B) ± 15dB of equalization (17) and; 0 C) variable frequency center from –5 –10 500Hz to 18kHz (18). We spent a lot of time on this –15 20 part of the 8•Bus Series’ EQ. One of the things we’ve always noticed about lower-priced consoles was +15 how “drastic” their Hi Mid EQ +10 sounded. Even a little boost could +5 induce honkiness and nasality. 0 Frankly, Hi Mid EQ on many –5 boards is not that useful in studio –10 applications for just this reason. Hz 100Hz 1kHz 10kHz 20kHz Freq.: 500Hz-18kHz sweep; Bandwidth: 1/12-octave; ±15dB boost/cut 100Hz 1kHz 10kHz 20kHz Freq.: 500Hz-18kHz sweep; Bandwidth: 1-octave; ±15dB boost/cut When you put these consoles on the test bench, you see that the bandwidth of their EQ is simply too narrow — often around one octave. This is OK for extreme adjustments in live situations, but that’s about it. It’s just not wide enough to gently alter the multiple octaves that voices and instruments span. This is just the opposite of “classic” big-studio consoles. Their EQ (including Hi Mid) can be adjusted to be extremely broad — three or more octaves wide in many cases. When you apply this wideband EQ, it sounds far more “sweet” and “natural.” Changes sound so gradual and smooth that you can add considerably more EQ than would ever be possible with narrower-band consoles, yet without compromising the overall sound. On the other hand, ultra-narrow-band EQ also has its place, both as a corrective tool and for special effects. So why not give you even tighter control than would be possible with a 1/3octave graphic equalizer? Thus was born the 8•Bus’ 1/12-octave to 3-octave width range. At this point, as we played around with the Bandwidth and Boost/Cut controls using actual music, we realized that to limit this circuit to just Hi Mid (typically above 2.5kHz) would actually limit its usefulness. The flexibility that true parametric control provides is nice to have in the octaves below the Hi Mid region as well. So we came up with what is probably the first console Hi Mid control that can be swept all the way down to 500Hz. If Hi Mid doesn’t do it for you as a name, think of these three controls as the RovingParametric-Problem-Solver-O-Matic.

It’s time to start experimenting with it yourself. Don’t forget to try the control at its bandwidth extremes — especially at the 3-octave end. You’ll be pleasantly surprised. Conversely, if you hate technology and yearn for the sound of that old board you sold to buy an 8•Bus, you can achieve a semiparametric sound by leaving the BANDWIDTH knob in the middle at 2 octaves.

Verrry eenteresteeng, no? The LO CUT switch (23) inserts an 18dB/octave low-cut (high-pass) filter with a –3dB point of 75Hz into the main channel signal. The LO CUT filter is unaffected by the EQ IN switch. A low-cut filter is handy to get rid of room rumble, traffic noise, wind noise, popping, and other unwanted very-low-frequency sounds. It can also be combined with LO EQ boosts to produce some interesting bass curves as shown in the last EQ graph on this page. It is highly recommended that this switch be engaged for vocal microphones, especially in a live P. A. situation. AUX SENDS Auxiliary sends are generally used to provide mixes for headphone cueing and for effects sends, and in Sound Reinforcement use, can be assigned monitor submix duties. The 8•Bus Series consoles provide 6 mono auxiliary sends with several routing options. Note: All of the 8•Bus Series AUX sends have a very wide range of gain (just like the MIX-B Level control discussed earlier). The first half of the control’s rotation reaches from the off position to unity gain (U). This half of the control’s range corresponds to the full range of a conventional mixer. The second half of the control’s rotation provides you with even more gain, from unity to +15dB. AUX 1 & 2 Auxiliary sends 1 & 2 (24) have two independent level controls and share a common PRE/POST switch. When in the normal post mode, sends 1 & 2 get their signal after the channel fader and the MUTE switch. This is the usual configuration for an effects send, since the level of the effect should follow the volume adjustments made by the channel fader. L AUX 3, 4, 5, 6 TIVITY For example, when you want a super “wet” sound(mostly reverb), the extra gain allows you to bring the channel fader part way down (and the AUX send way up) so the sound is mostly reverb with just a touch of “dry” signal. Don’t worry about having mono effects sends: almost all effects units, mono or stereo, have mono inputs. Even if there are two jacks labeled Left and Right, they are almost always combined into mono internally. In the rare cases when an effect actually has true stereo inputs, it is often more convenient to ignore that and treat it as mono anyway. If you really need to send in stereo, just use two AUX sends from the console. Route AUX 1, for example, to the left input and AUX 2 to the right. Then adjust the stereo perspective by favoring one or the other send. For instance, if you have a stereo synth into channels 23 and 24, use AUX 1 on channel 23 and AUX 2 on channel 24. Note: In PRE mode, all AUX SENDS are connected pre-fader but post-EQ. This is usually the most useful setup, but if you prefer, all AUX SENDS can be modified to be pre-EQ, pre-fader. Instructions for this modification can be found on our website at www.mackie.com (click on Support). Or you can call Tech Support at 1-800-258-6883 for assistance. +4 10dB Auxiliary sends 3, 4, 5, and 6 (26) are very similar to sends 1 & 2. The differences are in the SHIFT and SOURCE switches. Read on. -40dBV MIC/LINE 50dB TAPE TRIM GAIN FLIP U 1 +15 OO SHIFT 2 The SHIFT button (27) connects the two level controls, as a pair, to either sends 3 & 4 (in the up position) or to sends 5 & 6 (in the down position). Twice the sends in half the space. SOURCE U +15 OO AUX PRE 3 U 5 +15 OO 4 U 6 OO +15 AUX SHIFT The SOURCE switch (28) breaks AUX Sends 3-6 away from the main channel strip world that sends 1 & 2 are stuck in, and allows the sends to tap from another source: the MIX-B signal for that channel. This is a very handy thing, whatever you happen to be using MIX-B for. If MIX-B is an additional input for your mixdown, then (when the SOURCE switch is depressed) AUX Sends 3-6 are effects sends connected to that source. If MIX-B is your studio monitor submix from the recorder, then AUX Sends 3-6 are a great source of headphone cue signals. They will follow playback, record and punch-ins automatically as your recorder does its stuff. PRE (3-6) The PRE switch (29) for Sends 3-4-5-6 functions just like the PRE switch sends 1 & 2, when the AUX SOURCE switch is in the CHANNEL (up) position. Additionally, the PREswitch will tap the prelevel (and pre-mute) signal of whichever SOURCE you have selected-channel or MIX B. PRE (1&2) With the PRE switch (25) depressed, AUX SENDS 1 & 2 receive their input from a point before the channel fader and MUTE switch, and are not affected by changes in these controls. This is the normal switch setting for creating stage monitor and/or studio cue headphone sends. 9 24 PRE CHANNEL MIX-B SOURCE OUTPUT SECTION cussed below, allows you to assign submix buses within your L/R mix. The output section is the large area to the right of the input channel strips. It contains the master faders and metering, as well as the send and return masters, cue, monitoring and communication controls. LAYOUT AND FUNCTION MONO L & R The MONO L & R switch (4) functions ONLY when you have first depressed the L MIX or R MIX. If you’ve pushed L MIX or R MIX, pushing MONO L & R will assign the bus to both channels of the Left and Right Mix buses, instead of just the Left, or just the Right. This is also for submixing, but allows you to put your submix in the center rather than on either side. (Those of you with patch cords have probably realized you can patch the bus into a channel and do even more fun things, but we’ll talk about that later.) 8•BUS FADERS At the bottom of the output panel are the master faders for each of the eight buses (1). Each fader controls the level of its mix, with precise dB markings and a unity gain point marked on the panel. The fader is located in the circuit after the submaster insert jack but before the final line amplifier. There is an Assign section associated with each bus fader, detailed below. Note that no matter what the selection of the assignment switches, the output of each bus is always present at its Submaster/Tape Output jack and is monitored on its own bus meter. SOLO The SOLO button (5) solos the output of the bus fader. When any SOLO button is pressed, the SOLO LED lights. This is a pretty trick SOLO, too. If you have not pushed the MONO L & R switch, the SOLO sends the odd-numbered tracks to the left speaker and the even-numbered tracks to the right, whether or not the associated L MIX or R MIX is engaged. But if you have pressed MONO L & R, the SOLO circuit is smart enough to send the bus to both speakers and put the stereo image in the middle. You will be the envy of your neighborhood. L MIX and R MIX The odd-numbered buses have an L MIX button above their faders (2); the even buses have an R-MIX button (3). Pressing this button assigns the bus to the L or R Mix bus, respectively.

The fader controls the level of the L/R MIX bus, with precise dB markings and a unity gain point marked on the panel. This fader, like the bus faders, is located in the circuit after the L/R insert jack but before the final line amplifier. METERING +22dBu unbalanced. (You don’t want these to ever go on. If they do, try pulling down the L/R master fader a little.) Bus Meters 1-8 Directly above each bus fader is a peak-reading meter displaying the bus output level. Zero (0) on the meter references a level of +4dBu (1.23 volts RMS) at the output jack. Note: If the –10dBV switches are engaged at the Subgroup output jacks, then zero (0) on the meter references a level of –10dBV at those outputs. Note: When any SOLO switch is engaged, the SUBMASTER meters will be extinguished in order to divert your attention to the SOLO/MAIN meters (discussed below). MAIN OR SOLO LEVEL Meters The six auxiliary send outputs each have a master level control. Like any level control, turning the knob turns the volume up or down. However, the gain of the AUX Sends has been optimized at the unity (center detent) setting and should not need adjustment. The output of each bus is available at its AUX Send Out jack in the jack panel above. Additionally, AUX Sends 3 & 4 and AUX Sends 5 & 6 are fed as stereo pairs to the two PHONES SOURCE switching matrices, for headphone cueing purposes. The MAIN OR SOLO LEVEL meters display the L/R Main Mix levels and are similar to the bus meters, with these exceptions: • If a SOLO button is depressed, the meters display the output of the soloed signals; if not, the meters show the 1 level of the signal selected by the MONITOR SOURCE switches. In 2 other words, you are always metering what you’re listening to. LEVEL IMPORTANT: 5 3 When the console is in SOLO mode, 6 4 zero (0) on the SOLO/MAIN LEVEL LEVEL meters references the actual internal operating level, or 0dBu AUX SENDS (.775v). If you have just one signal in the main L/R path and you SOLO it, the meter level will jump up 4dB. PHONES MIX-B Don’t be alarmed. If you’re mixing on LEVEL LEVEL the L/R buses, that’s what you’ll meter. If you’re checking a tape playback, that’s what you’ll meter. When the meters are following the monitors (not in SOLO), zero (0) on MASTER the meter references a level of MIX B/MONITOR PHONES 1 +4dBu (1.23 volts RMS) at the main L/R outputs, just like the submaster + + 10 10 meters. 7 7 Note: The solo levels displayed on 4 4 2 2 the meters are PRE-solo level, 0 0 thus giving you an accurate 2 2 4 4 showing of the total level of the 7 7 soloed signals.This is also the way 10 10 20 20 to set initial console levels.

There is a solo LED (8) in the Send section, to help you locate what the heck you soloed. Note: The six AUX Sends are each mono signals, and they are soloed in mono. If you are using a stereo pair of sends for headphone cue, use the SOLO button in the PHONES 1 or 2 areas to check the sends in stereo. LAYOUT AND FUNCTION AUX Returns 1 & 2 (10) each have a stereo SOLO switch, a stereo LEVEL control, a BALANCE control and a bank of ASSIGN switches. ASSIGN (1 & 2) AUX Returns 1 & 2 are assigned in stereo pairs (Return 1, L & R; Return 2, L & R) to the L / R MIX buses or to odd-even pairs of the 8 submix buses (11). If you would like an effects return to accompany its dry signal on the multitrack (wet tracks), these are the returns to use. STEREO AUX RETURNS The AUX Returns (9) provide 12 additional inputs to the console for return from effects and reverb devices. The returns have switch matrices to allow easy assignment to headphones or mix buses. When any return is soloed, the solo LED in the lower left-hand corner of the Return area lights. For extra flexibility, the AUX Returns have been designed with an extremely wide range of available gain, offering as much as 15dB boost over unity. The return jacks are wired to provide both stereo and mono operation. See AUX Returns under JACK PANEL later in this section for details. Returns 3 & 4 AUX Returns 3 & 4 (12) each have a stereo SOLO switch, a stereo LEVEL control and a smaller bank of ASSIGN switches. ASSIGN (3 & 4) Returns 3 & 4 are assigned in stereo pairs (Return 3, L & R; Return 4, L & R) to the L/R MIX buses or to the PHONES 1 and PHONES 2 buses via respective banks of buttons for each return(13).

Returns 5 & 6 are permanently assigned to the L/R MIX bus. All returns are useful in a mixdown situation, as they are all assignable to the L/R mix. The MIX-B / MONITOR section (15) is quite straightforward. It offers a stereo level control for the MIX-B output, and an ASSIGN: MIX-B TO L/R MIX switch, which can add the MIX-B bus signal to the main L/R Mix. This essentially doubles the inputs available for mixdown. Avoid this pitfall: If you are monitoring the L/R mix in the control room and have the MIX-B to the L/R mix assigned, do not also select MIX-B in the monitor source switch matrix. If you do, MIX-B will sound twice as loud in the control room as it is in the L/R mix! PHONES The PHONES 1 (16) and PHONES 2 (17) sections are identical. Each contains a stereo level control for the headphones outputs, a stereo SOLO switch, and five pushbuttons to select from the following signal sources: MONITOR, MIX-B, AUX SENDS 3 & 4, AUX SENDS 5 & 6, and EXTERNAL. You can select any combination of sources. • The MIX-B, AUX SENDS 3 & 4 and AUX SENDS 5 & 6 switches are connected directly from the outputs of their respective circuits. • MONITOR takes the signal from after the MONITOR selection switches described below, and therefore carries the same signal that is applied to the control room monitors. (The PHONES section is not affected by the CNTL RM level control or the MONO switch in the MONITOR section, though.) • The EXTERNAL switch is connected directly from the L and R EXTERNAL INPUTS in the jack panel above. External is an independent cue channel for click tracks, etc. Its signal DOES NOT appear at any of the channels or buses. Note: If MONITOR is selected as a PHONES source and the solo button in the PHONES section is depressed, nothing will happen except that the Solo LEDs will light up. That’s because Solo is disabled under these conditions to prevent a feedback loop and its associated anguish. Note: If nothing is selected, signal may still feed the PHONES from AUX Return 3 & 4, via that section’s ASSIGN TO PHONES switches. MONITOR The control room monitors and the studio playback monitors are both controlled from the MONITOR section of the console (18). There is a stereo level control for the control room and another for the studio. Note: Fully clockwise equals unity gain. A bank of switches selects the stereo sources available to the speakers from L/R Mix, MIX-B, Tape and External. You can select any combination of signal sources. The L/R MIX and MIX-B switches are connected from the outputs of the L/R and MIX-B buses. The TAPE and EXTERNAL switches are connected from the 2-TRACK INPUTS and the EXTERNAL INPUTS, respectively, on the jack panel above. The MONO switch sums the left and right channels together to allow you to check your mix in monaural. This affects only the control room monitor speakers, the studio monitor speakers, and the L/R meters (although the meters are not monoed in solo mode.) SOLO The Solo section (19) contains the master level control for the stereo Solo mix. Set at the center detent, it will match the level of the soloed signals to the same signals unsoloed. This section also has the most obnoxious solo light allowed under international trade and safety regulations. We hope it gets your attention. The monitor switch in the phones section must be pushed in (selected) or the solo bus will not feed the phones. (By the way, if your console has two little tiny Death’s Heads above your RUDE SOLO LITE, you are very lucky. Only one in 10,000 Mackie consoles has what we call “Grim Greg” on it, and if you send in the top panel of your console with proof of purchase, we will ship postpaid to your door the bivalve pride of the Northwest, a Quilcene-smoked Geoduck filet, with our compliments!) TALKBACK The talkback section has four momentary pushbutton switches, which assign talkback to any combination of AUX Send 1, AUX Send 2, TAPE SUBGRPS (L/R MIX and the 8 SUBMASTERS) and PHONES/STUDIO. Try setting the talkback level at the center detent for starters. It can be tweaked up or down to your liking. Note: When talkback is engaged, only the control room outputs are padded by 20dB to avoid feedback, yet still allow the engineer to hear the musicians. The studio output is not padded. In situations where either the control room level is set way up, or there is a speaker pointing at the console, there may still be feedback. To prevent this, turn down the talkback level, the control room level, or change the angle of the control room speakers. The Talkback Microphone is located just above the L/R MIX fader. This ain’t no Neumann, so don’t attempt vocals through it (we wanted it to sound gritty and generally talkback-esque). Application of chewing gum to this orifice will degrade performance further to simulate really beat-up AM radio production studios. 13 LAYOUT AND FUNCTION JACK PANELS (INPUT STRIP & MASTER OUTPUT) PHANTOM POWER CHANNEL 24 MIC/LINE LINE IN BALUNBAL DIRECT OUT INSERT TIP = OUT RING = IN All of the inputs, outputs and insert points are located on the jack panels on the top and the rear panels of the mixer. An external patchbay is not required, although it does make life easier. Let’s start by listing what is NOT on the FRONT jack panel: • The console outputs to the multitrack tape recorder (the Submaster/Tape outputs) • The console inputs from the multitrack tape recorder • The balanced main L/R (XLR connector) outputs (on the rear panel) All other connections are made at the top of the front panel, either above the channel Input Strips or above the Output Panel. INPUT STRIP Each channel input strip has its inputs and outputs located directly above the strip. The connections are detailed next. PHANTOM POWER Microphone phantom power (+48 VDC) is applied to the channel strips in groups of eight. The phantom on/off switch for channels 1-8 is located above channel 8; the switch for 9-16 above channel 16, and so on. It has a “ramping” function, which means it gradually ramps from 0 to 48V when you turn it on, and ramps back down when you turn it off. This helps protect your microphones. We suggest that before plugging or unplugging mics, you turn off the PHANTOM power. Give it about a minute to settle while you get a Diet YooHoo or call your stockbroker. Then connect or disconnect the microphone(s) and turn PHANTOM power back on. CAUTION: After switching PHANTOM Power on or off, wait 1 minute before changing any mic/ line switch settings in that eight-channel block. Another safe alternative is to turn both TRIM and Channel Faders down for that bank of eight channels before switching. Let there be light (sockets) Additionally, one or two BNC connectors (depending upon the number of input channels on the console) are provided above the input strips for gooseneck lamps. The BNCs are wired with the center post at +12 VDC. Mackie doesn’t offer lamps, but most dealers do. We recommend LittleLite lamps #12G or #12G-HI (a high-intensity version). 14 Mic In The channel microphone input (1) is a standard 3-pin female mic connector (call me Cannon or call me XLR, just don’t call me late for dinner). Pin one is ground, pin two is signal high (+), pin three is signal low (–), as per the (finally) agreed-upon international standard. Note: Don’t use these XLR’s for line level signals — see “Line In”. Line In The channel Line Input (2) is a TRS (tipring-sleeve) balanced 1/4" phone jack, with ground wired to the sleeve, signal high (+) to the tip and signal low (–) to the ring. Nominal input level is +4dBu, with a wide range of levels accommodated by adjustment of the TRIM control. These jacks also accommodate TS (tip-sleeve) unbalanced 1/4" phone plugs. See Appendix A: Connections for more information. Direct Out The channel Direct Out (3) is a nominal +4dBu unbalanced TS 1/4" phone jack, connected to the output of the channel line amplifier post-EQ/post-fader/post-mute. The output signal of each channel strip is always available at the Direct Out jack. Using the Direct Out does not interrupt the normal signal flow through the channel. Channel Insert The channel Insert jack (4) allows you to insert external processing equipment (such as a compressor, gate, you name it) into the main signal path of the input channel strip. The insert point is after the FLIP switch (which also means that it is after the MIC/LINE or TAPE IN preamplifiers) but before the LO CUT filter, EQ and fader MUTE switch. The TRS jack is configured for the Tip (send), Ring (return) and Sleeve (signal ground). See Appendix A for more details on using external processing and channel inserts. OUTPUT PANEL The input and output jacks that correspond to most of the functions in the Output Panel are, logically, located in the jack panel directly above the Output Panel. The 8•Bus outputs to tape (and the inputs from tape) are located on the rear panel.

These patch points allow you to insert a serial L processing device (such as a compressor or an equalizer) into any of the 8•Bus submaster circuits. See Appendix A for more details on using external processing. The insert point is after the summing amplifier, but before the fader. Like the Channel Insert points, the connectors are 1/4" TRS jacks, wired unbalanced with the output or send signal on the tip, the input or return signal on the ring, and the sleeve common or ground. Note: These inserts can be used as pre-fader direct outs, using an unbalanced (TS) 1/4” plug in these two ways: • Plugs are inserted just to the FIRST click. There is no interruption of the signal; OR • Plugs are inserted all the way in to the SECOND click.This interrupts the signal and routes it ONLY to the device you’re sending to. 2 R The six AUX Sends (2) appear as six 1/4" jacks in a row, just underneath the Sub Inserts. AUX Sends 1 and 2 are balanced TRS outputs, wired tip to high (+), ring to low (–), and sleeve to ground. AUX Sends 1 and 2 are designed so that 1/4" unbalanced TS phone plugs can also be used, with no loss of level. AUX Sends 3 through 6 are unbalanced, with the tip high (+) and ring and sleeve tied together as ground. Nominal level is +4dBu. 4 R 5 R 6 R CNTRL RM OUTPUT L (MONO) AUX Sends 3 R MAIN INSERT (MONO) R R EXTERNAL INPUT R R MAIN MIX AUX RETURN L 2-TRACK INPUT R L R L STUDIO OUTPUT R MIX-B OUTPUT PHONES right return inputs and end up centered in your stereo image. When a jack is plugged into the Right input of the return, this mono feature is disabled: the left input is fed to the left return, and the right input is fed to the right return. Main Inserts On the upper right of the panel are two Main Insert jacks (4). These patch points allow you to insert a serial processing device, such as a compressor or an equalizer, into the Main L/R Mix. See Section 4 for more details on using external processing. The Main Insert’s insert point (try saying that fast three times backward) is after the summing amplifier but before the master fader. Like the Submaster Insert points, the connectors are 1/4" TRS jacks, wired unbalanced with the output or send signal on the tip, the input or return signal on the ring, and the sleeve common or ground. Control Room Output The two Control Room Output jacks (5) carry the signal for the Control Room speakers. They are 1/4" unbalanced, wired tip high, ring and sleeve ground. Nominal level is +4dBu. This is where you connect your control room monitor amplifier inputs. AUX Returns The AUX Returns (3) are stereo, with a L&R input for each return channel. Inputs are 1/4" unbalanced jacks, nominal level (+4dBu). One special feature: The Left input jack to each return is also labeled “MONO.” If you have only one return signal, plugging it into the “MONO/L” jack only will cause it to be connected to both the left and 15 1 2 TIP = OUT RING = IN SUBMASTER INSERT 1 2 3 1 2 3 4 5 6 5 6 7 8 AUX SEND 4 L (MONO) (MONO) L LAYOUT AND FUNCTION (MONO) L (MONO) (MONO) L (MONO) L L L L 1 R 2 R 3 R 4 R 5 R 6 R MAIN INSERT CNTRL RM OUTPUT (MONO) L R 2-TRACK INPUT MAIN MIX AUX RETURN L R L EXTERNAL INPUT R Main Mix The Main Mix jacks (6) on the top panel are 1/4" TRS unbalanced, with tip high, and ring and sleeve tied to ground. The nominal level is +4dBu. These two jacks carry the L/R Main Mix, for connection to your master 2-Track recorder’s inputs, for instance. The same Main L/R Mix is also available, fully balanced, at the two XLR connectors on the back panel. MIX-B Output The MIX-B jacks (7) are 1/4" TRS unbalanced, with tip high, ring and sleeve tied together as ground, nominal level +4dBu. These jacks make the MIX-B signal available for external patching. Phones The two Phones jacks (8) are 1/4" TRS stereo, with tip connected to left, ring to right and sleeve to ground. The final output of Phones 1 and Phones 2 appear here. These jacks may be connected to external power amplifiers for headphone distribution, or you may plug your phones directly into the jacks. There is plenty of level. In fact, you should turn the PHONES level down before you plug your phones in, and then bring the level up to where you want it. R L STUDIO OUTPUT MIX-B OUTPUT PHONES 16 R R L (MONO) R 1 2 Studio Output The two Studio Output jacks (9) carry the signal for the Studio speakers. They are 1/4" unbalanced, wired tip high, ring and sleeve ground, nominal level +4dBu. This is where you connect the inputs to your studio monitor amplifier. Alternatively, the Studio Output jacks can be wired to a second Control Room amplifier and set of speakers. Then, to switch between the two sets, turn the CNTRL-RM level control fully down and turn up the STUDIO level control — or vice versa. This concept is very handy during mixdown. It won’t work very well if you plan to use any of the talkback switches, as you would during tracking/overdubbing. 2-Track Input and External Input The 2-Track Input (10) and External Input (11) are 1/4" TRS unbalanced jacks, with tip wired to high and ring and sleeve tied together to ground. These inputs offer you the ability to listen to two mono or stereo sources directly, without patching through input channels. Either input can be connected to any stereo source you’d like to listen to. Usually, you will have the 2-Track Input connected to the output of your 2-Track master recorder, to check the mix. The inputs are directly wired to the “2-TK” and “EXTERNAL” source selection switches in the Phones 1 and 2 and MONITOR sections of the Output Panel. These are +4 dBu inputs. 21 19 17 13 15 11 9 OPERATING LEVEL CH. 17-24 IN –10dBV OUT +4dBu 22 20 18 7 5 OPERATING LEVEL CH. 9-16 IN –10dBV OUT +4dBu 16 14 12 10 8 6 +4 / –10 BALANCED / UNBALANCED +4 / –10 BALANCED / UNBALANCED +4 / –10 BALANCED / U TAPE RETURNS 17-24 TAPE RETURNS 9-16 TAPE RETUR REAR PANEL CONNECTIONS The connections to and from your multitrack recorder are on the Rear Panel of the 8•Bus Series. There are 24 or 32 Tape Return jacks (depending on the model) and 24 Submaster/Tape Out jacks. Tape Returns The Tape Return jacks (1) are 1/4" TRS balanced, with tip wired to high (+), ring to low (–) and sleeve to ground. These jacks are also wired to accommodate 1/4" TS unbalanced connections. Each jack is connected to the Tape input on the corresponding channel, and is selected by the FLIP switch on that channel. Connect the outputs of your multitrack recorder to the Tape In jacks. Note that they are grouped in sets of eight: 1-8, 9-16 and17-24. Tape return OPERATING LEVEL Nominal level for the Tape Return jacks is switched to either +4dBu (switch out) or -10dBV (switch in) in groups of 8 channels. If you aren’t sure of your multitrack recorder’s operating output level, check the specifications section of the recorder’s owner’s manual. Submaster/Tape Outputs The Tape Out jacks (2) are 1/4" TRS balanced, with tip wired to high, ring to low and sleeve to ground. These jacks are also wired to accommodate 1/4" TS unbalanced connections. The Submaster Outputs of the console appear on these jacks in the following pattern: RIGHT LEFT Console Bus 1: Submaster 1, 9 and 17 Console Bus 2: Submaster 2, 10 and 18 Console Bus 3: Submaster 3, 11 and 19 Console Bus 4: Submaster 4, 12 and 20 Console Bus 5: Submaster 5, 13 and 21 Console Bus 6: Submaster 6, 14 and 22 Console Bus 7: Submaster 7, 15 and 23 Console Bus 8: Submaster 8, 16 and 24 Connect the inputs of your multitrack recorder to the Tape Output jacks. Why are there 24 submaster output jacks on an 8-submaster mixer? This is called “triple-bussing.” When you send a signal to Submaster 1 output, for instance, it will appear at Submaster Outputs #1, #9 and #17. Now, whichever tracks on your multitrack are in RECORD mode will accept the signal, while the tracks in SAFE mode won’t. That way, you can feed a 24-track deck without having to constantly re-patch. Connect the Submaster/Tape Outputs to the corresponding inputs on your multitrack, using only Submasters 1 through 8 for an 8-track deck, or 1-16 for a 16-track deck. Submaster/Tape Output OPERATING LEVEL Nominal level for the Submaster jacks is switched to either +4dBu (switch out) or –10dBV (switch in) in groups of 4 channels (3). If you aren’t sure of your multitrack recorder’s operating input level, check the specifications section of the recorder’s owner’s manual. 8 7 6 5 16 15 14 13 24 23 22 IN –10dBV OUT +4dBu OPERATING LEVEL 21 4 3 2 1 12 11 10 9 20 19 18 17 +28dBu MAX OUT +4dBu BALANCED / –10dBV UNBALANCED MAIN BAL OUTPUTS SUBMASTER / TAPE OUTPUTS 17 IN –10dBV OUT +4dBu OPERATING LEVEL EXPANDER PORT +18V –18V +48V +12V +5V DC POWER IN RIGHT LEFT USE MACKIE 8•BUS EXPANDER CABLE ONLY!

Many of you reading this manual have a lot of experience in using large mixing consoles. For you battle-scarred pros, Section 2 and the Block Diagram will probably be all that you need to look at. Then there are those of you who have worked extensively with smaller mixers such as our 1604-VLZ PRO — but who have less experience with a larger, multi-bus console with lots of gazintas and gozoutas. For you, we recommend at least adding Section 4 (Recording) and/or Section 5 (PA) to your reading list. These chapters cover some of the more unusual or less familiar features of your new 8•Bus console. Finally, there are those who are either new to using mixers or just like to read even larger quantities of our glib prose. For you, we have provided this short section that discusses the basic concepts and procedures used in recording, mixing and sound reinforcement work. If you can make some sense of it, you’re ready for the next two sections, which relate these concepts to actually configuring and using a Mackie 8•Bus Series mixing console. Also, if the system Block Diagram does not look as familiar to you as the menu at McD’s, spend a little time in this section. GENERAL INFORMATION Here is a primer covering a few important ideas you should be on good terms with before you sit down to a mixing console. LEVELS Microphones have very low output levels. Power amplifiers have very high output levels. One of the functions of a mixing console is to amplify or attenuate (reduce) these signal levels properly. Since it’s easy to degrade the signal by not handling levels well, and since it’s your hand on the controls, you should be sure you know how much gain to apply and where to apply it. Noise Every electronic circuit produces noise or hiss or hash or buzz, and any noise present on the input of an electronic circuit will be faithfully passed through. Turn it up high enough, and you will hear the noise. Headroom Every electronic circuit also has a point of overload — a clip point, where the voltage simply cannot rise any higher, no matter what the input signal and your fader move would like. This overload, or clipping, will show up as toothgrinding distortion. Somewhere between the noise and the clipping is an optimum level for your signal: high enough above the noise floor to render the hiss inaudible, and far enough below the distortion point to allow range for loud peaks of music to pass without clipping. This safe operating zone might be called operating level or nominal level or zero or perhaps line level. The range between your operating level and clipping is called headroom, which defines just how tall your signal can be without having to duck for the rafters. Your mission as a designated Master of the Levels is to get the low-level signals up to line-level as soon as possible and to keep them there as much as possible. But don’t turn them up too loud. Unity Gain On a Mackie 8•Bus console, the easy way to do this is to set all the level controls according to the Sensitivity Adjustment procedure detailed on page 1. Metering When the meters read 0dB, the level will actually be +4dBu at the outputs (or –10dBV at the submaster outputs, if you’ve engaged their +4/–10 switches). Don’t pay too much attention to the meters. A meter is an aid, a window looking onto part of the dynamic range of your signal, and it will tell you if your level is in the ballpark, so to speak. Try to keep your signals in the middle range of the meters, for the most part. If the signal is always very low, you may not be getting the best noise figures you can. If the meter LEDs are always solidly lit from bottom to top, you are likely distorting both the console and your recording tape regularly. Keep the signal in the middle, with occasional peaks into the yellow. Remember, the top yellow LED of the meter (+10) represents an audio level of +14dBu, and the Mackie 8•Bus doesn’t clip until +28dBu. Even banging the meters hard, you still have around 14dB of headroom for your peaks. (The L/R meters have an additional red LED segment to show clipping at +28dBu.). There are not 19 GENERAL INFO many recorders, and no amplifiers, that can tolerate such high signal levels. Therefore, it’s best that the red LEDs never light up. But, if your music is sounding good, don’t worry if you’re in the yellow a lot or if some parts of the track hardly read at all. You’ll quickly get a feel for what works for you, when you can get away with really smacking the tape or the electronics too much. GENERAL INFO BUSES More often than not, the goal in a mixing console is to mix two or more inputs into one output. Like a coach who has two or more players to get to the same ballgame, console designers use a bus. Even Webster’s Unabridged Dictionary agrees, defining the word bus in electronics as “a conductor serving as a common connector for three or more circuits.” The Mackie 8•Bus Series has, in fact, many more than eight buses. The eight memorialized in the name are important, but there are also six AUXiliary buses, a pair of L/R Mix buses, the alternate pair of MIX-B buses, and a pair of Solo buses. We will try to be clear just what bus we are talking about when we do talk about buses. You can check EQ, possible distortion or buzz, or just listen to see if a particular mic is open or not. This function can also be handled by each channel’s –20/OL LEDs. See Section 2 “–20 and OL LEDs” for more details. When soloing more than one source, you can listen to the blend of just part of your mix: only the sopranos, for example, or just the tom mics on the drums. The solo circuits are designed not to interrupt the recording process. The solo bus signal is sent directly to the control-room monitors without affecting any of the inputs, outputs or recording buses. When you are mixing or monitoring with reverb, remember to not only solo the channel you’d like to hear, but also the AUX Return carrying your reverb. Otherwise, you will hear the channel soloed dry, without its echo. EQ Everybody knows what EQ is, but just in case you’d like a refresher, we’ll put in a few paragraphs here. Equalization (EQ) refers to purposely changing the frequency response of a circuit, sometimes to correct for previous unequal response (hence the term, equalization), and more SENDS AND RETURNS often to add or subtract level at certain frequenSends are outputs, and returns are inputs. So cies for a pleasing effect. why don’t we call them outputs and inputs? Bass and treble controls on your stereo are Well, actually, the terms send and return can EQ; so are the devices called parametrics and mean many things, but the way they are generally graphics and notch filters. used in mixing console parlance A lot of how we refer to is to refer to sends, which tap off equalization has to do with 3 HI MID VARIABLES a little of a signal to send to some what a graph of the frequency effects device (like a reverberaresponse would look like.

ParaHI MID Variable 2: Bandwidth metric EQs let you vary several SOLO EQ parameters at once. A filter Solo is a standard console is simply a form of equalizer function that allows you to listen that allows certain frequencies to one or more sources all by through unmolested and either themselves (soloed). reduces other frequencies or eliminates them entirely. HI MID Variable 3: Band Center 20 Fig.1 The equalizer on the 8•Bus Series combines several different types of EQ into five different sections. The HI MID EQ section is a fully parametric equalizer. This means all the significant parameters can be varied, as you can see in Figure 1. The boost or cut of this section, through a range of ±15dB, 2 LO MID VARIABLES is set with the top knob. The center frequency is dialed in with the middle knob, and can be set anywhere beLO MID Variable 1: Boost/Cut tween 500Hz and 18kHz. Finally, the bandwidth of the bell-shaped response curve around the selected frequency (also somewhat inaccurately referred to as a ratio known as Q) can be selected with the lower knob. The range is from as wide as 3 octaves to as narrow as 1/12 octave. Leave it at the center detent if you are unfamiliar with the bandwidth feature. This setting will give you a semi-parametric type of EQ. The 8•Bus console’s set of three HI-MID controls (boost/cut, frequency center and bandwidth) is VERY powerful in its effects. Rarely if ever will you need more than a few dB of boost and cut or, as noted above, will you want to stray from the NORMAL (2 octave) bandwidth until you gain some experience recording and mixing. The LO MID EQ section is called a semi-parametric equalizer, because the bandwidth is not adjustable (Figure 2). The frequency range is 45Hz to 3kHz and the bandwidth is fixed at 2 octaves.

Most tone controls on stereos are shelving EQs, often set at 100Hz for the bass and 10kHz for the treble.

When the EQ section is split between the channel strip and Mix B, the EQ IN/OUT switch will only shut off the HI MID and LO MID bands. The LOW CUT filter (also known as a highpass filter) reduces everything below about 100Hz. 75Hz is -3dB, and the lower the frequency, the greater the attenuation. The slope of the filter is 18dB/octave. Connectors If you’ve used a Mackie VLZ PRO compact mixer, you’re familiar with the various kinds of connectors used with a mixing board. If you’re new to this whole thing, review the drawings in Figure 4 on Page 21. They’re also described in detail in Appendix A on page 44 of this manual. 3-4 5 5-6 Multi-track Deck (RECORD) 10 7-8 A BIT MORE ON MIX-B/FLIP In Section 2, we described FLIP’s use during tracking and mixdown. 24 Before you actually get involved with recording, we’d like to spring a Channel Channel couple of block diagrams on you that Input Fader may clarify things further. Speaker Channel Channel Control Room The switch labeled FLIP selects the input Section Mix B/Monitor Tape Input Monitors that is actually fed into the channel fader (and the MIX-B control). As the label indicates, the MIC/LINE input (after Mic/Line preamp) is fed to the channel fader when the FLIP switch is in the up position (Figure 5). When FLIP is up, the Figure 5: FLIP/MIX-B signal path during tracking (“flip” switch up) channel is fed MIC/LINE and MIX-B gets TAPE. That way, you can use MIX-B to monitor the signal as it comes back from the recorder. This is the normal mode for tracking and overdubbing. In the down position, the TAPE return (the output signal from the corresponding track of your recorder) is fed to the channel fader (Figure 6). When FLIP is down, the channel input is TAPE and MIX-B receives MIC/LINE. That enables you to use each channel’s MIC/ LINE input for another input during Channel Multi-track Deck Mixdown Deck Channel Fader (PLAYBACK) Tape Input mix down. Thus down is the normal Channel Channel position for mixing.

Not much advice needed for that. But since you’ve bought such a large mixing console, we expect you’ll occasionally be doing pretty big sessions. This section will describe at least one way of approaching a large session— for example, a big drum set, bass, guitar, piano, scratch vocal and horns, with background vocals and synthesizer overdubs. Let’s assume there is a 16-track recorder already patched in to the first 16 Tape In and the 16 Tape Out jacks on the 8•Bus Console. There is a set of Master Tracking, Overdub and Mixdown drawings farther on in this section for general reference. SETUP Okay, now let’s get ready for your session. Make a diagram of your studio setup showing mic positioning. Then assign an input channel to each mic. Trying to make your microphone-to-input layout sensible now will avoid confusion later. Group similar instruments together. If there is a left-toright pattern to the mics (like drums mics or a vocal group), keep the same left-to-right sequence on the console. Plan your basic track assignments the same way. It’s very confusing to have inputs randomly strewn across a mixing console. Now, normal your console (also called “zeroing”). This means check the position of every switch and every knob to be sure they are in the normal position. Your normal may be different from someone else’s, but generally it means all switches off or up, all knobs either all the way down or at their Unity detent. If you are working in a certain mode, say, for example, all AUX 3-4 SHIFT switches in TAPE, this is the time to set them all. Lay a piece of 1/2" or 3/4" white paper tape across the top of the input faders and label all your inputs. (By the way, avoid masking tape. It will slime your console. Take the time to go to an art supply store or a recording supply store and get some better-quality “low tack” tape.) Since your multitrack returns will be coming into the MIX-B inputs on some of the same input strips, you might want to divide your label into multitrack track labeling and input labeling. See TRACKING drawings 1&2 on pages 25 and 26. If you have any careful submixing to do during the recording, you might want to lay strips of 1/4" white paper tape alongside each fader slot (bus faders too, if you need them). Then you can mark your place as you rehearse your fader moves. RECORDING AND OVERDUBBING Using Buses If you have to combine two or more inputs into one output (two trumpets on one track, five drum mics panned across a pair of tracks), you must assign the inputs to a common bus or pair of buses. If you have only one source going to one tape track, you have a choice: you can assign the channel to the bus feeding that track, or you can patch the tape track into the channel’s Direct Out. Rationale for using a bus: • It’s there, it’s easy, it sounds great. • You meet interesting people on the bus. Rationale for using a Direct Out: • You’ve already assigned all eight of your buses to other duties. • You are a purist and you think you can hear the additional circuitry used in a bus. Monitoring The most straightforward way to monitor during a recording or overdubbing session is by listening to the output of the recorder, played through MIX-B. Properly configured, your recorder will automatically switch between source and playback as you put the deck into stop, play, fast wind, record and so on. That way, you’re always hearing your instruments after they travel through the multitrack deck, regardless of whether or not the tape is rolling. MIX-B allows you to set up a custom mix of the tape tracks, independent of your recording levels. You can set level, pan, reverb and even EQ in your monitor mix while you record. You can even patch a cassette recording into the outputs of MIX-B for a rough mix of the session. Both the FLIP and MIX-B SOURCE buttons should be in their up positions. This connects the Tape In amplifier to the MIX-B level control, and MIX-B will monitor the recording machine. Cue Mix Initially, as you are setting up, set the Phones source to the MIX-B selection. This way, the musicians will at least have something to listen to right away so they can tune up and rehearse, 23 RECORDING FOLLOW THIS LEVEL-SETTING PROCEDURE FOR EACH CHANNEL IN USE: 1. ■ Assign signal to channel fader: • If channel will be used with a microphone, MIC/LINE switch should be up & FLIP switch should be up. • If channel will be used with line input, MIC/LINE switch should be down & FLIP switch should be up. • If channel will be used with a tape input, the FLIP switch should be down. RECORDING 2. Set channel strip controls as follows: ■ TRIM pot all the way counterclockwise (+4dB) ■ AUX SEND controls all the way counterclockwise (off) ■ EQ switch up ■ LOW-CUT switch either on or off (on recommended for mic inputs) ■ Channel fader at UNITY ■ SOLO switch down 3. ■ Make appropriate “noise” into the channel input. For example, have a performer play/ sing/strike something or someone, etc. at the level they’re going to record or perform. Don’t just play a single sustained note, but rather, jam away as you would be during recording or performance. If the channel is being used for a tape input during mixdown, roll an already-recorded track from your recorder. 4. The channel’s –20dB LED should light. The L/R main meters will show the actual internal operating level of soloed signals. Now you will optimize levels. 5. ■ • For mic or line inputs, adjust the TRIM control clockwise to get peaks that regularly hit 0dB on the L/R meters. OR ■ • For tape inputs, set the +4/–10 switch on the console back panel to its in position (–10) if the signalpeaks are below –10dB on the L/R main meters. 6. If desired (optional): ■ Press the EQ switch in. ■ Adjust the channel strip’s EQ to about what you will be using during the session. ■ Re-perform Step 5. 7. ■ Return the channel strip’s SOLO button to its up position. 8. ■ Repeat Steps 1-7 on the next channel that is being used. providing all your chosen tracks are in record mode and auto-switching to input when tape is not rolling. Keeping the Phones on MIX-B may work for the entire session, but usually the musicians will want one or even two custom mixes. The bass player and drummer may want bass and drums featured very loud in their cans, which may be killing the vocalist. Likely, as soon as you are close, you will be required to come up with some new cue feeds for the players. AUXiliary Sends 3-4 and 5-6 are designed to set up two different cue mixes from the same source as MIX-B, which should be the signal from your recorder. Simply push the SOURCE button by Sends 3-4-5-6 down to the MIX-B position, and push the PRE button down (to bypass the MIX-B level control). With the system configured like this, you will be able to send a custom mix from each tape track to either Sends 3-4 or Sends 5-6, depending on the position of the AUX SHIFT switch. It’s like having an extra Mix B section. Sends 3 and 5 are set to feed the left headphone, and 4 and 6 the right headphone. An equal setting on both knobs will place the sound in the center of the image. Additional Note: You can modifiy the channel Aux 1/2 sends to source the pre-fader information from the tape returns. This would provide an additional two aux sends that could be used as cue mixes from Mix-B (tape returns), and allow all six aux sends to access Mix-B during tracking or overdubbing for cue mixes as well as effects. Instructions for this modification can be found on our website at www.mackie.com (click on Support). Or you can call Tech Support at 1-800-258-6883 for assistance. Wet or Dry Monitor? Usually, you will not record wet (with reverb) onto your multitrack master. You can’t undo it later. However, it is nice to hear a little echo on the tracks as you are working, and with the 8•Bus Series, you have the option of wet monitoring. Since you are using MIX-B as your monitor submix, you should derive the reverb send from the same source. When the SOURCE button next to Sends 3/4/5/6 is depressed but the PRE button is not, the sends are connected after the MIX-B level control and make great wet monitor reverb sends. Once you have your sends happening, you can assign the return from your reverb into the headphone cues by using Stereo Returns 3 or 4, which can directly assign into the phones. (Even if you are using Send 6, there is no reason not to patch the output of the reverb into Returns 3 & 4. The Send and Return numbers do not have to match.)

You have three choices: • Assign MIX-B to L/R Mix in the MIX-B master section. Then, select L/R Mix as your only source in the monitor section. Finally, use Stereo AUX Returns 1-6 to bring the reverb into the L/R Mix buses. Make sure that none of the channel L/R switches are engaged. There is no disadvantage to this patch, unless you are already using the L/R Mix buses for some other function. • Patch the returns into unused tape returns, using the Tape In jacks on the rear of the console. Then route them into MIX-B, just as if they were additional tape tracks. • Patch the returns into unused channel strips, using the Line In jacks. Then you can route the reverb anywhere your heart desires. Overdub, Anyone? See the OVERDUB drawings on page 30 and 31. Once you’ve got your basic tracks down, take a moment and log all your settings, right down to headphone sends and outboard compressor thresholds. You may be back next week doing it all over again, and you won’t remember it all. It seems some engineers use a camera for this step, but our Polaroids never come out that well. One easy way to do this is to copy the 8•Bus panel layouts from the end of the manual and mark your settings on them in color. Now, normal all the channel inputs and EQs and sends—anything that does not affect your MIX-B monitor and cue submix. Do not change the FLIP switch settings yet. Then, pick a convenient input channel or two and use them as your input for overdubs. As you record on different tracks, just reassign the bus Let’s Record! outputs from the channels, no sweat. Remember, with the triple busing feature, explained in SecHere’s one way to set the board up (another option is shown in the hook-up drawings…either tion 2 (“Submaster/Tape Outputs”), you won’t have to repatch anything to feed up to a 24-track works just fine): recorder.

Recording and overdubbing require care from the recording engineer, but the focus really has to be on the performances. It’s important to get a good sound, but it’s more important to keep the musicians really in it, keep the pace up, be ready to snag that killer track when it happens. Good mixing, however, focuses solely on the engineer and requires an emphasis on precision 27 RECORDING and meticulous setup. Creatively, you must blend the tracks so they at least sound like music again; technically, you must take into account the sound of home and car speakers, mono compatibility, human perception changes under different listening conditions, matching similar product in your market, not to mention tonal and level balance between songs, and meeting the criteria for tape and disc mastering. MIXING SETUP RECORDING Clean and align your mixing machine according to the manufacturer’s instructions. If it’s a digital machine, sacrifice a full floppy disk in its presence to ensure smooth operation during mixdown. Group all your inputs in some sensible way, keeping drums, vocals and synths next to each other. You’ll probably have to repatch some of your tape returns to do this. Lay a strip of 1/2" white tape across all the console input channels for labeling. Put 1/4" strips of tape vertically along each fader to mark levels. Pick a Model Get copies of music you’d like to approximate in your mix, and patch the CD or DAT machine into the external jacks on the console. Then you can A-B your mix against your model at the flick of a switch to see if you’re really getting that snare sound or not. Consider Compression You can mix an entire project without a lick of compression; many engineers do. The dynamic range of a CD can certainly handle it. But consider: most people listen to what you mix under less than ideal conditions. There is background noise and road noise, and most people don’t listen as loud as you mix. A little gentle compression, whether on individual tracks or on the entire mix, can reduce the dynamic range a bit and pull your mix together. Also, if you want to simulate what your mix will sound like over the airwaves, you can compresss the heck out of it, like they do. They use very fancy compressors, but any compressor will give you an idea of what will happen. This is good for checking things out, but not for your final mix. DOING THE MIX Assuming the console has been normalled, all you have to do to get ready to mix is to engage the FLIP and L/R MIX switches (unless you are using the submasters to group channels) on each of the input channels and select L/R MIX as your Monitor Source. Pull all the channel input faders down. 28 There is a tendency for levels to creep upwards as you add more and more tracks to your mix. One way to keep a handle on this is to set the L/R master fader a few dB above unity, and to set your initial monitor levels pretty high. As you get closer and closer to your final, you can ease the monitor levels down and easeup the master fader to unity, which is where it should be. If your multitrack tape machine will do it, put it in the loop mode so it will just play the song over and over. Start mixing a group of tracks that run throughout the song, maybe drums or the rhythm section. Set the panning, level, EQ, reverb and delay, and bring in more tracks as the mix begins to jell. Don’t make any level marks on your fader tapes yet, but as the mix comes together, try to note which sections work without a lot of fader moves. Look for what appears to be the loudest part. Sometimes turning the Control Room Level way down, so the mix is very quiet, will reveal what sounds are clearly louder than others. Now take a listen to your model on CD or DAT. Make some adjustments in your mix to put it closer. When you think it’s getting reasonable, find that loudest section that you located, and pull the master fader back to get the levels close to normal on the main meters. Then go to the section that works by itself and start making little marks on the fader strips. You’re getting close. Listen to the model again. Start making more marks for the moves. Repeat until it sounds like a hit. Serves four adults. Using External Processing Compressors, gates and equalizers are generally inserted into the signal path. They are referred to as “serial devices,” used in series with the signal path. All the signal goes into the device, then out and back to the mixer’s signal path. Reverb, echo, delay, aural excitement and spatial enhancement are usually set up as send/ return devices. These are referred to as “parallel devices.” Some amount of signal is “borrowed” from a channel via an AUX Send, sent to the device, processed and returned to the mixer as a new, wet signal via the AUX Returns, to be mixed with the original, dry signal. Insert Devices A compressor/limiter after EQ will compress differently than one inserted before the EQ. A compressor/limiter inserted before a master fader will limit consistently, but one after the same fader will effectively have its threshold moved by the fader level. None of these choices are right or wrong, they just have different effects.

CHANNEL MIC –10 LINE S /LI There are three common points for inserting processing devices in the signal path during mixing: • In a pre-EQ channel insert point (for one channel only) • In a sub-master bus insert point (for a subgroup) • In the L/R Mix insert point (to affect the whole mix) Send / Return Devices Since you’re not setting up custom phone cueing while you’re mixing, you will normally have all six AUXiliary sends available. Use a couple as your primary reverb sends, perhaps one for a bright plate and the second the same with a slap or predelay. That leaves you four for special effects. You can also use the MIX-B outputs or an unused 8track bus as additional sends. If you only need to put the effect on one channel, you can use the channel Direct Out as a send (and the effects input level as the send level). Lots of options at this point. Post-fader is almost always the preferred mode for reverb sends. Keep the sends in post unless you don’t want the reverb to follow the fader moves. If you want the “wet” sound (lots of reverb), turn the fader down a bit, and turn up the appropriate AUX Send to compensate. Now you have less “dry” signal and more “wet.” Dreamy! Patch the output of the reverb units to the AUX Return inputs, which offer level and pan controls, and assign switches to put your effect where you want it. Notice that each of the six returns has two inputs, for a total of twelve. This allows you to send and return to six stereo effects units and bring all the reverbs and echoes back in. Note: There is no rule against sending on 3 and patching the returns into 5 and 6. If your reverb has stereo inputs, try feeding a mono signal, using just one AUX Send, into its “mono” input. Most reverbs are not true stereo, input-wise. You’ll lose nothing and get back an AUX Send. If you are using a mono effect or only one channel of a stereo effect, using only the Left input jack of a return will place the effect in the center of your mix. If you use the Right jack, the effect will be placed on the right side in your mix. To put the effect on the left side only, patch the return into the Left jack, and place an unwired dummy plug into the Right jack. That will defeat the left-goes-to-center normalling and allow the signal to remain on the left in the mix. As mentioned above, you can use the AUX Return inputs as additional inputs to the console if you wish. You can also use channel input strips as reverb returns. Simply patch the return into a Line Input, if you have enough inputs to handle this. (Bonus: you now have console EQ available on your reverb return. Be sure the AUX Send feeding that reverb is turned fully down on the channels being used as reverb returns. If you don’t, every dog in the neighborhood will want to hump your leg.) Using Subgroups There will be many times during mixing that you will want to set up subgroups within your mix. A subgroup allows you use just one or two (for stereo) faders on a larger group of tracks (say, drums or horns or background vocals). This makes for easier control (especially if you do not have automation), and also allows you to patch a single (or a matched pair for stereo) EQ or compressor on the set of tracks. The Mackie 8•Bus console offers you several options using subgroups, depending on the situation. • To assign channels to a subgroup during mixing, first de-assign the channels you want to subgroup from the L/R MIX. Then choose the bus or pair of buses you’d like to use as a subgroup and reassign the channels to that subgroup. The channel pan controls the selection of buses for a mono subgroup, and the position between buses for a stereo subgroup. For example, if you want a mono subgroup using Bus #1, select 1/2 assign and pan those channels fully left. Now, in the Assign area above the submaster faders, select the combination of L MIX, R MIX and MONO L+R switches that suit you. The L MIX and R MIX switches are upstream of the MONO L+R switches, and must be engaged to make the Mono switches work. Compressors or EQs can be inserted into the Submaster Insert jacks at the top of the Output section. • Another option is to bypass the bus assign switching above the 8•Bus masters and instead patch the output of the bus(es) back into the inputs of a channel fader or two. Then assign those channels only to the L/R MIX to reinsert the subgroup into the mix. If you have enough input channels, this configuration gives you console EQ and Sends on your subgroup, which may be handy. Finding More Inputs: MIX-B to L & R Buses There are never enough tracks on your recorder, and there are never enough inputs on your console. It’s always the case. Your unbridled creativity will find ways to use up everything, whether you are routing the vocals through a pair of Leslie speakers or keying a gated set of 35 RECORDING reindeer bells with the snare signal. The Mackie 8•Bus consoles can’t give you the infinite number of channels you dream of, but you can very easily double the number of inputs by using the MIX-B buses. If you are mixing off tape as we set it up a few pages ago, you have engaged the FLIP switch to put the tape returns into the main channel fader and EQ. The FLIP switch also switches the Line Input to the MIX-B circuitry, and that provides your extra inputs. You can get an AUX Send for the extras using the SOURCE switch in the AUX Send 3/4/5/6 area, and you can SPLIT the EQ if you need to. Check over in the MIX-B/MONITOR section above the Sub meters and you’ll see the MIX-B TO L/R MIX ASSIGN button, which will bring all your MIX-B inputs back into the main mix. Voila! Twice as many inputs! Monitoring and Levels Check your speakers and amplifiers to be sure that they’re balanced left-to-right and mounted symmetrically to your mixing position. A 2dB shift in monitor balance will produce a 2dB shift in the opposite direction in your mix. Also, check your speaker polarity (sometimes inaccurately called phase). This is a basic thing we all know about, but it’s amazing the times we’ve found studio speakers (especially nearfield monitors, which are often plugged and unplugged regularly) connected with opposing polarity. You should train your ears to notice outof-polarity conditions instantly. It’s easy to hear (to us it sounds like a combination of not hearing enough bass and feeling like our eyes are slightly crossed), and getting polarity right will save you much grief in mixing. Remember that you need to mix so that your music or program sounds good on anybody’s system. Be sure you have some real-world monitor speakers in addition to the monitors you like so well, and check back and forth frequently. See Section 2 (“Studio Output”), for details on how to use two sets of control room monitors. Check at different monitoring levels, too. A mix that sounds great loud will not necessarily sound good at low volume. Listen at a barely audible level from time to time. You should still be able to hear the essential pieces of your mix. Also, check your stereo mixes in mono regularly during your mix. Much television and radio is still heard in mono, and your mix has to sound its best both ways. Take a hint from the film mixers and set your dialog or lead vocals to about 85dB/c at the mixing position. This is a moderate, normal volume; not quiet but definitely not thundering. If you 36 have a sound pressure meter available you can take a measurement to get a feel for how loud 85dB is. If you don’t, run down to Radio Shack and say: “I want #33-2050 or #32-2055. Here’s $34.99 or $49.99 plus applicable taxes.” Every set of self-respecting ears should own one. This monitoring volume will keep you honest, and keep your mixes balanced for playback. Sure, listen at very low levels, too, and crank it from time to time to remember why you’re in this line of work, but stay at the moderate 85dB/c setting most of the time. You will save your hearing and also make better mixes. A Word About Automation There is an optional MIDI automated mixing capability that will be available for the Mackie 8•Bus Series Consoles, so we won’t talk about automated mixing here. That’s in the manual that comes with the automation components. For those of you without automation, there is hope. Billions and billions of great mixes have been done on non-automated consoles. Here are a few tips: • Use subgroups, discussed earlier. • “Mult” tracks that need drastic EQ or reverb changes to two channels, and alternate between them with the MUTE switches. (Multing means connecting one output to two or more inputs by simply paralleling the connections. Some patch bays have paralleled mult strips available. You can also make mult boxes or just use “Y” adapters. Note: Never mult two or more outputs into one input. That’s what mixers are for. Only mult one output into two or more inputs. See Appendix A: Connections.) • Enlist several sets of hands. • And last, most terrifying, but most powerful and effective: edit between sections of your mix. It would be wise to make two passes of your mix before you chop up your only one. If you’ve been wildly editing mixes for years and years, you know what we’re talking about. If not, learn to do it. Whether you do it digitally or you use a razor blade, you can fix that tiny detail in an otherwise perfect mix; you can mix a complicated track in sections rather than like a marathon; you can go from 200 instruments to a single whispered vocal and back again in a heartbeat; you can even fix a mix weeks later without losing the original magic—you just remix the one chorus that needs fixing and cut it in. SECTION 5: PA AND SOUND REINFORCEMENT APPLICATIONS WITH THE MACKIE 8•BUS CONSOLE One of Mackie Designs’ primary product philosophies is to make its mixers as multi-purpose as possible to make them more affordable. This sounds like a contradiction in terms, but it isn’t. By creating consoles JUST for recording and other models JUST for PA, other companies complicate the manufacturing process and reduce their economies of scale. We designed the 8•Bus Series from the ground up for both recording and PA sound reinforcement applications. If you have any doubt as to the durability of your new console, just think of how many smaller Mackie mixers have logged literally millions of air miles on grueling tours (and how many vintage Tapco mixers that Greg Mackie designed are still around and in day-today use). From a features standpoint, Mackie 8•Bus Series consoles are easy to configure for public address and sound reinforcement applications, whether you are mixing the house, stage monitors or both at once. Use the L/R main mix buses and your main L/R outputs as your main signal path. If you want a headphone cue mix, either patch the Control Room outputs to a suitable headphone amplifier, or select MONITOR as the source for Phones 1 or Phones 2. This will allow you to listen to any source you can select for the Control Room. You can also use the solo buses as headphone cue. If you prefer, you can modify the solo circuits for PFL (Pre-Fade Listen). SETUP Refer to the STEREO LIVE MIX drawings on page 40 and 41. You should normally use the L/R Mix buses as your Main or House feed. Patch out from the L/R outputs (peferbly the balanced XLR outputs) into the input to your amp stack (usually your House graphic equalizer). Any of the AUX buses can be used to feed a stage monitor mix, but AUX Send 1 and 2 are balanced, so they would be the best choice for several different stage monitor mixes. Set the AUX Sends in each channel to PRE and patch the AUX Send outputs to the appropriate amplifiers. If you need to provide a simultaneous mix for a stereo recording, use the MIX-B buses as described in MAKING A SIMULTANEOUS RECORDING. FOLLOW THIS SENSITIVITY ADJUSTMENT PROCEDURE FOR EACH CHANNEL IN USE: 1. ■ Assign signal to channel fader: • If channel will be used with a microphone, MIC/LINE switch should be up & FLIP switch should be up. • If channel will be used with line input, MIC/LINE switch should be down & FLIP switch should be up. 2. Set channel strip controls as follows: ■ TRIM pot all the way counterclockwise (+4dB) ■ AUX SEND controls all the way counterclockwise (off) ■ EQ switch up ■ LOW-CUT switch either on or off (on recommended for mic inputs) ■ Channel fader at UNITY ■ PAN pot hard left or right ■ SOLO switch down 3. ■ Make appropriate “noise” into the channel input. For example, have a performer play/ sing/strike something or someone, etc. at the level they’re going to record or perform. Don’t just play a single sustained note, but rather, jam away as you would be during recording or performance. 4. The channel’s –20dB LED should light. The L/R main meters will show the actual internal operating level of soloed signals. Now you will optimize levels. 5. ■ Adjust the TRIM control clockwise to get peaks that regularly hit 0dB on the L/R meters. 6. If desired (optional): ■ Press the EQ switch in. ■ Adjust the channel strip’s EQ to about what you will be using during the session. ■ Re-perform Step 5. 7. ■ Return the channel strip’s SOLO button to its up position, and set the PAN pot back where you found it. 8. ■ Repeat Steps 1-7 on the next channel that is being used.

RECORDING+8tk RECORDING 2: THE BOARD CHANNEL MIC –10 LINE S/LI HOUSE AND MONITOR MIX TOGETHER PA & SR It’s a big board, but it’s the only one you own. So you find yourself mixing house and monitors all from the same panel. First, let’s take a moment and set everything up sensibly. Just like in a recording session, it’s good to group your inputs and sub-mix buses by instruments, stage position or whatever else suits you. Try to keep the drum mics next to each other, the vocals together and so on. Label your cables, color-code your windscreens, lay tape across the arm rest, make a cheat sheet, iron your shorts, give yourself a break. It can be confusing enough mixing a big show without wondering which channel is which. Using AUX Send-Return loops and inserting outboard gear is the same as when recording, unless you want to use the AUX Sends as independent cue mixes, by engaging the PRE switch for those AUX Sends. Subgroups can be very helpful in Sound Reinforcement (SR) work. Remember, when you assign a channel to a subgroup, de-assign that channel from the L/R Mix. Headphones If you like to check things out in your phones, and especially if you want to use the 8•Bus solo or (modified) PFL functions as a cue circuit, set your phones up like this: • Be sure the MONITOR SOURCE switch is set to what you want to listen to (usually L/R Mix, your House feed). You can keep the two Monitor LEVEL controls turned down, though, because you are not feeding amplifiers from the Control Room or Studio outputs. • Plug your phones into one of the two Phones output jacks; let’s say Phones 1. Now select MONITOR on the PHONES 1 SOURCE switch. That should give you L/R Mix bus plus solo. See, the solo bus only feeds the Control Room and Studio Speakers circuits, so we had to poke a few buttons to make it work. MAKING A SIMULTANEOUS RECORDING You’re all set up, ready to go, when the band’s manager comes up to you with a DAT machine and goes “The producer wants us to send him a recording of tonight’s gig,” and you go, “I’ll patch it in to the house mix,” and he goes, “No, I’d rather get a special mix just for the tape,” and you roll your eyes and go, “You should really get a remote truck,” and he rolls his eyes and goes, “Here’s the tape. Make it good and we might hire you next time.” 42 Piece of cake. Refer to the drawings on pages 40 and 41. MIX-B to the rescue! L/R Mix is your house mix, you will use the AUX buses for stage monitor mix, and MIX-B will provide a stereo recording feed. Simply depress each of the MIX-B SOURCE switches to CHANNEL, patch the MIX-B outputs into the recorder inputs and set up your recording mix with the MIX-B level controls. To monitor, select MIX-B on the Phones output you’re using and route the output of the recorder back into EXTERNAL to check playback. It’s true, there are no meters on the MIX-B buses. Try using the recorder meters. If you can’t see them from where you sit, there are a couple of patches you can try to get metering: • Since you’re not using the CONTROL RM or STUDIO outputs, you can use the MONITOR section for metering only. Simply engage only the Mix-B Switch in that section. • If you have two free submaster buses, patch the MIX-B buses into the submaster insert point. (Push the 1/4" plug only halfway in to the Insert Jack, to the first ‘click.’ See Appendix A: “Connections” for details.) Set the submaster faders to –6dB to adjust for the insert point gain difference. Now you will have MIX-B levels showing on those two submaster meters, and you can use the SUBMASTER OUTPUTS as feeds to your recorder. • If you have the optional meter bridge fitted and you have two extra inputs, patch the output of MIX-B into the open channels (either Line In or Tape In, depending on how you have set the global source switch on the meter bridge), set the levels at unity and watch those two channel meters for recording levels. You can now use the two channel’s DIRECT OUTS as feeds to your recorder. Make sure all the channel bus and AUX assign switches and controls are off, so you don’t accidentally assign your signal back into the mix. Also, this way you could add a little EQ or compression via the channel inserts. • In either of the above cases, you may want to keep the extra circuitry out of your recording signal path. If so, just mult the MIX-B outputs to both your recorder and to the patch point for metering. HOUSE MIX ONLY or MONITOR MIX ONLY Much easier than both at once, but requires two mixers. Simply split the mics, set one mixer up for house (on the L/R Mix buses, as above) and the other one up for stage monitor. If you need to do some combination of house/recorder feed or vocal/drum/keyboard monitors, divide the functions up between L/R Mix, AUX buses and MIX-B buses as described above. Mic Splitters If you are using one mixing console for your main or house mix and another for stage monitors, the best way to distribute the microphone signals to both consoles is by using a good quality mic splitter box. Splitters use transformers specially designed to split the signal and keep the impedance match correct while rejecting noise and preventing ground loops. You can get splitters with as many input channels as you need, each with from two to five outputs for each mic input. Mic splitter transformers are expensive, but are well worth the investment. They will provide the most consistent trouble-free performance with multiple mixers. If you need to split your inputs but do not have splitter transformers, you can make a special harness of cables to split out of the Mackie channel insert. This technique is not always as flexible or ground-loop-proof as splitter transformers, but is much less expensive. See Figure 11 in Appendix A: “Connections.” PA & SR FINDING MORE INPUTS You bought a 32-channel mixer and you still don’t have enough inputs. Well, before you go to the bank again, remember that the Mackie 8•Bus Series has some options for you: • You can get up to 32 additional line inputs using the Tape In to MIX-B path. You can even split the EQ and Aux Buses to the MIX-B inputs if you want. Then assign Mix-B to L/R Mix. • Any unused AUX returns (there are 12 inputs) can be used as additional line inputs. • In a pinch, you can use the eight Submaster’s inserts providing the sub is currently unused (no channels assigned to it). Use a 1/4” TS cable and plug in only to the first click. Signals entering here will be kicked up by +6dB. 43 APPENDIX A: Connections “XLR” CONNECTORS Mackie mixers use 3-pin female “XLR” connectors on all microphone inputs, with pin 1 wired to the grounded shield, pin 2 wired to the “hot” (positive polarity) side of the audio signal and pin 3 wired to the “cold” (negative polarity) side of the signal (Figure 7). Use a male “XLR”-type connector, usually found on the nether end of what is called a “mic cable,” to connect to these inputs. Mackie occasionally uses 3-pin male “XLRs” for balanced line outputs. The Main L/R Outs on the 8•Bus, for example, are available on XLRs. These are also wired pin 1 ground, pin 2 high and pin 3 low. 1/4" TRS PHONE PLUGS AND JACKS “TRS” stands for Tip-Ring-Sleeve, the three connections available on a “stereo” 1/4" phone jack or plug (Figure 8). TRS jacks and plugs are used in several different applications: • Stereo headphones, and rarely, stereo microphones and stereo line connections. When wired for stereo, a 1/4" TRS jack or plug is ADD-ONS connected tip to left, ring to right and sleeve to SPECS ground. Mackie mixers do not directly accept ETC. 1-plug-type stereo microphones. They must be separated into a left cord and a right cord that are plugged into two channels. • Balanced mono circuits. When wired as a balanced connector, a 1/4" TRS jack or plug is connected tip to signal high, ring to signal low, and sleeve to ground. • Unbalanced Send/Return circuits. When wired as send/ return connector, a 1/4" TRS jack or MONO PLUG plug is connected Channel Insert jack tip to signal send Direct out with no signal interruption to master. (output from Insert only to first “click” mixer), ring to signal return (input back into MONO PLUG mixer), and sleeve to ground. Channel Insert jack Direct out with signal interruption to master. Insert all the way in to the second “click” STEREO PLUG Channel Insert jack For use as an effects loop. (TIP = SEND to effect, RING = RETURN from effects) 44 1/4" TS PHONE PLUGS AND JACKS “TS” stands for Tip-Sleeve, the two connections available on a “mono” 1/4" phone jack or plug (Figure 9). TS jacks and plugs are used in many different applications, always unbalanced. The tip is connected to the audio signal and the sleeve to ground. Some examples: • Unbalanced microphones • Electric guitars and electronic instruments • Unbalanced line-level connections SWITCHED 1/4" PHONE JACKS 1/4" phone jacks can incorporate switches that are activated by inserting the plug. These switches may open an insert loop in a circuit, change the input routing of the signal or serve other functions. The Mackie 8•Bus Series uses switches in the channel and bus Insert Jacks, and in the mono/stereo AUX Return Jacks. See Special Mackie Connections on page 45. We also use these switches to ground the inputs of most line level ins/outs when nothing is plugged into them.

Mackie takes advantage of this in some circuits, specifying circumstances where you are only to partially insert the plug. Once again, see Special Mackie Connections, on the next page. RCA PLUGS AND JACKS RCA “phono” plugs and jacks are often used in home stereo and video equipment and in many other applications (Figure 10). They are unbalanced, and electrically identical to a 1/4" TS phone plug or jack. Connect the signal to the center post and the ground or shield to the surrounding “basket.” There are no RCA jacks on the Mackie 8•Bus Series Mixing Consoles. Adapters to convert an RCA male plug to male 1/4” TS plug are available at any electronic shop, like Radio Shack. UNBALANCING A LINE In most studios, there is a mix of balanced and unbalanced inputs and outputs on the various pieces of equipment. This usually will not be a problem in making connections. • When connecting a balanced output to an unbalanced input, be sure the signal high connections at each end are wired together, and the balanced signal low goes to the ground connection at the unbalanced input. In most cases, the balanced ground will also be connected to the ground at the unbalanced input. If there are hum or radio frequency ground-loop problems, this connection may be left disconnected at the unbalanced end. • When connecting an unbalanced output to a balanced input, be sure that the signal high connections at each end are wired together. The unbalanced ground connection should be wired to the low and the ground connections of the balanced input. If there are ground-loop problems, try connecting the unbalanced ground connection only to the input low connection, and leaving the input ground connection disconnected. In some cases, you will have to make up special adapters to interconnect your equipment. For example, you may need a balanced XLR female connected to an unbalanced 1/4" TS phone plug. SPECIAL MACKIE CONNECTIONS The balanced-to-unbalanced connection has been anticipated in the wiring of the Mackie 8•Bus Series jacks. A 1/4" TS plug inserted into a 1/4" TRS balanced input, for example, will automatically unbalance the input and make all the right connections. Conversely, a 1/4” TRS plug inserted into a 1/4” unbalanced input will automatically tie the ring (low) to ground. TRS Send/Return Insert Jacks The Insert Jacks on both the 8•Bus input channels and on the Submaster and Main Mix buses are the three-conductor, TRS type 1/4" phone. They are unbalanced, but have both the mixer output (send) and the mixer input (return) signals in one connector (Figure 11 above). The sleeve is the common ground for both signals. The send from the mixer to the external unit is carried on the tip, and the return from the external unit to the mixer is on the ring. Using the Send Only on an Insert Jack If you insert a TS (mono) 1/4" plug only partially (to the first “click”) into an 8•Bus Series Insert Jack, the plug will not activate the jack switch and will not open the insert loop in the circuit. This allows you to borrow the channel or bus signal at that point in the circuit, without interrupting normal operation. Note: Do not overload or short-circuit the signal you are tapping from the mixer. That will affect the internal signal in the 8•Bus Series. 45 ADD-ONS SPECS ETC. Figure 12: “Y”cord (a.k.a MULT) for splitting signal (Plugis Makus Doublis). Note that all three plugs are the same — either TS (shown) or TRS. Don’t confuse this “off the shelf” connector with hybrid insert plugs as shown in Figure 11. Using the Return Only on Sub and Main Insert Jacks ADD-ONS SPECS ETC. If you insert a TS (mono) 1/4" plug only partially (to the first “click”) into an 8•Bus Series Submaster or Main insert jack, the plug will not activate the jack switch and will not open the insert loop in the circuit. This allows you to insert signal into the submaster or main at that point in the circuit. Note: Only unused buses can be used in this manner. Do not insert signal into a bus with signal on it, or unpredictable results may occur. MACKIE AUX RETURNS: Mono, Stereo, Whatever The Stereo AUX Returns are a fine example of the Mackie philosophy (which we just made up) of Maximum Flexibility with Minimum Headache. The returns will automatically be mono or stereo, depending upon what you plug into the Return Jacks. Here’s how it works: A mono return should be patched into the Return Jack labeled LEFT (MONO). The signal will be routed to both the left and right sides of the return circuit, and will show up in the center in any stereo pair of buses you assign it to. 46 A stereo return, having two return plugs, should be patched into the LEFT (MONO) and the RIGHT Return Jacks. A jack switch in the RIGHT Jack will disable the mono function, and the returns will show up in stereo. MULTS AND “Y”s A mult or “Y” connector allows you to route one output to two or more inputs by simply providing parallel wiring connections. You can make Ys and mults for both unbalanced and balanced circuits. See Figure 12 for an example. Remember: Only mult or “Y” an output into several inputs. If you need to combine several outputs into one input, you must use a mixer, not a mult or a “Y.” APPENDIX B: Options, Add-Ons and Extra Stuff OPTIONS Meter Bridge You can order an optional Mackie meter bridge for any 8•Bus Series console. The meter bridge extends across the width of the mixer and provides a 12-LED bar-graph meter (identical to the 8 submaster bus meters) for each channel strip. The meters can be globally switched, metering either the Tape Return signals to the mixer, posttape-in level switch (for watching multitrack source and tape levels) or the post-fader/postmute switch channel signals (handy for live sound mixing). The Mackie Sidecar The Sidecar provides eleven rack spaces for patchbays, the Mackie power supply, etc. At the back is a cable storage rack for organizing connection cords. Un-Cigarette Lighter An automobile-type cigarette lighter can be mounted on the front panel of your mixer, but NOT CONNECTED! What a joke for your smoking friends! Mixing Shoes The Mackie Kotoor Coallectshun of fine wearables includes our way-cool, lightweight Mixing Shoes. They’re designed for long hours and superior traction so that a little slip never ruins your mix. Insist that everyone in the control room wear Mackie Brand Mixing Shoes. They’re available in Rock, Soft Rock, Metal, Alternative, Country, Jazz, Gospel, Insufferable Audiophile and special spiked-steel-toe Producer/Client-Booters. ADD-ONS SPECS ETC. 47 APPENDIX C: Specifications 24•8 and 32•8 Specifications Because Mackie Designs is always trying to improve its products with new components and manufacturing methods, these specifications may change at any time.

SAVE THE SHIPPING BOX! Yes, we know it’s only slightly smaller than a doublewide mobile home, but you will need the entire carton and internal foam if your console ever needs service at some time in the future. If your kids make the box into a fort and cut holes in it — or if you stuff it in the dumpster of the fast-food place next door to your studio, we may have to sell and ship you another packing box later on. Don’t end up buying an empty box! Mackie mixing systems are notoriously bulletproof and reliable. But, hey…stuff happens. Any electronic product with as many parts as an 8•Bus console can occasionally have a minor casualty somewhere inside. And even if we could build our products to never break, there are those acts of nature that tend to visit consoles on occasion: spilled coffee, toppling monitors, etc. This section covers how to get your Mackie 8•Bus console healthy again. SERVICE Troubleshooting Intermittent signal problems. Faulty plugs and cables are often the culprits. A TRS plug can sit in a socket for months doing its job and then suddenly decide (based on the phase of the moon and barometric pressure) to short or stop conducting. If you’re having trouble with an individual channel, send or return, for gosh sakes swap cables before sending the board in for service. Check switch positions. Multi-bus consoles are pretty complicated. Switches like MIC/LINE, FLIP and EQ SPLIT can give the impression that something isn’t working right, if you’re not expecting them to be engaged. Finally, it doesn’t hurt to call our Technical Support Department at 800/258-6883 (8AM4:30PM Pacific time) to see if they have any ideas as to what might be wrong.
