Other Nuggets of Wisdom  
Read This Page!  
For optimum sonic performance, the channel faders  
and MAIN MIX faders should be set near the “U” (unity  
gain) markings.  
We realize that you must be dying to  
try out your new 1402-VLZ3. All we ask  
is that you read this page NOW, and the  
rest later — you’ll be glad you did.  
Always turn the MAIN MIX and CONTROL ROOM/  
SUBMIX faders down before making connections to and  
from your 1402-VLZ3.  
WARNING: Before you plug the AC power  
cord into the mixer, make sure the VOLTAGE  
SELECTOR switch is set to the same voltage  
as your local AC mains supply (see page 12).  
If you shut down your equipment, turn off your ampli-  
fier first. When powering up, turn on your amplifier last.  
Save the shipping box! You may need it someday.  
Level-Setting Procedure  
Instant Mixing  
Message to seasoned pros: do not set levels using the  
old “Turn the GAIN up until the clip light comes on,  
then back off a hair” trick. When a Mackie mixer clip  
light comes on, you really are about to clip. We worked  
and slaved to come up with a better system, one that  
provides low noise and high headroom.  
Here’s how to get going right away, assuming you have  
a microphone and a keyboard:  
1. Plug your microphone into channel 1’s MIC  
input.  
2. Turn on the 1402-VLZ3.  
Adjusting input levels (Chs. 1–6 only)  
3. Perform the Level-Setting Procedure.  
On the first six channels, it’s not even necessary to  
hear what you’re doing to set optimal levels. But if you’d  
like to: Plug headphones into the PHONES jack, then  
move the CONTROL ROOM/SUBMIX fader up a little.  
4. Connect cords from the MAIN OUTS (XLR, 1⁄4"  
or RCA, your choice) to your amplifier.  
5. Hook up speakers to the amp and turn it on.  
6. Turn up the 1402-VLZ3’s channel 1 fader to the  
U mark, and the MAIN MIX fader one quarter of  
the way up.  
The following steps must be performed one channel at  
a time:  
1. Turn the GAIN, AUX SEND knobs and FADERS  
fully down.  
7. Sing like a canary!  
8. Plug your keyboard into stereo channel 7-8.  
9. Turn that channel’s fader to the U mark.  
2. Set the EQ knobs at the center detent.  
3. Connect the signal source to the input.  
4. Engage (push in) the channel's SOLO switch.  
10. Play like a madman and sing like a canary!  
It’s your first mix!  
5. Engage the AFL/PFL switch in the master sec-  
tion. A green LEVEL SET light will turn on.  
6. Play something into the selected input. This  
could be an instrument, a singing or speaking  
voice, or a line input such as a CD player or  
tape recorder output. Be sure that the volume  
of the input is the same as it would be during  
normal use. If it isn’t, you may have to readjust  
these levels during the middle of the set.  
Please write your serial number here for future  
reference (i.e., insurance claims, tech support,  
return authorization, make dad proud, etc.)  
7. Adjust the channel’s GAIN control so that the  
display on the LED meters stays around “0” and  
never goes higher than “+7.”  
Purchased at:  
8. If you apply some EQ, repeat step 7.  
9. Disengage that channel’s SOLO switch.  
10. Repeat for channels 1 through 6.

Introduction  
Thank you for choosing a Mackie professional com-  
pact mixer. The 1402-VLZ3 is equipped with our pre-  
cision-engineered XDRTM Extended Dynamic Range  
premium studio-grade mic preamp.  
This icon marks information that is critically  
important or unique to the 1402-VLZ3. For your  
own good, read them and remember them. They  
will be on the final test.  
Now that you have your 1402-VLZ3, find out how to get  
the most from it. That’s where this manual comes in.  
This icon will lead you to in-depth explana-  
tions of features and practical tips. While not  
mandatory, they usually have some valuable  
nuggets of information.  
How To Use This Manual  
Since many of you folks will want to hook up your  
1402-VLZ3 immediately, the first pages you will en-  
counter after the table of contents are the ever-popular  
hookup diagrams. These show typical mixer setups for  
Recording and Stereo PA.  
Appendix A is a section on troubleshooting and repair  
information.  
Appendix B is a section on connectors: XLR connec-  
tors, TRS balanced connectors, TS unbalanced connec-  
tors, and Insert connectors.  
After this section is a detailed tour of the entire mixer.  
Every feature of the 1402-VLZ3 is described “geographi-  
cally;” in other words, in order of where it is physically  
placed on the mixer’s top or rear panel. These descrip-  
tions are divided into the first three sections, just as  
your mixer is organized into three distinct zones:  
Appendix C shows the technical specifications, and  
a block diagram showing the internal signal path and  
general goings-on within the mixer.  
Appendix D was removed after it became bloated and  
painful.  
Patchbay: The patchbay along the top and back,  
where you connect things.  
Channel Strip: The eight channel strips on the left  
where you adjust each channel.  
Output Section: The output section on the right.  
Throughout these sections you’ll find illustrations,  
with each feature numbered. If you’re curious about a  
feature, simply locate it on the appropriate illustration,  
notice the number attached to it, and find that number  
in the nearby paragraphs.

At the risk of stating the obvious, this is where you  
plug everything in: microphones, line-level instruments  
and effects, headphones, and the ultimate destination  
for your sound: a tape recorder, PA system, etc.  
be “unseen” by dynamic mics (Shure SM57/SM58, for  
instance), which don’t need external power and aren’t  
affected by it anyway.  
The 1402-VLZ3’s phantom power is globally controlled  
by the PHANTOM switch on the rear panel. (This means  
See Appendix B for further details and drawings of  
the connectors you can use with the 1402-VLZ3. Also see the phantom power for channels 1-6 is turned on and off  
the Channel Strip description on page 13 for details of  
the signal routing from the XLR and Line inputs.  
together.)  
Never plug single-ended (unbalanced)  
microphones or instruments into the MIC  
input jacks if the PHANTOM power is on.  
1. MIC INPUTS (Channels 1–6)  
We use phantom-powered, balanced microphone  
inputs just like the big studio mega-consoles, for exactly  
the same reason: This kind of circuit is excellent at re-  
jecting hum and noise. You can plug in almost any kind  
of mic that has a standard XLR male mic connector.  
Do not plug instrument outputs into the  
MIC input jacks with PHANTOM power on  
unless you know for certain it is safe to do so.  
2. LINE INPUTS (Channels 1–6)  
Professional ribbon, dynamic, and condenser mics  
will all sound excellent through these inputs. The  
1402-VLZ3’s mic inputs will handle any kind of mic level  
you can toss at them, without overloading. Be sure to  
perform the Level-Setting Procedure on page 3.  
These six line inputs share circuitry (but not phan-  
tom power) with the mic preamps, and can be driven  
by balanced or unbalanced sources at almost any level.  
You can use these inputs for virtually any signal you’ll  
come across, from instrument levels as low as –40 dB to  
operating levels of –10 dBV to +4 dBu, since there is 40  
dB more gain available than on channels 7–14.  
Not every instrument is made to connect directly to a  
mixer. Guitars commonly need a Direct Injection (DI)  
box to connect to the mixer's MIC inputs. These boxes  
convert unbalanced line-level signals from your guitar,  
into balanced mic-level outputs, and provide signal and  
impedance matching. They also let you send your gifted  
guitar renditions over long cables or audio snakes, with  
minimum interference and high-frequency signal loss.  
Ask your dealer or guitar maker about their recommen-  
dations for a good DI box.  
To connect balanced lines to these inputs, use a 1⁄4"  
Tip-Ring-Sleeve (TRS) plug, the type found on stereo  
headphones.  
To connect unbalanced lines to these inputs, use a  
1⁄4" mono (TS) phone plug or standard instrument  
cable.  
LINE IN inputs 1–6 are a good place to connect older  
instruments that need more gain. You can correct weak  
levels by adjusting the corresponding channel’s GAIN  
control.  
PHANTOM POWER  
Most modern professional condenser mics are  
equipped for Phantom Power, which lets the mixer  
send low-current DC voltage to the mic’s electronics  
through the same wires that carry audio. (Semi-pro  
condenser mics often have batteries to accomplish the  
same thing.) “Phantom” owes its name to an ability to

3. LOW CUT (Channels 1–6)  
5. STEREO LINE INPUTS  
(Channels 7–8, 9–10, 11–12 and 13–14)  
Each LOW CUT switch, often referred to as a High  
Pass Filter (all depends on how you look at it), cuts bass  
frequencies below 75 Hz at a rate of 18 dB per octave.  
These fully balanced inputs are designed for stereo or  
mono, balanced or unbalanced signals, from –10 dBV to  
+4 dBu. They can be used with just about any profes-  
sional or semi-pro instrument, effect or tape player.  
We recommend that you use LOW CUT on every  
microphone application except kick drum, bass guitar,  
bassy synth patches, or recordings of earthquakes.  
These aside, there isn’t much down there that you want  
to hear, and filtering it out makes the low stuff you do  
In the stereo audio world, an odd-numbered chan-  
nel usually receives the “left signal.” For example, you  
would feed the 1402-VLZ3’s line inputs 7-8 a stereo  
want much more crisp and tasty. Not only that, but LOW signal by inserting the device’s left output plug into the  
CUT can help reduce the possibility of feedback in live  
situations and it helps to conserve the amplifier power.  
channel 7 jack, and its right output plug into the chan-  
nel 8 jack.  
Another way to consider LOW CUT’s function is that it  
actually adds flexibility during live performances. With  
When connecting a mono device (just one cord), al-  
ways use the LEFT (MONO) input (jacks 7, 9, 11, or 13)

ization on vocals. Many times, bass shelving EQ can  
really benefit voices. Trouble is, adding LOW EQ also  
boosts stage rumble, mic handling clunks and breath  
pops. LOW CUT removes all those problems so you can  
add low EQ without losing a woofer.  
or 14)— this way the signal will appear on both sides.  
This trick is called “jack normalling.”  
6. +4/–10 LEVEL (Stereo Channels only)  
This switch adjusts the input sensitivity of the line  
inputs on channels 7 to 14. If the sound source is a "–10"  
device, engage this switch. If you are unsure, leave the  
switch up, and perform the Level Setting Procedure,  
substituting this switch for the GAIN knob to find the  
best position for it.

“Serial” means that the entire signal is routed through  
the effects device. Examples: compressor/limiters,  
graphic equalizers. Line-level sources can be patched  
through a serial effects device before or after the mixer,  
or preferably through the insert jacks located on the  
rear panel (CHANNEL INSERT [17] send/return).  
4. GAIN (Channels 1–6)  
If you haven’t already, please read the Level-Setting  
Procedure.  
GAIN adjusts the input sensitivity of the mic and line  
inputs connected to channels 1 through 6. This allows  
signals from the outside world to be adjusted to optimal  
internal operating levels.

If the signal originates through the

“Parallel” means that a portion of the signal in the  
mixer is tapped off to the device (AUX SEND), pro-  
cessed and returned to the mixer (STEREO RETURN)  
to be mixed with the original “dry” signal. This way,  
multiple channels can all make use of the same effects  
device. Examples: reverb, digital delay.

This 15 dB of attenuation can be very handy when you

a lot of EQ gain, or both. Without this “virtual pad,” this  
scenario might lead to channel clipping.

Use these jacks for convenient tape playback of your  
mixes. You’ll be able to review a mix, then rewind and  
try another pass, without repatching or disturbing the  
mixer levels. You can also use these with a tape or CD  
player to feed music to a PA system between sets.  
7. STEREO RETURNS  
This is where you connect the outputs of your par-  
allel effects devices (or extra audio sources). These  
balanced inputs are similar to the stereo LINE IN [2]  
inputs (without EQ, Aux Sends, Pan, Mute, and Solo).  
The circuits will handle stereo or mono, balanced or  
unbalanced signals, either instrument level, –10 dBV  
or +4 dBu. They can be used with just about any pro or  
semipro effects device on the market. The signals com-  
ing into these inputs can be adjusted using the STEREO  
RETURN [41] knobs before passing onto the main mix  
bus (see page 18).  
WARNING: Engaging both the TAPE and  
ASSIGN TO MAIN MIX buttons in the CON-  
TROL ROOM SOURCE [33] matrix can create  
a feedback path between TAPE INPUT and TAPE OUT-  
PUT. Make sure your tape deck is not in record, record-  
pause, or input monitor mode when you engage these  
switches, or make sure the CONTROL ROOM / SUBMIX  
fader [34] is fully down (off).  
One Device: If you have just one parallel effects de-  
vice (two cords), use STEREO RETURN 1 left and right,  
and leave RETURN 2 unplugged. That way, the unused  
RETURN 2 level control can be used to feed RETURN 1  
to your stage monitors, via the RETURN TO AUX 1 [42]  
switch.  
10. TAPE OUTPUT  
These unbalanced RCA connections tap the main  
mix output to make simultaneous recording and PA  
work more convenient. Connect these to your recorder’s  
inputs. (See also MAIN MIX [32] on page 16.)  
Mono Device: If you have an effects device with  
a mono output (one cord), plug that into STEREO  
RETURN 1 left/mono, and leave the right unplugged.  
The signal will be sent to both sides, magically appear-  
ing in the center as a mono signal. This won’t work with  
STEREO RETURN 2 — you’ll need a Y-cord.  
Mono Out: If you want to feed a mono signal to your  
tape deck or other device, simply use an RCA Y-cord to  
combine these outputs. Do not attempt this with any  
other outputs on the 1402-VLZ3.

11. ⁄4" MAIN OUTS  
8. AUX SEND 1&2  
These outputs feed the main mix out into the waiting  
world. You can feed your amplifiers this way, or through  
the XLR MAIN OUTS [13].  
The AUX SEND [31] knobs in the channel sections  
tap a portion of each channel's signal to provide an out-  
put here to feed external parallel effects processors or  
stage monitoring. See the AUX SEND details on page 15.  
These balanced outputs are capable of delivering 22  
dBu into a 600 ohm balanced or unbalanced load.  
These 1⁄4" jacks are also balanced outputs capable  
of delivering 22 dBu into a 600 ohm balanced or unbal-  
anced load.  
To use these outputs to drive balanced inputs, con-  
nect 1⁄4" TRS (Tip–Ring–Sleeve) phone plugs like this:  
Tip = + (hot)  
9. TAPE INPUT  
Ring = –(cold)  
Sleeve = Ground  
These RCA jacks are designed to work with semipro  
as well as pro recorders. To compensate for typically  
low levels, signals coming in here will be automatically  
boosted by 6 dB.  
For most music recording and PA applications,  
unbalanced lines are perfectly acceptable. To use these  
outputs to drive unbalanced inputs, connect 1⁄4" TS  
(Tip-Sleeve) phone plugs like this:  
Connect your tape recorder’s outputs here, using good  
quality hi-fi (RCA) cables.

12. PHONES  
This stereo jack will drive any standard headphone  
to very loud levels. Walkperson-type phones can also be  
used with an appropriate adapter. To learn how signals  
are routed to these outputs, see SOURCE MATRIX  
[33] on page 16. If you’re wiring your own cable for the  
PHONES output, follow standard conventions:  
These 1⁄4" jacks are balanced outputs capable of de-  
livering 22 dBu into a 600 ohm balanced or unbalanced  
load.

the MUTE/ALT 3-4 [25] switch pressed in (see page 13  
for the tender details).

levels may be painfully loud with some earphones. BE  
CAREFUL! Always move the CTL ROOM/ SUBMIX fader  
all the way down before connecting headphones. Keep  
it down until you’ve put the phones on. Then turn it up  
slowly. Why? “Engineers who fry their ears find them-  
selves with short careers.”  
17. CHANNEL INSERT (Channels 1–6 )  
These rear-panel jacks are where you connect serial  
effects such as compressors, equalizers, de-essers, or  
filters. Since most people don’t have more than a few of  
these gadgets, we’ve included inserts for just the first  
six channels. If you want to use this kind of processing  
on channels 7 through 14, simply patch through the  
processor before you plug into the 1402-VLZ3.  
13. XLR MAIN OUTS  
These line-level outputs connect the main mix to the  
outside world. Connect them to the balanced inputs of  
a power amplifier or powered speakers. See page 16 for  
details of the main mix.  
The channel insert points are after the GAIN [4] and  
LOW CUT [3] controls, but before the channel’s EQ  
[27] controls and FADER [23]. The send (tip) is low-  
impedance (120 ohms), capable of driving any line-level  
device. The return (ring) is high-impedance (over 2.5 k  
ohms) and can be driven by almost any device.  
These low-impedance outputs are fully balanced  
and capable of driving +4 dBu lines with up to 28 dB  
of headroom. This output is 6 dB hotter than other  
outputs.

Engaging this switch reduces the level of the bal-

microphone input of, say, another mixer. (You can safely  
connect the XLR outputs into an input that provides 48V  
phantom power.)  
See Appendix B for details and drawings about Insert  
cables, and a diagram showing three ways to use the  
jacks.  
Besides being used for inserting external devices,  
these jacks can also be used as channel direct outputs;  
post-GAIN, post-LOW CUT, and pre EQ. In fact, Mackie  
mic preamps have become so famous, that people buy  
these mixers just to have six of these in their arsenal.  
15. CONTROL ROOM

thing other than the main mix. The source is selected

18. POWER CONNECTION  
21. POWER SWITCH  
Just in case you lose the cord provided with the 1402-  
VLZ3, its power jack accepts a standard 3-prong IEC  
cord like those found on most professional recorders,  
musical instruments, and computers.  
Press the top of this rocker switch inwards to turn on  
the mixer. The power LED on the top surface of the mix-  
er will glow with happiness, or at least it will if you have  
the mixer plugged in to a suitable live AC mains supply.  
WARNING: Before you plug the AC power  
cord into the 1402-VLZ3, you must make sure  
that the VOLTAGE SELECTOR [20] slide  
switch is set to the same voltage as your local AC mains  
supply.  
Press the bottom of this switch to turn off the mixer,  
whenever you feel that this would be a safe thing to do.

and turn it off last. This will reduce the possibilities of  
any turn-on, or turn-off thumps in your speakers.  
19. FUSE  
22. PHANTOM SWITCH  
The 1402-VLZ3 is fused for your (and its own) protec-  
tion. If you suspect a blown fuse, disconnect the cord,  
pull the fuse drawer out (located just below the cord  
receptacle) and replace the fuse with a 500 mA (0.5  
amps) SLO BLO 5x20 mm, available at electronics  
stores or your dealer. If your local voltage is 220-240  
VAC, use a 250 mA fuse.  
This global rocker switch controls the phantom power  
supply for condenser microphones plugged into channel  
MIC [1] inputs (see page 8).  
Press the top of the switch inwards to engage phan-  
tom power to the six MIC inputs. Press the bottom of  
the switch to turn it off.  
If two fuses blow in a row, something is very wrong.  
Please call our toll-free number 1-800-898-3211 from  
within the U.S. (or call the distributor in your country)  
and find out what to do.  
When turned on (or off), the phantom power circuitry  
takes a few moments for voltage to ramp up (or down).  
This is perfectly normal.  
20. VOLTAGE SELECTOR  
WARNING: Before you plug the AC power  
cord into the 1402-VLZ3, you must make sure  
that this slide switch is set to the same volt-  
age as your local AC main supply. Only slide the voltage  
switch with the power cord unplugged.  
Use a small flat-headed screwdriver to slide the switch  
if needed. The switch allows you to use the mixer in dif-  
ferent countries and voltages, meet interesting people  
from other cultures, and entertain them with your  
unique blend of Rockabilly Funkadelia Thrash Metal.

cally. The only difference is that the six on the left are  
for individual mics or mono instruments, and have more which mode you'll be hearing. With the switch up, you'll  
The 1402-VLZ3 has "dual-mode solo." The SOLO  
MODE [35] switch in the Master section determines  
gain available, while the next four are for either stereo  
or mono line-level sources. (Each of the stereo channel  
get "AFL" (After-Fader-Listen), which is post-FADER,  
post-PAN, making it ideal for mixdown soloing. With the  
strips is actually two complete circuits. The controls are switch down, you're in "PFL" (Pre-Fader-Listen), used  
linked together to preserve stereo.) We’ll start at the  
bottom and work our way up…  
in the Level Setting Procedure.  
Soloed channels are sent to the SOURCE mix, which  
ultimately feeds your control room, phones and meters.  
Whenever SOLO is engaged, all SOURCE selections  
(MAIN MIX, ALT 3-4 and TAPE) are defeated, to allow  
the soloed signal to do just that — solo!  
“U” LIKE UNITY GAIN  
Mackie mixers have a “U” symbol on almost every  
level control. This “U” stands for “unity gain,” meaning  
no change in signal level. Once you have adjusted the  
input signal to line-level, you can set every control at  
“U” and your signals will travel through the mixer at  
optimal levels. What’s more, all the labels on our level  
controls are measured in decibels (dB), so you’ll know  
what you’re doing level-wise if you choose to change a  
control’s settings.  
25. MUTE/ALT 3–4  
The dual-purpose MUTE/ALT 3–4 bus is a Mackie sig-  
nature. When Greg was designing our first product, he  
had to include a MUTE switch for each channel. MUTE  
switches do just what they sound like they do. They turn  
off the signal by “routing” it into oblivion. “Gee, what a  
waste,” Greg reasoned. “Why not have the mute button

To use this as a MUTE switch, all you have to do is

the channel.

These faders control the channel’s

When doing multitrack recording, use the ALT 3–4  
outputs to feed your multitrack. With most decks, you  
can mult the ALT 3–4 outputs, using Y-cords or mults, to  
feed multiple tracks. So, take ALT OUTPUT L and send  
it to tracks 1, 3, 5 and 7, and ALT OUTPUT R and send it  
to tracks 2, 4, 6 and 8. Now, tracks that are in Record or  
Input modes will hear the ALT 3–4 signals, and tracks in  
Playback or Safe modes will ignore them.

When doing live sound or mixdown, it’s often handy

That’s called subgrouping. Simply assign these channels  
to the ALT 3–4 mix, engage ALT 3–4 in the SOURCE  
[33] matrix, and the signals will appear in the control  
room and headphones. If you want the ALT 3–4 signals  
to go back into the main mix, engage the ASSIGN TO  
MAIN MIX [37] switch, and the CONTROL ROOM/  
SUBMIX fader [34] controls the levels of all channels  
assigned to ALT 3–4.

Another way to do the same thing is assign the chan-  
nels to the ALT 3–4 mix, then patch out of the ALT  
OUTPUT L and R back into an unused stereo channel  
(7–8, 9–10, 11–12, 13–14). If that’s your choice, don’t  
ever engage the MUTE/ALT 3–4 switch on that stereo  
channel, or you’ll have every dog in the neighborhood  
howling at your feedback loop.  
CONSTANT LOUDNESS ! ! !  
The 1402-VLZ3’s PAN controls employ a design called  
“Constant Loudness.” It has nothing to do with living  
next to a freeway. As you turn the PAN knob from left  
to right (thereby causing the sound to move from the  
left to the center to the right), the sound will appear to  
remain at the same volume (or loudness).  
Another benefit of the ALT 3–4 feature is that it  
can act as a “AFL” (After-Fader-Listen): just engage a  
channel's MUTE/ALT 3–4 switch and the ALT 3–4 switch  
in the SOURCE matrix and you’ll get that channel, all by  
itself, in the control room and phones.  
If you have a channel panned hard left (or right) and  
reading 0 dB, it must dip down about 4 dB on the left  
(or right) when panned center. To do otherwise (the  
way Brand X compact mixers do) would make the sound  
appear much louder when panned center.  
MUTE/ALT 3–4 is one of those controls that can bewil-  
der newcomers, so take your time and play around with  
it. Once you’ve got it down, you’ll probably think of a  
hundred spiffy uses for it!  
3-BAND EQ  
The 1402-VLZ3 has 3-band equalization at carefully  
selected points — LOW shelving at 80 Hz, MID peaking  
at 2.5 kHz, and HI shelving at 12 kHz. “Shelving” means  
that the circuitry boosts or cuts all frequencies past the  
specified frequency. For example, rotating the LOW EQ  
knob 15 dB to the right boosts bass starting at 80 Hz and  
continuing down to the lowest note you never heard.  
“Peaking” means that certain frequencies form a “hill”  
around the center frequency — 2.5 kHz in the case of  
the MID EQ.  
26. PAN  
AUX  
U
PAN adjusts the amount of chan-  
nel signal sent to the left versus the  
31  
right outputs. On mono channels  
(ch. 1–6 or 7–14 with connections  
to the left input only) these controls  
act as pan pots. On stereo channels  
(7–14) with stereo connections to  
L and R inputs, the PAN knob works  
like the balance control on your  
home stereo.

Each AUX send level ranges from off through unity  
(the center detent position) on up to 15 dB of extra gain  
(when turned fully clockwise). Chances are you’ll never  
need this extra gain, but it’s nice to know it’s there if  
you do.

We recommend going into a stereo reverb in mono and  
returning in stereo. We have found that on most “stereo”  
reverbs the second input just ties up an extra AUX send  
and adds nothing to the sound. There are exceptions, so  
feel free to try it both ways. If your effects device is true  
stereo all the way through, use AUX 1 to feed its left  
input and AUX 2 to feed the right input.  
MODERATION DURING EQ  
With EQ, you can also screw things up royally. We’ve  
designed a lot of boost and cut into each equalizer cir-  
cuit, because we know everyone will occasionally need  
that. But if you max the EQs on every channel, you’ll  
get mix mush. Equalize subtly and use the left sides of  
the knobs (cut), as well as the right (boost). Very few  
gold-record-album engineers ever use more than about  
3dB of EQ. If you need more than that, there’s usually a  
better way to get it, such as placing a mic differently (or  
using a different kind of mic entirely).  
Still with us? Good for you. Here come the tricky  
parts, the output, or master section where the mixing  
is really done. We have even started it on a shiny new  
page:  
31. AUX 1 and 30. AUX 2 SEND  
These knobs allow you to tap a portion of each chan-  
nel signal out to another source for parallel effects  
processing or stage monitoring. AUX send levels are  
controlled by the channel’s AUX 1 and AUX 2 knobs and  
by the AUX 1 MASTER [40].  
These are more than just effects and monitor sends.  
They can be used to generate separate mixes for record-  
ing or “mix-minuses” for broadcast. By using AUX 1 in  
the PRE [39] mode, these mix levels can be obtained  
independently of the channel’s fader.  
AUX 1 (when in post mode) and AUX 2, are post-LOW  
CUT, post-EQ and post-fader. That is, the sends obey the  
settings of these controls. AUX 1 in PRE mode follows  
the EQ and LOW CUT settings only. PAN and LEVEL  
(FADER) have no effect on the PRE send (see diagram  
below).

33. CONTROL ROOM SOURCE MATRIX  
Typically, the engineer sends the main mix to an audi-  
ence (if mixing live) or a mixdown deck (if recording).  
But what if the engineer needs to hear something other  
than the main mix? With the 1402-VLZ3, the engineer  
has several choices of what to listen to. This is one of  
those tricky parts, so buckle up.

Via these SOURCE switches, you can choose to listen  
to any combination of main mix, ALT 3-4 and TAPE. By  
now, you probably know what the main mix is. ALT 3-4 is  
that additional stereo mix bus. Tape is the stereo signal  
coming in from the TAPE INPUT [9] jacks.

34. CONTROL ROOM/SUBMIX

This fader controls the levels of both the control room  
outputs and phones outputs. The fader ranges from off,  
through unity gain at the "U", to 10 dB of extra gain  
when fully up.  
When MAIN MIX is your control room source selec-  
tion, those signals will now pass through two level con-  
trols on the way to your control room amp and phones  
— the MAIN MIX [32] faders and this CONTROL ROOM  
/ SUBMIX fader. This way, you can send a nice healthy  
level to the main output (MAIN MIX fader at “U”), and  
a quiet level to the control room or phones (CONTROL  
ROOM / SUBMIX fader wherever you like it).  
32. MAIN MIX FADERS  
These faders control the levels of signals sent to the  
main outputs: XLR [13], 1⁄4" TRS [11], and TAPE [10].  
All channels and STEREO RETURNS that are not muted  
or turned fully down will end up in the main mix.  
Fully down is off, the "U" is unity gain, and fully up  
provides 10 dB additional gain. This additional gain will  
typically never be needed, but once again, it’s nice to  
know it’s there. This is the fader to move down at the  
end of the song when you want The Great Fade-Out.  
When ALT 3-4 or TAPE is selected, or SOLO is en-  
gaged, this fader will be the only one controlling these  
levels (channel controls not withstanding).

Whatever your selection, you can also use the control  
room outputs for other applications. Its sound quality is  
just as impeccable as the main outputs. It can be used  
as additional main mix output, which may sound silly  
since there are already three, but this one has its own  
level control. However, should you do something like  
this, be sure that you do not engage a SOLO switch, as  
that will interrupt your SOURCE selection.  
37. ASSIGN TO MAIN MIX  
Let’s say you’re doing a live show. Intermission is near-  
ing and you’ll want to play a soothing CD for the crowd  
to prevent them from becoming antsy. Then you think,  
“But I have the CD player plugged into the TAPE inputs,  
and that never gets to the main outputs!” Oh, but it  
does. Simply engage this switch and your SOURCE [33]  
matrix selection, after going through the CONTROL  
ROOM / SUBMIX [34] fader, will feed into the main mix,  
just as if it were another stereo channel.  
35. SOLO MODE (AFL/PFL)  
Engaging a channel’s SOLO [24] switch will cause  
this dramatic turn of events: Any existing SOURCE [33]  
matrix selections will be replaced by the SOLO signal,  
appearing at the control room outputs, phones outputs,  
and meter. The audible SOLO levels are then controlled  
by the CONTROL ROOM / SUBMIX [34] fader. The  
SOLO levels appearing on the right meter display are  
not controlled by anything — you wouldn’t want that.  
You want to see the actual channel level on the meter  
display regardless of how loud you’re listening.  
Another handy use for this switch is to enable the ALT  
3-4 mix to become a submix of the main mix, using the  
CONTROL ROOM/SUBMIX fader as its level control.  
Side effects: (1) Engaging this switch will also feed  
any soloed channels into the main mix, which may be  
the last thing you want. (2) If you have MAIN MIX as  
your SOURCE matrix selection and then engage ASSIGN  
TO MAIN MIX [37], the main mix lines to the SOURCE  
matrix will be interrupted to prevent feedback. Then  
again, why on earth would anyone want to assign the  
main mix to the main mix?  
With this SOLO MODE switch in the up position,  
you're in AFL mode, meaning After-Fader-Listen. You'll  
hear the output of the soloed channel and it will follow  
the GAIN, EQ, FADER and PAN settings. It's similar to  
muting all the other channels, but without the hassle.  
Use AFL mode during mixdown.  
38. METERS – MANY DISPLAYS IN ONE!  
The 1402-VLZ3’s peak metering system is made up of  
two columns of twelve LEDs. Deceptively simple, consid-  
ering the multitude of signals that can be monitored by  
it.  
With the SOLO MODE switch in the down position,  
you're in PFL mode, meaning Pre-Fader-Listen (post  
EQ). This is required for the Level Setting Procedure,  
and is handy for quick spot-checks of channels, espe-  
cially ones that have their faders turned down.  
If nothing is selected in the SOURCE [33] matrix and  
no channels are in SOLO [24], the meters will just sit  
there and do nothing. To put them to work, you must  
make a selection in the SOURCE matrix (or engage a  
SOLO switch).  
In either mode, SOLO will not be affected by a  
channel's MUTE/ALT [25] switch position.  
Why? You want the meter display to reflect what the  
engineer is listening to, and as we’ve covered, the engi-  
neer is listening either to the control room outputs or  
the phones outputs. The only difference is that while the  
listening levels are controlled by the CONTROL ROOM  
/ SUBMIX [34] fader, the meters read the SOURCE mix  
before that control, giving you the real facts at all times,  
even if you’re not listening at all.  
36. RUDE SOLO LIGHT  
This flashing Light Emitting Diode serves two pur-  
poses — to remind you that at least one channel is  
in SOLO, and to let you know that you’re mixing on a  
Mackie. No other company is so concerned about your  
level of SOLO awareness. If you work on a mixer that  
has a solo function with no indicator lights, and you  
happen to forget you’re in solo, you can easily be tricked  
into thinking that something is wrong with your mixer.  
Hence the RUDE SOLO LIGHT. It’s especially handy at  
Thanks to the 1402-VLZ3’s wide dynamic range,  
you can get a good mix with peaks flashing anywhere  
between –20 and +10 dB on the meters. Most ampli-

forgiving either. For best real-world results, try to keep  
your peaks between “0” and “+7”.  
You may already be an expert at the world of “+4” (+4  
dBu=1.23 V) and “–10” (–10 dBV=0.32 V) operating  
levels. Basically, what makes a mixer one or the other  
is the relative 0 dB VU (or 0 VU) chosen for the meters.  
A “+4” mixer, with a +4 dBu signal pouring out the back  
will actually read 0 VU on its meters. A “–10” mixer,  
with a –10 dBV signal trickling out, will read 0 VU on its  
meters. So when is 0 VU actually 0 dBu? Right now!

39. PRE/POST (AUX 1)  
Besides being used to work effects into your mix, Aux  
Sends serve another critical role — that of delivering  
cue mixes to stage monitors, so musicians can hear what  
they’re doing. On the 1402-VLZ3, AUX SEND 1 can play  
either role, depending on the position of this switch.  
A WORD ABOUT AUX  
Sends are outputs, Returns are inputs. The AUX [30]  
and [31] knobs tap the signal off the channel and sends  
it to the AUX SEND [8] outputs. The AUX 1 signal is  
sent to the AUX 1 MASTER [40] knob before going  
to the AUX SEND 1 output and the AUX 2 signal goes  
directly to the AUX SEND 2 output.  
With the AUX 1 SELECT switch up (disengaged),  
AUX SEND 1 will tap a channel pre-fader [23] and pre-  
MUTE/ALT 3-4 [25], meaning that no matter how you  
manipulate those controls as they feed the main mix,  
the AUX SEND will continue to belt out that channel’s  
signal. This is the preferred method for setting up stage  
monitor feeds. EQ settings will affect all AUX SENDs.  
These outputs can be fed to the inputs of a reverb or  
other device. From there, the outputs of this external  
device are fed back to the mixer’s STEREO RETURN [7]  
jacks. Then these signals are sent through the STEREO  
With the switch down, the AUX SEND 1 becomes an  
RETURN [41] level controls, and are finally delivered to ordinary effects send — post-fader and post-MUTE/ALT  
the main mix.  
3-4. This is a must for effects sends, since you want the  
levels of your “wet” signals to follow the “dry” level.  
40. AUX 1 MASTER  
U

The AUX 1 MASTER provides overall level control of  
AUX SEND 1, just before it’s delivered to the AUX SEND  
1 [8] output. (AUX SEND 2 has no such control.) This  
knob goes from off (turned fully down), to unity gain at  
the center detent, with 10 dB of extra gain (turned fully  
up). As with some other level controls, you may never  
need the additional gain, but if you ever do, you’ll be  
glad you bought a Mackie.

Signals passing through these STEREO RETURN level  
controls will proceed directly to main mix, with one ex-  
ception (see next paragraph). The STEREO RETURNs  
do not have MUTE/ALT 3-4 switches, so if you want  
these signals to get to the ALT 3-4 mix, you’ll have to  
patch the effects device’s outputs into one of the stereo  
channels, and MUTE/ALT [25] those channels.  
42. RETURN TO AUX 1  
If you want to add reverb or delay to the stage monitor  
mixes, this is the switch for you. The implementation  
leading up to the switch is the tricky part:  
With the switch up, STEREO RETURN 1 and 2 behave  
normally — they deliver their signals into the main mix.  
With the switch down, STEREO RETURN 1 still behaves  
normally, but STEREO RETURN 2 will feed AUX SEND 1  
instead of the main mix.  
Still with us? Good. So far, with the switch down, we  
have STEREO RETURN 1 feeding the main mix and  
STEREO RETURN 2 feeding AUX SEND 1. Now, suppose  
you only have one effects device, and you want it to feed  
both the main mix and AUX SEND 1. That’s where “jack  
normalling” comes in:  
JACK NORMALLING  
Jack normalling (not to be confused with Jack  
Normalling, Chicago Cubs utility infielder, 1952-61, .267  
LBA) is a feature found on almost every mixer, keyboard  
and effects device. These jacks have special spring-  
loaded pins that connect to the signal pins, but when  
something is plugged into the jack, that connection is  
broken.  
These normalling pins can be used in all sorts of ways.  
The ubiquitous phrase “LEFT (MONO)” means that if  
you plug a signal into the LEFT side and have nothing in  
the RIGHT side, that signal is also fed to the right input,  
courtesy of jack normalling. As soon as you plug some-  
thing in the RIGHT side, that normalled connection is  
broken.  
How does all this relate to the RETURN TO AUX 1  
switch? STEREO RETURN 1’s inputs are normalled to  
STEREO RETURN 2. If you have one effects device, plug  
it into STEREO RETURN 1. Plug nothing into STEREO  
RETURN 2. Now the signals feeding the STEREO RE-  
TURN 1 inputs will also be sent to the STEREO RETURN  
2 inputs.  
Engage the RETURN TO AUX 1 switch, and now the  
STEREO RETURN 2 knob will become an additional  
AUX SEND 1 knob for the signal at STEREO RETURN 1.  
Say that ten times! Once again, STEREO RETURN 1 will  
behave normally, as always.  
Congratulations! You’ve just read about all the fea-  
tures of your 1402-VLZ3. You’re probably ready for a cold  
one. Go ahead. The rest of the manual can wait.

PST, to explain the problem and request a Service  
Request Number. Have your serial number ready.  
You must have an Service Request Number before  
you can obtain warranty service.  
Troubleshooting  
Bad Channel  
3. Keep this owner’s manual and the detachable line-  
cord. We don’t need them to repair the unit.  
Is the MUTE/ALT 3–4 switch in the correct  
position?  
4. Pack the unit in its original package, including end-  
caps and box. This is VERY IMPORTANT. Mackie is  
not responsible for any damage that occurs due to  
non-factory packaging.  
Is the fader turned up?  
Try unplugging any INSERT devices (Channels  
1–6 only).  
5. Include a legible note stating your name, shipping  
address (no P.O. boxes), daytime phone number,  
Service Request Number, a copy of your sales  
receipt, and a detailed description of the problem,  
including how we can duplicate it.  
Try the same source signal in another channel,  
set up exactly like the suspect channel.  
Bad Output  
Is the associated level knob (if any) turned up?  
6. Write the Service Request Number in BIG PRINT  
on top of the box. Units sent without the SR number  
will be refused.  
If it’s one of the MAIN OUTS, try unplugging  
all the others. For example, if it’s the 1⁄4"  
Left Main out, unplug the RCA and XLR Left  
outputs. If the problem goes away, its not the  
mixer.  
7. Tech Support will tell you where to ship the unit for  
repair. We suggest insurance for all forms of cart-  
age.  
If it’s a stereo pair, try switching them around.  
For example, if a left output is presumed dead,  
switch the left and right cords, at the mixer  
end. If the problem switches sides, it’s not the  
mixer.  
8. You will need to contact the authorized service  
center for their latest turn-around times. The unit  
must be packaged in its original packing box, and  
must have the Service Request Number on the box.  
Once it’s repaired, the authorized service center  
will ship it back by ground shipping, pre-paid (if it  
was a warranty repair).  
Noise  
Turn the channel GAIN and STEREO RETURN  
knobs down, one by one. If the sound disap-  
pears, it’s either that channel or whatever is  
plugged into it, so unplug whatever that is. If  
the noise disappears, it’s from your whatever.  
Note: Under the terms of the warranty, you must ship or  
drop-off the unit to an authorized service center.  
The return ground shipment is covered for those  
units deemed by us to be under warranty.  
Note: You must have a sales receipt from an authorized  
Mackie dealer for your unit to be considered for  
warranty repair.  
Power  
Unplug the power cord and check the fuse.

Appendix B: Connections  
“XLR” Connectors  
You can cook up your own adapter for a stereo  
microphone adapter. “Y” two cables out of a  
female 1⁄4" TRS jack to two male XLR plugs,  
one for the Right signal and one for the Left.  
Mackie mixers use 3-pin female “XLR” connectors on  
all microphone inputs, with pin 1 wired to the grounded  
(earthed) shield, pin 2 wired to the “high” (”hot” or  
positive polarity) side of the audio signal and pin 3  
wired to the “low” (“cold” or negative polarity) side of  
the signal. See Figure A. This is all totally aboveboard  
and in full accord with the hallowed standards dictated  
by the AES (Audio Engineering Society).  
Balanced mono circuits. When wired as a bal-  
anced connector, a 1⁄4" TRS jack or plug is con-  
nected tip to signal high (hot), ring to signal  
low (cold), and sleeve to ground (earth).  
Unbalanced Send/Return circuits. When wired  
as send/return “Y” connector, a 1⁄4" TRS jack  
or plug is connected tip to signal send (output  
from mixer), ring to signal return (input back  
into mixer), and sleeve to ground (earth).  
Use a male “XLR”-type connector, usually found on the  
nether end of what is called a “mic cable,” to connect to  
a female XLR jack.

Switches can be incorporated into 1⁄4" phone jacks,  
which are activated by inserting the plug. These switch-  
es may open an insert loop in a circuit, change the input  
routing of the signal or serve other functions. Mackie  
uses switches in the channel insert and bus insert jacks,  
input jacks and AUX returns. We also use these switches  
to ground the line-level inputs when nothing is plugged  
into them.  
TRS jacks and plugs are used in several different ap-  
plications:  
Stereo Headphones, and rarely, stereo micro-  
phones and stereo line connections.  
When wired for stereo, a 1⁄4" TRS jack or plug  
is connected tip to left, ring to right and sleeve  
to ground (earth). Mackie mixers do not  
directly accept 1-plug-type stereo microphones.  
They must be separated into a left cord and a  
right cord, which are plugged into the two mic  
preamps.  
In most cases, the plug must be inserted fully to  
activate the switch. Mackie takes advantage of this in  
some circuits, specifying circumstances where you are  
to insert the plug only partially. See Special Mackie  
Connections, on the next page.

RCA Plugs and Jacks  
Special Mackie Connections  
RCA-type plugs (also known as phono plugs) and  
jacks are often used in home stereo and video equip-  
ment and in many other applications (Figure D). They  
are unbalanced and electrically identical to a 1⁄4" TS  
The balanced-to-unbalanced connection has been  
anticipated in the wiring of Mackie jacks. A 14" TS plug  
inserted into a 14" TRS balanced input, for example,  
will automatically unbalance the input and make all the  
phone plug or jack (see Figure C). Connect the signal to right connections. Conversely, a 14" TRS plug inserted  
the center post and the ground (earth) or shield to the  
surrounding “basket.”  
into a 14" unbalanced input will automatically tie the  
ring (low or cold) to ground (earth).  
TRS Send/Receive Insert Jacks  
SLEEVE TIP SLEEVE TIP  
Mackie’s single-jack inserts 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. See Figure E.

(TRS plug)

In most studio, stage and sound reinforcement situ-  
ations, there is a combination of balanced and unbal-  
anced inputs and outputs on the various pieces of  
equipment. This usually will not be a problem in making  
connections.  
This plug connects to one of the  
mixer’s Channel Insert jacks.  
“ring”  
RETURN from processor  
Figure E  
The sleeve is the common ground (earth) for both  
signals. The send from the mixer to the external unit is  
carried on the tip, and the return from the unit to the  
mixer is on the ring.  
When connecting a balanced output to an  
unbalanced input, be sure the signal high (hot)  
connections are wired to each other, and that  
the balanced signal low (cold) goes to the  
ground (earth) connection at the unbalanced  
input. In most cases, the balanced ground  
(earth) will also be connected to the ground  
(earth) at the unbalanced input. If there are  
ground-loop problems, this connection may be  
left disconnected at the balanced end.  
Using the Send Only on an Insert Jack  
If you insert a TS (mono) 1⁄4" plug only partially (to  
the first click) into a Mackie insert jack, the plug will  
not activate the jack switch and will not open the insert  
loop in the circuit (thereby allowing the channel signal  
to continue on its merry way through the mixer).  
When connecting an unbalanced output to a  
balanced input, be sure that the signal high  
(hot) connections are wired to each other. The  
unbalanced ground (earth) connection should  
be wired to the low (cold) and the ground  
(earth) connections of the balanced input. If  
there are ground-loop problems, try connecting  
the unbalanced ground (earth) connection only  
to the input low (cold) connection, and leaving  
the input ground (earth) connection discon-  
nected.  
This allows you to tap out the channel or bus signal  
without interrupting normal operation.  
If you push the 1⁄4" TS plug in to the second click, you  
will open the jack switch and create a direct out, which  
does interrupt the signal in that channel. See Figure F  
on the next page.  
NOTE: Do not overload or short-circuit the signal you  
are tapping from the mixer. That will affect the internal  
signal.  
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.

A stereo signal, having two plugs, should be patched  
into the LEFT (MONO) and the RIGHT input or return  
jacks. A jack switch in the RIGHT jack will disable the  
mono function, and the signals will show up in stereo.  
MONO PLUG  
Channel Insert jack  
Direct out with no signal interruption to master.  
Insert only to first “click.”  
A mono signal connected to the RIGHT jack will show  
up in the right bus only. You probably will only want to  
use this sophisticated effect for special occasions.  
MONO PLUG  
Channel Insert jack  
Mults and “Y”s  
Direct out with signal interruption to master.  
Insert all the way in to the second “click.”  
A mult or “Y” connector allows you to route one output  
to two or more inputs by simply providing parallel wir-  
ing connections. You can make “Y”s and mults for the  
outputs of both unbalanced and balanced circuits.  
STEREO  
PLUG  
Channel Insert jack  
Remember: Only mult or “Y” one 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.”

Mackie Stereo Inputs and Returns: Mono,  
Stereo, Whatever  
Stereo line inputs and stereo returns are a fine  
example of the Mackie philosophy (which we just made  
up) of Maximum Flexibility with Minimum Headache.  
The inputs and returns will automatically be mono or  
stereo, depending upon how you use the jacks. Here’s  
how it works:  
A mono signal should be patched into the input or  
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 of the stereo pair  
of buses it’s assigned to, or it can be “panned” with the  
Balance control.
