Channel Strip Description
The 1402-VLZ3 has "dual-mode solo." The SOLO 
MODE [35] switch in the Master section determines 
which mode you'll be hearing. With the switch up, you'll 
get "AFL" (After-Fader-Listen), which is post-FADER, 
post-PAN, making it ideal for mixdown soloing. With the 
switch down, you're in "PFL" (Pre-Fader-Listen), used 
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! 
25. MUTE/ALT 3–4
The dual-purpose MUTE/ALT 3–4 bus is a Mackie sig-
nature. When Greg was designing our fi rst 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 
route the signal somewhere else useful… like a sepa-
rate stereo bus?” So MUTE/ALT 3–4 really serves two 
functions — muting (often used during a mixdown or 
live show), and signal routing (for multitrack and live 
work) where it acts as an  extra stereo bus.
To use this as a MUTE switch, all you have to do is 
not use the ALT 3–4 [16] outputs. Then, whenever you 
assign a channel to these unused outputs, you’ll also be 
disconnecting it from the main mix, effectively muting 
the channel.
To use this as an ALT 3–4 switch, all you have to do 
is connect the ALT 3–4 outputs to whatever destination 
you desire. Two popular examples:
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 
to control the level of several channels with one knob. 
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.
The ten channel strips look alike, and function identi-
cally. The only difference is that the six on the left are 
for individual mics or mono instruments, and have more 
gain available, while the next four are for either stereo 
or mono line-level sources. (Each of the stereo channel 
strips is actually two complete circuits. The controls are 
linked together to preserve stereo.) We’ll start at the 
 bottom and work our way up… 
“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.
You won’t have to check it here and 
check it there, as you would with some 
other mixers. In fact, some don’t even 
have any reference to actual dB levels 
at all! Ever seen those “0–10” fader 
markings? We call these AUMs (Arbi-
trary Units of Measurement), and they 
mean nothing in the real world. You 
were smart — you bought a Mackie.
23.  CHANNEL FADER
These faders control the channel’s 
level… from off, to unity gain, on up 
to 10 dB of additional gain. Channels 1 
through 6 use mono faders, and chan-
nels 7 through 14 use stereo faders, 
and may feel slightly different. Not a 
problem.
24.  SOLO
This lovable switch allows you to 
hear signals through your headphones 
or control room without having to 
route them to the main mix or ALT 3-4 
mix. You don’t even have to have the 
channel’s fader turned up. Folks use 
solo in live work to preview channels 
before they are let into the mix, or to 
just check out what a particular chan-
nel is up to anytime during a session. 
You can solo as many channels at a 
time as you like.
Solo is also the key player in the 
Level- Setting Procedure on page 3.
