Channel Strip Description

check out what a particular channel 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 5. 

Soloed channels are sent to the source mix, which 

ultimately feeds your control room, phones and meter 
display. 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!

WARNING: 

Pre-fader solo taps the 

 

channel  signal before the level knob. 

 

If you have a channel’s level knob set below 

“U” (unity gain), solo won’t know that and will send 

 

a unity gain signal to the control room, phones and 
meter display. That may result in a startling level boost 
at these outputs.

25. Mute/Alt 3–4

The dual-purpose mute/alt 3–4 bus is our signature. 

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 route the 
signal somewhere else useful… like a separate 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 
press this switch, you will assign a channel to these 

 

unused outputs, disconnecting it from the main mix, 
and 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. Here are 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 [16] 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 at the control room 

The eight channel strips look alike, and function 

 

identically. The only difference is that the four 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

VLZ4 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! You were smart — you're 
using a 1202VLZ4.

23. Level

This adjusts the channel’s 

level… from off, to unity gain 

 

at the detent, on up to 12 dB 

 

of additional gain.

The level knob is the 

 

equivalent of a channel fader, 

 

so sometimes we lapse and say 
the word fader. 

Channels 1 through 4 use mono 

controls, and channels 5 through 
12 use stereo controls, and so 
they may feel slightly different. 
Not a problem.

24. Pre-Fader 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 level [23] knob 

turned up. Folks use solo in live work to preview 

 

channels before they are let into the mix, or to just
