Typically, these knobs can just live at the center
detent, and the effects device’s output control should
be set at whatever they call unity gain (check their
manual). If that turns out to be too loud or too quiet,
adjust the effects device’s outputs, not the mixer.  
That way, the mixer’s knobs are easy to relocate  
at the center detent.
Signals passing through these controls will proceed
directly to main mix, with one exception (see paragraph
below). 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 those channels.
41.  Return To Aux 1
If you want to add reverb or delay to the stage monitor
mixes of aux 1, this is the switch for you.
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
something in the right side, that normalled connection
is broken.
How does all this relate to the
return to aux 1 [41] 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 return 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 aux return 1. Say that ten times
fast! Once again, aux return 1 will behave normally, as
always.
Congratulations! You’ve just read about all the  
features of your 1202VLZ4. You’re probably ready for  
a cold one. Go ahead. The rest of the manual can wait.
