 AUX 1 SELECT
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 MS1402-VLZ, 
AUX SEND 1 can play either
role, depending on the position of this switch.
With the 
AUX 1 SELECT switch up (disen-
gaged), 
AUX SEND 1 will tap a channel
pre-
FADER and pre-MUTE/ALT 3-4, meaning
that no matter how you manipulate those con-
trols as they feed the 
MAIN MIX, the AUX
SEND will continue to belt out a constant sig-
nal level. This is the preferred method for
setting up stage monitor feeds. 
EQ settings
will affect all 
AUX SENDS.
With the switch down, 
AUX SEND 1 be-
comes an ordinary effects send — 
post-
FADER
and 
post-
MUTE/ALT 3-4. This is a must for ef-
fects sends, since you want the levels of your
“wet” signals to follow the level of the “dry.”
 AUX 1 MASTER
The 
AUX 1 MASTER provides overall level
control of 
AUX SEND 1, just before it’s deliv-
ered to the 
AUX 1 OUTPUT. (AUX SEND 2 has
no such control.) This knob goes from 
off
(turned fully down), to Unity gain at the center
detent, with 10dB 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.
This is usually the knob you turn up when
the lead singer glares at you, points at his
stage monitor, and sticks his thumb up in the
air. (It would follow suit that if the singer
stuck his thumb down, you’d turn the knob
down, but that never happens.)
 AUX RETURNS
These two controls set the overall level of
effects received from 
STEREO AUX RETURN in-
puts
 1 and 2  . These controls are designed to
handle a wide range of signal levels, from 
off, to
unity gain at the detent, with 20dB gain fully
clockwise, to compensate for low-level effects.
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 ef-
fects device’s outputs, not the mixer. That way,
the mixer’s knobs are easy to relocate at the
center detent.
 AUX TALK
First of all, there is no par-
ticular alliance between 
AUX
SEND 1 (or 2) and AUX
RETURN 1 (or 2). They’re
just numbers. They’re like two complete
strangers, both named Fred.
Here’s the whole idea behind sends and re-
turns: sends are outputs, returns are inputs.
AUX SENDs tap signals off the channels, via
their 
AUX knobs  , mix these signals, then
send them out via the 
AUX SEND jacks  .
These outputs are fed to the inputs of a re-
verb or other device. From there, the outputs of
this external device are fed back to the mixer’s
AUX RETURN jacks  . Then these signals are
sent through the 
AUX RETURN level controls,
and finally delivered to the 
MAIN MIX.
So, the original “dry” signals go from the
channels to the 
MAIN MIX and the affected
“wet” signals go from the Aux Returns to the
MAIN MIX, and once mixed together, the dry
and wet signals combine to create a glorious
sound. So, armed with this knowledge, let’s
visit the Auxiliary World:
