Aux Master
This section includes the aux sends and the aux
returns. Aux sends tap signals off the channels, via the
aux knobs [31], mix these signals from each channel
together, then sends them out the aux send jacks [6]
and FireWire outputs 13 and 14. The aux sends can be
pre-fader or post-fader (both are post-EQ, but see
page 38).
Post-fader aux sends can be fed to the inputs of an
external processor like a reverb or digital delay. From
there, the outputs of this external processor are fed
back to the mixer’s aux return jacks [7]. Then these
signals are sent through the aux return level controls
[47], and finally delivered to the main mix.
So, the original unprocessed “dry” signals go from
the channels to the main mix, and the processed “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!
Pre-fader aux sends are typically used to provide
another mix for stage monitors. In this case, the aux
returns aren’t used to return the signal. Instead, they
can be used as additional stereo inputs, or not used at
all.
45. MASTER AUX SENDS 1-4
These knobs provide overall control over the aux send
levels, just before they are delivered to the aux send
outputs [6]. These knobs go from off to +15 db when
turned all the way up.
The aux sends can either be pre or post fader,
depending on the position of the aux pre/post
switches [46].
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 that if
the singer stuck his thumb down, you’d turn the knob
down, but that never happens.)
The aux sends are also sent to FireWire output 15 and
16 for recording. The levels to FireWire are affected by
these send controls and the pre/post switch.
46. PRE/POST
The pre/post switches determine whether the aux
send signal is tapped from the channels before the
channel level controls (pre-fader) or after (post-fader).
Having a separate pre/post switch for each aux is a
super-useful feature as it allows the use of one effects
processor and one stage monitor chain, at the same
time.
For stage monitor work, use pre, so the stage
monitors do not increase in volume when the channel
level is adjusted.
For external processors, use post. In this way, the feed
to external processors will vary with the channel level,
keeping them in the same ratio, so that the “wet” signal
level follows the “dry” signal level.
47. MASTER AUX RETURNS 1-4
These four controls set the overall level of effects
received from the stereo aux return 1-4 inputs [7].
These controls range from off to +10 db of gain when
fully clockwise, to compensate for low-level effects.
Signals passing through these controls go directly to
the main mix bus where they are combined with the
other channels. Alternatively, aux 3 return can be
routed to aux 1 send instead, using the rtn to aux 1
switch [48] described next.
48. RTN TO AUX 1
This switch routes the signal from aux return 3 to the
aux 1 send mix instead of to the main mix bus.
For example, this allows you to use an external effects
device, like a reverb or delay, exclusively for the
monitors. When this switch is pushed in, the effects
signals coming into the aux return 3 jacks are added to
your aux 1 stage monitor mix. Adjust the effects level
coming in with the aux 3 return controls [47], until it
sounds just right in your monitors.
