Aux Master
This section includes the aux sends and the aux
returns. Aux sends tap signals off the channels, via the
aux knobs [35], mix these signals from each channel
together, then sends them out the aux send jacks [19]
and FireWire outputs 9-14. The aux sends can be pre-
fader or post-fader (both are post-EQ, but see page 46).
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 [18]. Then these
signals are sent through the aux return level controls
[59], 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 re-
turns aren’t used to return the signal. Instead, they can
be used as additional stereo inputs, or not used at all.
55. MASTER AUX SENDS 1-6
These knobs provide overall control over the aux send
levels, just before they are delivered to the aux send
outputs [19]. These knobs go from off to +15 db when
turned all the way up.
The aux sends can either be pre or post fader, depend-
ing on the position of the aux pre/post switches [56].
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 can also be sent to FireWire outputs
9-14 for recording [58]. The levels to FireWire are af-
fected by these send controls and the pre/post switch.
56. 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 moni-
tors 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.
57. AUX SENDS SOLO
This button allows you to solo an individual aux send.
If you are using the aux sends to feed your stage moni-
tors, you may use these buttons to check your monitor
mix. Beside each switch is an indicating LED to let you
easily spot a soloed aux send.
The aux send solo is not affected by the solo mode
switch (PFL/AFL) [52], except that in PFL mode only
the right meter indicates the signal. The aux send's
PFL/AFL status is determined by the pre/post switches
[56] next to the aux send masters [55].
