37. AUX SENDS SOLO
This button allows you to solo an individual AUX
SEND. If you are using the aux sends to feed your stage
monitors, you can use these buttons to check your moni-
tor 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), 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
next to the AUX SEND MASTERS.
38. AUX 1-4 RETURNS
These four controls set the overall level of effects
received from the stereo AUX RETURN 1-4 inputs [61].
These controls range from off (∞) to +10 dB of gain
when fully clockwise, to compensate for low-level effects.
Signals passing through the AUX RETURN level con-
trols proceed directly to the MAIN MIX bus where they
are combined with the other channels just before the
MAIN MIX fader [38].
39. AUX RETURN 4 to CR/PHONES ONLY
When this button is up, AUX RETURN 4 is routed to
the MAIN MIX bus, just as the AUX RETURNS 1-3 are.
When the button is down, the AUX RETURN 4 stereo
signal is routed to the CR/PHONES matrix instead. It
doesn’t matter if any of the SOURCE buttons are as-
signed, but it will be interrupted, as usual, if a SOLO
button is engaged.
Let’s pretend you’re doing a live mix to a 2-track deck,
a house PA, or both, and you want to play along to a
click track. You could run the click track directly into
the MAIN MIX, but you don’t want the mixdown deck
or the audience to hear it. Oh yeah, you can route it to
the control room and phones output instead! Similarly,
it can be used for voice-over tracks, narration, anything
you want heard by the engineer and players but not by
the audience and mixdown deck.
40. EFX TO MON Level Controls
These controls route the signal from AUX RETURNS
1 and 2 to the AUX 5 and 6 SENDS. This allows you to
use an external effects device, like a reverb or delay,
exclusively for the monitors. When these controls are
turned up, the stereo effects return signal is summed
to mono and combined with the signals coming from all
the channel AUX 5 and AUX 6 send controls.
If you want to add reverb or delay to the stage monitor
mixes, these are the knobs for you. Operating indepen-
dently of their respectively numbered AUX RETURNS
level controls, these knobs are exactly the same as the
AUX 5 and AUX 6 knobs found in the channel strip.
