The aux 1-2 switch routes the talkback signal to the
aux send 1 and 2 outputs [6]. Use this to communicate
with the musicians through their stage monitors when
you are setting up a live performance.
It is fine to have both destination switches pushed in
at the same time, so the talkback signal will be routed
to both destinations. But if you don’t have either of the
destination switches pushed in, the talkback signal
won’t go anywhere. You might as well be talking to a
brick wall.
50. TALKBACK Switch
This is a momentary switch, and as long as you hold it
down, talkback is activated. You can talk into the built-
in microphone and be heard in the headphones and/or
stage monitors.
Release the switch so you can talk about the band
without them hearing you.
Main Mix
51. MAIN MIX
This stereo fader allows you to adjust the levels of the
main mix signals sent to the XLR and 1/4" main line-
level outputs [4, 13], and the tape outputs [16].
This gives you the ultimate feeling of power and con-
trol over the sound levels sent to your audience. If you
press the main mix switch [35], you can see the main
mix levels in the meters [40]. Adjust this control care-
fully, with your good eye on the meters to check against
overloading, and your good ear to the levels to make
sure your audience (if any) is happy.
This fader does not affect the aux send outputs [6],
alt 3-4 outputs [14], or the main mix FireWire outputs
11-12. It affects the control room or headphones if the
main mix switch [35] is engaged.
The main mix signals are off with the fader fully down,
the “U” marking is unity gain, and fully up provides 10
dB of additional gain. This additional gain will typically
never be needed, but once again, it’s nice to know that
it’s there. The fader is stereo, as it affects both the left
and right of the main mix equally. This is the ideal con-
trol to slowly bring down at the end of a song (or quickly
in the middle of a song if the need ever arises).
MAIN MIX and FIREWIRE
The left and right main mix are permanently assigned
to FireWire outputs 11 and 12. For example, you can re-
cord the live performance main mix onto your computer.
This does not affect the analog main mix outputs.
The output level to your computer is not affected by
the main mix fader [51].
Congratulations! You’ve just read about all the fea
-
tures of your mixer. Time for a frosty beverage.
