Mackie ONYX 820i Music Mixer User Manual


 
Owner's Manual 27
The aux 1-2 switch routes the talkback signal to the
aux send 1 and 2 outputs [12]. Use this to communicate
with the musicians through their stage monitors when
you are setting up a live performance.
It is fi ne 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.
54. 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
55. MAIN MIX
This stereo control allows you to adjust the levels of
the main mix signals sent to the XLR and 1/4" main line-
level outputs [4, 14], and the tape outputs [16].
This gives you the ultimate feeling of power and
control over the sound levels sent to your audience. If
you press the main mix switch [38], you can see the
main mix levels in the meters [43]. Adjust this control
carefully, 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 control does not affect the aux outputs [12],
alt 3-4 outputs [7], or the main mix FireWire outputs
7-8. It affects the control room or headphones if the
main mix switch [38] is engaged.
The main mix signals are off with the knob 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 control to slowly bring down at the end of a
song (or quickly in the middle of a song if the need ever
arises).
56. ASSIGN TO FW 7–8
This switch allows you to assign the left and right
main mix to FireWire outputs 7 and 8. For example, you
can record 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 level control [55].
When this switch is disengaged, then mixer
channels 7 and 8 are assigned to FireWire
outputs 7 and 8 instead.
Congratulations! You’ve just read about all the
features of your mixer. Time for a frosty beverage.
