Owner's Manual

Tape is the stereo signal coming in from the tape in
RCA jacks. FireWire is a 2-track feed coming in through
the FireWire connection from your computer. Alt 3-4 is
the additional stereo mix bus formed when any channel
is muted with the mute/alt 3-4 switch [34].
Selections made here deliver stereo signals to the
control room, phones, and meters. With no switches or
main mix [38] engaged, there will be no signal at these
outputs and no meter indication.
The exception is the solo function. Regardless of
the source matrix selection, engaging a channel’s solo
switch will replace that selection with the solo signal,
sent to the control room, phones, and the right meter.
40. ASSIGN TO MAIN MIX
Let’s say you’re doing a live show. "You're doing a live
show." Intermission is nearing and you want to play a
soothing CD for the crowd to prevent them from becom
-
ing antsy. Simply engage this switch and your source
matrix selection, after going through the control room
level control, will feed into the main mix, just as if it
were another stereo channel.
What if you have a playlist of MP3 files on your com
-
puter you want to play during the break? Engage the
FireWire button to play your MP3s directly from your
computer, through the source matrix, and into the main
mix.
Another handy use for this switch is to enable the alt
3-4 mix to become a submix of the main mix, using the
control room level control.
Side effects to engaging this switch:
1. It will also feed any soloed channels into the
main mix, which may be the last thing you
want.
2. If you have main mix as your source matrix
selection and then engage this switch, the main
mix lines to the source matrix will be discon-
nected from the control room and phones
outputs, to prevent feedback.
3. If you have tape as your source matrix selec-
tion, and then engage this switch, it can create
a feedback path between tape in and tape out.
Make sure your tape deck is not in record,
record-pause, or input monitor mode when you
engage these switches, or make sure the con-
trol room knob [41] is turned all the way down.
41. CONTROL ROOM Knob
This controls the volume at the control room outputs,
from off to maximum gain (+10 dB). It also controls the
level of the control room signal going to the main outs
when assign to main mix [40] is selected.

Control Room/Phones and
Meters
Typically, the engineer sends the main mix to an audi-
ence (for a live show) or to a mixdown deck (if record-
ing). But what if the engineer needs to hear something
other than the main mix in the control room or head-
phones? With the Onyx 820i, the engineer has several
choices of what to listen to. This is one of those tricky
parts, so buckle up.
38. MAIN MIX
Press this switch in to listen to the main mix in your
control room and headphones, and to check the main
mix levels in the meters. In addition to the main mix,
you can listen to any combination of tape, FW 1-2 and
alt 3-4, depending on which of these switches [39] is
engaged.
If the assign to main mix switch [40] is
engaged, you cannot hear the main mix in the
control room or headphones, or see its level
on the meters. This is to prevent feedback caused by
sending the main mix to the main mix.
39. TAPE, FW 1-2, ALT 3-4
Using these source switches, you can choose to listen
to any combination of alt 3-4, tape, and FireWire in the
control room and headphones, in addition to the main
mix if its switch [38] is engaged.
