SUB 1-4 FADERS
These faders control the levels of the signals sent to
the sub outs. All channels that are assigned to
subgroups, not muted, and not turned fully down will
appear at the sub outs. Unlike the main out, the
subgroup signals do not pass through an insert jack on
the way to the subgroup faders, although effects may
be acquired easily enough. Simply patch from the sub
outs to the effect's input, and from the effect's output to
whatever the fi nal destination may be, typically back in
on one (or more) channel's input jacks.
The subgroup signal is off when the fader is fully
down, the "U" marking is unity gain, and fully up
provides 10 dB additional gain. Remember that if you
are treating two subgroups as a stereo pair, subgroup 1
and 2 for example, make sure that both subgroup faders
"ride" together to maintain the left/right balance.
SUBS 1-4 TO FW 5-8
Engage this button (located just below the sub 2 and
sub 3 fader) and the sub groups can be sent to FireWire
sends 5-8, taking the place of channel direct
outputs 5-8.
This allows the user to combine different channels on
to subgroups and record material to separate tracks on
a DAW. This is particularly useful if FireWire sends 9-14
can not be used because the aux masters have taken
over.
ASSIGN TO FW 15-16
Engage this button (just above the main mix fader)
and the main mix can be sent to your computer via
FireWire. The FireWire output is not affected by the
main mix fader, allowing you to record the main mix
of live performances. The left main mix will appear
on FireWire output signal 15, and the right on signal
16. (When this button is engaged, mixer channels
15-16 are not available to send via FireWire.)
In addition to recording the main mix using FireWire,
you can record individual mixer channels 1-14 using
FireWire (for a total of 16 streams available) for
studio mixing at a later date. See page 19.
RECORDING OUTS
These two DB-25 connectors provide balanced direct
outputs for channels 1-8 and 9-16, respectively.
They are designed to be connected directly to a
recorder's analog inputs, and use the TASCAM
standard pinout for analog signal connections.
The signal at the recording outs comes just after the
input gain control, and before the low-cut switch, insert
jacks, and EQ. This way you can EQ a channel, connect
a compressor or other dynamics processor to the insert
jack, and adjust the channel fader to suit your live mix,
but it has no effect on the signal going to the recorder.
This provides maximum fl exibility for the mixdown
stage.
The recording outputs may also be used in lieu of a
splitter. Picture this: all of the microphones,
instruments, DI's, etc - any input connected to an
Onyx 1640i as a monitor mixer - may then be sent out
from the recording outputs 1-16 directly to the line
inputs of yet another Onyx 1640i used as the front of
house mixer.
