Onyx 1640i
•
Note: Route the two channels from your
computer through the control
room/headphones or through channels 1
and 2. Do not use both. To retain your signal
source's stereo image, you will need to pan
channel 1 all the way to the left and channel 2
all the way to the right.
FIREWIRE PRE/POST
Each channel of the mixer can send a FireWire output
to your computer or DAW. The FireWire output from
each channel can be tapped before (pre) or after (post)
the channel EQ. (The output is pre-fader.)
If you want the mixer EQ to affect the FireWire
recording, then set this switch to
post
. This is useful
in recording channels in a studio (where the recording
includes the benefi cial effect of our Perkins EQ).
If you would rather record the straight signals from a
live performance, and EQ them later in your DAW, then
set this switch to
pre
. This is good for live work, where
you may have added EQ to adjust for the room, and yet
not want this added to your recording.
INPUT (LINE or FW 1-16)
Mixer channels 1-16 can either be fed from the 1/4"
line-level inputs, or by FireWire outputs 1-16 from your
computer. This switch lets you choose which to use.
Either way, all 16 channels receive line-level analog
audio signals just prior to the gain control, so channel
setup, gain adjustment and EQ adjustment are the same
for line or FireWire.
CONTROL ROOM FW 1-2
If this is engaged, you can listen to FireWire
1 and 2 playback from your computer in the
control room and headphones. This can also be
added to the main mix if control room assign
to main mix is engaged.
Route the two channels from your
computer through the control room/headphones
or through channels 1 and 2. Do not use both.
ASSIGN TO MAIN MIX
Engage the control room FW 1-2 switch and
the "assign to main mix" switch to play two
tracks directly from your computer through the
control room/phones source matrix and into the
main mix. This is great for listening to iTunes
®
or other pre-recorded material from your
computer.
SUBS 1-4 to FW 5-8
Engage this button, located just below the subgroup
faders, and the subs 1-4 mix can be sent to your
computer via Firewire channels 5-8. The sub 1 mix
will appear on FireWire output signal 5, the sub 2 mix
will appear on FireWire output signal 6, and so on. The
FireWire output is affected by the sub faders. (When
this button is engaged, mixer channels 5-8 are not
available to send via FireWire.)
This switch is here for additional fl exibility. As
mentioned in the 'Sub Assign switches' section on page
16 you can assign a group of channels to subgroups and
then re-assign those subgroups to the main mix. In that
example, we assigned the seven channels that were
being hogged by the 'can't-keep-a-steady-beat' drummer
to subgroups 1-2. Still with us?
Now imagine this: We have already successfully
recorded the drummer's tracks from the live show
and are returning them from the computer on tracks
1-7. Each of the seven tracks contains a collection of
processing and quantization. Doing so makes each
individual component of the drum kit sound better...
and in time! Those seven tracks can now be EQ'd on the
Onyx 1640i mixer and routed to subgroups 1-2. These
are then transmitted back for recording to your digital
audio workstation (DAW) via FireWire. This is called
track bounce. The seven tracks have now been reduced
to a stereo pair, allowing us to free up processing power
that may be applied to pitch correction and reverb
plug-ins for the egomaniac vocalist. This is called LSD
(Lead Singer Disease).
