Main and Subs Mix

70. SUB ASSIGN

One popular use of the su/jointfilesconvert/443004/bgroups is to use them as

master faders for a group of channels on their way to the

main mix [73]. Let us say you have a drum kit hogging

up seven channels and you are going to want to fade

them out at a different rate than the other channels.

You do not want to try that with seven hands or seven

ﬁ ngers, so just un-assign these channels from the main

mix and reassign them to su/jointfilesconvert/443004/bgroups 1-2, engage the

assign to main mix left on su/jointfilesconvert/443004/bgroup 1 and assign to main

mix right on su/jointfilesconvert/443004/bgroup 2. Now you may ride the entire

drum mix with two faders - su/jointfilesconvert/443004/bgroups 1 and 2.

If you engage just one assign to main mix button per

su/jointfilesconvert/443004/bgroup (left or right), the signal sent to the main mix

[73] will be the same level as the sub outs [17]. If you

want the su/jointfilesconvert/443004/bgroup to appear in the center of the main

mix, engage both the assign to main mix left and right

buttons. The signal will be sent to both sides.

71. SUB 1-4 FADERS

As you might expect, these faders control the levels of

the signals sent to the sub outs [17]. All channels that

are assigned to su/jointfilesconvert/443004/bgroups, not muted, and not turned

fully down will appear at the sub outs. Unlike the main

outs [8, 10], the su/jointfilesconvert/443004/bgroup signals do not pass through

an insert jack on their way to the su/jointfilesconvert/443004/bgroup faders. That

is not a problem - should you want to send these signals

through a serial effects processsor, simply patch from

the sub outs to the effect's input, and from the effect's

output to whatever the ﬁ nal destination is, usually a

multitrack recorder.

The su/jointfilesconvert/443004/bgroup signal is off when its 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 su/jointfilesconvert/443004/bgroups as a stereo pair, su/jointfilesconvert/443004/bgroup 1 and 2 for

example, make sure that both su/jointfilesconvert/443004/bgroup faders "ride"

together to maintain the left/right balance.

72. SUBS 1-4 TO FW 5-8

Engage this button, located just below the su/jointfilesconvert/443004/bgroup

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' section to the left, you

can assign a group of channels to su/jointfilesconvert/443004/bgroups and then

re-assign those su/jointfilesconvert/443004/bgroups 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 su/jointfilesconvert/443004/bgroups 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 su/jointfilesconvert/443004/bgroups 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).
