SUB 1-4 Faders

As you might expect, these faders control the levels of

the signals sent to the SUB OUTS. All channels that are

assigned to su/jointfilesconvert/1253494/bgroups, not muted, and not turned fully

down will appear at the SUB OUTS. Unlike the MAIN

OUT, the su/jointfilesconvert/1253494/bgroup signals do not pass through an insert

jack on their way to the su/jointfilesconvert/1253494/bgroup faders. That’s no prob-

lem—should you want to send these signals through a se-

rial effects processor, simply patch from the SUB OUTS to

the effect’s input, and from the effect’s ouput to whatever

the ﬁ nal destination is, usually a multitrack recorder.

The su/jointfilesconvert/1253494/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’re treating two

su/jointfilesconvert/1253494/bgroups as a stereo pair, su/jointfilesconvert/1253494/bgroup 1 and 2 for exam-

ple, make sure that both su/jointfilesconvert/1253494/bgroup faders “ride” together

to maintain the left/right balance.

43. SUB ASSIGN

One popular use of the su/jointfilesconvert/1253494/bgroups is to use them as master

faders for a group of channels on their way to the MAIN MIX.

Let’s say you’ve got a drum kit hogging up seven channels

and you’re going to want to fade them out at a different rate

than the other channels. You don’t want to try that with sev-

en hands or seven ﬁ ngers, so just un-assign these channels

from the MAIN MIX, reassign them to su/jointfilesconvert/1253494/bgroups 1-2, engage

the ASSIGN TO MAIN MIX LEFT on su/jointfilesconvert/1253494/bgroup 1 and ASSIGN

TO MAIN MIX RIGHT on su/jointfilesconvert/1253494/bgroup 2. Now you can ride the

entire drum mix with two faders—su/jointfilesconvert/1253494/bgroups 1 and 2.

If you engage just one ASSIGN TO MAIN MIX button

per su/jointfilesconvert/1253494/bgroup (LEFT or RIGHT), the signal sent to the

MAIN MIX will be the same level as the SUB OUTS. If

you want the su/jointfilesconvert/1253494/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.

POWER LED

This LED performs one function—it lets you know

when the Onyx 1640 is turned on and ready to go!

46. MAIN MIX Fader

The MAIN MIX fader controls the output level just

before the MAIN OUTPUTS (1/4

and XLR) [52/54] and

the TAPE OUTPUTS [58]. When MAIN MIX is selected for

the CONTROL ROOM/PHONES SOURCE [18], the MAIN

MIX fader [46] also controls the main mix level in the

CONTROL ROOM and PHONES outputs [59/30].

When the fader is fully down, the MAIN MIX is off.

The “U” marking indicates unity gain, and fully up pro-

vides 10 dB of additional gain. Typically, this fader is set

near the “U” label and left alone, but it can be used for

song fade-outs or quick system-wide mutes.

These two knobs feed their respective stereo AUX

RETURN signals to a mono summing amp and then: TO

AUX 5 feeds AUX RETURN 1 to AUX SEND 5 master, and

TO AUX 6 feeds AUX RETURN 2 to AUX SEND 6 master.

They are off when turned fully down, and provide up to

10 dB gain turned fully up.

41. AUX RETURN 3 SEND TO MAIN/SUBS

With this button up, AUX RETURN 3 behaves like the

other AUX RETURNS—it delivers a stereo signal, regu-

lated by its level knob, to the MAIN MIX. When you push

this button in, the AUX RETURN 3 signals are removed

from the MAIN MIX buses and sent to the SUBS 1-2/3-4

switch, which diverts the signal once more. We’re not

ﬁ nished. Please read on.

42. SUBS 1-2/3-4

If the AUX RETURN 3 SEND TO MAIN/SUBS button

is up, the SUBS 1-2/3-4 button does absolutely nothing.

Let’s now assume it is pushed in. AUX RETURN 3’s ste-

reo signal will not be sent to the MAIN MIX, but to the

su/jointfilesconvert/1253494/bgroup faders 1 and 2 (SUBS 1-2/3-4 button up) or to

su/jointfilesconvert/1253494/bgroup faders 3 and 4 (SUBS 1-2/3-4 button down).

Let’s say you’ve made a stereo drum submix on sub-

group faders 1 and 2, so you can ride those two faders

instead of the seven channels that the drums came

from. Su/jointfilesconvert/1253494/bgroup fader 1 has its ASSIGN TO MAIN MIX

LEFT button engaged and su/jointfilesconvert/1253494/bgroup fader 2 has its AS-

SIGN TO MAIN MIX RIGHT button engaged, blending

the drum submix back into the MAIN MIX. The drum

channels are also sending signals to your reverb via the

AUX sends and the reverb outputs are patched into the

AUX RETURN 3. So far, so good.

Even though you could send AUX RETURN 3 directly

to the MAIN MIX (AUX RETURN 3 SEND TO MAIN/

SUBS button up), you don’t want to. Instead, engage the

AUX RETURN 3 SEND TO MAIN/SUBS switch and make

sure the SUBS 1-2/3-4 switch is up. Now the reverb

return is blended into the drum submix, and as you ride

the two su/jointfilesconvert/1253494/bgroup faders, the reverb level will follow.

Why do we want that? Because if you had just sent the

reverb directly to the MAIN MIX (AUX RETURN 3 SEND

TO MAIN/SUBS button up) and you did a drum fade-

out using the su/jointfilesconvert/1253494/bgroup faders 1 and 2, the “dry” signals

would fade out, but the “wet” signals would keep on sing-

ing. All you would hear is the drum reverb (the “wet”),

and none of the original drum signals (the “dry”). That’s

because the reverb is being fed by the channel’s AUX

SEND, and they have no idea that you’ve pulled down the

su/jointfilesconvert/1253494/bgroup faders. That’s why we threw in these switches.
