33. TALKBACK to PHONES

Push in the CR/PHONES switch to route the talkback

signal to the PHONES (42) output. Use this to commu-

nicate with the talent in the

studio through the head-

phones during a recording session.

When the talkback

circuit is activated (by pushing the TALKBACK (35)

switch), the CONTROL ROOM outputs are attenuated by

20 dB to allow the engineer’s voice to come through loud

and clear.

34. TALKBACK to AUX 1-2

This switch routes the talkback signal to the AUX 1

and 2 outputs (38). Use this to communicate with the

musicians on-stage through their monitors during a live

performance.

By the way, it is okay to have both destination switch-

es pushed in at the same time. The talkback signal will

be routed to both destinations. But if you don’t have ei-

ther of the destination switches pushed in, the talkback

signal won’t go anywhere. You might as well be talking to

a brick wall.

35. TALKBACK Switch

This is a momentary switch, meaning it’s only active

when you hold the switch down. As long as you hold

this switch down, the talkback signal is routed to the

outputs determined by the destination switches (33/34).

Release the switch, and the talkback circuit is turned off.

MAIN MIX and POWER LED

These are a few more important features that

shouldn’t be overlooked.

36. MAIN MIX Fader

The MAIN MIX fader controls the output level just

before the MAIN OUTPUTS (1/4" and XLR) (40/46) and

the TAPE OUTPUTS (41). When MAIN MIX is selected

for the CONTROL ROOM/PHONES SOURCE (20), the

MAIN MIX fader also controls the main mix level in the

CONTROL ROOM and PHONES outputs (48/42).

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.

37. POWER LED

This LED performs one function—it lets you know

when the Onyx 1220 is turned on and ready to go!
