Owner's Manual 33. TALKBACK to PHONES 37. POWER LED Push in the CR/PHONES switch to route the talkback signal to the PHONES (42) output. Use this to communicate with the talent in the studio through the headphones 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. This LED performs one function-it lets you know when the Onyx 1220 is turned on and ready to go! 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 switches pushed in at the same time. The talkback signal will be routed to both destinations. But if you don't have either 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.

When MAIN MIX is selected for the CONTROL ROOM/PHONES SOURCE (20), the 5 MAIN MIX fader also controls the main mix level in the 10 CONTROL ROOM and PHONES outputs (48/42). EXTERNAL MIC 20 When the fader is fully down, the MAIN MIX is off. The "U" marking indicates unity gain, and fully up pro- DESTINATION 30 vides 10 dB of additional gain. Typically, this fader is set 40 near the "U" label and left alone, but it can be used for CR/ AUX 50 60 song fade-outs or quick system-wide mutes. PHONES 1-2 TALKBACK Owner's Manual 17
