Talkback (intercom) Wiring

The console has two audio inputs for use in talkback:

(1) The console has a balanced, line level audio input that feeds the control room monitor speakers (unless muted by a mic) and in the earphones

(whether muted or unmuted).

(2) The console has a second -10dBu unbalanced line level input into the cue system for talkback. The audio on this input will act the same as cue

audio (mute into the cue speakers when a mic is turned on, but autocue into the headphones if the talback logic is activated).

The logic input must be a dry closure between pins 5 (+12V) and pin 6 (logic). This will trigger auto cue so that audio fed into talkback input 2

(cue) will be heard in the headphones.
