Talk-Back requires the Auricula plug-in Monitor to function properly.
Place on a mic -> cue mix channel. The mic would be located in the control room. Signal would only pass to the cue mix when the talk-back switch is depressed – simultaneously, this would mute the control room monitors by 30 dB, suppressing feedback. WARNING: Improper use could result in LOUD signals.
This plug-in has no parameters. You should keep its GUI hidden. Be VERY hesitant, maybe even PARANOID, about bypassing this plug-in. (LOUD) feedback could result.
