This knob allows engineer’s listening levels to be set as desired without disturbing the main mix outputs. Engaging TAPE RETURN TO
When a channel’s SOLO (39) is engaged, the main mix signal will be replaced by the solo signal(s), allowing the engineer to audition channels without disturbing the main mix.
To prevent the possibility of feedback, engaging either talkback switch (67) (68) will attenuate control room output levels by 20dB.

TALKBACK
Ordinarily, the main mix (or solo) stereo signals are sent to CONTROL ROOM OUT (11), MAIN OUTS (12) (16), MONO MAIN OUT (14), PHONES (18) and METERS (54). Engaging this switch will replace these signals with stereo signals from the TAPE IN (6) jacks, via the TAPE RETURN (53) level control.
Also known as a “break switch,” this switch is useful for live sound, to play recorded entertainment between sets. It can also serve as a global mute switch simply by patching nothing

72. MAIN MIX FADERThis fader controls the main mix levels sent to CONTROL ROOM OUT (11), MAIN OUTS
(12)(16), MONO MAIN OUT (14), PHONES
(18)and METERS (54). The stereo main mix can be processed before this fader by patching an effects device into the MAIN INSERTS
The fader turned fully up provides 10 dB of additional gain, the “U” label is unity gain and fully down is effectively muted. Typically, this fader is set near the “U” label and left alone, but it can be used for song
