70. PHONES/C-R LEVEL
After the MAIN MIX FADER (72), the main
mix is sent to the MAIN OUTS (12) (16) and
MONO MAIN OUT (14). It is also sent through
this control, and exits at CONTROL ROOM
OUT (11) and PHONES (18).
This knob allows engineer’s listening levels
to be set as desired without disturbing the
main mix outputs. Engaging TAPE RETURN
TO PHONES/C-R (69) or TAPE RETURN TO
MAIN MIX (71) will replace the main mix sig-
nal at the control room and phones outputs
with the TAPE IN (6) signal.
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, en-
gaging either talkback switch (67) (68) will
attenuate control room output levels by 20dB.
71. TAPE RETURN TO MAIN MIX
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). En-
gaging 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 enter-
tainment between sets. It can also serve as a
global mute switch simply by patching nothing
into the TAPE IN (6) jacks.
72. MAIN MIX FADER
This 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
(13).
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 fade-outs or quick
system-wide mutes.
