INSERT JACK (Typ of Left and Right outputs) Female 1/4” TRS connec-
tor for terminating two, single-ended (unbalanced) line level circuits.
The tip is a line output and carries the signal after the bus summing
stage and before the master fader. The ring is a line input and feeds
the master fader and final gain circuit just before the output ampli-
fiers. Inserting a TRS male connector into this jack will break the
circuit of the output channel. A complete loop must be made to pass
audio through the jack. Inserting a plug so that only the tip makes
connection will provide a line output only, but will break the con-
nection. If a complete connection is required when using this jack as
a line output, it must be made by completing the loop at the plug.
BALANCED OUTPUT (Typ of Left and Right outputs) Male XLR con-
nector for terminating the main bus audio output. The signal is elec-
tronically balanced and Pin 2 carries the positive side of the signal.
The output level is 0 to +26 dBm, depending on the position of the
front panel master Fader. Nominal output is +4 dBu.
BALANCED OUTPUT (Mono output) Male XLR connector for termi-
nating the summed Left and Right audio output. The signal is elec-
tronically balanced and Pin 2 carries the positive side of the signal.
The output level is 0 to +26 dBm, depending on the position of the
front panel L/R master Faders and rear panel Mono Level control.
Nominal output is +4 dBu.
LEVEL (Mono output) Rotary control adjusts the summed mono out-
put. The range is infinity (OFF) to +6 dB for line level inputs. This
control is after the Left/Right fader and before the Mono output bal-
ancing amplifier.
UNBALANCED OUTPUT (Typ of Left and Right outputs) Female 1/4”
TS connector for terminating a single unbalanced line level audio
output. The signal present at this connector is before the balancing
amplifier and after the main output Fader. Both the balanced &
unbalanced L/R outputs can be used simultaneously.
