ALL)) This is a female 1/4" TRS connector for
terminating balanced lower high impedance line level
circuits. Tip is positive, ring is negative. This circuit is
wired in parallel with the female XLR connector. This
input is connected through a 20 dB pad to the Mic
input. Connecting to this input will not disable the XLR
input connector, so both inputs should NOT be used
simultaneously.

C This is a female XLR connector for terminating
balanced, low impedance microphone circuits. Pin 2 is positive and +48 V DC
is applied to pins 2 and 3 via a resistive network when the front panel
Phantom Power switch is ON.

range is +10 to +56 dB for microphone level inputs and -10 to +36 dB for line
level inputs. The output of this gain stage also drives the SIG/PFL LED.

D This switch mutes all Aux, Sub, L/R,
and Mono sends from the corresponding channel. The switch is equipped
with a red LED that will illuminate when the channel is muted. When the
Mute switch is disengaged, the LED functions as a clip (PK) indicator that
will illuminate at 2 dB below clipping. Muting the channel does not prevent
the PFL signal from being sent to the PFL mix when the PFL switch is
engaged.
