The MIC control gives
continuous adjustment of the
mic amp gain from + 15dB to +
70dB.
The LINE control gives
continuous adjustment of the
line amp gain from - 20dB to +
20dB.
The LINE switch connects the
line input to the signal path and
disconnects the mic amplifier.
This switch is under automation
control.
The LO PASS filter control acts
on the mic input only and is
continuously adjustable from
1K to 40K. When the filter is
set to 40K there is no loss at
20K.
The HI PASS filter control acts
on the mic input only and is
continuously adjustable from
10Hz to 400Hz. When the filter
is set to 10Hz there is no loss at
20Hz.
The PHASE switch activates
a 180 degrees phase change
on both the mic and line
inputs. This switch is under
automation control.
The METER monitors the
peak signal level of the input
channel pre fader. When the
GLOBAL METER CHANGE
OVER switch on the
COMMS module is activated
the meter monitors the mic
amp or line amp output
(which ever is in use ).
The 48V switch connects 48
volt phantom power to the
mic input suitable for a
condenser microphone or DI
box.
The PAD switch gives 20dB
of attenuation to the mic
signal and will allow the
connection of high output
microphones or line level
signals. If the mic amp is
transformer coupled ( option )
the pad greatly reduces the
risk of saturation at very low
frequencies.
