CONTROLS:
GAIN:
The gain switches have a range from +10dB to +70dB.
Coarse gain 10dB/steps (20-60ddB) and
Fine gain 2dB/step (-10dB to +10dB).
LF cut:
The high pass filter is selectable between off, 20Hz (12dB/octave) and
40Hz (6dB/octave).
Phantom:
The phantom switch switches the +48V DC power on and off.
The +48V DC is supplied to the microphone input via two 6,81 K
resistors.
PAD:
This switch places a -20dB attenuation between the microphone and
the input transformer.
PHASE:
Reverses the phase by 180 degrees on the mic input.
The DI input is unaffected.
IMPEDANCE: The mic. input load impedance can be selected between 600, 1200 and
2400 Ohm.
