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
