Gain
The gain control can be used to adjust the preamplification.
For microphone signals, a preamplification of up to 68 dB
can be realized. When optionally equipped with an input
transformer, approximately +14 dB must be added to the
scaled values.
dB | Mic %
The control range for line signals ranges between -20 dB and +16 dB.
The control range for instrument signals ranges between -6 dB und +30 dB.
48V
The 48V switch activates the phantom power of 48 volts
