GAIN SETTINGS LINE CHANNELS
The input-sensitivity can be adjusted for each line input. This can be done by replacing an internal
resistor. When the cover is opened two conventional zero-ohm resistors can be found, just above
the input selector of each channel. See the drawing below. When the resistor values are increased
the input-sensitivity will drop. See the graph below for the resistor-attenuation curve.

The resistor for the left and the right channel must have the same value!

QUALISERS
All microphone channels have an internal two-band equaliser. This equaliser is activated when the
microphone-input is selected.
To adjust the equaliser settings the cover has to be removed. On the PCB two black trimmers can
be found for each microphone channel. See the drawing below.
With a small screwdriver the level can be adjusted. As default both trimmers are in centre position
(this means no equalisation). The maximum adjustment is +/- 18dB.
