Pin-Assignment Of XLRM-Type Connectors:
The LINE output XLR-connectors' pin-assignment is as follows: pin 1 = screen, Pin 2 = positive conductor, pin 3 =
negative conductor. In unbalanced configuration the pins 3 (-) and 1 (screen) have to be bridged inside the
connected plug.

Setting Output Levels Via Jumpers:
Each of the two outputs' output level can be set to 0 dB or +6 dB using the jumpers JP1 and JP2. Please make
sure to set both jumpers of an output channel (A / B) to the desired position.
When shipped, the output levels for both output channels are factory pre-set to 0 dB (all jumpers are closed).
