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).

Jumper setting	Output	level
JP1, 2-4 / JP2, 2-4	channel A
Open	+6 dB
Closed	0 dB

Jumper setting	Output	level
JP1, 1-3 / JP2, 1-3	channel B
Open	+6 dB
Closed	0 dB

Jumper setting for the output assignment: To be used in network installations.

When used in a network environment, the following jumpers have to be open:

OUT A	LK10,	LK11	(applies to printed board assemblies starting with index C!)
OUT B	LK 8,	LK 9
