DEVICE DESCRIPTIONS

Pin-Assignment Of XLRF-Type Connectors:

The pin-assignment of the MIC/LINE input's XLRF-type connector 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 connection plug.

Internal Settings:

1.AUX input sensitivity

The input levels can be set in a range of -10 dBu to +12 dBu using trimmers VR2 (AUX 1) and VR3 (AUX 2). The trim-potentiometers’ coarse scales are meant for your convenience, helping you in adjusting the levels.

Potentiometer setting	Input level
Left margin	+12 dBu
Center position	-3 dBu
Right margin	-10 dBu

2.MIC / LINE switching and sensitivity setting for the MIC / LINE input

The MIC / LINE input's internal PAD-switch (S1) allows switching the channels' sensitivity between microphone and line level (30 dB). The GAIN-control on the module's front panel is provided to precisely adjust the input sensitivity (range 40 dB).
