Internal Settings:

1.MIC / LINE switching and sensitivity of the MIC / LINE input

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

In addition, a MIC/LINE jumper (JP1, pins 5-6) is located on the printed board assembly, which allows correctly configuring the input. It is important to change the jumper accordingly (open = LINE, closed = MIC) when changing the MIC/LINE switch.

When shipped the switch S1 is pre-set to LINE and the jumper JP1 to its open position.

2.Phantom power

Closing the pins 1-2 and 3-4 of the jumper JP1 offers the possibility to engage 24 V phantom power for microphones that are connected directly. When shipped, the jumper is factory pre-set to its “open” position (no phantom power).

3.Compressor / Limiter

The MIC / LINE input channel embodies a compressor / limiter circuit which can be incorporated into the signal path via jumper JP2 (position COMP). Normally, the compressor / limiter should be used to eliminate the risks of overdrive and clipping, when directly connecting a microphone. When shipped, the jumper is pre- set to its “Linear” position (LIN).
