DEVICE DESCRIPTIONS

2.Phantom Power

By closing the jumpers JP1, pins 1-2 and pins 3-4 (IN A) respectively JP2, pins 1-2 and pins 3-4 (IN B), it is possible to (separately) engage 24 V phantom power when a microphone is connected to the corresponding input. When shipped, jumpers are set to “open” (no phantom power).

3.Compressor / Limiter

The MIC / LINE input channels embody compressor / limiter circuits, which can be incorporated in the signal paths via the jumpers JP3 for IN A and JP4 for IN B (position “COMP”), if needed. Normally, the compressors / limiters should be used to eliminate the risks of overdrive and clipping, when directly connecting microphones. When shipped, the jumpers are set to “LIN”.

retrofitting the input transformers, internal settings, location of parts (NRS 90217)

Retrofitting Input Transformers:

In case galvanic separation of the audio signals is necessary, the module can be retrofitted with two input transformers. This is accomplished by using an extension kit NRS 90233 per input channel.

When retrofitting input transformers, please proceed as follows:

1.Disconnect the DPM 4000 from the mains power supply.

2.Loosen the two locking screws and carefully slide the module out of the slot..

3.Remove the two resistors of the correspondent input channel (IN A: R2 / R3, IN B: R10 / R11).

4.Solder the transformer for IN A in position T1 and for IN B in position T2 onto the printed board assembly.

5.Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.

6.Fix the module in place using the two locking screws and reconnect the power supply.
