DEVICE DESCRIPTIONS

5.1.7 2-Channel MIC/LINE Input Module (NRS 90217)

This 2-channel audio input module is meant for the connection of external audio sources, like microphones, mixers, etc. Both channels are furnished with XLRF-type connectors. The module can be installed into slot 1 and slot 2.

The sensitivity of the MIC / LINE inputs can be adjusted in a wide range. The internal MIC / LINE switches (PADs) provide 30 dB attenuation. The separate GAIN-controls for each channel provide additional control in a range of 40 dB. The MIC / LINE inputs are electronically balanced and can be retrofitted with transformers. Phantom power can be switched via jumper setting. If necessary, compressors / limiters can also be incorporated in the audio paths via jumpers.
