DEVICE DESCRIPTIONS

5.1.6 MIC/LINE + 2 AUX Input Module (NRS 90216)

This 2-channel audio input module is meant for the connection of external audio sources of any kind. Channel A employs two switched AUX-inputs with 4 RCA-type connectors (2 x L / R) for CD players, tape decks, tuners, DAT decks, etc. The MIC / LINE-input of channel B is provided through an XLRF-type connector allowing the connection of microphones, mixers and other similar sources. The module can be inserted in slot 1 and slot 2.

Input levels of both AUX-inputs can be separately adjusted via internal potentiometers in a range between – 10 dBu to +12 dBu.

The MIC / LINE-input's sensitivity can also be adjusted through an internal MIC / LINE switch (PAD) providing 30 dB attenuation. The GAIN-control on the appliance's rear panel offers additional control within a range of 40 dB. The MIC / LINE input is electronically balanced and can be retrofitted with a transformer. Phantom power can be switched via a jumper. If necessary, it is also possible to incorporate a compressor / limiter into the audio path via jumper setting.

The input channels can be switched separately to the monitor bus and you can listen to the signal via headphones or loudspeaker, either which is being connected to the monitor output. Automatic pilot tone surveillance of the entire input stage is integrated as well.
