DEVICE DESCRIPTIONS

5.1.9MIC/LINE + Paging Station Module (NRS 90234)

This 2-channel audio input module is meant for the connection of DPC 4000 Series paging stations and other external audio sources. The RJ-45 socket of channel A allows the connection of up to 4 microphone terminals plus paging station extensions. The MIC / LINE input of channel B is furnished through an XLRF-type connector allowing the connection of microphones, mixers and other audio signal sources. The module can be installed into slot 1 and slot 2.

Next to the electronically balanced audio input, the DPC 4000 input connector provides a serial RS-485 interface and the power supply for the connected paging consoles (see also pin-assignment of the RJ-45 connector). The paging stations' power supply employs an electronic, programmable fuse, through which the maximum output current can be matched to meet actual system accommodations.

The MIC / LINE input employs an internal switch (PAD) providing 30 dB of attenuation. The GAIN-control located on the appliance's rear panel offers additional control in a range of 40 dB. The input is electronically balanced and prepared for retrofitting a transformer. Phantom power

can be switched via jumper. If necessary, a compressor /

figure 5.22 MIC/LINE + paging station module (NRS 90234)

limiter circuit can be incorporated in the audio path.

 

Input channels can be switched separately to the monitor

 

bus and you can listen to the signal via headphones or

 

loudspeaker, either which being connected to the monitor

 

output. Automatic pilot tone surveillance of the entire

 

input stage is integrated as well.

 

Note: When connecting several paging consoles to a single input, please keep in mind that line interruption or short-circuit can cause malfunction of several or even all paging stations of that specific line. In emergency alert installation, connecting security-related consoles to individual inputs is therefore of major importance.
