Clear-Com PIC-4000B IFB Controller

Description

The Clear Com PIC4000B IFB Program Interrupt Controller contains audio and switching circuitry for selecting 1 of 2 program signals, routing the signals to 4 independent talent channels and interrupting, with variable program attenuation, the signals from 1 or more control points. This unit contains the circuitry for selecting one of two program sources, sending the program to the IFB channels, and interrupting it via the Talent Control Station. Each IFB Controller handles up to four talent receivers, and has inputs for two program sources. It contains the circuitry for selecting one of the two program sources, sending the program to the IFB channels, and interrupting it – with variable attenuation – via the talent access stations. Its four separate outputs provide discrete, interruptible IFB lines to either monaural TR-50 talent receivers or stereo/split-feed TR-532 talent receivers (one side is interrupt, and the other non-interrupt).
All audio signals, plus DC power, are sent to the talent receivers via 3-pin XLR connectors and standard mic cable. The PIC-4000B requires 30 VDC power from a Clear-Com intercom main station or power supply.
