The Portacom Model PGM-100 Program-in Audio-out Module is a two channel, Program Insertion Station and is part of the PortaCom intercom system. It is in a package similar to the B3-100 Branch Box. The PGM-100 provides a means to insert program audio onto the intercom line. A switch on the PGM-100 selects which channel the program audio is inserted onto (Channel A or Channel B). A level control sets the audio level on the intercom line. The PGM-100 also allows for audio-out/intercom-out operation.
