The Clear-Com program interrupt/IFB system is designed for all broadcast and teleproduction applications. It may be used as a stand-alone system or be fully integrated into an intercom network. The system consists of one or more IFB Controllers, Talent Access Stations, Talent Receivers, an intercom power supply, and interconnect cable. During production taping or airing, the talent – commentators, sportscasters, announcers, musicians, and so on – frequently need to monitor program audio and also hear cues from the director. Clear-Com's IFB system allows talent to monitor the ongoing program, while permitting directors and producers to interrupt or dip the program audio to address them. The IFB system transmits one or two program audio signals to individual talent receivers via standard, two-conductor shielded microphone cable. It permits multiple intercom station or “talent access” operators to interrupt the program and cue talent. The system's virtually unlimited expansion capabilities permit up to 50 talent access locations and up to 96 talent receivers.
