Wireless IFB (interruptible fold back) systems operate between 537.600 and 767.900MHz. They are used for talent cueing and crew communications
in broadcast and motion picture production. In other cases, the IFB system is used by directors and other management to monitor program audio during a production. The IFB PRC-2 receiver provides
simplicity and flexibility in a package that is intuitive for untrained users to operate. Wireless IFB uses +/-20 kHz FM deviation for efficient use of the bandwidth, with compandor noise
reduction circuitry for an excellent signal to noise ratio.
