Wireless IFB (interruptible fold back) systems 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 R1a receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate.

The receiver is housed in a rugged machined aluminum package. An optional spring-loaded belt clip (shown at right) provides a secure mounting on a wide variety of belts, pockets and fabrics. The belt clip is removable to reduce its size and allow mounting into other types of bags and belt worn mounting systems common in field production.

Firmware Version 4

New IFBR1a receivers in the UHF blocks shipping from the factory already have this new firmware installed. If users with older units wish to have the new firmware installed at the factory via the Parts & Repair department, the cost is $60 per unit to cover labor and handling.
