Product Description

The Lectrosonics R1a Wireless IFB (interruptible fold back) system is 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 R1a receiver is housed in a rugged machined aluminum package. A spring-loaded belt clip 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.
