The IFBR1B next-generation receiver unit is nearly half the size and weight of the industry-standard IFBR1A receiver that it is replacing and uses a slim 3.7V LB-50 rechargeable lithium ion battery instead of the archaic 9V type. The new IFBR1B is fully compatible with the existing line of IFBT4 transmitters, so that adding the convenience and new features of the IFBR1B receivers to existing Lectrosonics IFB systems is quick and easy. With a backlit LCD and membrane buttons, the new receiver is easy to set up and use, offering 10 presets which are easily programmable from the front panel.
Five tuning ranges are available for the new IFBR1B receiver: the VHF version (red knob) covers 174-216 MHz, the A1 (470-537 MHz), B1 (537-614 MHz) and C1 (614-692 MHz) versions (blue knob) cover the UHF TV frequencies for most countries, and the 941 Band version (black knob) covers the North American license-only 941-960 MHz range. Future firmware updates can be installed in the IFBR1B in the field via the USB jack on the bottom of the unit. The IFBR1B comes standard with a wire belt clip for light weight and easy placement. An optional “clamp” style belt clip, part number IFBR1BBCSL, is also available, and easily installed with two small screws.
The system’s new companion dock charging system, the CHSIFBR1B, is capable of charging up to four receivers or four batteries in any combination. The charging dock can be also be ganged in groups of up to four, powered by a single power supply, allowing charging any combination of up of to 16 units or 16 batteries

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 IFBR1B receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate. Despite its tiny size, the new IFBR1B receiver offers excellent performance on par with all of Lectrosonics’ IFB products.
The IFBR1B is housed in a rugged aluminum package. A wire beltclip is included and provides a secure mounting on a wide variety of belts, pockets and fabrics.
