About Lectrosonics IFBR1B

Discover the advanced IFBR1B-B1 UHF Multi-Frequency Belt-Pack IFB Receiver with Charger, a high-tech solution for professional audio and video applications. This sophisticated device is an integral part of wireless IFB (interruptible fold back) systems, commonly used for talent cueing and crew communications in broadcast and motion picture production.

This innovative receiver is not only user-friendly but also offers exceptional performance, living up to the high standards set by all of Lectrosonics' IFB products. Despite its compact size, it utilizes +/-20 kHz FM deviation for efficient bandwidth use and features compandor noise reduction circuitry, ensuring an excellent signal-to-noise ratio.

The IFBR1B-B1 receiver is equipped with a supersonic Pilot Tone signal that controls the audio output squelch, maintaining silence when no transmitter signal is received. The incoming RF signal undergoes filtration and amplification before being mixed down to the IF frequency by a microprocessor-controlled synthesizer.

Designed for versatility, this receiver automatically accommodates a monaural earpiece connection without any loss of audio output power or battery life. The headphone cable doubles as the receiving antenna, and the receiver can drive a wide variety of earbuds, headphones, and induction neck loops, accommodating loads from 16 Ohms to 600 Ohms.

Battery installation is a breeze with an attached sliding door, and the receiver operates on a single 3.6 V rechargeable LB50 Li-ion battery, providing approximately eight hours of operation per charge. An LED indicator changes color from green to red as the battery voltage declines, giving ample warning before operation ceases.

The IFBR1B-B1 receiver is housed in a rugged machined aluminum package for durability. A wire belt clip is included for secure mounting on a wide variety of belts, pockets, and fabrics. Plus, a USB port is conveniently located inside the battery door for easy firmware updates in the field. Experience the difference with the IFBR1B-B1 UHF Multi-Frequency Belt-Pack IFB Receiver with Charger, a testament to Lectrosonics' commitment to quality and reliability.
