The Lectrosonics IFBR1B is a compact bodypack IFB receiver featuring a removable, rechargeable battery. The receiver is compatible with IFBT4 transmitters, as long as there is frequency band overlap between the components, creating a wireless IFB (interruptible fold back) system to facilitate talent cueing and crew communications in broadcast and motion picture production.
The receiver will run for up to eight hours on the included rechargable LB-50 lithium-ion battery and the unit's LED will change from green to red to warn you when power is low. The updated, all-metal battery door assembly is easier to operate and prevents accidental openings.
The lightweight IFBR1B offers a compact, rugged machined-aluminum chassis with rounded edges, making it comfortable to wear and easy to conceal. A simple power/volume knob and intuitve controls with an LCD screen keep operation simple. 10 presets are available, allowing you to store frequencies in memory, even when the battery is removed, for quick setup on set.
The standard 3.5mm output can drive a wide variety of earbuds, headphones, and induction loops—from 16 to 600 ohms—at substantial volumes. Mono earpieces are automatically accommodated with no loss of audio output or battery life. The included wire belt clip makes it easy to secure the receiver to clothing.
