The Lectrosonics IFBR1B receiver is compatible with IFBT4 transmitters, as long as there is frequency band overlap between the components, creating a wireless IFB (interruptible foldback) system to facilitate talent cueing and crew communications in broadcast and motion picture production. The Lectrosonics IFBR1B will run for up to eight hours on the included rechargeable LB-50 lithium-ion battery and the unit's LED will change from green to red to warn you when power is low. Also, the Lectrosonics IFBR1B is lightweight that can offer a compact, rugged machined-aluminum chassis with rounded edges, making it comfortable to wear and easy to conceal. It has a simple power/volume knob and intuitive controls with an LCD screen keep operation simple. The 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.
