Used Lectrosonics IFBR1B Receivers in good cosmetic and technical condition. Minor casing wear on the aluminum edges from standard production use. LCD screen, side membrane buttons, top volume knob, 3.5mm jack, and battery door are clean and fully operational.  One Audio Level Knob Missing 

Testing: Bench-tested. Verified clean audio output, 10-preset memory storage, pilot tone squelch, LCD screen navigation, and LB-50 battery charging/contacts. 

Pulled directly from a professional, climate-controlled, smoke-free corporate broadcast facility. All units have been tested, factory reset, and are running stable firmware. Expect minor cosmetic rack-wear/scuffs on the outer casing, but front panels and technical functionality are excellent.

Key Features & Specifications 

• Ultra-Compact Machined Aluminum Build: Significantly smaller and lighter than legacy IFBR1a units (weighs just 3.4 oz with battery), designed for discrete talent cueing and director monitoring. 
• 10 Programmable Memory Presets: Built-in LCD menu screen allows quick programming and instant recall of up to 10 stored frequencies. 
• 8+ Hour Rechargeable Battery Life: Powered by a removable LB-50 3.6V Lithium-Ion battery for full production days. Includes an attached hinged battery door. 
• Headphone Cable Antenna System: Ingeniously uses the connected headphone/earpiece cord as its receiving antenna, eliminating external whip antennas. 
• Universal 3.5mm Output: Drives earbuds, studio headphones, or induction neck loops (16 to 600 Ohms) at substantial output levels. Automatically accommodates mono or stereo earpieces without power loss. 
• Pilot Tone Squelch Control: Supersonic pilot tone squelch prevents audio pops, hiss, or noise bursts when the transmitter is turned off.
