LECTROSONICS IFB R1a (Rental)

The Lectrosonics IFBR1a is the belt-pack IFB receiver that has been standard issue on carts and around necks for years. One knob does everything: power, audio level, and pressing it scrolls through stored frequencies. A tricolor LED tells you the battery state at a glance. Simple enough to hand to a director, a producer or talent without a briefing.

Our units are block 24, covering 614.400 to 639.900 MHz with 256 frequencies at 100 kHz spacing. Frequency is set either with the two rotary switches on the side panel or with the scan-and-store function, which finds a clear channel without a computer and keeps it in memory even with the battery out. It works with the Lectrosonics IFBT4 and IFBT1 transmitters, and with Digital Hybrid transmitters in the same block set to IFB mode.
