BELAR FMRR-1A FM REBROADCAST RECEIVER

DESCRIPTION

The Belar FMRR-1A FM Rebroadcast Receiver is a crystal-controlled, fixed-frequency receiver designed for rebroadcasting and other applications that require accurate FM reception and composite output. The FMRR-1A features the same sophisticated, multistage filter as in the RFA-1A and RFA-4 to ensure the highest possible performance.

The precision demodulator features two buffered 75 ohm composite (BNC) outputs and a 600 ohm, balanced (XLR) output suitable for rebroadcast of mono, stereo, and SCA signals.
