The Belar FMRR-4 Frequency Agile FM Rebroadcast Receiver is a microprocessor controlled, tunable receiver designed for rebroadcasting and other applications that require accurate FM reception and composite output.
The FMRR-4 features 10 memory locations for one-button access to 10 stations with call letters. Direct dial of any standard FM frequency is also possible, and UP/DOWN buttons are included.
The station's call letters can be programmed into the display with the frequency for quick and easy reference. A sophisticated, multistage filter ensures 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.
