FMT25 Mono/Stereo
25 Watt FM Transmitter

The Linear Broadcast FMT25 FM Transmitter is designed to fill the needs of the narrowcaster requiring high performance and reliability at a cost effective price. The FMT25 is self-contained in a 2RU rack case and provide fully adjustable power output  up to 25 Watts and a user-programmable Phase Locked Loop frequency via simple and accessible rotary switches.  It has a multi-function LCD meter which allows metering of forward and reverse power, audio levels and power supply current and voltage. As with nearly all our FM transmitters, a stereo encoder can be added inside the FMT25 if stereo broadcast is required and an external encoder is not being used.
