Low Power  1 Watt FM Transmitter

1U 1watt transmitter
The TX1 one-watt FM transmitter is ideally suited for micro power radio stations, real estate advertising, lab testing and other applications that demand Broadcast quality. And as an integrated single box solution, it’s an affordable alternative incorporating the exciter, RF. amplifier, power supply, stereo encoder and audio limiter.
 
Designed for pristine audio quality and unsurpassed reliability, thousands of Broadcast’s FM transmitters are operating trouble-free in some of the world’s most remote installations. The TX1 runs cool without an internal fan. With comprehensive features and creative design, the TX1 is exceptional value for those who are on a budget but don’t want to compromise on performance.
 
All Broadcast FM transmitters are loaded with features, such as a configurable compressor/limiter and front-panel LCD control interface. Underlying architecture includes a unique dual-loop Virtual VFO exciter, ultra-low distortion modulator and high performance stereo encoder integrated into a great performing, highly stable FM transmission system. Developed for global use, the TX1 is frequency agile and complies with all applicable CE, FCC and EU regulations.
 
The Virtual VFO dual loop PLL system allows perfect audio flatness to below 10 Hz. AFC bounce and modulator overshoot are things of the pass. Low bass can be achieved without distortion and overshoots, yet with greater stereo separation.
 
Fixed at one-watt output power, the TX1’s limiter and stereo encoder can be switched in and out of circuit. The rear panel contains XLR balanced inputs with input level controls, BNC for multiplex output from the internal digital stereo generator, BNC for multiplex input to the exciter for loop through operation and external processor input. RF output is via an N-Type socket.
