The TX25 (3 to 25 watt) and TX50 (5 to 50 watt) FM transmitters are ideally suited for low-power radio stations that demand BW Broadcast quality. Integrated single box solutions incorporating the exciter, RF amplifier, power supply, stereo encoder and audio limiter, the TX25 and TX50 can also serve as exciters for driving RF amplifiers.
Designed for pristine audio quality and unsurpassed reliability, thousands of BW Broadcast's FM transmitters are operating trouble-free in some of the world's most remote installations. With comprehensive features and creative design, the TX25 and TX50 are exceptional value for those on a budget but don't want to compromise on performance.
All BW 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 TX25 and TX50 are frequency agile and comply with all applicable CE, FCC and EU regulations.
The power amplifiers in the TX25 and TX50 are based on a modern MOSFET device. High power fans draw fresh air through the transmitter's heatsink to keep the transistor and amplifier cool.. Amplifiers are protected from damage by temperature control systems and antenna fault (VSWR) monitoring which react to faults by reducing the output power to a safe operating level, keeping you on air rather than shutting down completely.
The Virtual VFO dual loop PLL system allows perfect audio flatness to below 10 Hz. AFC bounce and modulator overshoot are things of the past. Low bass can be achieved without distortion and overshoots, yet with greater stereo separation.
The TX25 and TX50 are more configurable and flexible than other units in their class. The 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.
An RS232 control and monitor system can be managed from a standard terminal program or BW Broadcast's included Windows application. Both units can also be supplied with an FSK ID keyer input for use in translator applications.
