The TX25 (3 to 25 watt) FM transmitter is ideally suited for low-power radio stations that demand BW Broadcast quality. An integrated single box solution incorporating the exciter, RF amplifier, power supply, stereo encoder and audio limiter, the TX25 can also serve as an exciter for driving RF amplifiers. This version of the TX25 is custom designed for the Japanese band of 76-90MHz.
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 is 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 is frequency agile and complies with all applicable CE, FCC and EU regulations.
The power amplifier in the TX25 is 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 pass. Low bass can be achieved without distortion and overshoots, yet with greater stereo separation.
The TX25 is 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. The transmitter can also be supplied with an FSK ID keyer input for use in translator applications.
