BW Broadcast TX50 V3 FM Transmitter

The BW Broadcast TX50 V3 is an advanced 50W FM transmitter ideal for LPFM stations, community radio, emergency broadcasts, military applications or as a reliable backup transmitter for national broadcasters. This transmitter offers excellent sound quality thanks to its integrated multi-band DSPX audio processor, eliminating the need for a separate processor and making your station sound great right out of the box.

Features and Functionalities

With a DDS exciter and ultra-low distortion modulator, the TX 50 V3 takes the legendary reliability and purity of previous models to the next level. The built-in Web-based control platform provides easy access to settings and monitoring, including e-mail alerts, SNMP monitoring, silence detection and advanced alarms. These features provide peace of mind and save time by quickly identifying and resolving problems.

The TX 50 V3 features a standard, configurable parallel GPI/O interface for integration with your station control equipment. This allows backup audio or backup transmitters to be turned on automatically in case of problems.
