X.DA-5
5 kW AM Transmitter5 kW AM transmitter from the X.DA series for medium-power broadcasters. Redundant modular architecture with independent PB-1000W power modules. DDS carrier generation, Class D PWM modulation, and local/remote control via RJ-45 Ethernet. Available in single-phase or three-phase configurations.
The X.DA-5 is a 5 kW solid-state AM transmitter suited to medium-power regional broadcasters needing reliable coverage over hundreds of kilometers. The modular design with six independent 1 kW power stages simplifies corrective maintenance: when a module fails it is identified and replaced individually without specialist tools, minimizing off-air time. DDS carrier generation, Class D PWM modulation, and built-in Ethernet remote control are standard on every unit. HD Radio® and DRM compatibility makes the X.DA-5 a future-ready platform as AM digital broadcasting adoption grows across medium wave.
