50 Watt Professional Broadcasting FM Transmitter




50W FM Stereo Broadcasting Transmitter with Audio Processing Front Panel


Description

This transmitter is the little brother to our 100 watt transmitter. Using a 150W transistor only running at 50 watts gives it reliability and dependability beyond all imagination. It's super silent and can installed in a live mic studio. The stereo version with audio limiting and processing complies with worldwide and international regulatory standards. With a high gain antenna radiated power levels of more that 100 watts EIRP are easily achievable

The stereo version also has the option of MPX input should you wish to connect the unit to external processing such as Optimod, Inovonics, Breakaway, StereoTool etc.

The frequency, power level and deviation is easy to set using the integral frequency counter and controls on the underside panel. More information on this in the user manuals at Stereo with Audio Processing Version and MPX Composite Input Version
