Introduce:ZHC618F-10W is a professional FM stereo/Mono broadcasting transmitter. The advanced digital technologies, Digital Signal Processor (DSP) and Digital Direct Synthesizer (DDS), are used in the transmitters to get little size, high performance and high reliability. They are widely used for professional radio stations to transmit high quality FM radio programs.
