ZHC618F-1000W Compact FM Stereo Transmitter

Overview

This transmitter adopts a simple design concept. The 1KW FM stereo transmitter's exciter and power amplifier, output filter, switching power supply, etc. are installed in a 3U high 19-inch standard chassis, which reduces the common components Connection cable for higher reliability and easier operation.

It’s using the latest DSP + DDS full digital technology of the stereo FM exciter, the technical specifications of the whole machine are unparalleled, achieving close to CD sound quality hearing effect. Large size radiator and 3 original German high-speed, long-life fans are used to ensure that the transmitter works at a reliable low temperature. Uses highly reliable, wide range switching power supplies. The transmitter has high reliability, high performance, easy operation and low price.
