Introduction: The transmitter adopts a simple design concept, and the 500W FM stereo transmitter exciter and power amplifier, output filter, switching power supply, etc. are installed in a 2U high 19-inch standard chassis, which reduces the parts between ordinary transmitters. The connection cable is more reliable and easier to operate. Using the latest DSP + DDS full digital technology stereo frequency exciter, the machine's technical indicators are unparalleled, reaching close to CD sound quality auditory effects. It uses a large radiator and two German original high-speed, long-life fans to ensure that the transmitter works at a reliable low temperature. Adopt Taiwan's original Mingwei wide range switching power supply. High reliability, high performance, easy operation and low price. Features: 1.Simple design, integrated structure, high reliability, easy operation 2. Full-process digital processing (DSP+DDS) to achieve a perfect auditory effect close to CD sound quality 3. Analog audio and digital audio (AES/EBU) can be input simultaneously, digital audio is preferred 4. With TCP / IP, SMS cat, RS232 communication interface, can use computer management and monitoring 5.
