Specifications:Professional for FM Station

Product introduction:ZHC618F-30W/100W FM Synchronous Transmitter is a new generation of digital synchronous exciter.

ZHC618F-30W/100W FM Synchronous Transmitter

ZHC618F-30W/100W FM Synchronous Transmitter is a new generation of digital synchronous exciter. It is sent directly to synchronous satellite receiver digital audio signal filtering, pre-emphasis, delay, pilot generator, such as a full stereo coding digital processing, and then using direct digital synthesis technology to modulate signal output, GPS numerals frequency converter synchronization for the entire network.



● Hearing similar to CD

● All-digital technologies DSP+DDS

● Built-in audio signal limiter

● Analog and digital (AES/EBU) audio signal input directly.

AGC circuit can keep the Output Power stability.

● Big LCD display all the parameters in real time.

● Communication Interface by TCP/IP; CAN; RS232 for remote

● Five kinds of protections for the security

● Stainless steel cabinet
