100W FM synchronous exciter

Model:ZHC618D-100W

Specifications:100W

Price:$4900

Introduce: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.
