500W FM TX

 

 

500 Watt FM Stereo Transmitter

Model : ZHC-500W-TX
Product Name : 500W FM Transmitter
Price : $3400 USD
Description:

Professional 500W FM transmitter All-in-one 19inch 4U cabin Software radio product DSP+DDS CD audio quality Big LCD displays all the parameter Analog and digital (AES/EBU) audio signal input Easy to use.

The transmitter implements a digital FM modulator module as its core, combining a RF power amplifier. DSP & DDS are used to execute all-digital processing, such as digital filtering, pre-emphasis, pilot generation, stereo coding and FM modulation.  AGC circuitry is used to keep the set power stable. High performance and very good reliability has been proved by the large usage of ZHC-500W-TX transmitters.  These transmitters are very low cost and small size.
