[FMZ-500W]: 0-500W FM Transmitter
Professional 500W FM transmitter All-in-one 19inch 3U 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 $
Package: FMZ-500W X1

FMZ-500W FM Transmitter

The transmitter implements digital FM modulator module as its core,combining with RF power amplifier.In the transmitter,DSP&DDS are used to execute all-digital processing,such as digital filtering,pre-emphasis,the generation of pilot frequency,stereo coding and FM modulating.A AGC circuit is used to keep the set power stable.
High performance and very good reliability has been proved by the large usage of ZHC618F-500C transmitters.Also it is low cost and small size.
