500W CZH Compact FM Stereo Transmitter

500W Compact FM Stereo 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 500W FM transmitters.Also it is low cost and small size.

2. All-digital technologies DSP+DDS
3.Built-in audio signal limiter
4.Analog and digital(AES/EBU)audio signal input directly
5.AGC circuit to keep the Output Power stability
6.Big LCD display all the parameters in real time
7.Communication Interface by RS232 for remote
8.Five kinds of protections for the security
9.Stainless steel cabinet
10.Easy to upgrade to synchronized transmitter

11.Compact structure
