500 Watt Frequency Modulation Transmitter

500 Watt FM transmitteris a compact FM stereo broadcasting transmitters. The advanced digital technologies, Digital Signal Processor (DSP) and Digital Direct Synthesizer (DDS), are used in the transmitters to get little size, high performance and high reliability. They are widely used for professional radio stations to transmit high quality FM radio programs.

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.

OUTSTANDING FEATURES:
1) OVERHEAT PROTECTION: The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range. 
2) OVER SWR PROTECTION: SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile. 
3) FAN ERROR ALARM When the fan stops running, the alarm message will be displayed on the screen. 
4) ADJUSTABLE POWER OUTPUT The RF out of this 500w FM transmitter is continuously adjustable from 0-500 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w...50w...100w...500w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs
