Professional Broadcast FM Transmitter 50W series is a profesional FM stereo/Mono broadcasting transmitter. The advanced digital technologies,Digital Signal Processor(DSP), 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.
More than that, the RS-CM1500W FM transmitter is now gradually showing its high-quality characteristics to the world, especially in the radio station equipment market.
Professional Broadcast FM Transmitter 50W
This Fm Stereo Transmitter, using advance modulation system and Phase Lock Loop to control a steady frequency when transmitting.
Brand new 50W FM Transmitter is a professional Fm Transmitter newly released. It’s featured by one button control for all functions. It has - VSWR protection, temperature protection, RDS port, electronic volume adjusting, equipped with low pass filters. It’s applicable in many places, such as stadium, county radio station, community radio station, motel, public square, church, theater etc.
To optimize to the maximum the price the FM Transmitter is available in two version. The Stereo Coder can be easy upgraded on site also after the first installation.

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 50W Fm Transmitter is continuously adjustable from 0-50 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w...50w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs
