50W Cable Broadcast Radio Transmitter 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.
This Fm Stereo Transmitter, using advance modulation system and Phase Lock Loop to control a steady frequency when transmitting.
New invented low noise system is used to reduce the noise level during broadcasting time. A digital stereo system is used andcontrol the stereo separation at great condition. with a high gain antenna, it can easy broadcast anywhere you want, home, apartment, church, school, club, camping, backyard, resident village. This Broadcast Package is plug and Play design, very easy to use, as you could see it at instant. so you really could enjoy the stereo transmitter!
The transmission range depends on many factors. The true distance is based on the antenna installing height, antenna gain, using environment like building and other obstructions, sensitivity of the receiver, antenna of the receiver. Installing antenna more high and using in the countryside, the distance will much more far.

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
