- The FM-850 is a professional grade mono/stereo FM transmitter operating in the commercial FM broadcast band (87.9 - 107.9MHz/200KHz channel spaching). The FM-850 can be used as a stand alone FM transmitter or as an FM exciter for greater RF power (RF power amplifier required).
- The FM-800 series are one of the easiest available FM transmitters to program and operate, thanks to the latest development in digital programming circuitry. It is now possible to digitally program the frequency and the RF power with accessible direct dial switches on the front panel. Manual tuning or calibration becomes a thing of the past with these FM transmitters.
- The FM-800 series are currently the most affordable, stable and trouble free FM transmitters available on the market today thanks to its new auto-compensation circuitry that will assure optimum RF linearity on a temperature range of -50C to +50C (-58F to +122F).
- The stereo generator of the FM-850 model features a full digital circuitry that allows a stereo separation greater than 45dB. The unit features an incredible carrier frequency tolerance equal to, or greater than 0.0008%.
Decade transmitters are intended for use in low power broadcast stations, community and campus radio but can also be used (where allowed) for multi-lingual conferences, play by play broadcast inside arenas and stadiums (the FM-800 series are able to cover a 42,000 seats stadium when used with good quality FM walkmans at the receiving end). Applications are endless...
