FM-850 are professional grade stereo FM 1.8 watt transmitters operating in the commercial FM band (87.9 – 107.9 MHz). They are perfect for small community radio stations, campus radio stations, religious radio stations, special events coverage, touristic sites, large stadiums, etc. They can also be used as an FM exciter to drive an RF power amplifier to obtain a greater RF power level. Their outstanding RF and audio performances, ruggedness, reliability, versatility, ease of use and increased RF power level make the FM-850 favored by many sound contractors and audio professionals.
