FM SERIES
 
The FM-800 (mono) and FM-850 (stereo/mono) are professional grade FM 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 exiter 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-800 and FM-850 our top-of-the-line transmitters, favored by many sound contractors and audio professionnals.

BEWARE OF CONTENT OF THIS WEBSITE: SOURCEFMTRANSMITTER.COM

This website displays false statements regarding the FCC certification / legality of many FM transmitters including our MS-100.  Please be assured that our MS Series of high quality FM transmitters are FCC part 15 certified and perfectly legal to use in the USA.  Furthermore, sourcefmtransmitter.com also advises potential customers not to buy many models of transmitters (including our MS series), under those false statements.  Instead, it emphasizes one or two products, including their own brand which, ironically, is not recommended by many FM transmitters forums.

We sincerely believe that our MS Series of transmitters are the best FCC part 15 FM transmitters in the market, and no other product even comes close in terms of RF performances, sound quality, reliability and longevity.  Yes, they cost more, but they are well worth it.
