FM Systems FMT615C Stereo Multiplex Transmitter

The FMT615C is equipped to accept audio and modulate the program to the 88-108 MHz F,M. stereo broadcast band. The audio may be true stereo (separate Left and Right channels) or mono, or synthesized (within the FMT615C) to stereo, as selected by a field-programmable jumper jack within the unit. In addition to the F.M. band output, there is a composite stereo audio output to feed an additional microwave modulator to deliver the stereo program to a remote cable system. There is also a mono output to feed audio to the T.V. audio modulator.

 

The RF output frequency of these units, like other F M Systems products, is adjustable in the field without changing crystals. This state-of-the-art design uses a master crystal oscillator and a programmable phase-lock-loop (PLL) system to precisely set the output to any standard frequency in the FM Broad- cast Band. Other frequencies outside the 88-108 MHz Band are available upon special request.
