The Drake FMC1000 FM Stereo Modulator is a high quality audio modulator designed for use in private
and franchised cable systems and permits retransmission of audio broadcasts over cable. Synthesized
operation provides total system flexibility and permits setting the operating frequency in 100 kHz incre-
ments from 88.1 to 107.9 MHz.
The FMC1000 employs multiple audio inputs to allow for both balanced and unbalanced left and right
audio. These features make the FMC1000 an inexpensive solution for competing in today’s cable market.
