Pico Macom PCFM User manual

The Pico Macom PCFM is a frequency agile professional re-broadcast grade,
microprocessor controlled Stereo/Mono Audio Modulator. Its phase-locked
loop frequency control and sharp two-stage bandpass filtering minimize adja-
cent channel interference and assures accurate and spurious free output. The
PCFM provides up to 35dBmV output across the FM band (88-108 MHz). The
unit is easily tuned by using channel up/down buttons and the digital display
located on the front panel. Designed specifically for commercial installations,
the PCFM provides superior signal-to-noise ratio, discrete left-and-right audio
signal separation, and enhanced dynamic range. Switchable mono/stereo
capability provides FM transmission versatility. The modulator is shipped with
all internal adjustments preset. Pico Macom backs up this product with its
industry leading 5-year limited warranty.
