CT-FMM-76 - Overview

The CableTronix CT-FMM is a professional quality fixed channel micro modulator providing an audio and video modulated RF carrier from 54 to 806 MHz on any CATV channel from 2 to 125. Any standard video source
can be used, including satellite receivers, demodulators, VCRs, laser/DVD players, and TV/security cameras.

The CT-FMM employs highly stable synthesized frequency control. Setup and adjustments are easy and straightforward taking advantage of the unit's front panel access to all level controls. Channel frequency information with FCC offsets is programmed into each unit at the factory.

The CT-FMM meets or exceeds government regulatory requirements, including FCC group delay pre-distortion for color transmission, and FCC Docket 21006 aeronautical offset requirements
