MM806 Modulation Monitor & Agile Video Demodulator
The Drake MM806 Modulation Monitor is a professional quality agile television demodulator with video and audio metering that demodulates any VHF, UHF, or CATV channel (54 through 806 MHz). The MM806 may be added to any headend installation to select and monitor any NTSC channel to allow setup of video and audio levels.
- Ensures correct and consistent audio and video modulation levels from channel to channel for your entire headend system.
- Synthesized reception of off-air TV channels 2 through 69, and CATV channels 2 through 125; selection set by a convenient front panel push wheel switch.
- Two modulation meters are located on the front panel for ease of operation and provide readout of video modulation and audio deviation percentages.
- Nominal 1.0 Vp-p standard negative sync video output.
- Made with pride in the U.S.A.
