The DMM806 is a professional quality agile television channel demodulator that provides an audio and video output from any VHF, UHF or CATV channel (54 to 806MHz). The modular design of DMM 806 permits convenient pairing with a Drake mini-rack video modulator to perform off-air or CATV channel processing. The desired off-air VHF or UHF television channel from 2 through 69 or CATV channel from 2 through 125 is selected by a front panel push wheel switch and associated slide switch. The DMM 806 provides a standard negative sync video output at a nominal level of 1Vp-p and an audio output signal that is level adjustable from approximately 0.5 to 1.5Vp-p with a front panel control. As previously described, channel selection switches and audio output level control are located on front panel. The RF input is through an F type connector located on rear panel. The rear panel video output is also an F type connector. The audio output is through a rear panel RCA type phono connector. The unit is powered by a compatible Drake mini-rack power supply module.
