The R.L. Drake DMM 806 is a professional
quality agile television channel demodulator
that provides an audio and video output from
any VHF, UHF, or CATV channel
(54 - 806 MHz). The modular design of the
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 pushwheel switch and associated slide
switch. The DMM 806 provides a standard
negative sync video output at a nominal level
of 1 Vp-p, and an audio output signal that is
level adjustable from approximately 0.5 to
1.5 Vp-p with a front panel control.
As previously described, channel selection
switches and audio output level control are
located on the front panel. The RF Input is
through an “F” type connector located on the
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.
