The MIDM is a professional quality agile
audio/video demodulator and is intended
for both CATV and VHF & UHF applica-
tions. The unit is in a “single width” Die-
Cast housing that allows deployment of
up to 12 demodulator units in a MIRC-
12 chassis.
The MIDM demodulates standard CATV,
IRC and HRC channels and is capable
for “Cherry Picking” of CATV channels in
preparation for remodulation. The input
frequency range is agile, allowing selec-
tion of any CATV channel from 54 to 806
MHz. Baseband audio and video are
provided as outputs. It is ideal for off-air
signal processing (audio/video process-
ing and remodulation) applications.
Baseband audio and video are provided
as ouptuts. The MIDM features rock
solid, phase lock loop (PLL) synthesized
frequency control. Agile frequency
selection is accomplished via front panel
channel up/down buttons with a LED
channel readout for easy on-the-fly
channel changes. A channel lockout
mode is also provided to prevent acci-
dental channel changes. Non-volatile
memory maintains the programmed
channel selection in case of power loss.
The MIDM is compatible with any modu-
lators requiring a baseband input, and
can be used in any combination with the
MIPS-12C power supply in a MIRC-12
chassis.
