VMM806AG and other compatible

The R.L. Drake Video Modulator System is a
professional quality modular headend system
designed to optimize rack space. An
assortment of up to (12) modular units, such as
the fixed channel series of modulators, or agile
modulators, or compatible audio/video products
can be racked alongside a single power supply
in the Drake12 position rack mount. The RMM4
rack mount accepts up to (4) modular units.
The R.L. Drake VMM806AG Audio-Video
Modulator is a high quality, vestigial sideband
unit with synthesized visual and aural carriers.
The frequency agile VMM806AG allows front
panel pushwheel switch selection of standard
CATV channels 2 through 125, or VHF/UHF TV
channels 2 through 69. Aeronautical channels
are offset positive with a tolerance of ±5 kHz as
required by FCC rules.
The heterodyne conversion system, in
conjunction with the use of a SAW filter,
ensures optimum vestigial selectivity for
adjacent channel headends.
An optional FCC predistortion SAW response is
also available for the VMM806AG.
The modulator is designed to accept any
standard audio/video source such as NTSC
video and audio baseband signals from a
satellite receiver, TV camera, videotape
recorder, TV demodulator, or similar signal
source.
The modulator is designed to accept standard
(negative sync) polarity video at 0.6 to 1.5 Vp-p
level. All level controls are located on the front
panel for ease of operation. Output level is
+45 dBmV and is adjustable over a 15 dB
range.
Field-defeatable audio pre-emphasis allows
transmission of BTSC encoded baseband
stereo audio signals using the Drake stereo
encoder. The AUDIO INPUT can also accept a
4.5 MHz audio modulated carrier by changing
internal jumpers.
