are members of the R.L. Drake 19" Mini-Rack
Series, 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

VMM860AG, VMM860AS
and other compatible modular units
The heterodyne conversion system, in
conjunction with the use of a SAW filter,
ensures optimum vestigial selectivity for
adjacent channel headends. A FCC
predistortion SAW response is standard.
The modulators are 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 VMM860AS has both a left and
right audio input to accomodate stereo sources.
All level controls are located on the front panel
for ease of operation. Output level is +45
dBmV and is adjustable over a 10 dB range.
On the VMM860AG, an audio pre-emphasis
defeat, rear panel switch allows transmission of
BTSC encoded baseband stereo audio signals
when used with the external Drake MMTS20
stereo encoder. A stereo encoder is built into
the VMM860AS model.
