TABLE OF CONTENTS
GENERAL DESCRIPTION
The modulator accepts standard (sync negative) polarity
video at a 0.7 -1.5 Vpp level. A high quality IF SAW filter
eliminates adjacent channel interference.
IF loop-through capability in the VM2551 supplies an IF
output prior to channel conversion. This feature provides
the capability to replace the standard internally generated
IF output with an alternate source of composite IF, or
allows insertion of IF scrambling equipment.
The internally generated aural carrier may be disabled by
moving an internal jumper and an external 4.5 MHz
carrier can can be inserted via the rear panel 4.5 MHz
input.
These features, combined with a carefully designed low
intermodulation output stage, provide reliable operation
in a densely crowded SMATV or cable environment.

The Drake VM2551 Video Modulator is a vestigial
sideband unit with synthesized visual and audio carriers.
The VM2551 is designed to accept video and audio
baseband signals from a satellite receiver, video server,
VCR, camera, or similar equipment. Front panel video
and audio level controls and overmodulation indicators
permit setting the proper modulation levels. Synthesized
operation provides complete frequency agility, allowing
front panel selection of any standard, HRC, or IRC, CATV
channel from 2 to 78 and channels 95-99 or OFF AIR TV
channels 2-27. FCC required channel frequency offsets,
for aeronautical channels of zero, +12.5 kHz, or +25 kHz
are selected automatically and offset positive when
offsets are required.

F10, F11 - CHannel Select Buttons
Press F10 to decrement the selected channel settings.
Press F11 to advance to the next highest numbered

F12 - RF OUTPUT LEVEL
This screwdriver adjustment permits decreasing the RF
output level a minimum of 10 dB below its specified
output level as the control is rotated counterclockwise.
The maximum output level of +55 dBmV is set with the
adjustment approximately fully clockwise.
NOTE: If an output level of less than +45 dBmV is
required, add an attenuator of the appropriate value at
the modulator output and operate the modulator at the
highest practical level (not exceeding 55 dBmV).
Example: For an output level of +35 dBmV, add a 12 dB
or 18 dB attenuator pad to the modulator output and set
the output level.
F13- OUTPUT
This type "F" connector provides a test monitor output that
is nominally 30 dB below the main rear panel RF output
level.

F1 - A/V RATIO Control
This screwdriver adjustment varies the level of the aural
carrier over a range from 12 to 18 dB below the visual
carrier. The aural carrier should be adjusted to
approximately 15 dB below the visual carrier (normal
operation).
F2, F3 - AUDIO LEVEL Control &
AudioOvermodulationLED
The setting of this screwdriver adjustment determines the
peak aural carrier deviation. Clockwise rotation in-
creases the carrier deviation. After installing the unit, and
with an audio source connected, adjust for 25 kHz
deviation by advancing the Audio Level control, F2, until
the Audio Overmodulation LED, F3, begins to illuminate.
Monitor for a few minutes to assure that maximum volume
of the audio source program does not cause an
overmodulation condition.
F4, F5 - VIDEO LEVEL Control &
VideoOvermodulationLED
The setting of this screwdriver adjustment determines the
video modulation level. Clockwise rotation increases the
modulation depth. After installing the unit, and with the
desired nominal 1 Volt P-P video source connected,
adjust the VIDEO LEVEL control F4 for the correct
percentage of modulation (87.5%). This setting will be
achieved when the Video Overmodulation LED, F5, just
barely illuminates. Advance video level until F5
illuminates and then back off until F5 just extinguishes.
F6 - CHANNEL Display
This is the 3 digit display which displays the selected
output channel. If the modulator is set to output off-air
broadcast frequencies (the ANT setting) the channel
number is preceded by an A. Off-air channels will display
as A2 through A27. When the CATV channel plan is
selected, a numeric 3 digit EIA channel number is
displayed.

R1 - RF OUTPUT
This is the modulator output.
R2 - IF IN Connector
This is the composite IF input to the up converter circuits.
The composite IF has both the aural and visual IF
combined. This connection is normally cabled directly
from the “COMPOSITE IF OUT” connector (See R3). This
external IF loop allows the use of accessories such as
scramblers or alternate video sources.
R3 - IF OUT Connector
This is the composite IF output from the IF circuits. The
composite IF provides a vestigial sideband filtered visual
carrier at 45.75 MHz combined with a level controlled
(-15 dBc typical) aural carrier at 41.25 MHz. This connec-
tion is normally cabled directly to the “COMPOSITE IF IN”
connector (See R2). The video carrier output level is
+40 dBmV.
R4 - VIDEO INPUT Connector
This is the baseband video input to the IF circuits. This
input accepts baseband through 4.2 MHz video at levels
from 0.7 Vp-p to 1.5 Vp-p.
R5 - AUDIO INPUT Connector
This is an unbalanced audio input to the IF circuits. This
“RCA” (phono) connector input accepts 40 Hz through
15 kHz audio at a nominal level of 250 mV RMS
(approximately -10 dBu). Input impedance is 10K Ohms.
R6 - 4.5 MHz INPUT
To use this input, remove the top cover of the modulator
and move jumper J2 to the ON position. Input 4.5 MHz at
R6 at a level of +37 dBmV.
R7 - 600 W Convenience Outlet
This outlet is unfused and must be limited to a 5A or 600
W load at 120 VAC.
R8 - LINE CORD
Connect the 3 wire IEC line cord to this connector.
Connect to a nominal 115 VAC ±10%, 60 Hz source. Do
not defeat the safety purpose of the ground pin on the line
cord plug.
R9 - FUSE
To access the fuse, unplug line cord from the socket R8.
Pull out on the tab on the upper side of the fuse
holder assembly.

RACK MOUNTING
Adequate ventilation is very important in multichannel
installations. Units should be spaced apart by at least
one panel height wherever possible, and some air
movement is advisable in enclosed rack cabinets.
Excessive heat will shorten component life and modulator
performance will be degraded without proper cooling.
USE WITH A STEREO ENCODER
An external BTSC stereo encoder may be used with the
VM2551. To sett the VM2551 for a flat audio response
that will accept the BTSC composite stereo input - remove
the top cover of the VM2551. Observing the PCB that
contians the Audio, Video, A/V Ratio, and other compo-
nents, locate the small slide switch - SW2. Set switch
SW2 to the Pre-emphasis OFF position. The factory
default setting is Pre-emphasis ON - for mono operation.
CONNECTIONS AND CONTROLS
All connections to and from the VM2551 are made
through the rear panel. Additional channels can be
added by using additional VM2551 modulators and either
multi-port combiners or combinations of two-port
combiners.
INSTALLATIONNOTES
Level adjustment provides optimum performance in
multichannel installations. The modulator outputs should
be checked periodically to maintain a ±1 dB variation of
adjacent channel carriers. Aural/Visual (A/V) ratios
should be held to -15 dB or less. The output 'RF Level'
and 'A/V Ratio' controls are used respectively to make
these adjustments. If an output level of less than
+40 dBmV is required, add an attenuator of the
appropriate value to the modulator output.
