Video Distribution Amplifiers
What is a Distribution Amplifier?
A Video Distribution Amplifier, or "DA" takes a single baseband video input signal and generates
copies of that signal to drive multiple outputs. VAC’s DAs are active devices: the output signals are
amplified and buffered, so that the signal quality on any of the outputs does not degrade when additional devices are connected to the DA.
Why Use VAC Video DAs?
VAC is the market leader is delivering exceptionally compact, reliable, and high-quality video distribution amplifiers for broadcast, professional AV, security, military, and manufacturing applications.

Quad DAs
Low-Cost, Compact Multi-DA Brick®
VAC's Quad DA combines four composite video 1X2 distribution amplifiers into a compact, rugged,
and inexpensive package. It is the ideal solution where a small number of video channels are required.
Unlike many multiple DA products, VAC's Quad DA does not require a rackmount; the unit is completely self-contained, and requires only input power (a 12V AC wall transformer is included) to operate.
At only 4.4" by 2.2" by 1.4" the Quad DA is small enough to mount almost anywhere. VAC also offers
rackmount solutions for customers desiring to install multiple ProSeries™ products.

DVRx
Converting analog composite video to digital video has become commonplace in security, presentation, and broadcast systems. Regardless
of the application, an optimized analog video input is essential for efficient and accurate A/D conversion. The DVRx* product line is specifically designed to provide reliable, easy-to-use, and accurate analog video optimization. Quickly set
composite video to RS-170A (NTSC) specifications with the DVRx to ensure optimal A/D converter
performance. The results can be impressive: Smaller file sizes, less distortion, and improved resolution.
Essential for DVR Applications
Unlike an video tape recorder, which simply records the incoming signal to tape, a DVR must first
convert the analog signal to a digital format. When the analog video doesn’t meet the RS-170A specification – either due to transmission line losses, noise, interference, or DC voltages riding on the signal – the A/D conversion process may generate errors that significantly degrade DVR performance.
Problems can include erratic recording, false motion detection, and moderate to sever distortion to the
video picture. VAC’s DVRx can optimize the analog signal to significantly reduce and typically
eliminate many of the problems that cause poor DVR performance.
DVRx Features
• Differential (“humbucking”) 75Ohm input mitigates ground loop interference
• Adjustable gain and EQ compensates for cable losses or low signal levels from the
video source
• AC coupling on the input eliminates DC offsets
• DX Restore circuitry provides correct voltage references to ensure outputs meet
RS-170A spec
• 40 MHz bandwidth is more than sufficient for NTSC quality video
* Patent Pending
Coming Soon… VAC's Auto DVRx! Automatically adjusts gain and
EQ levels for optimum signal quality; front panel display with
menus for selecting automatic or manual operation. NO Back-panel
controls! Call VAC or visit our website for more information.

Legacy™ Series Distribution Amplifiers
Composite Video DAs
MVB/VDA-4
HBVB/VDA
CVB/VDA
CVB/VDA (# 100-0-001): The clamping action of the CVB/VDA corrects for 60 Hz hum, improper DC offset, and
other low frequency interference in the input signal by clamping the output sync-tips to a fixed level. This correction is
effective even if the signal and hum have been transmitted by microwave, satellite or fiber. An adjustable clamp level
allows use with systems that require the sync-tips to be clamped to some level other than -40 IRE (-0.286 volts). The
CVB/VDA provides an adjustable gain range of 0.5X to 2.0X and is designed to clamp properly when the output video
signal is set to 1Vpp (140 IRE).
HBVB/VDA (# 100-0-007): The HBVB/VDA reduces or eliminates hum and herringbone interference resulting from a
ground loop. The unit effectively breaks the ground loop by providing up to 15V peak hum rejection of the input signal.
The unit provides four output signals with adjustable gains. The TRIM adjustment allows the user to maximize the
amount of interference rejection by matching its differential input to the desired quality.
MVB/VDA-4 (# 100-0-016): The MVB/VDA-4 is a battery-operated distribution amplifier with four outputs. The
MVB/VDA provides unity gain outputs, meaning the output signals are the same level as the input signal. This unit can
be powered by the same battery pack as a camera. They can also be powered by truck, van, bench power supply, DC
wall transformer, or a 9V lithium battery (which can last up to 48 hours). By working on a separate battery, the power
line ground line is eliminated thus eliminating any interference caused by ground loops.

Composite Video DAs
VDA-640
HN/VDA
HN/VDA (# 100-0-008): The HN/VDA is a hum/interference rejecting video distribution amplifier with six outputs and
gain control. The trimmable differential input takes advantage of hum and interference rejection by eliminating groundloop noise interference. The gain control also allows the user to set the gain from 0.5X to 2.0X.
VDA-640 (# 100-0-021): The VDA-640 is a six-output loop-thru input, video distribution amplifier with gain. The
loop-thru input allows the original signal to go through unimpeded to other equipment while still allowing other channels with gain control to split up the signal for processing or monitoring. If the loop-thru connector is not connected, a
75 Ohm termination must be present for the VDA-640 to work properly. Each channel has 0.5X to 2.0X of adjustable
gain. 75 Ohm terminators are available for purchase.

Equalizing Composite Video Distribution Amplifiers & Line Amplifier
Equalizing or "EQ" composite video amplifiers incorporate both variable gain and variable EQ to
compensate for signal losses over long coaxial cable runs.
Why Use an Equalizing Amplifier?
Coax cable is ideal for baseband video signal transmission - over relatively short distances. Once
the cable length exceeds 100 to 200 feet, cable losses can noticeably degrade picture quality.
Attenuation over coax cable increases with the frequency, so the loss is not uniform across the
video signal bandwidth. The high frequency loss or "roll-off" in a long cable run decreases video
resolution. Sharp lines become blurry, and contrast is lost. Ghosts may appear along straight lines,
or where there is significant contrast on the original signal. Text is particularly degraded, as both
contrast and resolution are critical to presenting crisp, readable text on a video display.
Because different cable types have different loss characteristics, VAC offers both the Basic Block™
Line Drivers and ProSeries™ EQ DAs in versions optimized for RG-59, RG-6 or 8281 type cable.
The Basic Block EQ Line Amplifier is an ideal solution when only a single output is required.
The ProSeries EQ DA incorporates a 1X4 DA, and a differential input to mitigate ground loop
interference.

SDI Video DA
SDI Line Driver PN: 63-711-101
The multi-standard automatic reclocking SDI line driver is designed to compensate for losses in up to 300m of
high-quality 75 Ohm cable at 270Mb/s. The SDI line driver will automatically recover the embedded clock signal
and retime the data from a SMPTE 259M or SMPTE 344M digital video signal. Additionally it removes high-frequency jitter components, and restores the output voltage swing to 800mVp-p (within +/- 7%). The reclocking
stage may be deactivated via a three-position DIP switch; a disable control for 177Mb/s data rate prevents a false
lock when operating at 270 Mb/s data rates (DVB/ASI).

Input Signal
SDI/DA-LT (# 100-0-018):
The SDI/DA-LT is a Serial
Digital Interface Distribution Amplifier. The unit has a
single loop-thru input and uses a distribution amplifier to
provide two outputs that are the same signal strength as the
input. This is referred to as “unity gain”. The SDI/DA-LT
will work with either 270 Mb/s or 360 Mb/s serial digital
information at 800 mV. The SDI/DA-LT loop-thru feature
allows the original signal to go through unimpeded while
producing two taps to process or monitor the input signal.
If the loop-out feature is not used, a 75 Ohms terminator
must be in place. The SDI/DA-LT ships with a 75 Ohm
terminator and wall transformer.
