A Word On Distribution Amplifiers
Distribution amplifiers are used to distribute one source to several acceptors for simultaneous
recording or monitoring of one source, with no discernible signal degradation. They vary in the
number of inputs, looping capability, programming capability, number of outputs, operating format,
bandwidth and input/output coupling. A good quality distribution amplifier amplifies the incoming
signal, pre-compensates the signal for potential losses (resulting from the use of long cables, noisy
source, etc.) and generates several identical buffered and amplified outputs. Often, a signal processor is
inserted between the source and the distribution amplifier for correction and fine-tuning of the source
signal before multiplication, so that all copies are corrected in the same way. The front panels of these
Kramer amplifiers are designed to be simple to operate.

Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from a source to an
acceptor:
Connection cables - Low quality cables are susceptible to interference, they degrade signal quality due
to poor matching and cause elevated noise levels. They should therefore be of the best quality.
Sockets and connectors of the sources and acceptors - So often ignored, they should be of highest
quality, since "Zero Ohm" connection resistance is the target. Sockets and connectors also must match
the required impedance (75ohm in video). Cheap, low quality connectors tend to rust, thus causing
flaws in the signal path.
Amplifying circuitry - Must have quality performance when the desired end result is high linearity,
low distortion and low noise operation.
Distance between sources and acceptors - Plays a major role in the final result. For long distances
(over 15 meters) between sources and acceptors, special measures should be taken in order to avoid
cable losses. These include using higher quality cables or adding line amplifiers.
Interference from neighboring electrical appliances - These can have an adverse effect on signal
quality. Balanced audio lines are less prone to interference, but unbalanced audio should be installed
far from any mains power cables, electric motors, transmitters, etc. even when the cables are shielded.

Optional Accessories
The following Kramer accessories can enhance implementation of your amplifier.
SP-11 - (Video/Audio Processor) can be serially connected between the video/audio source and the
VM amplifier for video and audio control/correction. The machine provides camera control and
luminance/white balance correction. The SP-11 is also capable of performing Composite to Y/C
conversion and bi-directional transcoding. The machine allows full control over the video signal:
Video gain down to full fade, log or linear Definition control, log or linear Contrast control, Color
saturation control, Black Level control, Red, Green and Blue controls and a Screen Splitter control
for “before-after” comparison. The Input switch control is "Audio-follow-Video".
SP-3001 - (Component Video Processor) can be serially connected to the VM amplifier in order to
achieve full control of component video. The SP -3001 has 3 looping Component Video inputs and 9
outputs- three for each component; thus it serves as a Component DA as well. The SP -3001 allows
full control of Gain, Contrast, Definition and black level of the Y channel and individual Gain and
Black level controls of the R-Y and B-Y channels. A Screen Splitter control for "before-after"
comparison is also built in.
VS-2516 - (Programmable Vertical Interval Matrix Switcher) can be serially connected to the VM
amplifier for input switching and source selection. The VS -2516 serves as a 16x16 Composite Video
switcher, as an 8x8 Super Video (YC) switcher, as a 4x4 RGBS or as a 5x5 YUV switcher. It may be
connected to a VS-2216/VS-2616 (16x16 Audio Matrix Switchers) for "Audio follow Video"
applications. The VS -2516 has very low cross talk and wide frequency response, DC coupled
outputs, with RS-232 interface built-in, (software provided), LCD panel read-out, LED status
display, up to 15 setups savable in non-volatile RAM, and is microprocessor controlled with user
programmable settings. It can be easily extended up to 96x96 by using additional machines.
VP-102 (VGA to RGBS Converter) is a full bandwidth VGA to RGBS Converter especially
designed for computer, workstation and presentation applications, and for simplifying computer
graphics distribution. The machine may be installed between a PC and one of the DA's for
conversion between the DB-15 connector type signals, to a signal appropriate to the DA. This is
implemented by using the VP-102 as a converter from VGA/Super - VGA/XGA graphics output to
KRAMER ELECTRONICS LTD.

Red, Green, Blue, Horizontal/Composite sync and Vertical Sync signals available on BNC
connectors. The VP-102 allows the user to select either a Composite or Horizontal sync output and
the Green output either includes Composite sync or is blanked.
SG-11 (Sync-Green Adder/Separator) is used for adding a sync signal to the "GREEN" channel
prior to distribution. The SG-11 interfaces between the two most widely used professional
Component Video formats: RGB with Sync on Green and RGBS. The SG-11 either combines Sync
with Green or splits Green & Sync signal to separate Green and Sync on the BNC connectors.
TP-1 (Video Line Transmitter). If one of the DA outputs is sent over a long distance (100 meter or
more), it is necessary to convert the signal to twisted pair type. The TP-1 sends a color video signal
over long distances using telephone wire or any other twisted pair wire thus extending the range of
operation of a DA. The TP-1 maintains the bandwidth of an industrial color video signal up to
several hundred meters and of broadcast quality (up to 12 MHz) signals up to 100 meters. At shorter
distances, as in a studio, bandwidth of 30 MHz is easily achieved. By using the KRAMER TP-1
together with the TP-2 (Video Line Receiver) coax wiring (in a studio for example) can be
completely eliminated. The TP-1 can also be used for simplification of security and CCTV
installations, and for teleconferencing in offices and hospitals using existing intercom or telephone
wiring.
VA-11AV - (Video/Audio Combiner) Used to distribute audio/video signals. The machine can be
inserted in front of a DA, allowing the DA to distribute a video signal and two audio signals
simultaneously. It sends a color video signal and a stereo audio signal using only one standard coax
cable in real time. The machine maintains the bandwidth of an industrial color video signal and the
output signal may be viewed and recorded as a normal video signal. By using the VA-11AV together
with the VA-12AV (Video/Audio Separator) the audio stereo signal may be recovered so audio
signals may be sent in a hidden mode, to be recovered only by the VA-12AV. The VA-11AV can be
used for simplification of security and CCTV installations, using existing video coax wiring for
video and audio transmissions.
611T/611R - (611T full bandwidth Fiber Optic Transmitter and 611R matching Fiber Optic
Receiver) Part of the KRAMER TOOLS series, and designed for studio and other demanding
applications. These machines, in combination, may be used to send one of the distributed channels to
distances of 5-25Km. The 611T and 611R use state-of-the-art fiber optic circuitry and allow the user
(via rear panel trimmers) to adjust input and output video levels and high frequency peaking to
achieve best performance. Both machines, like all KRAMER TOOLS, are fed from a 12VDC source,
making them perfectly suitable for fieldwork as well.
VIDEO TESTER - A new, unique, patented, indispensable tool for the video professional, the
Video Tester is used to test a video path leading to/from an amplifier. By pressing only one touch
switch it can trace missing signals, distinguish between good and jittery (VCR sourced) signals, and
identify the presence of good signals. Whenever a video signal is missing, because of bad
connections, cable breaks or faulty sources, the Video Tester is all you need.
