1.1 A Word on Video/Audio Switchers
A video/audio switcher switches between several sources (inputs) and one or more acceptors (outputs). A
switcher that allows several inputs to be connected to several outputs simultaneously is called a matrix switcher.
Switchers may be of the electronic or mechanical type. Most matrices are of the active electronic type, with
many crosspoints. Vertical Interval Switching, frequently used in video, ensures that the transition from one
video source to another (such as switching between two genlocked cameras) is smooth and without interference.
The switching and changeover is done during the blanked vertical interval period, when the transition is hidden
from the eyes. Vertical Interval Switching is needed when recording or transmitting a video program involving
several video sources, as in live broadcast, to ensure clean, undisturbed picture transitions. The switched sources
should be genlocked. Matrices and switchers are sometimes RS-232 or RS-485/422 controlled. Each of these
options is a way of remotely controlling a video/audio device (switcher, etc.) using a PC with a serial port, or
another device that uses a similar communication protocol. The simplest connection between the RS-232
controller and the controlled device uses two wires (TRANSMIT, RECEIVE) and a common ground wire.
Finally, the wide video bandwidth permits the matrix switchers to be used in the most demanding applications.
1.2 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
breaks 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.

4.1 Optional Accessories
The following accessories, available from Kramer, can enhance implementation of your machine. For
information regarding cables and additional accessories, contact your Kramer dealer.
#
VM-1055 – a 1:5 distribution amplifier for component video (RGBHV) signals can be inserted serially
between one output of the VP Matrix and several (up to 5) RGBHV acceptors for signal distribution. The
VM-1055 has five separate channels, each of which is a high bandwidth 1:5 DA. In its typical application, it
is designed to accept a component video source such as RGBHV, RGBS or Y, R-Y, B-Y, etc., and provide
five buffered outputs to drive monitors, projectors, or other receiving devices. In addition to a typical RGBHV
application, the five channels can operate independently, allowing the unit to be used as five separate 1:5
DA’s for composite video or other formats. Bandwidth of over 300MHz ensures that the VM-1055 remains
transparent eve n in critical broad cast or high-resolutio n applications. It is housed in a rugged, professional,
rack mountable enclosure requiring only one vertical space in a standard 19” rack.
#
VP-102 (and the new VP-103) - a high performance VGA to B NC converter which is designed to allow a
single VGA/XGA source to drive a local monitor and a compatible large display device simultaneously. It can
be inserted between a VGA/XGA source (such as a PC) and the input of the matrix. Many projectors and
large monitors provide BNC connectors rather than multi-pin D connectors. The VP-102 solves this physical
incompatibility, and provides the local monitor loop-through, necessary buffering, isolation, and sync
processing for electronic compatibility. Note that the VP-102 does not
perform any scan rate conversion. The
VP-102 will accept all typical VGA modes such as VGA, SVGA, and XGA, and output RGsB, RGBS, or
RGBHV. Video bandwidth of 315MHz ensures transparent operation at multiple resolutions including XGA.
For applications not requiring a local monitor, a rear-panel termination switch is provided eliminating the
need for external termination plugs. The VP102 is rugged, depend able, and runs on stand ard 230/115VAC
via an ordinary detachable AC cord.
#
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 a Matrix Switcher. 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.
#
SP-11 - (Video/Audio Processor) can be serially inserted between the Matrix Switcher and the acceptor for
video/audio processing. The SP-11 has 2 Composite video inputs and outputs, 2 Y/C (Super-Video) inputs
and outputs as well as 4 stereo-audio inputs and outputs. The SP-11 has DC coupled video inputs and outputs,
and 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. Input switch control is "Audio-follow-Video".
