VS-4E - (A Precision Mechanical 4x4 Video/Audio Switcher) Several video/audio sources may be
connected to its inputs for switching. The machine may be used in every application where easy and fast video
and audio source selection is needed and for high isolation between inputs. All unselected inputs are internally
terminated with 75-Ohm resistors. The VM-4E switches Video, SDI and any other high frequency signals.
The VM-4E is housed in a small enclosure, occupying very little desk space.
VS-81AV - (A Precision, Mechanical, 8x1 Video/Stereo-Audio Switcher) Several video/audio sources may
be connected to its inputs for switching. The machine offers fast and easy video/audio source and acceptor
selection. The VM-81AV provides high isolation between inputs and outputs and all unselected video inputs
are internally terminated with 75-Ohm resistors. The VM-81AV is housed in a professional 19-inch rack
mountable enclosure.
VS-801xl- (8:1 Composite/Single Component Video & Unbalanced Audio Switcher) Several video/audio
sources may be connected to its inputs for switching. The machine provides truly effortless switching between
eight, video and unbalanced audio inputs to one output. Switching is done during vertical interval, either of
source no. 1 or of the video available on the external sync socket. The switcher may be controlled by touch
buttons or by contact closure via a remote socket on the back of the machine. Video signal bandwidth is 225
MHz (typical), allowing the machine to be used in the most demanding applications.
VS-5x4 -(5x4 Video/Audio Stereo Matrix Switcher) Several video/audio sources may be connected to its
inputs for switching. The machine may be used as one 1:4 or two 2:2 Y/C-video/audio DAs or other
combinations as well. The VIS-5x4 switches during the vertical interval for smooth transitions between
genlocked sources. The machine is microprocessor and RS-232 controlled (software included), and is operated
by touching a keypad on the front panel. Front switches control the audio level of each output. Large
illuminated display LEDs show connection status at any given moment.
TP-1 (Video Line Transmitter) If one output is to be sent over a distance of 100 meter or more, it is
necessary to convert the signal to twisted pair type. The TP-1 converts and 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 signals (up to 12 MHz) up to 100 meters. At shorter distances, as in a studio, bandwidth of
30 MHz is easily achieved. By using the 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-11 - (Video/Audio Combiner) Used to distribute audio/video signals. The machine can be inserted
before a DA, to allow the DA to distribute a video signal and two audio signals simultaneously, 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-11 together with
the VA-12 (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-12. The VA-11 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.
