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  VS-4E  switches  video,  SDI  and  any  other  high 

frequency signals. The VS-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 VS-81AV provides high isolation between inputs and outputs and all unselected 

video inputs are internally terminated with 75-Ohm resistors. The VS-81AV is housed in a professional 

19" rack mountable enclosure.  

VS-801xl

-  (8:1  Composite  or  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 and one output. Switching is done during 

vertical interval, either of source #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.  

TP-1

  (video  Line  Transmitter)  If  a  DA  output  is  sent  over  a  distance  of  100  meters  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  30MHz  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 unused intercom or telephone wiring. 

VA-11 -

 (video/audio Combiner) Used to distribute video/audio 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  in  real  time  using  only  one  standard  coax  cable.  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  Fiber  Optic  Transmitter  and  611R

 

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  full 

bandwidth 611T

 

and matching 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.  

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.
