Optional Accessories
The following accessories, which are available from Kramer, can enhance implementation of your switcher.
Rack Adapter
- Used to adapt smaller machines to a standard 1U rack. One or more machines may be installed
on each adapter (the
VS-101AV
is housed in a 19-inch, 1U rack enclosure so it doesn’t need a rack adapter).
BNC "Y" Connector
- Used for looping purposes and splits the incoming signal to enable connection of an
additional machine.
SP-11
- (Video/Audio Processor) can be serially connected between the video/audio source and the VS switcher
for video and audio control/correction. The machine may provide camera control and luminance/white balance
correction. The SP-11 is also capable of performing Composite to Y/C switching 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".
VM-1010
- (Video Distribution Amplifier) can be serially connected between the mechanical switcher and the
acceptors for video distribution. It is a full broadcast, state-of-the-art, and programmable video distribution
amplifier. The VM-1010 has two looping video inputs, each splitting to 5 outputs. The user may select 2x1:5 or
1:10 operation via front panel control switches. Several VM-1010 units may be chained through the looping
inputs. Output signals are (user selectable) DC or AC coupled for maximum flexibility.
VM-20ARII
- (Programmable Video/Audio Distribution Amplifier) can be serially connected between the
mechanical switcher and the video/audio acceptors for video/audio distribution. It is a full bandwidth, state-of-
the-art, 1:20 Programmable video/audio distribution. The VM-20ARII splits a single video and audio input
source into twenty identical outputs with no discernible signal degradation. The VM-20ARII has four looping
video and audio (stereo) inputs and a user programmable mode of operation. The VM-20ARII can function as a
1:20, 2x1:10, 4x1:5 or 1:10+2x1:5 DA, and audio operation mode may be separated from video mode. Output
signals are DC or AC coupled (user selectable) for highest signal fidelity. Due to the extended bandwidth of the
machine it can be also used for video/graphics component distribution. The machine has video gain and EQ.
controls for 4 sets of 5 outputs, as well as audio level controls. The audio section may be programmed to
function as unbalanced stereo or balanced mono.
VIDEO TESTER
- A unique, patented, indispensable tool for the video professional, the Video Tester is used
to test a video path leading to/from a 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. No need for oscilloscopes, waveform monitors or a Vectorscope to trace and rectify such
common problems. Indispensable for fieldwork, the Tester checks for sync and odd/even data in the signal and
is not triggered by noise, hum or even by a 15kHz non-video source. The Video Tester is compact (not much
bigger than a cigarette box), housed in sturdy plastic housing with pocket clip and is operated by a 9Volt battery
for three continuous hours of operation (the full shelf life of the battery).
