3 Overview
The VS-5x5 is a true 5x5 matrix switcher for composite video signals and
balanced stereo audio signals. The high quality VS-5x5 lets you
simultaneously route any or all of the 5 inputs to any or all of the 5 outputs.
The VS-5x5 5x5 Video Audio Matrix Switcher includes:
 Video bandwidth of 70MHz that ensures transparent performance
 Easy-to-connect detachable terminal block connectors for the audio
signals
 Glitch-free transitions, which are produced when sources share a common
reference sync, as switching occurs during the vertical interval
1
. Any input or
special external sync input may be selected as the vertical interval source
 DC coupled inputs and outputs
 Audio-follow-video and breakaway options
 Storing and recalling setups
 “Take” button for precise switch control
 “Lock” button to prevent tampering with the front panel
 Gain control for all inputs and all outputs
 The ability to control via the front panel buttons, via the Infra-red remote
control transmitter, and remotely by RS-485 or RS-232 serial commands
transmitted by a touch screen system, PC, or other serial controller
To achieve the best performance:
 Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
 Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-5

5 away
from moisture, excessive sunlight and dust
4 Your VS-5x5 5x5 Video Audio Matrix Switcher
Figure 1, Table 1 and Table 2 define the VS-5x5 5x5 Video Audio Matrix
Switcher:
1 When one video signal replaces another video signal, the switching process causes a random interruption in the first video
signal (in the middle of a frame) and a random entrance into the second video signal (also in the middle of a frame). The
result is a visible jump in the edited tape. This deteriorates when the tape is copied, and the disturbance on playback is more
serious. Avoid this by switching at a very specific point during the vertical interval, allowing smooth replacement of a whole
frame by a second whole frame as long as the video sources are Genlocked to each other

2. Press one of the 10 Input / Output buttons (this will be the setup # in
which the current status is stored). If in the CONFIRM mode, press the
blinking TAKE button to confirm the action.
The memory stores the data at that reference.
7.5.2 Recalling an Input/Output Configuration
To recall an input/output configuration, do the following:
1. Press the RCL button.
The RCL button blinks.
2. Press the appropriate Input / Output button (the button # corresponding
to the setup #). If in the CONFIRM mode, that setup configuration will
blink in the 7-segment Display, together with the RCL button and the
TAKE button, and will only be implemented after pressing the TAKE
button.
The memory recalls the stored data from that reference.
Tip: If you cannot remember which of the 10 input/output configurations is the one
that you want, set the VS-5x5 to the CONFIRM mode and manually scan all the
input/output configurations until you locate it.
