3 Overview
The high performance VS-626 (VS-828) is a true vertical interval Video /
Audio Matrix Switcher, letting you route any input to any or all of the outputs
simultaneously.
The VS-626 (VS-828) includes:
A bandwidth of 100MHz that ensures transparency even in the most
critical applications
6 (8) input and 6 (8) output button selectors
8 preset memory locations for quick access to common configurations 1
Audio-follow-video or audio breakaway option (to switch audio
independently from video)
A unique vertical and horizontal sync-pulse solution
Glitch-free transitions, which are produced when sources share a
common reference sync, as switching occurs during the vertical interval 2
An external Sync/Genlock input that may be programmed to switch
according to the timing of either this input or of source number 1
You can use the RC-IR2 IR transmitter to control the machine via the built-in
IR receiver on the front panel or, instead, via an optional external IR
receiver 3 . The external IR receiver can be located 15 meters away from the
machine. This distance can be extended to up to 60 meters when used with
three extension cables 4 .
Before using the external IR receiver, be sure to arrange for your Kramer
dealer to insert an internal IR connection cable 5 , which is required so that the
REMOTE IR 3.5mm connector can be used. Connect the external IR receiver
to the REMOTE IR 3.5mm connector.
1 On the VS-626, 8 preset memory locations are available via RS-232
2 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
