3. Overview

The VS-812 is a unique dual-format switcher and distribution amplifier for
composite and s-Video (Y/C) and balanced stereo audio signals. Each of the
eight inputs can be configured as either composite or s-Video (Y/C) and is
converted to produce composite and s-Video (Y/C) outputs simultaneously.

The VS-812 8x1 Composite / s-Video / Audio Switcher:
• Features high bandwidths of 370MHz (-3dB) for composite video, and

190MHz (-3dB) for s-Video (Y)

• Is a dual format 8x1 switcher with each input able to be selected as

composite or s-Video via the eight INPUT SETUP DIP-switches

• Includes built-in bidirectional format conversion: the two composite and

two s-Video (Y/C) outputs are live at all times regardless of input
configuration

• Features glitch-free transitions when the sources are genlocked
• Features vertical interval switching

1

• Is controlled via the eight front panel INPUT SELECTOR buttons or

remotely via RS-232 serial commands transmitted by a touch screen
system, PC, or other serial controller front panel RS-232 (K-Router™
Windows®-based software is included)

• Has a standard 1U 19” Rack Mount Size

To achieve the best performance:
• Use only good quality connection cables

• Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VS-812
away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables).
