3  Overview 

The 

VS-808DS

 

8x8 Video Audio Matrix Switcher / Scaler

 is a high 

performance matrix switcher for composite video and unbalanced stereo 

audio signals. It lets you simultaneously route any or all of the eight inputs to 

any or all of the eight outputs, plus one scaled output

1

 (that is, output 8 also 

goes to the Scaler). Switching during the vertical interval ensures glitch-free 

switching with genlocked sources. 
The 

VS-808DS

 features: 

 

A video bandwidth of 200MHz that ensures transparent performance even 

in the most critical applications 

 

Switching synchronization that lets you synchronize either to the external 

reference or to the incoming video 

 

Both audio-follow-video and breakaway options 

 

The storing of eight setups

2

 (presets) to be recalled and executed when 

needed 

 

A TAKE button for executing multiple switches all at once 

 

The ability to control via the front panel buttons, via the infra-red remote 

control transmitter, via an external remote IR receiver (optional

3

) and 

remotely by RS-485 or RS-232 serial commands transmitted by a touch 

screen system, PC, or other serial controller 

 

Scaled graphics output resolutions: VGA (640x480), SVGA (800x600), 

XGA (1024x768), or WXGA (1366x768) 

 

Acceptance of PAL-B/D/G/H/I, NTSC 3.58, and NTSC 4.43 video formats 

The 

VS-808DS

 is housed in a 19" 2U rack-mountable enclosure and is fed 

from a 100-240 VAC universal switching power supply.

 

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 and position 

your 

VS-808DS

 away from moisture, excessive sunlight and dust
