About the VSC 150
Extron’s VSC 150 is a high resolution computer-to-video
scan converter with all digital controls. The VSC 150
converts a computer video signal into two display outputs
– composite video and one of the following:
• S-video,
• component video, or
• RGB video (RGBHV or RGBS)
for simultaneous scan-converted output on two separate
devices. This allows the video from a computer to be
displayed on a television monitor or recorded on a DVD,
VCR, video editing bay or other recording device. All of
the outputs are NTSC/PAL.
This scan converter accepts one Macintosh or VGA
computer input of a resolution up to 1152 x 900 and
provides a local monitor loop-out.
The VSC 150 is 1U high and one half rack wide. It is rack
mountable, and has an internal, autoswitching power
supply. It can be controlled via front panel buttons, RS-232
remote control, and infrared (IR) control.
