Flicker filtering control — The flicker filter level is user-
selectable from the front panel for control of flicker
reduction.

computer or another control device through an
RS-232 connection and Extron’s Simple Instruction

one side of an optional 1U rack shelf (Extron part

About the VSC 75

Extron’s VSC 75 is a high resolution computer-to-video
scan converter with all-digital controls. The VSC 75
converts a computer video signal into two display outputs
— composite video and S-video — 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 1280 x 1024, and
provides a local monitor loop-out.
The VSC 75 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 controls and
RS-232 remote control.

horizontally and vertically or pan across the picture
