VERVIEW

The Dual System Video Converter
will enable you to convert your
computer monitor signal into a
form suitable for VCR recording,
conventional TV or video monitor
display, or integration into a
multimedia production system.

The Dual System Video Converter
is a plug-and-play unit. After you
have connected it to your equip-
ment, you are ready to go.

By adding the Sync Genlock
(available separately), you can 
have full studio timing capability,
providing control over both
subcarrier and horizontal timing.
