The DA1926AV and VA6803SX interfaces are designed to resolve incompatibility issues that occur when displaying a computer image on a large screen data projector or on a large screen monitor. Both are high-resolution computer video interfaces with stereo audio and are designed to allow the connections of VGA, SVGA, XGA, UXGA, MAC, SUN, SGI, and other analog computer video sources to scan-rate compatible monitors, projectors, and LCD displays.

These interfaces amplify video signals and convert various sync formats. They do not change the scan-rate or the resolution of the video signal. The computer and projector must be scan-rate compatible with each other. The DA1926AV and VA6803SX can equalize the attenuation effects of long cable runs, up to 300ft (91m), or more, depending upon the type of cable.

Each unit provides fully buffered main and local video outputs. The DA1926AV has two main outputs that are provided on 15pin HD connectors. The local video outputs are provided on a 15pin HD connector. The DA1926AV does not separate sync from green.

The DA1926AV and VA6803SX each accept stereo audio inputs and offer a balanced stereo output as well as a local stereo output. The input and local output use 3.5mm jacks, while the main outputs are provided on 5pin terminal blocks for stereo audio transmission to the main sound system. The main output can be wired for balanced or unbalance audio.
