This product has been retired.

The Extron RGB 198 is a universal, analog computer-video and audio interface with two unswitched AC outlets, openings for up to four MAAP - Mini Architectural Adapter Plates, and DDSP™. It allows computer-video resolutions up to QXGA to be converted for output to projectors and flat panel displays. It also accepts unbalanced computer stereo audio and converts it to balanced, line level stereo or mono audio. The Extron Digital Display Sync Processing or DDSP technology allows the sync signal to pass through without altering sync pulse or width. The RGB 198 is ideal for use in applications that require signal amplification and sync processing to ensure compatibility between many different types of displays and computer-video signal sources found in classrooms, auditoriums, and conference rooms.

In addition, the RGB198 interface features a buffered local monitor output and ID bit termination. Level and peaking as well as horizontal shift controls can be accessed via the front panel.

The 1U high, three quarter rack width enclosure is specifically designed for under-table and rack-mountable installations.
