The high performance "Educator Series" XR-20X projector, with 2300 ANSI Lumens and XGA Native Resolution, is designed to handle most business, education or cinema projection requirements with ease. DDR DLP display technology from Texas Instruments, a 3x speed, 4-segment color wheel, and TrueVision (DDP2000) image processing combine to deliver superior color quality and brightness. The 20X prevails in extended-use operation thanks to multiple ultra-quiet cooling fans along with extended lamp life. Ideal for portable use and higher-end integration, the XR-20X features a full complement of inputs and outputs (including RGB-loop through, stereo variable audio line-output and RS-232C).
