Mount Vernon, NY– Key Digital Systems (Key Digital), a leading total systems solution provider of custom installation and home theater digital video products, is proud to continue its product expansion to embrace the HDMI digital interface with the introduction of its state-of-the-art digital HDMI 4x1a Switcher. The HDMI 4x1a Switcher by Key Digital is a high-quality, versatile HDMI switcher that supports HDCP Copy Protection and switches any of four (4) inputs of HDMI video and audio to one (1) output. The amazing HDMI 4x1a Switcher can also pristinely scale 480i, 480p, 576i, 576p, 720p, 1080i video inputs to the native resolution of any display, at 60 Hz and 50 Hz.

HDMI is everywhere, as more and more video and audio products support the all-digital, plug-and-play HDMI interface. So many sources, like DVD players and HD Set Top Boxes, provide HDMI outputs. Key Digital intelligently engineered the HDMI 4x1TM Switcher with the latest in state-of-the-art technologies and features, to easily and conveniently switch these sources to your display and provide the absolute best, crystal-clear, and pristine picture quality. That’s exactly what you’ve come to expect from Key Digital, the experts in digital video technology and solutions.

The HDMI 4x1TM Switcher is ideally suited to interface a wide array of source products with an HDMI (or DVI-D output, with optional adapter), like a DVD player, Satellite Box, HD DVR, Set Top Box, or even a PC, to any display with an HDMI or DVI input. Not only can any of four sources with HDCP be selected for display, but with Key Digital’s HDMI 4x1TM Switcher, the selected input video can be scaled to match the native display resolution, using world-renowned Key Digital Clear Matrix Proa technology.

The power of the HDMI 4x1TM Switcher does not end there. An easy-to-operate, full-function, high-quality Video Processor is built into the switcher. For each input, a broad range of functions can be controlled, from Brightness and Contrast, to Size, Position, and even Zoom Aspect Ratio adjustments. Test patterns built-into the HDMI 4x1TM Switcher help set-up any video system. All the video processing features one would expect from Key Digital are also provided and accessible via the convenient front-panel display and pushbuttons, the IR Remote Control, or RS-232 to easily control all features of the product.

The HDMI 4x1TM Switcher by Key Digital is available now, with an MSRP of $1,000.
