Posted on Monday, April 30, 2012


Mount Vernon, NY. Key Digital Systems, Inc. – March 16, 2012 - The Experts in Digital Video Technology and Solutions are proud to announce our newest digital video distribution solution: the FatCat Series™ model KD-CATHD500 HDMI balun kit. This HDMI balun kit is designed especially for commercial and residential applications where long CAT6/STP cable runs are impeding digital video signal transmission. As leaders in digital and analog video technology, Key Digital® produces a variety of HDMI baluns to provide solutions to installers for both residential and commercial A/V systems. KD-CATHD500 now offers runs of up to 400ft. on 1080p/60 using our FatCat Series™ model KD-CAT6STP1X CAT6 STP cabling solution. The KD-CATHD500 is also equipped with ethernet ports to pass streaming online media to displays, and the transmit ends of both models offer a built in HDMI pass through – the first of its kind. Key Digital’s first ever HDBaseT balun kit also offers bi-directional and simultaneous control features; further proving the versatility of the FatCat Series™ family of HDMI baluns. The KD-CATHD500 are one of the first balun kits to have an EDID control built in which ensures a proper handshake between HDMI devices every time. Key Digital® President, Mike Tsinberg, stated that, "The KD-CATHD500 opens a new window of opportunity for Key Digital as it is the first 10gBaseT Balun kit with available IR and RS-232 (bi-directional and single direction)." Today’s installers need reliable, easy, and fast integration of video and audio in both residential and commercial applications. The KD-CATHD500 simplifies HDMI installations offering all video, audio and control capabilities needed for the most technical applications.
