The Gefen DVI Audio Extender extends your DVI and digital/analog audio up to 200 feet away from your HDTV DVI or HDMI source using cost effective CAT-5 cables.
The DVI Audio Extender sender unit sits next to your video source such as computer, DVD player or any set-top box. The cables supplied with the DVI Audio Extender connect your video source/audio source to the sender. Your display/audio receiver plugs into the back of the DVI Audio Extender receiver. Two CAT-5 cables* connect the sender and the receiver units to each other
NOTE:A shielded CAT-5e or CAT-6 cable for DDC is recommended for optimal video quality. The video CAT-5 cable does not need to be shielded.
