Product Description

The ST-766 (1×4) & ST-776 (1×8) HDMI CatX Splitter Extender over CAT5 provides the most flexible solution by which the high resolution PC video and high quality stereo audio can be transmitted to different locations over super long distances. These devices are cascadable, allowing you to extend HDMI compliant displays almost anywhere. The input HDMI source can be duplicated and distributed to up to 4/8 HDMI enable displays through cost effective Cat-5/5e/6 cables with HDMI over CAT5 receivers. With the built in equalization, the input HDMI cable can be extended up to 20 meters (66 feet) long under Full HD, and make the overall transmission distance superior than regular HDMI splitters or matrix switches in the market.
