The HDBaseT 4 by 4 HDMI Matrix over CAT5e/6/7 supports the transmission of video (resolutions up to 1080p Full HD and 1920x1200 at 60 Hz) and multi-channel digital audio from four high definition sources to four outputs over a single CAT5e/6/7 cable (up to 100m) for each output. It supports high resolution digital audio formats such as LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio as well as 3D content that can be displayed when connecting a 3DTV and 3D source. The matrix can be controlled via IR, RS-232, Telnet or Web GUI. Power over Cable (PoC) support means that compatible receivers do not need their own separate power supplies, allowing for greater flexibility in installations.
