The PureLink HTX II-RX is designed for use with the HTX II-8800 Matrix Switcher to extend 4K/60 4:4:4 video, audio, ethernet, two-way IR, RS-232, and ARC (Audio Return Channel) signals up to 330 ft. (100m). The ARC function enables audio from a compatible display to be routed back from the HTX II-RX to the HTX II matrix. Using PoE technology, the HTX II-RX can draw power directly from the HTX II-8800, eliminating the need for additional power supplies.
