HDTV Supplys WolfPack 8x8 Matrix HDMI Switch w/LAN & RS232 Control provides the most flexible and cost effective solution in the market to route high definition video sources plus multi-channel (up to 7.1-channel) digital audio from any of the eight HDMI source devices to the remote displays at the same time. Because it is a matrix switcher, it allows any input to be routed to any output; or the same input to be routed to all outputs, or any combination. The matrix also has optional 4K and can even use the TCP/IP controls to manage the unit from a web browser.
