8:8 HDMI Matrix. This item is Untested and does not come with any power cables so I can not guarantee if it is working. I originally got it from a video rental company that went out of business so I am presuming it is working but like I mentioned I can not guarantee. As you can see from the photos it does look to be in good condition. There are no obvious marks or damage on it and all of the Ports seem to be in good condition as well.
