This thing is a piece of garbage. I have my tv in and my xbox in to my stereo out. even when the xbox is completely turned off I get static. there is no static in fiber optic! it depends on if I put it in upside down or not how bad it is. that makes no sense either but it works better upside down. I now use it to simply connect 2 shorter cables and extend them. don't buy this. you can't split a light! get a switch.
