Hey, I need some help with receivers. I recently ordered a set of ATH-A900 headphones, and I need to connect them up to my Xbox 360 and Toshiba 32WLT66 TV. I also need to connect them to my PC, but that will be easy because I will just plug them straight in. The problem I have is connecting the headphones to the Xbox and TV. The TV has phono audio out, the red and white cables. The Xbox has the same, but it also has optical out. To connect these to the headphones I have been told I need a receiver. I'm not looking for a top of the range system, to be honest I don't even know what a receiver is fully capable of doing in a home audio setup. All I want to do is get my new headphones connected up. Can anyone help? Thanks in advance.
