Hi. I have a Denon PMA500AE amp and an Xbox 360 hooked up to a Hyundai W240D monitor. I want to take the audio from the component cable and plug it into my amp. The thing is the computer is already plugged into the AUX port on the amp. Is it safe to use one of the other inputs (say tape deck or CD player) for my Xbox 360 or will that damage my amp at all?
