A:AnswerIf you are talking about a pc, yes only via the sound card built in on the pc and use a "Y-Cable" which has a headphone connection with red and white rca jacks on the other end then you connect the headphone end to the small green jack on the pc then connect the rca ends to the cd input on the reciever and select "CD" for input source on the front of reciever.

A:AnswerIt's kicking out 115 pure watts but it sounds like 150 watts with the right subwoofer added. The true output is added all together to get your 300 watts. It's basically a selling point. I must say though that this unit can entertain a nice size living room full of people with no issues. Sony subwoofers and bookshelf speakers work perfect with this unit as long as their output is at least a 100 watts.
