The RCA inputs on the AP-009: center, sub, front (left and right), rear (left and right) and auxilliary. The speaker outputs: front left, front right, center, rear left, rear right, subwoofer left, subwoofer right. The volume controls: sub, rear, center, main volume. There are only two buttons: power (with corresponding blue led light) and AC-3 or stereo push button switch. Since it has no built-in Dolby Digital or DTS decoder, you have to use the built-in in your DVD player (if it has these features). I would reiterate that I have not yet tried it for home theatre applications. It sounds really good in audio stereo. The weight of this amp is 31 lbs.
