A:AnswerIt's 17 and 1/8" wide, 16 and 1/4" deep and about 4.5" high. I was still able to get it into a small corner because of the way the feet are laid out on the bottom. At first I thought it wasn't going to fit because it is a lot bigger than my amp but it worked out fine.
A:AnswerDirectly, no because the only output is stereo audio plug. It would have to be connected to a sound bar via a subwoofer or direct to stereo connection on an external amplifier or television with those connections.
A:AnswerYes as long as there is a stereo input jack connected to another external source such as a television, subwoofer or amplifier connected to the sound bar.
A:AnswerI don't think so, at least if it does, it's not spelled out on the control panel. I haven't really read the manual yet though so it's possible it can.
