Perhaps you have a brand and type of the amp ?

I've bought a cheap amp that said "AC3 input" in the manual. On the back are 4 sets of inputs. 3 of them are standard dual phonos, marked tape, cd, and tuner (left and right of each). The other is marked AC3, and also has two phono sockets (marked left and right). I was under the impression that AC3 was the bitstream format of dolby surround sound and required only ONE phono connector (or an optical toslink connector). Why do I have two phonos? I don't have the ability to give it a dolby bitstream yet to test it (waiting on a part), but I did try connecting a standard stereo analog input to the AC3 phono connectors, and it worked. Should it have? Could it be an analog/digital input?
