m audio black box problems

im plugging into a pc / windows xp but i really havent gone that far yet.i thought this was also a stand alone unit so i plugged in my guitar and headphones and got nothing. i sent the main outs to powered speakers and got nothing.the drum signal is audible but very low when speakers are ckanked.i tweaked the gtr/drumbal parameter which also did nothing.this unit was actually the floor model at georges music,last one,but i was impatient and had to have it.
