........I'd just add to Jfrech's comments that XLR is the type of connector that balanced outputs/inputs uses. RCA connectors (the most common kind) are the kind "single ended" outputs/inputs use.
The XLR inputs you see on your amp would be inputs, not outputs. The amps outputs connect the amp to the speaker and are often "five way" so that you can use many different kinds of speaker cable terminations, ie spades, bananas, bare wire etc. There is no agreement as to which is best sonically, but if you need long inter-connects, ie say more than 20 ft. or so, XLR is considered preferrable. I use (and prefer) RCA. Good Luck. Craig
