Hi Bob i was looking at my mixer again for hooking the mixer up to the power amp .I see there are XLR OUT PUTS on the back of my Mackie .I did not hook it up from the back but rather i hooked the main out from the top Bal/ unbal main out .So one end is 1/4 inch and the other end going to my power amp is XLR. Should i hook my mains from the back of the mixer and to my amp with XLR Only ? I wounder if that would make a difference in sound ? My power amp gives me an option either i can connect with 1/4 or XLR Inputs same does for the mixer. It apears the manule is saying the out mains are in the back of the mixer but do not talk about the main outs on top as far as a i can see .Which way would you hook it up ? Mackie pro FX8

Regards,
Greg
