I am using 3.5mm jack from pc into aux in on alesis dm10 module I am then taking one of the line outs to a Mackie 15 active speaker for live play, am I losing any signal strength/quality by just using a single line out ie the other line out is not being used or is there a way to output mono only on superior drummer 2 if it is an issue, other option I suppose is buy another speaker, appreciate comments or advice
