So I finally got rid of the power strip full of wallworts and my daisy chain 1spot and got a DC 10. It came yesturday and I hooked it all up, made sure everything was connected correctly and all was working. While at rehearsal last night got into a preset on my Empress SD which is plugged into output 8-(12v, 250ma positive tip using the red positive cable), and got horrible noise when altering the preset. it happened anytime I altered any preset. The pedal worked fine otherwise and everything else was working great. Do I need to leave outlet 7 open due to the Empress being positive tip? or is it the ma sharing getting in the way?? For my show tonite I will leave 7 empty and use a battery for one of my 9v pedals.
