Hey there, i'm looking for opinions on the best upgrade from an old Behringer Ultragraph 31 band two channel that has deveolped a nasty buzz/hiss whenever the sliders are moved in any direction from flat. I really wish I could get it into one rack space instead of the three that the Behringer takes up. I'm looking at the DBX dual 15 band, is this a good choice? Application is for local bar band performances FOH and monitor EQ. What are you using as your sonic standard go to graphic EQ?
