Hi i'm having troubles getting my rig running. I have my Pod HD Pro X going 1/4 unbalanced output to an XLR input on the Crown Xls 1000. From there i'm going speakon output from the crown to 1/4 input on the back on the cab. I hear a slight buzz from the cabinet but i cant get any guitar sound out of it. The Poweramp is also set to bridge bypass if that helps. Any help/advice would be appreciated.
