I don't know what i'm doing wrong, but when I plug my Line 6 Helix directly to a Behringer x32 mixer, it sounds terrible. I was expecting that when I connect it to the x32, it would give me the same result as when I put my headphones directly trough the Helix (what sounds fantastic). I just use a XLR cable from the main out (mono) of the helix, directly to the XLR in of the x32. I've no knowledge of the x32 whatsoever, so I don't know if the way it's plugged in is wrong, or it has wrong settings on the x32.
Help is much appreciated! :)
