I experimented this weekend and I discovered that I just wasn't outputting enough level to the speaker to get the volume I needed. I took a brand new patch and inserted a Deluxe Normal (I think that's what it's called - I'm not at home right now) into the patch and, without touching anything, played it with my Les Paul with the output knob on the Helix set all the way clockwise. I also double-checked the global settings on the Helix and made sure the XLR output was set to "Line". I set the volume on the K12 to 0 dB and watched the clip light on the back. No clipping - not even close. I then upped the output at the far right of the patch to +20db and played - definitely clipping! I backed off to +10 dB and found that even with distortion boxes and whatnot, I was not clipping. At +10db, the speaker was way too loud, which is what I would expect of a 1000 W PA speaker of this quality. Problem solved. This brings me to the point where I wish there was a global output level. Stock output level is too quiet for a rock band, if you're only using one FRFR speaker. I'd rather have the output knob at 12 o'clock for normal use, just knowing I could get stupid loud if necessary. I am very cognizant of my hearing and I'm constantly begging the drummer to stop using his crazy metal shell kit for the sake of all of the band members' ears and the audience. If he can't tone it down, it may be time for a new drummer.
