I think your screenshot was over 1 megabyte so it didn’t show up, but I’d just suggest starting having your Focusrite inputs set at 0 gain, then slowly work up your QU-16 levels to where they need to be. If you need to get add some gain on the Focusrite, you’ll have plenty of head room. I’m assuming you’ve got some sort of metering to look at on your Focusrite correct? Get it up there but make sure it is not getting toward the reds.
