I'm not sure what you mean by "set to be pre", but I have my meters set to show input. The meters on the ux2 go up a little more when I put the gain to 3 o'clock and it's a bit louder, still a bit to quiet from what i've seen others experience, but it's not as crisp now. I'm guessing that's just a side affect of raising the gain.

Any tips on making it sound a bit cleaner? Perhaps a noise gate or equalizer?
Edit: added mic test with Studio vocal preset
