Along these lines, I was talking to tech support ant explaining to the person on the phone that "low" records my band way too low and high records my band with clipping, at least this was true on the Zoom H2. I would also get clipping on medium. Now obviously the Q3HD, which I just received, does NOT even have a medium setting, so the tech advised me that on both the Zoom H2 AND the Q3HD, I can set the input gain on "high" and then monitor clipping on the unit and fine-tune the input gain to prevent clipping by adjusting the sensitivity. He said on the H2, I could use "left and right" (which look like FF and rewind - left and right on the "cross") and that up and down would do this on the Q3HD. However, in messing around with this, while in front of my TV as a test, I could NOT change the meters. There appeared to be a slider that worked, BUT it went up and down (and left and right if I went left and right on the round pad) but the record meters did not change. This is somewhat puzzling. I want to record a very important concert tomorrow, and I need to make sure I get this right.

Edit: Okay I tried it on my H2 and it worked. I set the unit to "high" but using left and right I was able to lower and raise the record level from 100 to 0 and I could see a pronounced effect on the moving record meters. Not sure how to do this (fine tune the input volume) on the Q3HD within the two settings (high and low)
