Oy. I hadn't looked closely at how the "needles" respond; it looks to me like they're peak reading rather than VU reading.

Anyway, I ran a -14dBFS 1k tone through it, and the needles on the standard Anna VU visual deflected to the right edge of the second segment from the left. So that would be about +4VU on the EBU scale, which should peg the meter. Or, perhaps I'm missing something -- I'm not giving this a lot of thought, unfortunately.

Given that, I think it's probably best to just have a fun little visual, as we have, and ignore what I said earlier.
