Is this meaningful? I guess it may be higher for the mic preamps. With further testing, I think I can detect a similar change in gain effect from what Robin reported - I seem to be getting between -13.0 and -13.6 db at the lowest end of the spectrum for the snippet that is being played back. Seems a bit random where it comes though. I think they are analogue pots, so maybe this might account for this variance?? - anyway, I think it is too subtle to notice in normal use.
