It was Raimund who pointed out that the best results with Olympus
LS10 could be had using the 'low' setting, even if on volume '10'.
And indeed I have found this to be so.  I have compared similar
sounds recorded on 'high' volume 3 and 'low' volume '10' and there is
less noise with the latter by a noticeable amount.  If you were
recording, say, on 'high' volume 5, then the same subject with 'low'
volume 10, then increased the levels of the latter in post, to match
the levels of the former (say by up to 6 dB), there would still be
less noise.

However if you are wanting to record a bird with a relatively soft
song, say using ME66 gun mic, you are probably better off to go with
'high' volume 5 to get a fully saturated signal.

Using Primo EM172 plug-in mics and also ME66 gun mic with my LS10, I
use 'low' volume 10 as my default setting.
