I'm now considering getting an Olympus LS-7. Becuase I can find almost no
references to anyone using these for nature recording, I'm trying to check how
similar it is to the LS-11.
I see these figures for input level in the specs sections of the manuals of the
LS-7 and LS-11:
LS-7: -70dBv
LS-11:
- mic sense high: -59dBv
- mic sense low: - 39dBv
The LS-7 does have high, low and medium mic sense settings like the LS-11, so I
assume the -70dBv refers to the high setting. It's very different to the
LS-11's -59dBv - is that good or bad?
Can anyone explain to me the significance of the figures on this page in
relation to the LS-11 and the LS-7
(http://www.avisoft.com/recordertests.htm<http://www.avisoft.com/recordertests.htm.>)?
I've reformatted them to look more readable. Looks good as I type this, but no
idea what it'll look like once it's been through the listserver. Is there
anything worth noting about the LS-7 in these figures?
