Klas, the EIN of the LS10 at its maximum gain setting is still -122 dBu(A) =
or -121 dBu(A) at SENSE LOW 24 bit.
The value of -113 dBu(A) only applies to an unappropriate setting (SENSE LO=
W at 16 bit resolution). This poor value is caused simply by the trucation =
of the original 24 bit samples provoded by the AD converter to 16 bits. But=
please do not generalize this particucar issue for other recorders. This a=
ll depends on the specific details of a recorder (gain steps and quality of=
the analog of the recoprder).
Unfortunately, such things can get quite complicated... Maybe I should just=
remove the number of -113 from my list?

Raimund
