Re: Olympus LS-7 vs. LS-11

Per B=E6kgaard recently measured the noise floors of the Roland R-05 at var=
ious gain settings:

Certainly the diagram at http://www.b4net.dk/wp-content/uploads/2010/11/EIN=
vsGain3.png nicely shows that the lowest noise floor can only be obtained a=
t the maximum gain setting. I believe that this is a general rule that appl=
ies to (almost) all field recorders.

It can also be seen that there are indeed still acceptable noise levels at =
lower gain settings. In the field, one should therefore select the minimum =
gain setting at which the microphone noise just masks the preamp noise floo=
r. Unfortunately, this optimal setting would heavily depend on the specific=
 microphone model.
