Both your 3203's [8dB(A)] and your ME-66's [10dB(A)] have self-noise rating=
s which should be "quiet" enough to reveal the possible difference in pre n=
oise beteen the two recorders. (self-noise ratings: http://www.uwm.edu/~typ=

Yes.

s, and recording level set to maximum? Or do you mean just mic >gains set t=

Both. Trims set to maximum signal and the Master knob also set to full. Rob=
 D.

ise, you can get a practical answer by recording empty presence or room ton=

 takes to improve chances of uniformity in the background sound. Make a 3-5=
 second excerpt from the quietest section of each recording. Post the 2 cli=
ps and one of use will match playback level and provide some feedback. Rob =
D.
