Hi Oryoki,

Yes, there is a difference. The -124 dBu noise floor that I measured yester=
day only applies to the XLR ANALOG IN. The 3.5 mm PLUG-IN MIC is considerab=
ly noisier at -117 dBu (just added that number to the list).

The lower Input Clipping Level is caused by the very high maximum gain sett=
ing available on the R-26. Actually, all these clipping level measurements =
might be a bit confusing because they are just inversely proportional to th=
e maximum available gain setting of each recorder.

So, in order to prevent clipping, one can simply turn down the gain, which =
will however usually also (slightly) increase the equivalent input noise. I=
 also measured the noise floor of the R-26 XLR inputs at a lower gain (at a=
 clipping level of -58 dBu) and still got a relatively good noise level of =
-123 dBu(A).

Regards,
Raimund
