there is no such setting on the JB3 mic in - I will remain unconvinced...in a nice +T way...
ok fine. I'll maintain that they are lower than typical but of course one must always consider the recorder. Maybe the web page isn't clear.
same SPLs and mics, plugged into the JB3.
Recording #1 - mic in, 0 dB gain
Recording #2 - line in, 0 dB gain
Open the two up in a wave editor, rec #1 is flat sounding and 3 dB down from rec#2. Both are below full scale. If the mic pre were adding extra gain it would show up in the wave file.
In any case, I like your style, +t backatcha!
