Pro Power 48v, both fed the AT3032. Below are the links to the results (swf=

the IRigPre. I used a Sony M10 with IRigPre on Line IN and ArtPhantom2Pro =
on Mic IN, matched direcly during recording, no in post production.

Hi Marco,
I agree that there is no big difference between the two in your test.
I measured the EIN value of -113 dBu in conjunction with a Samsung Galaxy S=
II smart phone. So, it might be that there was really an additional noise c=
omponent originating from the poor input of the phone, which could mean tha=
t the performance of the iRig alone is actually better than that -113 dBu v=
alue.
Another thing to consider is the noise voltage of microphone. According to =
the specs it should be -110 dBu (19.9 mV/Pa, 16 dBA). That 3 dB difference =
(in conjunction with the smart phone) would cause only a relatively small o=
verall noise floor degradation.
Regards,
Raimund
