If it's powered by USB, then it likely is a digital device. After what happened to Behringer, I would advise avoiding that unless you have the mics tested and certified for FCC compliance.
If I read the code correctly, certification is not required, just verification. That means you have to test to make sure that it A. doesn't send lots of noise back into the computer via the DC line (unlikely to be a problem) and B. doesn't radiate too much noise.
As far as I can tell, the code does not provide standard for testing A. given that the power supplied is highly filtered DC, which makes compliance almost a non-issue. So basically the one that would be a concern is B., and if I read the code correctly, this equipment isn't in a category that gets treated differently for unintentional radiators, so the intentional radiator requirements apply.

That said, IANAL, YMMV, SRAEMA-SSFD, CSA10222950.
I imagine the mic would have either a DC-DC converter, an A/D converter, or both. That would put in within the unintentional radiator rules of Part 15, as a Class B digital device (since it would use timing signals in excess of 9kHz).
As I understand it, that only requires testing by the manufacturer to ensure compliance with the technical standards of Part 15, and a label affixed to the unit. That's potentially easier and cheaper than a certified lab test, but it would still have to be done to comply with the regulation.
PS I wouldn't consider a USB +5V rail highly filtered for audio purposes . . .
I sent you an email in case no one else has yet.Specs are in for the "73" mic pre. Someone send me an E-mail,, you know the drill. I have to go to LA, and will reply with the specs to be posted when I get back

upon reading about the ams neve 1073 reissues, i've found that the transformer is an incredibly integral part of that 1073 sound. where are your transformers coming from? how close is the pcb layout to the original? isnt the 1073's gain control in 5db steps? by no means am i trying to be a skeptic, i'm sure these things are gonna sound awesome, and i'm stoked to buy a number of them, i'm just curious about how closely you've replicated them. thanks again, chance, you're really going above and beyond to help us all get our hands on some great gear. major kudos.
If you all notice I took all your questions and had them detail EVERYTHING in the specs. I'm doing some remote recording in June and would LOVE to have them for the gig.
Unfortunately the xfrmers are from China. It would be too costly to have them use some other trans. Those are upgrades that we can do at our liesure just like the mics. The specs for the 81 and 84 are coming soon. This is a new product for them and the specs have to be run and recorded in their lab.

this looks like a source for carnhill stuff: http://www.audiomaintenance.com/acatalog/Transformers_and_Inductors.html (but you said "old" -- these look new)sweet, thanks for the info chance. i'm gonna start keeping an eye out for old marinair/st ives/carnhill transformers. anyone know how common they are and what they might go for?
