The way I understand, the preamp is always in the circuit. Is that not the case?
There's always something between the mics and the iriver...whether it be the preamp, my homemade bbox or the AT8505s/PS2. They all get interference. The PS2 less than the other two.
Can the at853's in the 3-wire config be powered by the iriver plugin power? If so, could someone please tell me how to wire a 1/8 plug to 2 mini-xlr(m). That way I can test with just the mics and iriver.
Unfortunately I don't have a different recorder. Oh, I suppose my partner's got an iriver H10 I could use. Only records to mp3...but it may be better than nothing for testing purposes.
I thought it was safe to say that it wasn't the iriver because I don't get the interference from the GSA mics (w/ ~5 foot cables)?
So these are not shielded cables? I was suggesting to lift one end of the shield or the other, but if the only ground is power ground, then you obviously can't do that.
Sorry...I don't know (showing my ignorance here but i thought shield/ground were interchangeable)...there's two yellow wires, two red wires and the shield/ground 'thing' wrapped around 'em.
Did you ever test with the cables out of the pot but the mics and the bbox/pre/iriver in?
I did, but unfortunately the slightly open pot-lid makes these tests inconclusive. I had interference with everything, apart from when the whole kit was in the pot (ie the only time the lid was fully closed).
Maybe I should just wear the pot to gigs? ;-)
