Glad you’re liking the boards! To be honest I can’t say whether it’s proximity or not. You could try and get a bit of space between them and wrap some aluminium/copper foil in kapton tape to shield them. Might do something , might not.[quote=“Durdee, post:113, topic:53345, full:true”]
Just got a tx-6 and with a usb stick, the mic pre turns it into an extremely serviceable field recorder! With the onboard gain these mics get shockingly sensitive with very little noise!
I tried to build a box with two stacked inside, separated by kapton tape and it worked, but with the gain up a bit I got some really strange complex noise. I’m wondering if it was the proximity of the boards or that they were sharing a battery? Anyway, hardly a bother, gonna order a couple more of those excellent enclosures and separate the boards and see if that helps.

Did this power option work for you by any chance?
no, i ended up not using these for the project i was working on at the time and didn’t get around to testing them. i’ll try soon and report back for reals this time.
edit: if anyone can remember where i put the cable i got for testing, i’d be grateful.

Sounds good! No rush and thanks for the reply

@mmryspace, by some minor miracle i bumped into the 9v usb adapter this morning and hooked it up to the mic pre and it worked! i just did a quick test with a powerbrick, so not sure about any differences in noise levels using a usb adapter vs a battery.
anyone going this route to power their mic pre will obviously need to be mindful of connecting the correct positive and negative wires going into the board. <3
