Thanks for the input!
No I use the stock config + calibration. How do I change it?
You have to unscrew the bottom ring. It comes out easily if it’s not glued by creating a spanner wrench out of a paper clip.Early revisions had glue which requires using something like Goof Off.
“Some of the early microphone had that ring glued by mistake so it's not very easy. All latest batch can easily be opened with a simple tweezer inside the 2 holes of the ring at the bottom of the microphone (USB connector side)”
You then adjust one number in the calibration file. My UMIK-1 is an 18 dB version with micro USB. The first gen had 12 dB. The latest version is usb-C. I had to unglue mine.
