I have been using akg ck91 ->3wire battery box-> r9hr. I recently picked up a pair of at853 that terminate to (2) mini xlr's.
Would I be able to power the at853's with the akg 3 wire battery box?
Are all 3wire battery boxes built/wired the same?
Short answer, no. Different mics have different leads assigned.
If your bbox is custom built there's no way to tell unless you open, and/or measure the current on the terminals.
