Title: Neumann AC30 cable for AK caps pin outs
Post by: tubems on April 30, 2014, 03:20:23 PM
Good morning

so a Neumann ac-30 cable came into my possession recently and i wanted to figure out how i can use this without the mtx191 matrix box.  and here is how i can... 

i called up neumann and sent an email to peter drehfal in germany and they both confirm these are the pin outs for this cable, below is directly from Neumann.

what this can give us is a way to run km100 caps off a $400 cable that hopefully we can run off of a pfa or tiny box.  The cable is terminated in a 7-pin XLR.

Hi Daniel,
Here is the mtx191a mic wiring. It's all I could find.

1- ground
2- +10v
3- -mid (L)
4- -50v
5- +50v
6- side (R)
7- not used.
