How to convert an AKG D112 to a great vocal microphone without modifying it

An easy way is to connect to it a Pleiades filter.


This is an inductor in parallel with the signal out (ie voice coil).


An inductance of 47mH to 82mH should be great.


It can all be fitted inside an XLR male to female adaptor, more information on previous euroelectron posts.


The magnetic core used can be a Magnetec 073 or an Epcos Siemens ferrite etc.


These filters will also electromagnetically damp pops.


The AKG D112 is an interesting candidate as its frequency response has similarity with Neumann U47. The sound on voice is extremely natural.


More information on how to make these on older and newer euroelectron posts.
