Impedance of the Fostex M20RP s/n80843 microphone


The output impedance of each mic element is about 700Ω-800Ω.


This explains why the matrix transformers have a high inductance.


Measurement was done with an Escort digital impedance meter and not a DC resistance meter in order to protect the printed coils from damage.


Elements on how it sounds like at a previous post.
