Revox M 3500, another mic without an LRC filter needed to reduce high frequency peak

At your risk. Take all safety precautions. Protect your hearing.

According to above discussion the M201 uses an LRC filter to tame the high frequency peak.
(Later addition: it still has a peak, see datasheet:http://www.preservationsound.com/wp-content/uploads/2017/10/Beyerdynamic_1974.pdf)


This LRC filter can be seen in the datasheet:

A similar LRC filter used inside an SM7 to create flat electrical frequency response.

(L is series with R in series with L is connected in parallel to moving coil output, as seen in above Shure SM7 datasheet).


It may be interesting to create a Pleiades in line Neutrik module LRC filter for the M 3500 microphone.
