If R,L values are found experimentally for particular mic, singer, song application ..

then a hardwired Pleiades R,L filter can be made inside Neutrik XLR modules.


For 250Ω mic impedance a value of 40mH has so far been found very useful.


A Neutrik module Pleides filter may be created with basic rotary switch variable resistance or inductance.


A disadvantage is that it may be a long XLR female to make adaptor.
