Using the EMI RS106A as presence equalizer

It may be possible by adding a series resistor and then connect in parallel with the output of a microphone. This can then be used to compensate Fletcher Munson curves to give presence to voice.


Similarly one can use a Pleiades filter or an inductor in parallel with a capacitor and then two series arm resistors and the total in parallel with mic signal.


The Pultec equalizer seems to have used moly permalloy toroidal cores as written on the web.
