Danbridge decade inductor as Pleiades hi pass filter


Directly connected to mic in parallel.


Nice variable low cut. But unsusable as hum and noise is excessive.


On the other hand winding in a magnetic toroid (ring) core produces no noise at all.


Nevertheless for example 500mH were found suitable for the Audio Technica AT-802. So perhaps it's time to wind a 500mH indictor on a ring core.
