Still in lockdown repairing this very rare American D22 dynamic microphone. This mic has dual impedance. Behind the tag is a secret connector. Here you can switch from Low to High Impedance. The mic had some connection problems. I replaced all the wiring and set it up for Low Impedance because the owner uses it to connect directly into a PA for recordings.
