Re: [Harp-L] Re: Low Z mics - Transformers

When Shure and some other companies started making dual impedence mics you
didn't need to do anything but buy the right cord. If you wanted to use it
low z you bought a cord that had the pins active for low z use. If you
wanted to use it hi z you bought a cord that made the hi z wiring active.

Rather then screwing with the wiring of vintage mics its best to find the
pins (3-4 pin models) that corrospond to the impedence you want to use then
wire your cable to match.

Back when I use to modify 545 mics for customers I would test the female
inputs for hi z use then wire the cable or 1/4 inch connector accordingly.
