The inductance of the leads would have to be kept as low as possible so think really short.
But do you really think a series inductance of maybe 50nH matters?- Own Opinions Only -

I also like the insulting coating / covering ideasExperience is something you get, just after you really needed it.

Sure! At 1GHz that's over 300 ohms. Think WiFi 5.4GHz, radio mics 0.8GHz, cell phones 0.8-1.8Ghz. It's dirty out there.
Mic and instrument cables act as low pass filters at high frequencies.Last edited by Helmholtz; 07-25-2019, 04:33 PM.- Own Opinions Only -

Mic and instrument cables act as low pass filters at high frequencies.That makes it easier.

IIRC some EV mics have hard plastic screens. H'ray for EV!This isn't the future I signed up for.

Originally posted by Chuck H View PostMy thinking was that since "touching the mic" has been a common denominator in the problem often enough that (maybe) some clever manufacturer could have started coating the screen with insulative material or use a secondary plastic guard or some such. I hate spit guards, but I use them. I bought a big, fat bag of them after my shock and changed them every so often when they got smelly or whenever someone of questionable oral hygiene used my mic

Originally posted by Chuck H View PostI have to admit that the EV mics have been a great thing for the band on a budget. Good performance and (it would seem) good design considerations. But I'm old school and this was over twenty years ago. Everybody knows how to manage the 58's and 57's. Sound guys, odd stand in players, etc. Any musician with even a little nerd trivia can reference famous recordings done with those models. So that's what I used. My singer had a top end EV mic that he was very proud of. It wasn't as durable as the SM58 (you can use those for carpentry) but performed a bit better overall really.
First PA outfit I got going around here, the boss man came up with a dilly of a mic, a very old and rare EV ribbon which he wrecked twice by using it in a kick drum. EV made him an offer to trade for any dynamic mic they made short of an RE20, because they wanted it for their museum and couldn't bear the thought of dingbat busting it one more time - does he ever learn? NO! EV makes good stuff, not to be sneezed at.This isn't the future I signed up for.
