Default How to measure a dynamic mic's output impedance?

For the most part, it's a lot easier just to look it up on the data sheet.


And once you know the impedance, find a preamp that makes the mic sound
good. There's little correlation between the numbers and what works
best for a given mic. If you measure the mic and find that it's 80
ohms, it might sound better wtih a preamp that has a 2500 ohm input
impedance, or a 1200 ohm impedance, or you may even like what loading
it with 300 ohms does (though it's probably not technically "best").
