Hello from me. Carl Blare, while I'm preparing material to submit to the "How To" section of the ALPB web site, a post on building your own microphone.
I have a big question about a basic technical description that has always confused me.
The Electrical Characteristics printed with the electret microphone capsule used in my mic design says:
Output impedance: 2.2k (maximum).
That expression could mean the opposite of what it appears to mean, based on the inverse nature of describing impedance.
As the numbers get smaller, the impedance or resistance grows greater: i.e., 1-ohm, a low number, is a "maximum" impedance, practically a dead short. The higher the number, i.e., 100-kOhms, the lower the impedance. But it's called "high impedance."
So then, if the "maximum impedance" is 2.2k, what would be a "lesser" impedance?
