Frequently Asked Questions
How do I power it?
Electret mics with a FET are typically biased through a resistor from a 2–10 V DC supply, and the audio is taken off through a coupling capacitor.
Is it good for music recording?
Its 50 Hz–8 kHz range suits voice and sound detection more than full-range music.
