A Dynamic Microphone Soundcard Amplifier
"A good tutorial on interfacing microphones to soundcards." This was the brief description preceding Paul Loewenstein's article in the original edition of audioXpress. We think that's more to it. The author describes a microphone amplifier designed to interface a standard dynamic microphone to a soundcard or other computer microphone input with a 5V through 2.2kΩ bias to the microphone connector ring. This article was originally published in audioXpress, February 2008.
