Default Microphone amp?

I'm not sure if this is in the right section...I'm not particularly sure what I'm asking about. Anyway...I need to be able to hook up a microphone to an RCA input. How do I do this? Do I need some kind of amplifier for the microphone?

Yes, you will need a gain stage.
Google will give you a heap of choices.

Rod Elliot is a good starting point.

But you can test first just connecting the microphone. Maybe the gain is sufficient. Costs nothing to try.

If it is an electret condensor then it will need a bias voltage also.

I second the idea of looking at Rod's mic preamp project.
