The mic pre amp described here is designed to connect a small electret microphone and uses an integrated circuit type NE5532. As you can see, this scheme is very simple. The use of a dual operational amplifier type NE5532 is a large part in simplicity, although it was quite possible to simplify even more by using a single transistor.
