Simple microphone preamp that can be used with 15 volt power supply? Answered

I am making a project that cosists of amplified speakers with tone and bass and i am planning on adding a 2 way input, 1 for mp3/cd players the other for a microphone, however i have to use seperate preamplifiers for the 2 inputs. The preamplifier will need to be pretty basic and simple so i wont need to include stuff like noice cancelling.
Thanks for your help


Your requirments for a mic input are different from the ones for the CD. What KIND of mic are you thinking of ?


i wont even be using the mic, i just need to add it to give more depth to my project so nothing high quality, a simple electret microphone
