There is a very good single chip preamp by analog devices. Their part number is SSM2017. It's cost around $3 or $4. You'll also need a DPDT switch, (2) 9 volt batteries, 5K ohm pot, mic input jack and output jack and a piece of circuit board. All except the chip can be obtained from Radio Shack.
The chip can be ordered from any real electronics store. Circuit info can be obtained here...

Page 6 is the circuit you want. Rg is the 5 KOhm pot. To get +9 and -9 volts fron the batteries, you will have to put them in series and center tap them.

The alternative is to go to and order a mic preamp for approx. $100 .


: Ok, someone below told me that my mic trouble was not because of the DAC in my sound card, but because it's not being preamped.

: It was meantioned that I could MAKE a preamp for less than $15, but I don't even know exactly what a preamp actually is, let alone know how to make one!

: Get someone give me the lowdown?
