I am trying to hook up four PC condenser (aka electret) mikes together to input into my PC. A cheap mixer from Radio Shack would be ideal, but all mixers I have looked at are for dynamic mics only. Could anyone suggest a circuit possibly? I am quite a noob and cant easily tell you the mics specs, ie. impedances, etc. -just that they are all the cheap PC mics+headsets.

thank you very much,

curtis.

 

you have to build one...you'll need knowledge on preamp circuits

Probably you could modify the cheap RS mixer.
Add a resistor and cap to each input to power/dc isolate the mics.
You might add another cap and resistor to isolate this added circuitry.
