MK171 Mic Replacement

Hello,
I just go my MK171 kit and I would like to replace the mic that is onboard with a mic jack. Has anybody tried this?
Thanks,
Asok

MK171 requires signal from an electret mic. Dynamic mic signal is too low.

So, I would need a powered mic?

Yes, that is correct.
Most multimedia microphones are electret types.

Great! The is what I have. Thank you for the help. If this works, I think I might be able to sell a few hundred of them.
