GoPro HD Hero 2 external mics at DVinfo.net

Anybody use the external mic input for the Hero 2 yet? Any ideas for a cheap stereo mic or is it worth trying to find a 5pin xlr to 3.5mm adapter to fit a more expensive stereo mic I already have? Can the Hero 2 handle a pro mic or is it going to be to hot for the device? I'm trying to come up with an idea of a mic I can place in a formula style car that won't take up too much space and plug into the Hero 2 and still be better than the Hero 2 on board mic. I was considering the Audio-Technica - Pro-24CM for around $60 but it gets mixed reviews. I have and old Audio Technica AT825 which is a good mic but it has the 5 pin output which I have a 5pin to dual 3 pin xlr y cable to get into my regular cam. I was thinking about just buying a dual 3 pin female to 3.5mm to put into Hero 2. This may work but the car is going to be cluttered with cable adapters. I know there are other methods like getting a dedicated audio recorder which the mic will plug directly into and then you can sinc in post. Any help would be appreciated.

GoPro has AGC (auto gain control), no low voltage to power a mic and very poor audio record even from ext mic, so is very limited.

Grab a tiny Zoom H1 (under $100) and run you lavs or ext mic into that, sync in post to the GoPro internal mic.

This what i do.
