Yes, I have the stereo version, two mics on a Y-cable from the stereo plug.
When I record, I place the mics about 2' apart.

I have a volume control on mine, not sure if this is pre-amp or not

I agree, I won't do that again.  Though the mini-9V were fairly cheap and I
bought a dozen (supposedly they last 20 hrs).

Thanks for the offer - I'm going to experiment with it some more but may
eventually take you up on that.

If the input measures as a low resistance then
there is probably an internal 50/60 Hz transformer
which would imply DC should not be applied. If you
know for a fact that there is no internal transformer
then it should be possible to run the unit on 12VDC
unless something really tricky is being done.

Before applying voltage try e-mailing M-Audio;
"support at m-audio dot de"

I would be willing to look at a unit but a few decent
photos of the insides of one would probably give us
the answer.
