I'm pretty sure that this device doesn't amplify and it also cannot give
the phantom power to a connected "real" condensor mic because there is
no power that comes out of the Line-In-plug of the AJB.

"My" solution for mic-on-AJB is:

- self-made amplifier with 9V battery
- electret condensor mic (for ex. Sony ECM 907)

By now, I only tested my amplifier with cheap mic capsules and the
result is not so good. I'll try the sony mic when I bought one. ;-)

Bye, Uwe.
