Hi,
        I just received my MicroTrack from Core-Sound.
I would just drop a quick note about the noise floor of its
preamplifiers. The web page
http://home.rustradio.org/~rdvdijk/microtrack/ shows strange noise
spectra on the 1/4" inputs, different for the two channels. My unit
has the same figures but only when nothing is attached!

By inserting a condenser microphone those strange noises disappear
and the noise spectra become flat at a level lower than with nothing attach=
ed.

Next week I should be able to post some more comments.
Gianni
