Hi Thomas,
Sorry to dig up this oldish discussion and if I missed some of the ideas..
but it's actually quite interesting.
No problem - it's still not solved on our side, as the two solutions so far
were deemed too expensive for a test setup by my higher-ups.

Sadly, it has to be inside. The bigger machine it's to be mounted in is
itself stationary and outside, and not exactly at ground level. There's
sadly no feasible way to have our stuff outside of the enclosure. If it
were, the cables would be on the order of ~100m and the stuff outside the
machinery would need to be secured against weather and - more importantly -
humans that have nothing to do with it, as it would be publicly accessible.
As there is a climb involved, repeatedly turning the machine on, checking
the levels, turning the machine off, climbing up, adjusting the levels,
climbing down, turning the machine on, ... is also not feasible.
Thanks,
Thomas
The whole setup will be mounted at a remote location inside a larger
machinery for audio surveillance of said machinery (fault detection
etc.). The larger machinery of course may not be running while opened to
install our setup, thus setting the gain has to be done remotely.
The PC in this setup has an x86_64 CPU running Ubuntu 12.04 LTS, but the
case is too small for PCI(e) solutions, doesn't have firewire, so the
only option is USB.
Does the audio interface *have* to be inside the machine as well? What I
mean is Couldn't you just have the mics in the machine and the audio
interface outside (and accessible) so as to possible set the gain, fine
tune, turn on/off etc.?
