If you have the AEB-8, this would also apply to the analog ports of the AEB-8. > In the configuration dialog > and manual there is no such option to adjust input levels as far as I > can see.

If you have the AEB-8, you just need a microphone amplifier. You can also use a Mic Preamp with ADAT out, like the OctaMic D or the Micstasy. But this is not very alsa related, so if you have further questions, please ask me via email.
