Hi Bachus.
Sorry but I can't answer you either. I don't have the Mic Input boards installed in my machine so all I can do is just access the screen.
Here's a screen shot of the Mic / Vocal section.
That said, I would assume you can run whatever plug-in you want on it, but I cannot verify this. There's no mention of this in the Manual either far as I know.
Regards
James
