Perhaps he's thinking about phantom powered mics?

If I'm guessing correctly and you are dealing with mics then what  
you'd want to do is preamp the mic to a line level and then do  
whatever routing and mixing you need at line levels. You can read up  
on phantom power with some web searching, in a nutshell many but not  
all pro mics need 48v (at very low amperage) going *into* them or  
they won't function. You need some device to supply the phantom  
power. You could use a stand alone preamp or a mixer strip channel  
with it's own insert connection to pull the signal from. The preamp's  
line out  won't be 48v!  You can power a mic needing phantom power  
with a box that just does phantom power but you'll have mic level out  
and I'd think it might make your concept work better if you deal with  
only unbalanced line level signals.
