MOTM

Mark -

As a theoretical math thing, I can't help.  Paul's much better!  But 
I can say, and as others have clearly stated in this thread, that you 
can use the 410 for MOTM inputs and anything else.  I built mine with 
the resistor option for handling MOTM inputs.  With a preamp (I also 
use the ART MP) I've been able to use the 410 on pretty near 
everything I own, including electric mandolins, lap steels, and 
acoustic guitars.  You can do amazing stuff with it.

My mixer (Tascam TM-D1000) has trim pots for the inputs.  It just 
plain works.  Don't worry, buy one, you will not be disappointed.
