Does 140 pro + 140 pro without pre-amplified output board = 210 pro

   Thanks, Anan. I will have a 140 and 220 simultaneously for a while, which will be kind of fun and I may comment but won't be able to do a 210 v 220 comparison.  Frankly, I'd be curious on that one as well--same power, but dual mono.
