Great news - the vocal doubling effect was in the preset I was using as my default. It's not listed as a double, but it's in here. I changed the preset and now it's normal!!! Yay
The little mixer works SO well - I had 2 weddings and 2 club dates this weekend, so, to quote professor Henry Higgins ... " it's second nature to me now - like breathing out and breathing in" (My Fair Lady)
Unless its a cocktail or dinner job - I use the Bose with the paas. 2 trips to car, ten minute setup - light and beautiful.
