Hi Guys, I?ve been playing around with three remote amps & one audio distribution unit and after 4 hours finally got them working. The problem related to me not setting the source group setting on the amps, is there a way of setting this without allocating a key (switch) to select it, as the ADU only has one output. Also one comment I?ve got about the installation instructions is that they are directed more to setting up the matrix switcher, so it might be a good idea to also provide a second smaller manual dealing with the setup of the distribution unit only? Also is there a manual for the toolkit software or is it just hands on :) Cheers & merry Xmas Stuart
