I'd like to be able to split the LR stereo channel so I can have a separate mix and EQ on each to use it as another aux, sub feed, matrix out, whatever.
And this should happen automagically as part of a "template" preference which is pre-configured for "all-mono" system configuration
A significant percentage of professionals who use the DL1608 will be using it in mono mode, for reasons which have been discussed ad infinitum on the old Mackie forum.
A template which switches all routing to mono would also provide more efficient use of the available DSP.
It would be pretty cool to have a "Mains Mode" selector where we could choose between configurations like LR, LCR, LRM (LR + mono/sub), Dual mono, and Triple mono ... aux 1 or 6 being used for the third output channel. I personally could have seen use for all of these except LCR.
