Thanks!
while this setup gets a bit complex, it will probably work OK in most scenarios.
A simple option to select the mode of the “Out” TRS jacks as either AUX bus or Main L/R as source will be a much simpler and straight-forward approach for those of us seeking to clone the Main L/R to more outputs on the mixer.
I realy wish A&H will implement it in a future firmware update.
Many thanks for your input & insight @SQuser!
