Wasn't there a specific software this works for?
In other words, (not knowing the actual numbers, these are used for examples only) if I have version 1, and one of the later upgrades allowed this side/surround option by going into the AUX and defining them, would mine version 1 not work?
I don't know the version yet (have not connected it to a screen) but I will go through the process with trying to set it up.
My bet was that, example again, version 1 did not have the ability to be able to use the AUX for sides or subs, even though the unit had the outputs for them. Then, in later version, Proceed/Madrigal made these available with a software upgrade.
