The speaker feed (matrix 1) has EQ you can set, and a second feed taken after that EQ (matrix 2) comes back into this computer. foya measures the speaker against that return, so whatever the EQ is doing cancels out, then shows the settings to dial in and checks them live, with no phone needed at the desk.
Test rig: play the return to a speaker
With no real speaker feed (e.g. a small mixer's main coming back over USB), the return can play out of another output here, standing in for matrix 1. Never the output foya plays into.
