I am working with a PreSonus Series III 32 Board.
One of my Aux Mixes (Aux15) is "pegged" in a full clipping mode (like it is in a full feedback loop)
When I select that mix it has no inputs and every channel is muted and the output is muted too.
But when I select any Matrix Mix it sees that Aux Mix at full bars and in full clipping mode.
Any tips on how to figure out where the signal is coming from? Any way to trouble shoot this?
