Checking the "Operation Manual", which is actually fairly difficult to find, the "Line" outputs go up to +18dBu, but the "Monitor" outputs go up to +24dBu.

Since there's no dedicated physical analog I/O for "Monitor Outputs", then I think this is just a setting in DADMan? Seems like a strange way to go. Why not just make the Line Level outputs switchable between Line and Speaker level ranges, like the Omni? I am definitely considering the MTRX Studio for an upcoming Atmos room, so I am curious.

I'm not super familiar with DADMan, but could you just dedicate the outputs you want to be line outs and at +24dBu as a separate monitor profile and use those with the monitor volume all the way up if you needed to connect outboard? I guess that wouldn't allow for +24dBu hardware inserts. Also, I don't know if you can have more than one monitor profile firing at the same time, and whether this would interrupt your main monitoring.
