All works great, I can switch back and forth between speakers A and B in the control room. A second set of speakers are connected to Line Output 3/4 with a TRS jack and connected to device port UR44 Mix 2L & UR44 Mix 2R in the control room. So my main studio monitors are plugged into “main output L/R” and connected to device port UR44 Mix 1L & UR44 Mix 1R in the control room. But I’m puzzled regarding adding a third set of monitor speakers.

I’ve been the using the UR44 for a while now and like it very much.
