Hello, I'm new here with my new xr12. I love it. I'm using it only for home audio along my old analog line, A-B testing. My first scene is to realize a 3 way crossover for existing 3 way apms. In order to do that first I wanted to create 3 separate stereo lines. When I tried to mute Main outs I observed that the phone out is muted as well. What I'm doing wrong? Please advise. Scene attached.
