I want line outputs 1-2 to mirror the main outs in all playback situations - even when not using my DAW (in my case Pro Tools 11). For example, if I'm playing a track on iTunes, I want to be able to hear it on my hi-fi speakers as well as my studio monitors (and ideally be able to switch between the two and mute one of the speaker sets if necessary). In my current setup, I have my Technics amp hooked up to the Quantum via line outs 1-2 but am not getting any signal through them.
Any help/advice very gratefully received. Thank you!
