I have a T8s and recently ran into a situation where I needed to send 6 channels to MAIN and phones, and 2 channels (click track) only to phones (i.e. they should not be heard on MAIN/FOH). I couldn't easily find a way to do this. Would anyone know if this is possible? If this is not supported, I'm guessing the only other option would be to send all channels to AUX out and mute the two click track channels on MAIN. Then connect the AUX out to a separate headphone amp.
Would appreciate your thoughts.
