I tried it this morning and the bass and treble settings are universal.
Aw, man...! That's too bad. The fact that Bass & Treble adjustments were up in the Input Configuration menu gave me hope that they could be set on a per input basis. Oh well.
Jeff, are you sure they're global settings? I ask because the other items in that menu are not global (I mean, "Coaxial 1" can't be a universal setting for all inputs).
