The RIG is before the jack 1/4" ?
everything can be justified...
I think i get what you mean, but still i believe you got something mixed up there.
As described, the "Rig" is the whole Signal Chain. Try to see it as follows: You have your traditional Valve-Amp, Effects and Cab on your stage, ready to use it. When you choose a different "Rig", the Kemper acts as if you would remove all your gear from the stage and get a new Amp, Effects, Cab, etc. on there. Therefore, even the first Input Jack of the signal chain (reflected by the Input Settings) changes and is part of the whole thing that is called rig. The Rig-Menu however still manages the whole thing. Regardless of whether you carried your Marshall or Fender to the stage. So it would not make sense, that this menu is part of the signal chain.
