So, I was able to connect up the K-XR tonight after unboxing and shelving the beautiful chunk of aluminium on Thursday. The initial power-up is supposed to automatically trigger "setup mode" in order to activate and name the inputs. Not so on mine. The two "buttons" are perhaps pressure or heat sensitive, but are not typical push-in/out style. The right button is supposed to be used to force the unit into setup mode, but not so on mine. On the good news side, the two inputs connected right now both play music and it sounds pretty sweet so far. Still, I cannot name the inputs and de-activate the other six unused ones, and as it turns out the main function of the right button is Mute but not so on mine. That button may be "stuck" or something else may be wrong but I cannot seem to get it to work properly. For the price of this thing, I have to say I am fucking pissed. Tomorrow I will speaking with the shop and perhaps Ayre.
