BOSE TS4 - Problem routing channels to AUX out

I cannot send my input channels to different aux outputs. If I send, for example, channel 1 to aux output 2 then automatically channels 2,3 and 4 are routed to the same aux out…

Really don’t know what I’m missing in pressing and turning knobs. It should be so easy and I saw many tutorials anyway. My TS4 is updated to most recent firmware with factory reset.

Please, could anyone help? :no_mouth:


I am not familiar with the Tonemach but from what I see in the manual it seems that the UX is a little weird in that you need to first press the channel button and then the function.
