The T-80 is just a remote control with audio connections for the iLive system.
And the I/O sockets are freely patchable.
Remember, the input sockets are not the same as input channels… an input channel can get his signal from different sockets and this is recall-able with scenes.
And output channels or buses can send their signal to different sockets… also recall-able with scenes.
I read in one of the manuals, that input PAFL setting can override the main output mix.
not really… you can configure every output to be a monitor output and you can assign L/R to monitor then PAFL will override the L/R signal with the PAFL
but if you have outputs configured as main outputs no PAFL will override this.
Can you provide some more information on the bus configuration of your system?
Maybe you can draw a patch diagram…
btw. the diagram will not help I guess 😉
