I am desperatly looking for some discrete Onkyo codes to select different inputs from the amp A-9155. The original remote only offers input+ and input- which obviously is of no big help in an install. These amps are given so I had no choice selecting a different one. Anyone got an idea of how to select a dedicated input by IR? Customer will have PRONTO TSU9400s and one RFX9600, FWIW.
