Steve,

I don't have the equipment but it responds to device code 48 for most commands where just about every other(older) receiver uses device=16. It probably can be set in the setup routine to respond to the legacy commands if desired.

A short answer to your question is that all the inputs should have discrete commands and probably has all the soundfield/DSP commands see

That is a collection of most Sony codes. Just click on 48 or receiver to see the commands.
