Trigger cable for sources in companion mode?

[mrxad81]

This is for data communication, the link is not bi-directional, it always goes one way. If you use a Companion source, sound will travel from companion to master, the trigger cable will send source change/volume change etc. as commands from the Master to the Companion.

Thank you.

Is there a way to use this scenario and also another trigger input from my AVR (as I use the trigger input actually)?
