Multi-Zone Setup Assistance
Please see attached diagram. I have a five zone setup for my main floor in my home, primarily run by my Onkyo TX-NR656 AVR (denoted via Zone 1) using the AVR Zone 2 line out. I prefer Onkyo products am looking for assistance in how to get volume control for the other zones via the Onkyo iOS app. I am fully aware that the app has some limitations, but it does work for my needs. I was even able to use an HDMI/SPDIF converter to extract audio from my Amazon FireTV to match Zones 2 and 3, but of course, I am running short of power and control for Zones 4 and 5. Any help is greatly appreciated!
