Hi. I believe it depends on how to plan to connect and power Zone 2.
You cannot listen to digital sources including HDMI if:
- You use Zone 2 analog audio outputs and connect those to an external amp.
You can listen to digital sources including HDMI if:
- You use the front left/right pre out jacks and connect those to an external amp.
- You choose the bi-amp option and connect Zone 2 speakers to the "Surround Back / Bi-amp" speaker terminals
You should be able to listen to digital sources including HDMI (I can't verify this, but I'll be shocked if it's not the case) if:
- You connect Zone 2 speakers to the "Zone2/Presence" speaker terminals
