I have a 2700 and I can't see where to deactivate or turn off the Zone 2 :( When you press zone 2 or zone 3 on the remote, you’re switching over to that zone and can control it with the remote. When you press either zones, you can press the power off button to turn it off. You should also be able to go into the receiver setup and disable those additional zones. Or download the HEOS app and you can turn it off there too.
