Somewhat arbitrarily, these zones are defined below but may be used in other ways. The important consideration is
that there is a priority hierarchy – streaming activity on a zone higher on the list, will be treated as a higher priority
than a zone lower down on the list – with music being the lowest priority.
1. Priority
2. All Call
3. Zone 1
4. Zone 2
5. Zone 3
6. Zone 4
7. Zone 5
8. Zone 6
9. Music
“Expanded” zones can also be enabled, in Basic Settings → Multicast, allowing up to 50 zones in total. These have the
same behaviors as the basic zones but are hidden by default to simplify the interface.
