About Zones

Assign Zone creates a logical ‘zone’ for all devices in the selected subnet, and another zone for the remaining devices.

Standard multi-subnet domains require at least one unicast clocking device in each subnet, to distribute the network clock between the subnets. Zoned domains, however, do not have the same requirement – unicast clocking between the zones is not mandated.

This enables the zones to be clocked independently by a shared non-local clock source – for example, GPS – which in turn enables audio in geographically-separated zones to be fully synchronized.

In the example below, one device in each zone is acting as a boundary clock, taking their clock from a GPS-enabled device, and the rest of the devices in each zone are synchronized to the local boundary clock.
