Audio clock domain

All Dante devices on the same network or VLAN segment must operate within the same audio clock domain. A system wide isochronous audio clock is automatically generated. A NION or CAB will always receive its audio clock from Dante.

However, if NIONs are operating within an XDAB cluster, the behavior is different:

• In the XDAB master, the Dante clock can be taken from the Dante network as a Dante slave or the XDAB clock can be supplied as the Dante master. Normal Dante clocking concepts apply.
• In XDAB slaves, the Dante clock will always be taken from XDAB and will not be taken from the Dante network audio clock directly. The clock will be taken indirectly from Dante via the clock generated by the XDAB master.

Logical separation of the network

Use of VLANs creates a logical separation of the network that causes the VLAN segments to behave as if they are physically separate networks. Use of the term VLAN also applies to physically separate networks.

Each VLAN segment must therefore have its own Dante master.
