Tip: The XDAB digital audio bus is the most convenient way to exchange digital audio
between NIONs.
NIONs on CobraNet
Notes:
ƒ Processing on a NION will pause during project deployment. Therefore, a NION that is a
Conductor will stop being the Conductor for a time. The network will then automatically
transition to a new Conductor. Conductor transitions will cause momentary audio
dropouts. It may therefore be desirable to designate a non-NION device to be the CobraNet
Conductor.
ƒ Additionally, if using XDAB, clock disruption caused by a change of Conductor may often
cause the NION cluster to re-sync (re-arbitrate) the XDAB clock and will result in a
dropout of several seconds.
Use cases
Scenario 1 - Basic network
In this scenario, there are:
ƒ no XDAB interconnections between NIONs.
ƒ no VLANs defined.
ƒ no outboard audio connections, either analog or digital, between NIONs.
There is only one audio clock domain in this scenario established by CobraNet and no special
Conductor, topology or XDAB usage considerations apply.
