What plans are there to have audio sample rates above 48 kHz as well as mixed sample rates on an A2B network?
The technology supports programmable sampling rates at each node in the system, from 1.5 - 192kHz. You can have any combination of sampling rates in a single system, but the superframe rate is 48kHz. This means that you need to properly care for slot assignments when programming the A2B transceivers. For example, if you are sampling at 96kHz on one node, you'll need to have two slots assigned on the bus for that node such that each superframe transports two samples at the 48kHz bus rate.
