PreSonus Audio supports the use of Approved AVB switches connecting CS18AI and RM mixers, or StudioLive AI Console mixers with AVB cards on the same network topology for audio communication. It is important to note that at that Dante does not listen to the AVB streams, but as long as all firmware is up to date in the approved AVB switch you use, Dante traffic will flow correctly through these switches and is supported.
If you are using 3rd party AVB technology with StudioLive AI Dante Mix cards, please check with your manufacturers to verify that the use of their AVB devices will not interfer with Dante audio traffic.
