The StudioLive AI console's AVB and Series III AVB are not compatible with each other as they each use a different version of AVB.
StudioLive AI and RM/RML mixers can connect together through AVB with AVB-OptionCards and their latest firmware.
StudioLive Series III Products can connect together through AVB to other Series III Devices.
