The Avantis cannot function as a “surface” for a DLive Mixrack.
If you wish to connect a DLive Mixrack to the Avantis to share I/O, there are a couple of choices. First, you can connect the two systems together using matching Madi, Dante, or Waves I/O expansion cards in each system. It sounds like you already have Dante cards installed in both systems, so this is probably the easiest method. Route the needed IEM aux sends from the Avantis over Dante and into the DLive over Dante which will then be sent out over the analog outputs to the IEM transmitters already connected to the MixRack. You’ll likely need to change the routing on the Avantis, Dante Controller, and the MixRack for all this to work however.
Second, you can connect the two systems together using GigaAce. This will require a GigaAce card to be installed in the MixRack (or Surface) that you connect to the Avantis. You cannot use the built in GigaAce ports on the MixRack/Surface for this purpose – it will require an GigaAce I/O card. If you are not using the built in SLink port on the Avantis, the MixRack can be connected to that port. If you are using the SLink port for something else (connected stage boxes, or ME system), then you’ll need a GigaAce I/O card installed in the Avantis as well.
