No. Ultranet is a completely different network protocol specific to Behringer. It is completely different from both AES50 and Dante which are/can be used on the X32 range. The only things that work with Ultranet are the P16 range of monitoring devices and the Turbosound iQ speakers.
Thank you Richard, yes, I connect my iq to the ultranet; but is the electrical interface compatible? would it be possible to create a Virtual souncard ultranet with the behringer proprietary protocol? Or is it necessary to create a hardware interface?
No nothing about Ultranet is compatible with Dante, AES50 or any other digital audio protocol. The only thing that is similar is that they all use a variety of Ethernet cabling and RJ45 connectors.
The only other device that might be of interest is the P16-I which converts 16 analogue and ADAT audio inputs into the Ultranet digital format. Unfortunately at this time there isn't an analogue out version which some people have requested before now.
