I thought i posted this before but i cannot find the post. is it possible to bring IP audio (Dante) into the mixer on a Carbonite Ultra?
You will need to Embed and Dis Embed To and From the SDI where you can pull the channels of Audio from.

Those products would be examples of solutions to get the Audio in and out of the Ultra to and from Dante.
