Hi @Adalbert_Schulz ---- Your Trinnov is a Roon Ready device, which means that when the application is running on your network, the Trinnov should be identified as a usable endpoint by the application. This device cannot be used to host your Roon core. You will want to run Roon (or RoonServer) (or ROCK) on another computer,NAS, or NUC that meets your needs and our system requirements.
I would recommend giving our knowledge base a read it will contain all of the pertinent information necessary to understand the product and it’s functions.
