The online documentation wasn't clear, so I took a risk. Here’s proof that the DN4816 series works with Ultranet, despite what people on Musictribe might say. I will use it to add extra outputs to my X32 rack while retaining USB audio for DAW use. Firmware: DN4816‑0 = 2.0, X32 = 4.06, X32 edit = 4.3.
