There's another answer from 2020 that states that NSB requires a Series III mixer, but I fail to see why that would be the case. AFAICT, both NSB and EarMix are AVDECC-compliant. That would imply they should be controllable from _any_ such controller to receive (and send, in case of NSB) data over the AVB network. There's shouldn't be any proprietary configuration format being sent from the mixer to those devices, if my understanding is correct.
Unfortunately buying them just to try it out without being sure that it'll work is a tough budgeting proposal, so it'd be great if someone from Presonus could weigh in on that.
