The AR2412 (and AB168 and AR84) stageboxes use A&H’s proprietary dSnake protocol. They’re only compatible with GLD and Qu mixers. To get signals from an AR2412 into Dante you’d need to use a GLD console with a Dante expansion card, or some other expansion card to get multitrack into a computer running DVS (or just a PC running DVS if using a Qu, but there are other issues with that eg finding the right DAW and clocking,) or a GLD another expansion card eg MADI, and then a MADI-Dante Bridge.
In any of these scenarios though, you still wouldn’t be able to control preamp gain and +48v through the Dante network, as the preamp control is part of the dSnake protocol, which is closed source. It would need to be controlled through the GLD\Qu mixer.
