I think it depends on what you mean by “use the ar2412 with the dante i/o card”.
I often use an AR2412 connected to the SLink port on the SQ and then also connect to a Dante network with my S-Dante card. If you are asking if you can patch channels from the AR2412 to/from a dante network, you absolutely can if you have the 2412 connected to the SLink port and an S-Dante card in the I/O port.
I use this setup often at multiple venues with both an SQ6 and SQ7.
If you are asking if you can connect an AR2412 directly to a Dante network (without an SQ) that would not work. The 2412 must be connected to the SLink port on the SQ and then can be patched to/from the Dante network (with the S-Dante card) through the SQ’s I/O page.
