So, in theory you could use a switch that supports port mirroring, connect that between the MixRack ACE in port 1 and your MixController, and use SPAN-out ports to feed the ME1’s?
If this were true, fixed MixRack users that already have Dante installed in port 2, could also benefit from ME1 without a major investment in an extra Dante option card + ME-U.
I would then be interested, for instance
