Of course I've been looking at it from the perspective of a D2v user, and I'd say the first description that comes to mind is "simple". For example, there's no way to configure a specific type of HDMI video output format -- with the sole exception of being able to force Deep Color output to 8-bit even if your Display is willing to accept more.
So you get EITHER (1) video pass-through, meaning your Source and your Display negotiate the video format in use, or (2) automatic video, meaning the MRX finds out what the Display says it wants and sends that -- which includes de-interlacing, upscaling, input to output format conversion, and frame rate conversion if the Display says it wants something different than what's coming in as video input from the Source.
As for audio, the new, ethernet-based ARC works just fine. One highlight of these new MRX units is that they include enough processor power to pretty much duplicate what ARC can accomplish on the AVM 50v and D2v. I don't know if it's fair to see they are entirely up to that level, but there's no longer the obvious difference in correction resources as was true between the D2v and the prior MRX line.
I set the new ARC a particularly tough challenge -- poor speaker positioning (particularly for the Sub) and a listening position deliberately set up off center -- about on-axis with the placement of Left Front, and over near a wall.
The new ARC handled all that just fine; hardly worked up a sweat. Measurement is faster (needs fewer sweep tones each time to lock in) and seems pretty robust -- no network glitches or issues with it rejecting test sweeps.
The new ARC Windows application includes an entirely redone UI. Among other things you can see the Measured curves for each mic location for each speaker. And in Targets, you also get a chart that shows you how the Target curve will change as you enter changes -- i.e., without having to accept the changes first.
They've also added the ability to Print results.
I won't derail this into a 2nd MRX thread, as the bulk of discussion on these three new units should of course go over there.
But if any of the AVM 50v / D2v crowd here have questions, I'll be happy to try to answer them.
ETA: The new ARC retains the prior simplification for MRX users that MAX EQ Frequency is limited to no higher than 5KHz (which is also the default). You can lower it below that, but not raise it. This eliminates the confusion factor among MRX users as to whether the Measured data higher up than that is accurate enough to be used as a basis for treble correction.
