Does A1-MR support AirPlay 2?

We considered Airplay 2, and will continue to keep an eye on it for future products or updates. At present though, the A1-MR includes support for only Airplay.

While Airplay 2 allows grouping of Airplay 2 devices in the Apple Home app, to allow streaming audio to multiple rooms at once, we've already built out advanced multi-room grouping features through the Audioengine Connect App. And in our implementation, these features extend not only to Airplay on iOS and MacOS, but can even be used for non-Apple devices which don't support Airplay or Airplay 2.
