Does the A1-MR receive streamed music from your smartphone, or directly from the Wi-Fi network?

For music streamed through Audioengine Control App, or from streaming applications built into the Audioengine Control App, the A1-MR streams music directly over your Wi-Fi network. The stream will continue whether your device is taken out of range or turned off altogether.

Airplay, generally speaking, makes a connection between your source device and the A1-MR, through your network. If your device goes out of range of the network, or the application on your source that is playing audio is closed, playback will stop.
