Bluesound Professional products do not support Apple AirPlay 2, Bluetooth or Google Chromecast for security reasons. However, we have customers who require these connectivity options. The NAD CS1 Endpoint Network Streamer is a wireless interface device which supports all of these wireless connectivity methods and more. Its analog output can be connected directly to the analog input on Bluesound Professional streamers or streaming amplifiers, but for maximum accessibility, the output of the CS1 can be connected to the analog line input of the HUB to allow for wireless streaming via AirPlay 2, Bluetooth or Chromecast to any Bluesound Professional device on the network.
