Up2Stream AMP2.0 is a WiFi and Bluetooth 5.0 amplifier board that can be applied into your existing regular audio system to make it wireless
enabled, and it is also a all-in-one solution for DIYers to make their customized wireless audio system. After connecting the device to your
home network, with our 4STREAM app, you can play music from your home NAS, USB pen drive, cell phone memory or from online streaming
services like Spotify, Deezer, Tidal, Qobuz and so on. The wireless multiroom audio system can play the same music to each room in sync or
play different music to different rooms.
