Your BluOS player does not require Internet Access to work.
At its basic level, BluOS only requires a wireless router to communicate with other Bluesound players as well as be controlled by the BluOS App from your iOS or Android mobile device or a Personal Computer on the same network.
From here, you can configure network shares from computers and NAS drives, share content stored on a BluOS Storage Device like a Bluesound VAULT or NAD M50.2, playback files from USB drives and stream Bluetooth content to your player (BLS-KB14-401).
If you plan on ripping your CD collection using The BluOS Ripping Player' bit perfect lossless ripping process, the Internet will be required. BluOS will locate and embed metadata tag information and album artwork making the process as easy as simply inserting a CD. Without Internet access, metadata must be added manually using a third party editor.
Internet access is required to stream content from Music Services such as Spotify, Tidal or TuneIn.
An Internet connection provides essential support features including upgrade notifications and the ability to Send Support Requests directly from the Help Menu.
