You can play audio files from a USB flash drive, external USB hard disk, or a network drive. These options are ideal if you already have a digital library of CDs or music files.

On a USB flash drive or USB hard disk the files can be organised into folders, giving you one way of classifying your music; eg by Artist.

On a NAS drive you have the option of running a media server program, which will catalogue your music library and give you the option of organising it in different ways; eg by Artist, Genre, Album, or Composer. One free option is MinimServer; see http://minimserver.com/.

To play audio files from a USB flash drive or hard drive

  • Connect the USB drive to the USB-A input on the SP25. 

The USB drive can contain folders and music files in any of the popular formats; see Technical specification for details.

  • Use the Prisma app to browse, play, and control the music.

To play audio files from a NAS (network) drive

  • Connect the NAS drive to the same network as the SP25.

The NAS drive can either contain folders and music files in any of the popular formats, or it can run a music server. See Technical specification for details of the supported file formats.

The SP25 can use Chromecast to connect directly to a music service that supports Chromecast, such as Spotify, Deezer, Tidal, or TuneIn Radio. The music is streamed direct to the SP25; once set up you can use your phone to make calls, or play other audio.

With a phone, tablet, or Mac/PC you can also play the audio wirelessly to the SP25, using Bluetooth or AirPlay (iOS only), so the sound from any apps you run on your device will be played through the SP25.

Although you can stream music over Wi-Fi, for best results connect the SP25 to your home router via an Ethernet cable. If necessary, use the Google Home app to configure the network settings on your SP25.

  • Click the Cast button within your music service’s app and select the SP25 in the device list.

To stream using AirPlay

Use AirPlay to send audio over the network from your Apple device to the SP25. AirPlay is only available on Apple devices.

Use Bluetooth to send audio directly to the SP25 from your Bluetooth device using Bluetooth connection. You don’t need a network to stream using Bluetooth.

To stream using Spotify Connect

The SP25 supports Spotify Connect, which means you can stream music directly to the SP25 from the Spotify music service over your network, using the Spotify app on your desktop or mobile device as a controller.

Use your phone, tablet, or computer as a remote control for Spotify. Go to http://spotify.com/connect to learn how.
