The Atoll Électronique ST300 Signature is a network player/streamer and preamplifier in one device. Streaming internet radio, Spotify Connect, Tidal Connect, Qobuz, Deezer and your own music collection is possible. In addition to streaming, the ST300 Signature has several digital inputs and analog inputs. The ST300 Signature can be used as a pure source network streamer with a fixed output or as a streaming preamplifier.

The Atoll Électronique ST300 Signature combines the convenience of the ST200 Signature and the sound quality of PR300 Signature in one housing. The result is a versatile device with various streaming options, digital connections for your television, for example, and analogue inputs for your CD player or record player, for example.

The basis of the Atoll Électronique ST300 Signature is, of course, music streaming. The ST300 Signature features internet radio, Spotify Connect, Tidal Connect, Qobuz, Deezer and streaming of your own music collection from NAS (DLNA and UPNP) or USB drive.

Atoll Électronique has its own application for internet radio, Qobuz, Deezer and streaming its own music collection. The app is available for free for both Google (Android) and Apple (IOS). The app is clear and allows you to easily find your favourite music or internet radio station. It is possible to save favourites, internet radio stations, or create a playlist from your own music collection. In addition to controlling the streaming services, it is also possible to choose the input/input of the preamp and adjust the volume.

The streaming services Spotify Connect and Tidal Connect can be used via Tidal's own and Spotify's own apps. This way, you don't have to get used to a new app, but you can stream directly from the apps to the Atoll Électronique ST300 Signature. It makes it easy to keep your own favourite artists, albums, songs, and playlists.
