Our Stream Box S2 has a user-friendly app and all the features of a great modern-day streamer, including proper multi-room functionality. It offers support for high-resolution data up to 24bit/192kHz and affords you the ability to connect to multiple Stream Box S2s connected to your network. Multi-room stream quality equals CD quality (16bit/44.1kHz). For multi-room applications, this amounts to an enormous amount of data which in turn amounts to great audio quality. Zone limits are 10 (Ethernet) or 6 (WiFi) to ensure flawless data transmission at such rates. Normally high-zone multi-room streaming is reduced to MP3 quality to ensure reliability.

Additionally, two units can also be connected to build a stereo pair with assigned left & right channels. If you have active speakers you can operate them wirelessly by placing the Stream Box S2 right next to them. You can then freely position the speakers without the bother of long runs of cable, allowing for greater flexibility in larger spaces.

Three different offer additional flexibility. The line-level RCA output can be connected to a pre-amplifier for purest signal, or the dedicated variable output can be connected to active speakers or power amplifiers. The optical output can pass along a digital signal to an external DAC. The Stream Box S2 comes fully equipped with TIDAL, Spotify, Qobuz & Amazon Music. With the implementation of Shairport we were even able to give iDevice users the option to send data to the Stream Box S2. Friends of internet radio will find plenty to enjoy with TuneIn.
