Pro-Ject Stream Box RS

Stream Box RS is Pro-Ject's reference audio streamer designed as an audiophile-grade 24-bit/192kHz streaming client and as a step up from the Stream Box DS net.

The Stream Box RS is capable of digital music playback from computers, Ethernet and WLAN networks, iOS devices and USB thumb drives or external hard drives. UPnP and DLNAn1.0/1.5 support are also included. Designed to play digital file formats including MP-3, ALAC, AIFF, AAC, Ogg Vorbis, and WMA9-lossless, as well as FLAC and LPCM files up to 24-bit/192kHz. In addition, the Stream Box RS supports direct streaming from portable devices and accepts streaming services like Spotify, Grooveshark etc., using Jamcast software. Additionally, a vTuner internet radio platform is included.

Pro-Ject's NetAPI interface is implemented using a proprietary, APP available for your mobile devices using the IOS or Android platforms. Available as a free download from the Apple App Store or in the Android Market these apps provide ultra-fast access and control of the Stream Box DS net from your smartphone or tablet device. From the Box Control App all functions are controllable, and the Box Control App will be able to operate all IR-controlled Pro-Ject Box Design components. In development and available shortly, is Remote Box that will allow 3rd party devices, like TV's, to be system unified and controlled by Box Control App as well.

In an effort to keep the Stream Box RS from becoming technologically obsolete, the Pro-Ject engineering team designed the Stream Box RS to accept software/firmware uploads of possible new services and features available in the future.
