Pro-Ject Stream Box DSA

Pin It

Pro-Ject's all-in-one, high-end solution to your media streaming requirements! Featuring 24-bit/192kHz streaming capability, Internet radio and a built in audiophile-grade stereo power amplifier, the Stream Box DSA is fully capable to function as the centerpiece of a system.

The Stream Box DSA adds an internal amplifier allowing it to function as a self contained digital audio center - simply add speakers! It can act as a D/A Converter for other digital sources using USB, Coax or Toslink inputs and as an analog preamp for up to two analog sources.

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

NetAPI interface is implemented using a proprietary, Pro-Ject designed app, available for your mobile devices using the IOS or Android platforms. From the free app, all functions are controllable and will be able to operate all IR-controlled Pro-Ject Box Design components. 

Stream Box DSA can function in a multi-room environment by using multiple units. Each zone is capable of playing different music simultaneously and individual playlists can be created "on the fly." Selection of music can be done centrally from a computer or locally using a tablet/smartphone using Plug Player. Control of volume is done with a local amplifier.

A 3.5" TFT color display shows unit status as well as album artwork in high resolution. Front and rear USB inputs are Apple licensed and provided for storage devices or the digital connection of iPods, iPhones and iPads. The Stream Box DSA provides streaming via Ethernet or attached wireless aerial. 

Internet radio access is provided using the vTuner platform, allowing for both local and international stations as well as being applicable for music services such as Napster, Rhapsody, Sirius, Pandora and All functions are accessed via the supplied IR remote control.
