Pro-Ject's all-in-one high-end solution to all 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 digital audio music system.

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

Pro-ject's Stream Box DSA 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. In addition, the Stream Box DSA 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.

NetAPI interface is implemented using a proprietary, Pro-Ject designed, 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 DSA 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 DSA from becoming technologically obsolete, the Pro-Ject engineering team designed the Stream Box DSA to accept software/firmware uploads of possible new services and features available in the future.

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 - even "on the fly". Selection of music can be done centrally from a computer of locally using a tablet or 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, and the Stream Box DSA features both Ethernet and Wi-Fi network connectivity. The Stream Box DSA provides streaming via Ethernet or attached wireless aerial. Stereo analog RCA fixed level outputs and SPDIF digital output allow for flexible interface to your amplifier or D/A convertor.

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 Last.fm. All functions are accessed via the supplied IR remote control. An outboard power supply is included.
