    A True High-Performance All-Arounder

    The advanced Pre Box DS2 Digital is a universal and very flexible preamplifier and D/A converter of the highest class. It is a true high-performance all-arounder featuring phono, digital, and line-level inputs. Due to its class-leading audio performance Pre Box DS2 Digital is an ultimate high-end bargain.

    High-End AK4490 DAC

    Pre Box DS2 Digital features the most advanced technology in its price class. The sophisticated AK4490 D/A converter, from Asahi Kasai Microdevices, together with the complementing sample rate converter (AK4137), are responsible for outstanding resolution, soundstage, air and imaging.

    The built-in D/A converter AK4490, from high-end manufacturer Asahi Kasai Microdevices, has five different digital filters which let you shape the sound to your preference. The ability to control the upsampling of all incoming digital signals to PCM 768 kHz / DSD256 with the Sound Modes button gives you the possibility to shape the sound to your personal preference. Three different sound modes and five different digital filters at your hand offer no less than fifteen individual listening experiences!

    Lots of Connectivity

    The Pre Box DS2 Digital gives you plenty of connectivity for your source components. An MM and MC capable phono preamplifier as well as a line level input for any other analogue source round up this incredible one box solution. Four analog outputs (fixed, variable, subwoofer, headphone) together with S/PDIF optical digital, asynchronous USB and aptX Bluetooth make Pre Box DS2 digital one of the most versatile audiophile preamplifiers on the market.

    Five Digital Filters

    Pro-Ject's Pre Box DS2 Digital doesn't just play your music files, it also lets you decide how you want them to sound. With a total of five digital filters available onboard, the sound can be shaped precisely to your liking.

    The filters consist of Super Slow Roll-Off (no echo, natural sound), Short Delay Roll-Off (minimal echo, original sound, acoustic tone), Slow Roll-Off (minimal echo, original sound, traditional tone), Short Delay Sharp Roll-Off (post echo, bass sound, acoustic sound), and Sharp Roll-Off (pre and post echo, powerful sound, traditional sound).

    In addition to the digital filters, the DAC Box DS2 Ultra also includes three selectable sound modes: Upsampling, Conversion to DSD, and USB Upsampling Bypass.

    Perfect Match for Pro-ject Box Series Amps

    The Pre Box DS2 Digital is a feature rich, pure high class audiophile preamplifier with convincing sound and elegant looks. Together with a Pro-ject Amp Box DS2 or two Pro-Ject Amp Box DS2 Mono power amplifiers, you will unleash even fuller, lusher and more detailed sound than heard from any other combination in this price range.
