Pro-Ject Pre Box S2 - DAC

The Pre Box S2 DAC is a digital, micro-preamplifier, that can fully unfold MQA files. {MQA means Master Quality Audio - it's a high resolution audio format used for streaming - for example Tidal.} It provides super clear digital to audio - providing your preamplifier with pure sound.

The S2 is all of 4" x 4" x 1-1/4" tall.

  • The front panel has a headphone jack {for unbelieveable great sound}, a volume knob, input selection, menu selection, and filter controls.
  • The rear panel has a USB B port, coaxial digital, fiber optical, RCA audio output, and USB micro power connection.

It is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Note: this is only available on the USB B port.

With a new proprietary clock design, Pro-Ject has managed jitter rates of unrivalled 100 Femtoseconds. This easily outperforms many renowned and respected audiophile clock generators! Jitter is critical - when digital signals are not put together with the same timing as the original, the music sounds clear but wrong. The S2 offers one of the lowest jitter rates.

  • Beyond jitter rates, noise level is reduced to -130 db. This is an extremely low number, meaning you'll never hear background noise.
  • For Roon fanatics, the S2 is "Roon Capable".
  • The headphone amp can support up to 600 ohm headphones.

There are a total of eight digital filters. The sound can be shaped precisely to the listeners liking.

Pre Box S2 Digital also has a remote control. It can also control the playback software of a computer. One can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital!
