The Pre Box RS Digital combines all the features of the DAC Box RS with selectable solid-state or tube output stages.

As in all of Pro-Ject’s top-class digital products, they use PCM1792 DAC chips from Texas Instruments, but a new feature in the Pre Box RS Digital is its dual chip mode to achieve ultimate fidelity. As a selectable feature a second DAC chip from Texas Instruments is on board, that can handle up to 32bit/384kHz.

Included on the Pre Box Digital RS is a headphone output with selectable impedances for perfect matching with your headphones. 

The Pre Box Digital RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with flexibility to use a wide range of digital and 1 analogue sound sources. 

Combined with the Pro-Ject CD Box RS the Pre Box RS Digital will give outstanding sound experience, because of a I²S connection provided via RJ45 that offers jitter-free disc playback.
