Integrated in the RS reference range of the surprisingly effective Design Box electronics from Pro-Ject, the Pre Box RS Digital is a very complete product that combines all the functions of the powerful DAC Box RS digital audio processor plus an extremely linear response preamplifier circuitry whose output section can operate, at the user's choice, with transistors configured in Class A or with tubes (triode 6922).
This is complemented by a very high-performance headphone amplifier with adaptive output impedance for perfect matching of all types of headphones, while an analogue input allows the user to connect even a turntable. As is standard for all Box Design RS Series models, the Pre Box RS Digital uses a fully balanced architecture with both XLR and RCA input and output jacks.
In addition, it is possible to select between two D/A conversion chips (PCM1792, 24-bit/192 kHz and very musical; PCM5102, 32-bit/384 kHz and more analytical). Finally, the presence of an I2S interface with separate master clock signal output makes the Pre Box RS Digital the best possible complement to the unique CD Box RS transport mechanics by drastically minimising the jitter rate.
