Pro-Ject Box Design DAC Box RS2 DAC

The DAC Box RS2 features a very sophisticated digital stage, with a dual-mono configuration of the high-class ESS Sabre ESS9038Q2M DAC chips, featuring upsampling technology. Unlike most other designs, it boasts dual DAC chips and separate signal paths for the left and right channels. This allows for the finest conversion possible and support for digital transmission up-to 32-bit / 768kHz PCM and DSD512 over USB. There's also full authorisation and hardware/software support for Master Quality Authenticated (MQA) audio files, and Roon Tested certification for quick integration into a Roon-based system. To handle all this complexity, the DAC Box RS2's USB input is processed by a powerful multi-core XMOS microcontroller with advanced Multi-Core RISC architecture. The CPLD MAX II (Complex Programmable Logic Device) Altera is used for re-clocking, which together with the XMOS microcontroller brings high-quality processing of both traditional and MQA source material.
