• DAC Box RS2 - Digital Analog Converter - black - Pro-Ject

The Pro-Ject DAC Box RS2 is a state-of-the-art D/A converter that plays a significant role in the world of digital audio technology. A perfect partner for high-end amplifiers and loudspeakers, it is ideal for anyone looking for a modern converter with extensive digital input options and a fully balanced design.
This DAC box is based on the Pro-Ject Pre Box RS2 Digital and uses the same high-quality converter chips, but dispenses with an analog preamplifier to focus entirely on converting digital to analog signals. With its dual-mono configuration, equipped with the first-class D/A converters from ESS Sabre (ESS 9038Q2M chips), it stands out from other converters in its price class. It has two separate converter chips and signal paths for the left and right channels, enabling exceptional sound quality.

The DAC Box RS2 supports high-resolution 32-bit / 768 kHz files in PCM and DSD format (up to DSD512) via USB and is therefore capable of playing almost all available digital file formats. Its analog output is designed in both solid state and high-quality tube technology, giving the user the option of choosing between different sound characteristics.
Another outstanding feature of the DAC Box RS2 is its eight digital filters, including the proprietary "Optimal Transient Digital Filter" from the MQA developers. These filters allow for individual sound customization and extend the functionality of the device. Full hardware and software support for MQA (Master Quality Authenticated) technology is another highlight.
The USB input signal is processed by a powerful multi-core XMOS microcontroller, while Altera's CPLD MAX II chip is used for re-clocking. This combination enables high-quality processing of both classic and MQA technology.
Optimal use of this technology is achieved by combining it with the Pro-Ject Stream Box S2 Ultra and the TIDAL streaming service. In addition, the DAC Box RS2 can be connected to the Pro-Ject CD Box RS2 T CD transport system to enjoy MQA quality from CDs as well. The connection is made via HDMI with the I²S differential bus, whereby the DAC Box RS2 also serves as the master clock.
The DAC Box RS2 comes with an all-aluminum remote control and is available in a high-quality aluminum housing in silver or black. The large display on the front shows all relevant information in a structured way and the navigation menu responds very quickly, making the device easy and intuitive to use.

The Pro-Ject DAC Box RS2 is an outstanding combination of advanced technology, user-friendly operation and versatile connectivity, making it an excellent choice for audiophiles and music lovers looking for a high-quality D/A converter.

Note: Bitstream formats such as Dolby Digital® or DTS® are not supported.
