The Pro-Ject DAC Box RS is a cutting-edge, reference-class digital-to-analogue converter designed for diverse digital stereo sources. It functions exceptionally well as a USB audio interface, offering superior HD audio playback from a computer and supporting an I²S interface with a Master Clock output, ideal for pairing with the CD Box RS. This DAC also seamlessly handles other digital sources via AES/EBU, optical, and coaxial outputs, making it a highly versatile choice for audiophiles. With support for DSD up to DSD128 over PCM, it accommodates the needs of dedicated listeners seeking top-quality sound. Features Double top grade PCM-1792 D/A chip from Texas Instruments 9 Inputs: I²S, USB, AES-EBU, optical (Toslink), coax (S/PDIF) 24bit/192kHz asynchronous USB (XMOS technology) DSD (up to DSD128) capability (DSD over PCM) I²S interface for CD Box RS (sonic2data transfer Technology) with additional clock synchronisation port (BNC) 2 selectable digital filter settings Fully balanced analogue audio circuitry Tube output stage & solid-state output stage (switchable) Ultra linear & ultra low noise circuitry IR remote control included XLR & RCA line level output sockets Full metal casing in black Two DAC Chips - Two Filters The DAC Box RS supports HD music files at resolutions of up to 24-bit/192kHz (96/24 for optical inputs) in fully asynchronous mode, ensuring high precision and fidelity. At its core are two premium audio-grade DAC chips, the PCM 1792, renowned for their exceptional audio performance and usually found in high-end designs. To tailor sound to individual preferences, it offers two digital filter settings, allowing users to adjust sound characteristics to match their taste and music style. This level of customisation ensures that listeners can achieve their desired audio profile. Choice of Output Stage for Personalised Sound For ultimate flexibility, the DAC Box RS provides the option of a warm, relaxed output stage using tubes, or a highly detailed and dynamic solid-state Class A output. Both choices are expertly designed to meet the highest standards of audio reproduction. The DAC’s ultra-low noise, ultra-linear design with low output impedance prevents interference with cables or pre-amps, ensuring clarity and purity of sound. With its impressive range of features and superior audio quality, the DAC Box RS represents a high-end option at excellent value for audiophiles seeking class leading digital sound conversion.
