Pro-Ject CD Box RS  
Ultimate CD Transport
CD Transport offers extraordinary audio quality & 24/96 Flac support!  

CD Box RS is an ultimate CD transport that gets maximum information from audio discs. Therefore it uses special Sonic Scrambling technology with „Sonic2“ output stage (RJ45). An I²S bus is used to communicate PCM audio data between integrated circuits. The I²S bus separates clock and serial data signals, resulting in significantly lower jitter levels, compared with all other communication principles, that extract the clock signal from the data stream. Sonic Scrambling technology improves linearity in multi-DAC designs significantly. 2 DACs per channel in differential mode are used to reduce DAC related distortion and enhance low level signal linea-rity for superior conversion. Even subtle details will be available without any audible distortion.  

To use Sonic Scrambling technology, it is necessary to connect both RJ45>RJ45 and a BNC>BNC clock cable to DAC Box RS or Pre Box RS Digital from Pro-Ject Audio Systems.  

Additionally following digital outputs are provided: AES/EBU, Toslink & coaxial S/PDIF.

Pro-Ject PRE Box RS Digital 

Pre Box RS Digital combines all features of DAC Box RS plus a very linear pre-amplifier with both solid-state and tube output stages, that can be selected alternatively. As in all our top-class digital products, we use PCM1792 DAC chips from Texas Instruments, but here we use 2 pieces in a dual differential mode to achieve ultimate fidelity. As a selectable feature a second DAC chip from Texas Instruments is on board, that can handle 32bit/384kHz. A high-class headphone output with selectable impedance for a perfect match to your headphones is also provided. 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. Perfectly combined with Pro-Ject CD Box RS disc drive, Pre Box RS Digital will give outstanding sound experience, because of a I²S connection provided via RJ45, that is able to give jitter-free disc playback.
