DSD settings

Pro-Ject Pre Box RS Digital is capable of playing DSD64 and DSD128 files. For playing DSD files a dedicated
software player is required, which is also capable to play these files (for example JRiver Mediacenter,

Foobar2000 etc.).
Required settings for DSD:
DSD Playback Method: DoP (DSD over PCM), DoP Marker 0x05/0xFA.

DSD requires high data rate and slower computers may have problems with playing DSD.
