SACD Compatibility Notes - TimeForDVD.com

The Super Audio CD (SACD) format specification allows for an optional hybrid CD layer that conventional CD players and CD-ROM drives can read for backwards compatibility with the existing one billion CD playback equipment worldwide. Here's a summary of the major variants of the SACD disc and their implications in terms of SACD/CD playback equipment compatibility:

Hybrid Multi-Channel: This hybrid SACD has a high density layer for high resolution multi-channel and stereo DSD recordings, and a hybrid CD layer for backwards compatibility with existing CD players and CD-ROM drives. The high density layer contains a multi-channel DSD recording and usually a stereo DSD recording as well. The multi-channel DSD recording requires a multi-channel SACD player and a multi-channel audio system for playback. The stereo DSD recording can be played back by a multi-channel or stereo SACD player and only requires a stereo (2-channel) audio system. The hybrid CD layer can be played back by any audio CD player or CD-ROM drive.

Hybrid Stereo: This hybrid SACD has a high density layer for high resolution stereo DSD recordings, and a hybrid CD layer for backwards compatibility with existing CD players and CD-ROM drives. The high density layer contains a stereo DSD recording. The stereo DSD recording can be played back by a multi-channel or stereo SACD player and only requires a stereo (2-channel) audio system. The hybrid CD layer can be played back by any audio CD player or CD-ROM drive.

Single Layer Multi-Channel: This single layer SACD has a high resolution multi-channel DSD recording and usually a stereo DSD recording as well. The multi-channel DSD recording requires a multi-channel SACD player and a multi-channel audio system for playback. The stereo DSD recording can be played back by a multi-channel or stereo SACD player and only requires a stereo (2-channel) audio system. This disc cannot be played back in a conventional audio CD player or CD-ROM drive.

Single Layer Stereo: This single layer SACD has a high resolution stereo DSD recording. The stereo DSD recording can be played back by a multi-channel or stereo SACD player and only requires a stereo (2-channel) audio system. This disc cannot be played back in a conventional audio CD player or CD-ROM drive.
