bit, or the actual stereo or multi-channel DSD layer according to the user's selection.
The three choices of reproduction to be found in the SACD setup menu are:
•
•
•
RedBook CD
The idea of SACD was always backward compatibility. Placed in a standard CD or DVD player that
cannot read SACD, the RedBook CD layer would be played instead. Placed into an SACD capable
player, the SACD stereo layer is automatically chosen.
The DMP ships with this latter option as default. Without entering the setup menu, DMP will play
the stereo SACD layer when connected to an authorized PS Audio DAC. If connected otherwise,
DMP will output a downsampled PCM version of the stereo DSD layer, at twice that of RedBook
CD: 88.2kHz/24 bit.
Multi SACD
Some SACD have more than the two basic layers (RedBook and stereo DSD). This third layer
contains multi-channel DSD data for up to 6 channels of audio. DMP is capable of playing all 6
channels of DSD when three stereo PS Audio authorized DACs are connected via its I2S outputs
if this mode has been selected.
If only one authorized PS Audio DAC is connected via its I2S outputs, and Multi SACD mode is
chosen, the first two channels of the multi-channel layer will be reproduced in pure DSD. These
first two channels are typically the left and right front channels in a multi-channel recording. They
are typically mastered differently than the stereo layer, and are specific to a multi-channel recording
and should not be connected to unless you specifically want these two channels.
If DMP is connected via any of its outputs to a non-authorized DAC, choosing the multi SACD
layer will provide the same left and right multi-channel information, downsampled from the SACD
multi-channel layer in PCM at 88.2kHz/24 bits.

In non-PS Audio connected
DACS, choosing an SACD
stereo or multi-channel layer
will provide a downsampled
PCM version at DMP's outputs.
This
version, output at 88.2kHz/24
bit, is generally superior to the
RedBook CD layer.
When connected to a PS
Audio authorized DAC, the
choices will provide either
