DirectStream Memory Player
The pure DSD output on SACD’s master layer is available through the I2S output only when
connected to an authorized PS Audio DAC. Using the HDMI cable between DMP and a PS Audio
authorized DAC, such as DirectStream and DirectStream Junior, a digital handshake occurs
identifying the safe connection. Non authorized I2S compatible DACs will not reproduce the DSD
layer of SACD to protect copyright restrictions and guarantee illegal copying of the master layer
is not possible.
DMP outputs all inputs all the time. It is therefore unnecessary to tell DMP which outputs are
connected at any one time. Multiple outputs can connect to multiple DACs if desired.
XLR
If I2S is not an available input on your connected DAC, PS Audio recommends AES/EBU (Audio
Engineering Society/European Broadcasting Union) via XLR as the next best connection. AES/
EBU is a balanced digital output stream containing a combined version of the musical data and
multiple clocks.
Using a high quality XLR data cable, connect the DMP XLR output labeled Stereo XLR to your
DAC’s XLR input.
DMP outputs all inputs all the time. It is therefore unnecessary to tell DMP which outputs are

RCA (Coax)
Many DACs rely upon coax to receive data. Digital audio transferred over a single RCA coaxial
cable is in the S/PDIF format (Sony, Philips, Digital Interface Format), combining digital audio with
multiple clocks on a single wire cable.
Using a high quality RCA cable optimized for data transmission, connect the DMP RCA output
labeled Coax Front (Stereo) to your DAC’s RCA input.
MULTI CHANNEL OUTPUTS
Though DMP is primarily a two channel universal disc player, it is capable of playing multi channel
discs and delivering the highest quality digital audio to multiple DACS.
Many SACD as well as DVD-A and BluRay discs contain multi channel audio. DMP can deliver up
to six channels of digital audio through its I2S and RCA/coax outputs.
Using DMP’s I2S connections, DMP will deliver six channels of DSD or high resolution PCM to
three compatible DACs. If you choose PS Audio DACs, DMP will recognize them and assign
master control duties to the DAC connected to the Front/Stereo I2S connector. This permits
the user to control all three DACs through one remote control for a true high end multi channel
surround experience.
Connecting non-PS Audio DACs through compatible I2S (or coax) connections will deliver high
resolution PCM but not the locked DSD layer. The master slave relationship will also be unavailable
to non-PS Audio DACs
