SPDIF SOURCE OPERATION
SPDIF INPUTS
The SPDIF inputs include
COAXIAL 1, COAXIAL 2, OPTICAL, and AES/EBU.
1.
Select the desired input by pressing
COAXIAL 1 or 2, AES/EBU or OPTICAL
button on the IR remote or control App.
2.
If no source is connected to the selected input, it will say so.
3.
Initiate playback of the corresponding SPDIF source.
NOTE:
SDPIF inputs accept DSD and PCM signals (see DSD Section below for more on this topic). PCM inputs and output
rates over coaxial and AES/EBU can be up to 24-bit / 768kHz. PCM input and output rates over optical can be up to 24-bit /
1924kHz. They can also accept an MQA signal but will not decode MQA. However, it will playback at better than CD quality
in native FLAC 16 bit/44.1kHz/48kHz/88.2kHz/96kHz format. Please refer the specifications section of this manual for more
information.
SPDIF OUTPUTS
The SPDIF outputs include one each of
COAXIAL and OPTICAL.
When playing DSD or PCM files of 16
–
24 Bit, 44.1 kHz - 768 kHz, digital output from SPDIF will match the source.
SPDIF OUTPUTS WHILE PLAYING MQA FILES
When playing MQA files, the SPDIF digital outputs will function differently based on the type of MQA Decoder that is
selected in the DMS MQA Decoder system settings. Selecting anything other than “Full Decoder” is only
useful if needing to
pass through the MQA signal to an additional outboard MQA Certified DAC. The type of MQA Decoder selected will affect
the MQA playback sound quality of the DMS analog outputs. Please see the MQA Operation section of the manual to learn
how each MQA decoder affects the analog sound quality of the DMS.
The selected decoder will affect the SPDIF digital outputs as follows:
Full Decoder
Core Decoder
Authenticating Decoder
SPDIF Digital
Output
None
MQA Core file
(up to 24/96)
Full MQA file
(up to 24/384)
