SPDIF SOURCE OPERATION

The SPDIF inputs include COAXIAL 1, COAXIAL 2, OPTICAL, and AES/EBU.

Select the desired input by pressing COAXIAL 1 or 2, AES/EBU, or OPTICAL button on the IR remote or control App.

If no source is connected to the selected input, it will say so.

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 to the specifications section of this manual for

more information.

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.

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:

SPDIF Digital

Output

Full Decoder

None

Core Decoder

MQA Core file

(up to 24/96)

Authenticating Decoder

Full MQA file

(up to 24/384)
