How to play MQA

This machine’s USB, optical, and coaxial support for MQA decoding!
This machine’s MQA playback does not require the use of special playback software, such as foobar2000, Audirvanaplus as long as the support for ASIO or WASAPI audio output can be, and in the playback of MQA audio, it is best to turn the computer’s volume to the maximum, to make the computer’s audio output is the best state.
When playing MQA ﬁles, the sample rate shown on the display is the original sample rate of the audio.

Notes on playing MQA-CD

Please make sure that what is being played is a genuine MQA-CD.
Verify that the optical or coaxial signal output of the CD player is an unprocessed source code.

Connect to an ARC-compatible TV through HDMI

Connect an ARC-compatible TV to this product using a commercially available HDMI cable.

TIPS:

Connect to an HDMI IN port labeled “ARC” or “eARC/ARC” on the TV. This type of label indicates that the port supports “only ARC” or “both eARC and ARC”. If connected to a port that does not support ARC, the ARC input function of this product cannot be used.
For this type of connection, please use an HDMI cable (19-pin) with the HDMI logo indicating compatibility with ARC. You may need to change the settings on your TV. Please refer to the user manual for the TV.
This product cannot output videos. (Meaning that it’s HDMI ARC, not HDMI. Supports digital signal input, not video input.)
If you play audio from a TV that does not support ARC, please connect the TV’s audio output port to the audio IN port (OPTICAL, COAXIAL, or AUX) of this product.
