11. How to use the MQA function of BTR15?

When working as a USB DAC under 2.0 mode, the BTR15 supports MQA Full Decoder, which will show "MQA" on the display. It requires working with music applications that support MQA Full Decoder.

When using the Tidal app, please turn off the loudness normalization option and switch the quality to MQA in setting menu first.

Connect the BTR15 to the mobile phone via USB and play MQA file in Tidal. "MQA" displayed on the BTR15 means the MQA is working.
