11. How to use the MQA function of BTR7?
When working as a USB DAC under 2.0 mode, the BTR7 supports MQA Renderer, which will show "MQA" on the display. It requires working with music applications that support MQA Core Decoder.
When using the Tidal app, please turn off the loudness normalization option and switch the quality to MQA in setting menu first.
