The choice of music player app, the setting of music player and the setting of computer/phone will all have an impact on the sampling rate.

The sampling rate displayed by this unit is the sampling rate of the input signal, and it will not change the sampling rate by itself.

If the music player can be set to exclusive mode, the audio signal will not be resampled by the computer/phone, so the sampling rate of the output signal is the sampling rate of the original file, and the sampling rate displayed by this unit is also the sampling rate of the original file.

Because some players can't be set to exclusive mode, the audio signal will be resampled by the computer/phone and then output. So this unit will always display the sampling rate set by the computer/phone.

We recommend using Audirvana player on MAC OS and Foobar on windows OS.

Please check if DAC mode was set in [Setup Menu - Advance - DAC]. In DAC mode, the volume is not adjustable and is the maximum value, while in PRE mode the volume can be adjusted. Set it to PRE mode if you need to adjust the volume.
