Adjusting the sound

The player has various settings for adjusting the sound. You can adjust the sound with the following options.

  • “Sound adjustment” app.
  • The sound adjustment screens in “Music player”.

The following are instructions for using “Sound adjustment” app.

  1. On the Home screen, tap [Sound adjustment].
  2. Flick the screen to the left or right to select the sound adjustment.

You can set the following sound adjustment.

  • Direct Source
    This setting outputs the file’s original sound quality directly without applying any sound effects.
    Turn on this function to listen to music without processing the audio signals. This will be effective when you enjoy High-Resolution Audio content. On one of the sound adjustment screens, tap the [DIRECT] switch to turn this function on or off.
