Is the volume different for each channel?



When there is difference in volume among channels though you didn’t turn the volume up/down, check if  “Auto Volume” is On.

 If you are using set-top box, Auto Volume and Smart Sound Mode features are not provided.



  How to fix

  1. Set the Auto Volume ‘On’.
  2. Set the Clear Voice and Smart Sound Mode ‘Off’.

- Auto Volume feature adjusts the volume appropriate for each channel automatically so that the volume is consistently set.

- Clear Voice feature is one that makes the voice of characters clear.

※ If the sound other than voice, such as background music, is not clear, set the Clear Voice ‘Off’.


If you are using Smart Sound Mode, the sound optimized for each content is automatically set and the sound quality may change, which will lead to difference in volume among channels.

※ This feature is provided for some models.
