How to turn off only the sound of the TV speakers when using the Sound Bar.

If the TV and Sound Bar are not connected by an HDMI cable, the sound output from the TV will not automatically change over to the Sound Bar.
Therefore, the Sound Bar and the TV speakers will emit sound at the same time.

The method for turning off the sound of the TV speakers differs, depending on the connection environment:

• When an Optical Cable is connecting the TV and the Soundbar, simply change the Audio Settings to emit the sound via the Optical Output. This means that the sound will come from the Soundbar only, regardless of the TV volume level.
  
• When connecting with an analogue audio cable: Set the TV audio output to come out of the external speakers.

NOTE: For extra details, refer to the instruction manuals of the TV.
