If the TV and Sound Bar are not connected by an HDMI cable, the sound output from the TV will not change over to Sound Bar automatically. Therefore, sound comes out of the Sound Bar and the TV speakers at the same time.
The method for turning off the sound of the TV speakers differs depending on the connection environment. See the following for details.
- When connecting with an optical digital audio cable: Set the TV volume lower as much as possible while viewing.
- When connecting with an analog audio cable: Set the TV audio output to come out of the external speakers.
NOTE: For details, refer to the instruction manuals of the TV.
