    Adaptive Sound for your content

    Adaptive Sound Control is LG's sound analyzing technology. It actively identifies what's playing and automatically adjusts sound settings to create the ideal audio experience to match the content you're watching.

    Auto Sound Engine, sound balance at any volume

    LG Auto Sound Engine optimizes your sound at any volume level and maintains precise frequencies at all times. This provides the appropriate sound balance regardless of the volume.

    Auto Music Play, music that follows you

    Sound starts the moment you enter the room. With Auto Music Play activated, the sound bar can automatically take over the playback of the audio from a connected device the moment it senses the device is nearby.

    Control with your TV Remote

    Control your Sound bar's basic functions with the remote you currently use the most, your TV remote.

    Feel free to connect to the device you wish with HDMI, Optical, Portable In and Bluetooth connectivity options.
