3. Smart Volume
The Smart Volume feature automatically balances volume levels across different channels or content sources, preventing sudden loud or quiet changes. Activate or adjust this setting through the system's audio menu.

5. My Karaoke
Enjoy karaoke by connecting a microphone (not included) to the system. The voice cancellation technology can remove the lead vocals from most audio tracks, allowing you to sing along. Adjust microphone volume and echo effects through the system's menu.

Wipe the exterior surfaces of the main unit and speakers with a soft, dry cloth. Do not use liquid cleaners, abrasive pads, or chemical solvents, as these can damage the finish. Ensure the unit is unplugged before cleaning.
