3. Setup Instructions

Unpacking: Carefully remove the subwoofer from its packaging. Retain all packaging materials for future transport or service.
Placement: Position the subwoofer on a stable, flat surface. For optimal bass performance, consider placing it in a corner or near a wall, but experiment with different locations to find the best sound for your room. Ensure adequate ventilation around the unit.
Connection:
- Identify the subwoofer output port on your compatible LG audio system or receiver.
- Connect the appropriate audio cable (e.g., RCA subwoofer cable) from your audio system's subwoofer output to the input on the LG TCG35391007 Subwoofer Speaker.
- Ensure all connections are secure to prevent signal loss or interference.
Power Connection: Plug the power cord into the subwoofer's power input, then into a standard electrical outlet.
Initial Power On: Turn on your audio system and then the subwoofer. Refer to your main audio system's manual for specific settings related to subwoofer integration and level adjustment.

Note: This subwoofer is designed as an OEM replacement or accessory. Compatibility with non-LG systems or specific LG models should be verified with your system's documentation or LG support.

4. Operating Instructions

Once properly connected and powered on, the LG TCG35391007 Subwoofer Speaker will automatically receive low-frequency audio signals from your connected audio system. Most adjustments, such as volume level and crossover frequency, are typically controlled through the main audio system or receiver.

Volume/Level: Adjust the subwoofer's output level to blend seamlessly with your main speakers. Avoid setting the level too high, which can result in boomy or distorted bass.
Crossover Frequency: If your audio system allows, set the crossover frequency to ensure the subwoofer handles frequencies below a certain point, while your main speakers handle higher frequencies. A common starting point is 80 Hz, but this may vary based on your main speakers' capabilities.
Phase Control: Some audio systems offer a phase control (0° or 180°). Experiment with this setting to achieve the most impactful and coherent bass response with your main speakers.

Always refer to your primary audio system's user manual for detailed instructions on configuring external subwoofers.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your subwoofer.

Cleaning: Use a soft, dry cloth to wipe the exterior surfaces of the subwoofer. Avoid using liquid cleaners, aerosols, or abrasive materials, as these can damage the finish or internal components.
Ventilation: Ensure that the subwoofer's vents (if any) and bass reflex ports are not obstructed to prevent overheating.
Cable Connections: Periodically check all cable connections to ensure they are secure and free from corrosion or damage.
Storage: If storing the subwoofer for an extended period, disconnect it from power, clean it, and store it in a cool, dry place, ideally in its original packaging.
