5. Operating Instructions
Powering On/Off
Use the Power Switch on the rear panel to turn the subwoofer on or off.
Volume Adjustment
Rotate the 'Volume Adjustment' knob on the rear panel to increase or decrease the subwoofer's output level. Start with a low volume and gradually increase it to your desired level.
Low-Pass Crossover Adjustment
The 'Low Pass Crossover' knob allows you to set the upper frequency limit for the subwoofer, typically between 40Hz and 180Hz. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A good starting point is usually around 80Hz, but this may vary depending on your main speakers' frequency response.
Phase Selection
The 'Phase' switch (0°/180°) helps ensure that the subwoofer's sound waves are in sync with your main speakers. Experiment with both settings to find the one that produces the most impactful and coherent bass response at your listening position.
6. Maintenance

To clean the subwoofer, first unplug it from the power outlet. Use a soft, dry, lint-free cloth to wipe down the cabinet. Do not use abrasive cleaners, waxes, or solvents, as these can damage the finish.
