What maintenance does the YST-SW45 subwoofer require to keep it in good condition?

Regularly clean the exterior of the YST-SW45 subwoofer with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or water. Periodically check the cables for any signs of wear or damage, and ensure all connections are secure. Store the subwoofer in a cool, dry place to prevent moisture damage.

How do I troubleshoot distortion issues with the YST-SW45 subwoofer?

If you experience distortion from the YST-SW45 subwoofer, try reducing the volume level on both the subwoofer and the AV receiver. Ensure the subwoofer is not being overdriven with too much power.

What is the best way to calibrate the YST-SW45 subwoofer with my existing speaker system?

To calibrate the YST-SW45 subwoofer, use an SPL (sound pressure level) meter or a smartphone app to measure the sound levels. Adjust the subwoofer volume and crossover frequency to match the output of your main speakers. Many AV receivers have an automatic calibration feature that can also aid in setting up your system accurately.

How do I know if my YST-SW45 subwoofer is set at the correct phase?

The phase setting on your YST-SW45 subwoofer can either be 0° or 180°. To determine the correct setting, play bass-heavy music or a test tone while switching between the two settings. Choose the setting that provides the strongest and most cohesive bass response. It may require some trial and error based on your room acoustics and speaker placement.

What should I do if my YST-SW45 subwoofer hums or buzzes?

A humming or buzzing sound from the YST-SW45 subwoofer may be caused by a ground loop. To resolve this, try connecting all audio equipment to the same power outlet using a power strip. Ensure all cables are properly shielded and in good condition. If the problem persists, consider using a ground loop isolator.
