Maintenance

To ensure the longevity and optimal performance of your ACS340 speakers, follow these maintenance guidelines:

  • Test with another audio source or device to rule out computer-related issues.
• Distorted Sound:
  • Reduce the volume on both the speakers and your computer.
  • Adjust the Bass and Treble knobs to see if the distortion improves.
