Technical Features & Troubleshooting
  • Bluetooth Connectivity: If the Bluetooth indicator light is not flashing regularly or stays on continuously, there may be an issue with the PAM8403 audio power amplifier board. Contact customer service for resolution.
  • Computer Connection Issues: If your phone connects but your laptop/desktop cannot, this may be due to outdated or missing Bluetooth drivers. Uninstall and reinstall the latest driver version.
  • Sound Distortion: Distorted, choppy, or breaking sound at high volume may indicate insufficient power supply or amplifier-speaker mismatch, which could damage components.
  • Background Noise: Some noise is normal during signal amplification, but excessive background noise may indicate power supply issues or board problems.
  • Quality Assurance: Contact customer service for troubleshooting, repair, or replacement options if you encounter any issues.
Important Notes
Due to different monitor and lighting conditions, the actual color of the item might be slightly different from the pictures. Please allow 1-2cm measuring deviation due to manual measurement.

This analog amplifier module works perfectly! The sound quality is crystal clear from 20Hz to 20KHz. The 3.5mm input interface is very convenient and the silver finish looks professional. Great value for money, highly recommended for audio enthusiasts!
