Bluetooth 5.0 Amplifier Board FAQs:

  1. Choosing a Power Supply: Opt for 18V19V24V with 3A or above for optimal performance. Lower voltage supplies can be used but may compromise sound quality.
  2. Selecting a Speaker: Commonly used 8-ohm speakers are ideal. Ensure the power supply matches the speaker’s capacity to prevent burnout.
  3. Bluetooth Connectivity: Simply search for “BT-WUZHI” on your device and connect. It auto-connects on subsequent uses.
  4. Sound Distortion: If the sound gets muddy at high volumes, consider a power supply with a higher voltage.
  5. Sound Interruptions: This could be due to an insufficient power supply or overheating. Ensure adequate power and cooling.
