Frequently Asked Questions:

• Q1: How to choose a power supply adapter?
  A: Ensure a higher voltage and current power supply for better output. For 12V 1A, it is advisable to use speakers not exceeding 3-4 inches. For 19V 5A, up to 8-10 inches is suitable. Avoid low power adapters to prevent distortion.
• Q2: How to choose a speaker?
  A: Use speakers within 4Ω-8Ω. For low-power speakers (10W-30W), keep the adapter below 15V. For 50W-100W speakers, 12V-24V power is recommended. Higher voltage enables greater sound output.
• Q3: How to choose an audio input mode?
  A: AUX has higher priority than Bluetooth. Switch USB Audio mode via the APP.
• Q4: Why does audio distort or stop at higher volumes?
  A: This may be due to low input power. Increase the voltage or switch to a higher-rated power adapter.
