Note:
1. The product is a finished board.
2. The power interface has built-in anti-reverse connection protection.
3. The output power depends on the power supply voltage and the speaker impedance. The recommended voltage for high-power occasions is 24V, and the current is more than 5A. Use a 4 ohm speaker for high power.
4. The judgment method of bottom noise: short circuit at the input end, connect to the speaker for listening. Normally, it should be very weak noise (generally not obvious about 50cm away from the speaker). Too loud means abnormal. If connecting computer or mobile phone, and the noise increases, which indicates that the noise comes from the signal source.
5. The current capacity of the 5V port for external power supply is limited, please use it with caution.
