Precautions for use:
1. The recommended power supply voltage is DC 8~24V. If it exceeds 26V, the chip will be burnt, and noise will occur if it is below 8V.
2. The power supply does not exceed 12V when connected to a 4Ω speaker, and does not exceed 24V when connected to an 8Ω speaker.
3. The power supply current is recommended to be above 2A.
4. The working power of the module exceeds 20W*2, and a heat sink is required.
5. Ensure that the input audio signal is within 0.5V~1.5V.
6. The speaker cable should not be too long, and it is better to keep it within 1 meter.
7. Pay attention to static electricity protection. Before touching the power amplifier board, you need to release the static electricity on your hands to avoid static electricity.
Chip breakdown, digital power amplifier is more sensitive to static electricity.
8. It is recommended to use the speaker with a rated power of 30W and above to avoid the speaker from heating and burning.
