Precautions for use
1. Recommended power supply voltage DC 8~24V, more than 26V, the chip will burn out.
2. The power supply does not exceed 16V when connected to a 4Ω speaker, and the power supply does not exceed 24V when connected to an 8Ω speaker.
3. The supply current is recommended to be 2A or more.
4. The positive and negative poles of the power supply can not be reversed, and the reverse chip is burned.
This module is only suitable for single-supply power supply and cannot be connected to a negative power supply.
5. Ensure that the input source signal is between 0.5V and 1.5V.
6. The speaker cable should not be too long, and it should be suitable within 1 meter.
7. Pay attention to static electricity protection.
Before touching the power amplifier board, first discharge the static electricity on the hand to avoid static electricity from penetrating the power amplifier chip.
The digital power amplifier is sensitive to static electricity.
8. It is recommended to use the rated power of the speaker at 30W or above to avoid the burning of the speaker.
