Module protection mechanism:

Reverse power protection

Short circuit protection

Self-recovery overheat protection

Note: In order to improve the performance of the module, it is recommended that the power amplifier chip plus a heat sink be used in application scenarios that exceed 20W*2.

Precautions for use:

1. The recommended power supply voltage is DC 8~24V, if it exceeds 26V, the chip will burn, and if it is lower than 8V, there will be noise.

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, need to add heat sink

5. Ensure that the input sound source signal is 0.5V~1.5V

6. The speaker wire should not be too long, and it should be suitable within 1 meter

7. Pay attention to electrostatic protection. Before touching the power amplifier board, you must first discharge the static electricity on your hand to avoid the static electricity from puncturing the power amplifier chip. The digital power amplifier is more sensitive to static electricity.
