• Short circuit protection
• Self-recovery overheating protection

Notes on use:

• The recommended power supply voltage is DC 8~24V. If it exceeds 26V, the chip will burn out, and if it is lower than 8V, there will be noise.
• When connected to a 4Ω speaker, the power supply does not exceed 12V, and when connected to an 8Ω speaker, the power supply does not exceed 24V.
• The power supply current is recommended to be above 2A.
• working power of the module exceeds 20W*2, and a heat sink needs to be added
• Ensure that the input audio signal is within 0.5V~1.5V The speaker cable should not be too long, and it should be within 1 meter.
• 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 from breaking down the power amplifier chip. Digital power amplifiers are more sensitive to static electricity.
• It is recommended to use speakers with a rated power of 30W and above to avoid heating and burning the speakers
