Use the power amplifier board as far away as possible from the WiFi signal (router). 2. The recommended power supply voltage is DC 5-24V, if it exceeds 26V, the chip will burn. 3. The power supply current is recommended to be above 2A. 4. The speaker cable should not be too long, and ensure that it is suitable within 1 meter. 5. Pay attention to static electricity protection. Before touching the power amplifier board, you must first release the static electricity on your hands to avoid static electricity from breaking down the chip. Bluetooth-compatible chips are more sensitive to static electricity. 6. It is recommended to adapt the speaker with a rated power of 40W and above to avoid the speaker from heating and burning.
