Recommended power supply voltage is DC 8-24V. If it exceeds 26V, the chip will burn out. <br/>2. When connected to a 4 Ω speaker, the power supply should not exceed 16V, and when connected to an 8 Ω speaker, the power supply should not exceed 24V. <br/>3. The recommended power supply current is 2A or above. <br/>4. The positive and negative poles of the power supply cannot be connected in reverse, as the chip may burn out when connected in reverse; This module is only suitable for single power supply and cannot be connected to negative power supply. <br/>5. Ensure that the input audio signal is between 0.5V and 1.5V <br/>6. The horn cable should not be too long, ensuring it is suitable within 1 meter <br/>7. Pay attention to electrostatic protection. Before touching the power amplifier board, release the static electricity on your hands to avoid the static electricity from breaking down the power amplifier chip. Digital power amplifiers are sensitive to static electricity. <br/>8. It is recommended to use speakers with a rated power of 30W or above to avoid overheating and burning of the speakers</p><p>Troubleshooting: <br/>1. After powering on, the horn beeped and there was no response <br/>1) Check if the impedance of the speaker is too small and the power supply voltage is too high, causing the chip to enter DC protection due to the instantaneous high current; Attempt to reduce the power supply voltage and restart. <br/>2) Check if the power supply is too low to operate the speaker, and try replacing it with a high-power power supply. Generally, a 2A power adapter is not a problem. <br/>2. Playing music has a &quot;sizzling&quot; noise <br/>1) Replace the audio source to see if it is the inherent noise of the audio source itself. <br/>2) Is it a problem with the amplifier itself to ground the input terminal of the amplifier <br/>3) Is using shielded audio cables introducing noise due to cable quality issues <br/>4) Replace the speaker, is it a problem with the speaker itself <br/>5) Replacing the power supply, is the noise caused by unstable power supply <br/>3. The speaker heats up and emits smoke during playback <br/>1) The power of the horn is too low. Replace the high-power horn or reduce the signal input<br/><br/></p></div></div><p><br/></p>
