Check if the POWER indicator is on. If it is not lit, press the POWER button to turn it on. After pressing the power button, the indicator light still does not light. At this time, you can find a laptop power supply to test to determine whether it is a machine fault or a power failure. 2. If the indicator light is on, check if the VOL knob is in the minimum state, such as clockwise rotation in the minimum state. 3. If both of the above are normal, check if the device that inputs the sound source is paused, muted, or the volume is at its minimum. Q: Why is the sound broken? A: When the power amplifier exceeds the normal output power, there will be a large distortion. At this time, you can adjust the volume of the front stage or the volume of the power amplifier to be normal. Q: Why does the speaker have a large current sound? A: If you are not using the original standard power supply, please replace the power supply before testing. Many power supplies in the market have a large interference coefficient, which will cause a large current sound. Q: Why doesn't my amp work after working for a while, and then work normally after disconnecting for a while? A: Usually this is the overheat protection of the amplifier. The output power may have exceeded the design power. At this point, you can lower the volume and try again. Note: 1. Please do not open the shell without permission. Improper operation may cause the danger of electric shock. 2. Please use the power supply of the regular manufacturer, otherwise it will damage the machine. 3. Please do not use the machine in a high temperature and humidity environment. Package included: 1pcs TPA3116D2 Subwoofer+ 1pcs Power Adapter DC19V 4.74A
