1. When using the microphone, if the microphone is too close to the speaker or facing the speaker, and the volume of the amplifier is turned on, it is easy to generate high frequency sound feedback and cause whistling, which causes the tweeter to burn out. After the middle and high sounds pass through the frequency divider most of the signals are sent from the tweeter. This high-energy signal passes through the very fine tweeter of the coil, generating a large instantaneous current, causing an extremely high temperature, blowing the voice coil, and the tweeter is making a loud bang. After screaming, it broke down. The correct way is to not use the microphone and the speaker unit when you use the microphone. The volume of the amplifier should be increased from small to large. Don't drive to the maximum.
2. If the volume is too loud, it will damage the speaker. It is more likely that the power of the amplifier is insufficient and the sound is hard to open. The output of the amplifier is not a normal sine wave, but a signal with other clutter components, thus burning the speaker. .
3. If the amplifier has a DC output, it will burn the woofer, and even a very small number of tweeters will burn out. Because there is no capacitor isolated DC on the bass (or other) speaker line, a DC output is like turning the DC into the speaker, and the splitter coil is burnt together. Therefore, when purchasing the power amplifier, be sure to first use the multimeter current file to measure whether the output of the front and rear stages has DC output. If the front stage has DC output, it is possible to pass the rear stage and then amplify the output to DC.
