An important reason why the loudspeaker burns the treble is that the power of the power amplifier is too small, not too large. The signal sent by the power amplifier is a clipping signal, which causes damage to the loudspeaker. Therefore, when equipping the speaker, we must establish a correct understanding and use the plan of "big horse-drawn trolley" to avoid the power amplifier sending a clipping signal and damaging the high-range and mid-range speaker units.

In the planning of the speaker system, the power amplifier and the speaker planning power plan to match the above criteria, the actual operation of each link of the equipment to use reasonably, in order to not only protect the equipment, but also to make the speaker system to achieve the best effect. For volume adjustment, many users put the attenuator of the post-amp amplifier at -6dB, -10dB, that is, 70 percent to -80 percent of the volume knob, and even the general direction, and rely on increasing the input of the mixer to achieve the appropriate volume.

Thinking that the power amplifier has a margin, the speaker will be safe, but in fact, this is also at fault. The attenuation knob of the power amplifier attenuates the input signal, if the input of the power amplifier is attenuated by 6dB, it means that to adhere to the equal volume, it is necessary to output 6dB more than the mixer or preamp, the voltage should be 1 times higher, and the upper dynamic margin of the input, commonly known as "overhead space", will be cut in half.

At this time, if there is a sudden large signal, the mixer output will be overloaded by 6dB earlier, showing a clipping waveform. Although the amplifier is not overloaded, the input is a clipped waveform, and the treble weight is too heavy, not only the treble is distorted, but the tweeter may also burn out.
