We often encounter a lot of questions about the sound on the stage. For example, one day the speaker suddenly can't be clicked, there is no sound at all, and for example, the sound of the sound becomes turbid or the treble does not go up. Why is this happening? In addition to being related to the service life, how to use it everyday is also a matter of learning.
Here is a summary for everyone:
First, pay attention to the wiring problem of the speaker. When listening, check whether the wiring is correct and the potentiometer position is too large. Most of the current speakers are 220 volt power supply design, but some products that are imported back are not excluded. Most of these speakers use 110 volt power supply. Due to the voltage difference, one speaker may be scrapped.
Second, stacking equipment. Many people will place speakers, tuners, digital-to-analog converters and other machines on top of each other, which will cause mutual interference, especially if the radium camera and the power amplifier interfere heavily, which will make the tone harder and more depressed. The correct approach is to place the equipment on an audio frame designed by the factory.
Third, the speaker cleaning problem. When cleaning the speaker, pay attention to cleaning the terminal of the speaker cable. Because the speaker cable is oxidized more or less after using the speaker for a period of time, this oxide film will greatly affect the contact state, thus degrading the sound quality. The user applies a cleaning agent to clean the contact points in order to maintain an optimal connection.
Fourth, the wiring is not handled properly. Do not tie the power cable to the signal cable when handling the wiring. Because the AC power will affect the signal; the signal cable or speaker cable can not be tied, otherwise it will affect the tone.
Fifth, avoid the microphone should not point to the speaker. When the sound of the speaker enters the microphone, it will form an acoustic feedback and produce a howling. If the consequences are serious, the high-pitched part will even be burned. Secondly, the speakers should also be kept away from strong magnetic fields. Do not approach sensitive magnetized items such as monitors and mobile phones. The distance between the two speakers should not be too close to avoid noise.
