对于舞台常使用的音响而言，一般他可能会出现线路故障、音响啸叫、电流平衡、信号分配、压限器异常等问题。下面，
山东舞台音响厂家来讲舞台音响的啸叫问题怎么解决这一问题。
For the audio often used on the stage, there may be problems such as circuit failure, audio squeal, current balance, signal distribution, and abnormal voltage limiter. Next, Shandong stage audio manufacturers will talk about how to solve the problem of stage audio squealing.
应该取推子的后置信号，避免效果不受控引起话筒啸叫，返回有条件占用一路通道，这样调试更方便。音响设备中如果有噪声，就要检查调光干扰，音响和灯光电源是否出现断开的情况。
The rear signal of the pusher should be taken to avoid the microphone howling due to uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging. If there is noise in the audio equipment, first check the dimming interference and whether the audio and light power supplies are disconnected.
其次就要检查灯光电源和控制线路是否离音频信号线太近，有没有出现硅箱离音频设备太近的情况。
Next, check whether the light power supply and control line are too close to the audio signal line, and whether the silicon box is too close to the audio equipment.
一般情况下出现音箱系统有噪声的情况，通常都是由于信号的传输不合理的情况所导致的，所以当信号线的屏蔽出现问题，或者信号的接地不正确的情况，就容易出现噪声干扰的情况。
Generally, the noise of the speaker system is caused by the unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal grounding is incorrect, the noise interference is likely to occur.
如果在音响设备中出现共振和声反馈的情况，要检查房间频响是否有峰点，还有就是要检查房间结构和装饰是否合理，建议是还要检查分频点和低音增益是否合理，房间混响时间是否出现过长的情况。
If resonance and acoustic feedback occur in professional audio equipment, first check whether there is a peak in the room frequency response, and then check whether the room structure and decoration are reasonable. It is recommended that you also check whether the frequency dividing point and bass gain are reasonable, and whether the room reverberation time is too long.
如果舞台音响出了问题会直接导致演出无法顺利进行。因此，我们须要知道舞台音响可能会遇到一些什么样的问题，并及时采取有效的手段来防止或解决这些问题的出现。
If there is a problem with the stage sound, the performance will not go smoothly. Therefore, we need to know what problems stage acoustics may encounter, and take effective measures to prevent or solve these problems.
事实证明，要想避免舞台音响出现问题，就要懂得如何使用和保养音响，使其不受到伤害。也只有这样，才能够真体验到音响发出的美妙的声音。关注我们
