對于舞臺常使用的音響而言，一般他可能會出現線路故障、音響嘯叫、電流平衡、信號分配、壓限器異常等問題。下面，
山東舞臺音響廠家來講舞臺音響的嘯叫問題怎么解決這一問題。
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.
應該取推子的后置信號，避免效果不受控引起話筒嘯叫，返回有條件占用一路通道，這樣調試更方便。音響設備中如果有噪聲，就要檢查調光干擾，音響和燈光電源是否出現斷開的情況。
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.
其次就要檢查燈光電源和控制線路是否離音頻信號線太近，有沒有出現硅箱離音頻設備太近的情況。
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.
一般情況下出現音箱系統有噪聲的情況，通常都是由于信號的傳輸不合理的情況所導致的，所以當信號線的屏蔽出現問題，或者信號的接地不正確的情況，就容易出現噪聲干擾的情況。
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.
如果在音響設備中出現共振和聲反饋的情況，要檢查房間頻響是否有峰點，還有就是要檢查房間結構和裝飾是否合理，建議是還要檢查分頻點和低音增益是否合理，房間混響時間是否出現過長的情況。
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.
如果舞臺音響出了問題會直接導致演出無法順利進行。因此，我們須要知道舞臺音響可能會遇到一些什么樣的問題，并及時采取有效的手段來防止或解決這些問題的出現。
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.
事實證明，要想避免舞臺音響出現問題，就要懂得如何使用和保養音響，使其不受到傷害。也只有這樣，才能夠真體驗到音響發出的美妙的聲音。關注我們
