山東舞臺燈光音響的正常與否直接的影響著演出的效果，所以不論是音響設備還是舞臺燈光設備都需要做好保養和維護工作，對出現問題的線路和設備應及時的維修，避免意外情況的出現。
Whether the lighting and sound of Shandong stage is normal or not directly affects the performance effect. Therefore, both professional audio equipment and stage lighting equipment need to be well maintained. The faulty lines and equipment should be repaired in time to avoid unexpected situations.
產生干擾噪聲的檢查方法
Inspection method for generating interference noise
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，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。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。
If there is noise in professional audio equipment, first check whether the dimming interference, audio and light power supply are disconnected, and then 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. In general, the noise in the speaker system is usually caused by unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal grounding is incorrect, noise interference is likely to occur.
燈光失控的檢查方法
Inspection method for light out of control
燈光失控就要檢查控制器的程序有沒有問題，燈具的地址編碼有沒有出現問題，控制線的接法是不是正確，還有需要檢查控制線的屏蔽有沒有受到不良干擾，燈具的限位調整是否恰當等。
If the light is out of control, it is necessary to check whether there is a problem with the controller program, whether there is a problem with the address code of the lamp, whether the connection of the control line is correct, whether the shielding of the control line is adversely affected, and whether the limit adjustment of the lamp is appropriate.
電腦燈燈泡損壞檢查
Inspection for damage of computer lamp bulb
在舞臺音響燈光中容易出現的就是燈泡易壞的情況，所以出現問題，就要檢查安裝的燈泡否牢靠，有沒有沾染塵土和水氣，還有就是要檢查燈泡的散熱是不是在正常范圍內，好需要檢查的是電壓是否在正常的范圍內，有沒有使用電源開關過于頻繁的情況。
In the stage sound and lighting, it is easy for the bulb to break. Therefore, if there is a problem, it is necessary to check whether the installed bulb is reliable, whether it is contaminated with dust and moisture, and whether the heat dissipation of the bulb is within the normal range. What needs to be checked is whether the voltage is within the normal range, and whether the power switch is used too frequently.
音視頻系統中對視頻圖象的檢查
Inspection of video image in audio and video system
如果在音響設備中出現視頻圖象不正常的情況，就需要檢查節目制式是不是在正確的范圍，設備外殼有沒有帶電的情況，其次還要檢查信號屏蔽是不是容易受到高電平干擾，好要檢查投影管是否在正常的范圍內，液晶投影的燈泡的性能有沒有出現問題。
If the video image is abnormal in the professional audio equipment, first of all, it is necessary to check whether the program format is in the correct range and whether the equipment shell is charged. Secondly, it is also necessary to check whether the signal shield is susceptible to high-level interference. It is necessary to check whether the projection tube is in the normal range and whether the performance of the liquid crystal projection bulb is defective.
音響設備中無線話筒的聲音不穩定
Unstable sound of wireless microphone in professional audio equipment
如果無線話筒不穩定的情況，就要檢查聲音不穩定的原因在哪里，是由于系統內有高頻干擾源導致的，還是天線連接錯誤、接收機微調、話筒電池電量等連接設備出現問題導致的。
If the wireless microphone is unstable, first of all, check the cause of the sound instability. It is caused by the high-frequency interference source in the system, or the antenna connection error, receiver fine adjustment, microphone battery power and other connection equipment problems.
The above is about the stage lighting and sound detection knowledge. I hope it will help you. If you want to know more, please follow our website http://www.zkvd.cn We will bring you more practical technical support.
