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，下面就來講講對舞臺燈光音響的檢測問題吧。
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 accidents. Let's talk about the detection of stage lighting and audio.
Inspection sequence for electrified shell of Shandong stage lighting equipment
設備外殼帶電檢查的順序是要檢查供電線路是否出現損壞的情況，其次是線路相位是否正確，其次還要了解設備接地和電壓是否正確。
The order of live inspection of equipment shell is to check whether the power supply line is damaged, whether the line phase is correct, and whether the equipment grounding and voltage are correct.
音響設備中無線話筒的聲音不穩定
Unstable sound of wireless microphone in professional audio equipment
音響設備中無線話筒的聲響不穩定假如無線話筒不穩定的狀況，首要就要查看聲響不穩定的原因在哪里，是因為體系內有高頻攪擾源導致的，仍是天線銜接錯誤、接收機微調、話筒電池電量等銜接設備呈現問題導致的。
The sound of wireless microphones in professional audio equipment is unstable. If the wireless microphones are unstable, we should first check the causes of the sound instability. It is caused by the high-frequency disturbance source in the system, or the antenna connection error, receiver fine adjustment, microphone battery power and other connection equipment problems.
音視頻系統中對視頻圖象的檢查
Inspection of video image in audio and video system
假如在音響設備中呈現視頻圖象不正常的狀況，首要就需求查看節目制式是不是在正確的規模，設備外殼有沒有帶電的狀況，其次還要查看信號屏蔽是不是容易遭到高電平攪擾，要查看投影管是否在正常的規模內，液晶投影的燈泡的性能有沒有呈現問題。
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 scale and whether the equipment shell is electrified. Secondly, it is also necessary to check whether the signal shield is easily disturbed by high-level interference. It is necessary to check whether the projection tube is in the normal scale and whether the performance of the liquid crystal projection bulb is present.
舞臺音響系統現場安裝需要注意的點
Points needing attention for on-site installation of stage audio system
1.演講者的布置應根據觀眾區的具體空間進行設計(集中或分散
1. The layout of speakers shall be designed according to the specific space of the audience area (centralized or decentralized
2.主控制臺的位置：盡量將其設置在舞臺前面的一側，并能聽到清晰范圍的廣播信號
2. Location of the main console: try to set it on the side in front of the stage and hear the broadcast signal in a clear range
3.確定電源時，注意避免與照明電源共用
3. When determining the power supply, pay attention to avoid sharing with the lighting power supply
4.線路分布注意弱電信號線和強電信號線。
4. Pay attention to weak current signal line and strong current signal line for line distribution.
此外還有一些細節上的問題需要及時進行排查，如果確認無誤后就能保證舞臺演出的順利進行，音響設備在檢查時需要仔細進行多次檢查，對于音量之類的小問題可以通過及時地調解進行操作，但是如果存在一些設備自身的問題就需要及時更換。更多相關問題就來我們網站

In addition, there are some detailed problems that need to be investigated in a timely manner. If they are confirmed to be correct, the smooth progress of the stage performance can be guaranteed. The audio equipment needs to be carefully checked many times during inspection. Small problems such as volume can be handled through timely mediation. However, if there are problems with the equipment itself, it needs to be replaced in a timely manner. Come to our website for more related questions http://www.zkvd.cn Consult.
