不论是音响设备还是舞台灯光设备都需要做好保养和维护工作，对出现问题的线路和设备应及时的维修避免意外情况的出现，下面就来讲讲对舞台灯光音响的检测问题吧。
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
设备外壳带电检查的顺序是要检查供电线路是否出现损坏的情况，其次是线路相位是否正确，其次还要了解设备接地和电压是否正确。
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.
音响设备中无线话筒的声音不稳定
Unstable sound of wireless microphone in professional audio equipment
音响设备中无线话筒的声响不稳定假如无线话筒不稳定的状况，首要就要查看声响不稳定的原因在哪里，是因为体系内有高频搅扰源导致的，仍是天线衔接错误、接收机微调、话筒电池电量等衔接设备呈现问题导致的。
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.
音视频系统中对视频图象的检查
Inspection of video image in audio and video system
假如在音响设备中呈现视频图象不正常的状况，首要就需求查看节目制式是不是在正确的规模，设备外壳有没有带电的状况，其次还要查看信号屏蔽是不是容易遭到高电平搅扰，要查看投影管是否在正常的规模内，液晶投影的灯泡的性能有没有呈现问题。
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.
舞台音响系统现场安装需要注意的点
Points needing attention for on-site installation of stage audio system
1.演讲者的布置应根据观众区的具体空间进行设计(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.主控制台的位置：尽量将其设置在舞台前面的一侧，并能听到清晰范围的广播信号
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.确定电源时，注意避免与照明电源共用
3. When determining the power supply, pay attention to avoid sharing with the lighting power supply
4.线路分布注意弱电信号线和强电信号线。
4. Pay attention to weak current signal line and strong current signal line for line distribution.
此外还有一些细节上的问题需要及时进行排查，如果确认无误后就能保证舞台演出的顺利进行，音响设备在检查时需要仔细进行多次检查，对于音量之类的小问题可以通过及时地调解进行操作，但是如果存在一些设备自身的问题就需要及时更换。更多相关问题就来我们网站
