舞台灯光音响设备正常与否，直接影响着演出效果，所以无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维修，避免意外情况的出现，所以说舞台灯光音响设备演出前建议要检查。
Whether the stage lighting and sound equipment is normal or not directly affects the performance effect, so both professional sound equipment and stage lighting equipment need to be well maintained. The lines and equipment that have problems should be repaired in time to avoid accidents. Therefore, it is recommended to check the stage lighting and sound equipment before the performance.
1、舞台音响灯光设备外壳带电现象检查
1. Inspection of electrified shell of stage audio and lighting equipment
设备外壳带电检查是要检查供电线路是否出现损坏情况，其次是线路相位是否正确，检查设备接地和电压是否正确。
The electrified inspection of the equipment shell is to check whether the power supply line is damaged first, and then whether the line phase is correct, and whether the equipment grounding and voltage are correct.
2、舞台音响系统中音量不足的检查
2. Inspection of insufficient volume in stage sound system
一般情况下如果音响设备中出现音量不足的情况，就要及时检查功放和音箱的线路电平设置是否正确，还要了解音箱线连接是否牢固，以及功放与音箱的相位是否一致，均衡器衰减幅度是否在正常的范围，压限器的起控电平是否恰当。
Generally, if there is insufficient volume in the audio equipment, it is necessary to timely check whether the line level setting of the power amplifier and the speaker is correct, and also to know whether the speaker line is firmly connected, whether the phase of the power amplifier and the speaker is consistent, whether the attenuation amplitude of the equalizer is in a normal range, and whether the starting control level of the voltage limiter is appropriate.
3、舞台音响产生干扰噪声的检查
3. Inspection of interference noise produced by stage sound
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，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。一般情况下出现音箱系统有噪声的情况，大都是由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时候，就容易出现噪声干扰的情况。
If there is noise in professional audio equipment, first of all, 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. Generally, the noise in the speaker system is mostly caused by the unreasonable signal transmission. Therefore, when there is a problem with the shielding of the signal line or the grounding of the signal is incorrect, noise interference is easy to occur.
4、舞台灯光失控的检查
4. Inspection of stage lighting out of control
灯光失控就要检查控制器的程序有没有问题，灯具的地址编码有没有出现问题，控制线的接法是不是正确，还有需要检查控制线的屏蔽有没有受到不良干扰，灯具的限位调整是否恰当等。
If the light is out of control, it is necessary to check whether there is a problem with the program of the controller, whether there is a problem with the address code of the lamp, whether the connection method of the control line is correct, and whether the shielding of the control line is subject to adverse interference, whether the limit adjustment of the lamp is appropriate, etc.
5、舞台电脑灯灯泡损坏检查
5. Stage computer light bulb damage inspection
在
山东舞台灯光音响中容易出现的就是灯泡易坏的情况，所以当出现问题的时候，需要检查安装的灯泡是否牢靠，有没有沾染尘土和水气，还有就是要检查灯泡的散热是不是在正常范围内，电压是否在正常的范围内，有没有使用电源开关过于频繁的情况。
In Shandong stage lighting and sound, the bulb is easy to break, so when there is a problem, first of all, it is necessary to check whether the installed bulb is secure, whether it is contaminated with dust and moisture, and whether the heat dissipation of the bulb is within the normal range, whether the voltage is within the normal range, and whether the power switch is used too frequently.
