舞台音响灯光的正常与否直接影响着演出的效果,所以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维修,避免意外情况的出现。如果现场出现
山东舞台灯光音响问题,应该这样处理:
Whether the stage audio and lighting are normal or not directly affects the performance effect, so both the audio equipment and the stage lighting equipment need to be well maintained. The faulty lines and equipment should be repaired in time to avoid accidents. If there is a problem with Shandong stage lighting and sound on the scene, it should be handled as follows:
1、舞台音响灯光设备外壳有带电现象的检查顺序。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,还要了解设备接地和电压是否正确。
1. Inspection sequence for electrification of stage audio and lighting equipment shell. The order of live inspection of equipment shell is to check whether the power supply line is damaged, and then to check whether the line phase is correct, and to know whether the equipment grounding and voltage are correct.
2、音响系统中音量不足的情况检查顺序。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,其次还要了解音箱线连接是否牢固,还有就是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。
2. Check the order of insufficient volume in the audio system. Generally, if there is insufficient volume in the audio equipment, it is necessary to check whether the line level setting of the power amplifier and the speaker is correct in time. Secondly, it is also necessary to know whether the speaker cable connection is firm, and whether the phase of the power amplifier and the speaker is consistent, whether the attenuation amplitude of the equalizer is within the normal range, and whether the threshold level of the limiter is appropriate.
3、怎么检查声场中发生共振和声反馈。如果在音响设备中出现共振和声反馈的情况,要检查房间频响是否有峰点,还有就是要检查房间结构和装饰是否合理,好还要检查分频点和低音增益是否合理,房间混响时间是否出现过长的情况。
3. How to check resonance and acoustic feedback in the sound field. If resonance and acoustic feedback occur in the audio equipment, first of all, check whether the room frequency response has peaks, and then check whether the room structure and decoration are reasonable, and also check whether the frequency division point and bass gain are reasonable, and whether the room reverberation time is too long.

4、产生干扰噪声的检查方法。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,通常都是由于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,就容易出现噪声干扰的情况。
4. Inspection method for generating interference noise. If there is noise in the audio equipment, first check the dimming interference, whether the audio and light power supply is 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 sound box system has noise, which is usually caused by unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal is grounded incorrectly, noise interference is likely to occur.
5、灯光失控的检查方法。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。
5. Inspection method for out-of-control lighting. 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 shield of the control line is subject to adverse interference, and whether the limit adjustment of the lamp is appropriate.
