山东舞台灯光音响的正常与否直接的影响着演出的效果,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的维修,避免意外情况的出现。
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.
产生干扰噪声的检查方法
Inspection method for generating interference noise
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的情况,就容易出现噪声干扰的情况。
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.
灯光失控的检查方法
Inspection method for light 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 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.
电脑灯灯泡损坏检查
Inspection for damage of computer lamp bulb
在舞台音响灯光中容易出现的就是灯泡易坏的情况,所以出现问题,就要检查安装的灯泡否牢靠,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,好需要检查的是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 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.
音视频系统中对视频图象的检查
Inspection of video image in audio and video system
如果在音响设备中出现视频图象不正常的情况,就需要检查节目制式是不是在正确的范围,设备外壳有没有带电的情况,其次还要检查信号屏蔽是不是容易受到高电平干扰,好要检查投影管是否在正常的范围内,液晶投影的灯泡的性能有没有出现问题。
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 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.
音响设备中无线话筒的声音不稳定
Unstable sound of wireless microphone in professional audio equipment
如果无线话筒不稳定的情况,就要检查声音不稳定的原因在哪里,是由于系统内有高频干扰源导致的,还是天线连接错误、接收机微调、话筒电池电量等连接设备出现问题导致的。
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.
