舞台音响设备产物有自己的生命周期，一旦使用到某一点，无法使用的设备会出现问题，建议是先要找出设备问题的关键点。那么你知道如何检查设备中的问题吗？以下是一些尝试的步骤！
Stage audio equipment products have their own life cycle. Once used to a certain point, unusable equipment will have problems. It is recommended to find out the key points of equipment problems first. Do you know how to check the problems in the equipment? Here are some steps to try!
先检查所有设备，待舞台音响设备无声后。检查所有音频设备是否已正确打开。各设备的接线，如音频线、信号线等是否连接正确，连接是否可靠，端口是否氧化；是否有音量调节按钮，如音量是否调节到合适的位置；混音器上每个通道的路径没有开关门；对于使用电容麦克风的舞台音响系统，检查是否应用了幻象电源等。
Check all equipment first, and wait until the stage sound equipment is silent. Check that all audio devices are turned on correctly. Whether the wiring of each equipment, such as audio line and signal line, is connected correctly, whether the connection is reliable, and whether the port is oxidized; Whether there is a volume adjustment button, such as whether the volume is adjusted to the appropriate position; The path of each channel on the mixer is not opened or closed; For stage sound system using condenser microphone, check whether phantom power supply is applied.
分步排查是在确认已经完成一步的基础上进行，舞台音响系统设备依然无声。您可以选择一个方向从前到后或从后到前进行检查。由前向后检查时，检查人员需要戴上监听耳机检查信号是否进入混音器，然后用电压表和万用表一一检查，逐级检查，直到有静音电平为止，同时，做出判断。如果音频系统中有任何设备没有输出，仍然是连接问题。
The step-by-step troubleshooting is carried out on the basis of confirming that one step has been completed, and the stage sound system equipment is still silent. You can choose a direction to check from front to back or from back to front. When checking from front to back, the inspectors need to wear monitoring headphones to check whether the signal enters the mixer, and then use a voltmeter and multimeter to check one by one, step by step, until there is a mute level, at the same time, make a judgment. If any device in the audio system does not output, it is still a connection problem.
比如，假如音响设备中呈现音量缺乏的状况，就要及时的查看功放和音箱的线路电平设置是不是准确，其次还要了解音箱线衔接是不是牢固，还有即是功放与音箱的相位是不是共同，均衡器衰减起伏是不是在正常的规模呢，压限器的起控电平是不是恰当。
For example, if there is a lack of volume in the audio equipment, it is necessary to timely check whether the line level setting of the power amplifier and the speaker is accurate. Secondly, it is also necessary to understand whether the connection of the speaker line is firm, whether the phase of the power amplifier and the speaker is common, whether the attenuation fluctuation of the equalizer is in the normal scale, and whether the starting control level of the voltage limiter is appropriate.
山东舞台音响设备中假如有噪声，首要就要查看调光搅扰，音响和灯火电源是不是呈现断开的状况，其次就要查看灯火电源和操控线路是不是离音频信号线太近，有没有呈现硅箱离音频设备太近的状况，通常状况下呈现音箱体系有噪声的状况，通常都是因为信号的传输不合理的状况所致使的，所以当信号线的屏蔽呈现疑问，或者信号的接地不准确的状况，就简单呈现噪声搅扰的状况。
If there is noise in Shandong stage sound equipment, first of all, check whether the dimming disturbance, sound 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 sound box system has noise, which is usually caused by the unreasonable signal transmission, Therefore, when the shielding of the signal line is in doubt, or the grounding of the signal is inaccurate, it simply presents the situation of noise disturbance.
