舞臺音響設備產品有自己的生命周期，一旦使用到某一點，無法使用的設備會出現問題，建議是先要找出設備問題的關鍵點。那么你知道如何檢查設備中的問題嗎？以下是一些嘗試的步驟！
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!
先檢查所有設備，待舞臺音響設備無聲后。檢查所有音頻設備是否已正確打開。各設備的接線，如音頻線、信號線等是否連接正確，連接是否可靠，端口是否氧化；是否有音量調節按鈕，如音量是否調節到合適的位置；混音器上每個通道的路徑沒有開關門；對于使用電容麥克風的舞臺音響系統，檢查是否應用了幻象電源等。
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.
分步排查是在確認已經完成一步的基礎上進行，舞臺音響系統設備依然無聲。您可以選擇一個方向從前到后或從后到前進行檢查。由前向后檢查時，檢查人員需要戴上監聽耳機檢查信號是否進入混音器，然后用電壓表和萬用表一一檢查，逐級檢查，直到有靜音電平為止，同時，做出判斷。如果音頻系統中有任何設備沒有輸出，仍然是連接問題。
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，假如音響設備中呈現音量缺乏的狀況，就要及時的查看功放和音箱的線路電平設置是不是準確，其次還要了解音箱線銜接是不是牢固，還有即是功放與音箱的相位是不是共同，均衡器衰減起伏是不是在正常的規模呢，壓限器的起控電平是不是恰當。
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.
山東舞臺音響設備中假如有噪聲，首要就要查看調光攪擾，音響和燈火電源是不是呈現斷開的狀況，其次就要查看燈火電源和操控線路是不是離音頻信號線太近，有沒有呈現硅箱離音頻設備太近的狀況，通常狀況下呈現音箱體系有噪聲的狀況，通常都是因為信號的傳輸不合理的狀況所致使的，所以當信號線的屏蔽呈現疑問，或者信號的接地不準確的狀況，就簡單呈現噪聲攪擾的狀況。
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.
