舞臺音響燈光的正常與否直接的影響著演出的效果，那么，我們對舞臺燈光音響設備使用的同時，也需要我們對它定期的檢查，檢查有哪些常識要知道呢？
Whether the stage sound and lighting are normal or not directly affects the performance effect. So, when we use the stage light and lighting equipment, we also need to check it regularly. What common sense should we know?
電腦燈燈泡損壞檢查
Inspection for damage of computer lamp bulb
在
山東舞臺燈光音響中很容易出現的就是燈泡易壞的情況，所以出現問題，就要檢查安裝的燈泡否牢靠，有沒有沾染塵土和水氣，還有就是要檢查燈泡的散熱是不是在正常范圍內，很好需要檢查的是電壓是否在正常的范圍內，有沒有使用電源開關過于頻繁的情況。
In Shandong stage lighting and audio, it is easy to see that the bulb is easy 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. It is good to check whether the voltage is within the normal range and whether the power switch is used too frequently.
音響系統中音量不足的情況檢查順序
Inspection sequence of insufficient volume in professional audio system
一般情況下如果音響設備中出現音量不足的情況，就要及時的檢查功放和音箱的線路電平設置是否正確，其次還要了解音箱線連接是否牢固，還有就是功放與音箱的相位是否一致，均衡器衰減幅度是否在正常的范圍呢，壓限器的起控電平是否恰當。
In general, if the volume of professional audio equipment is insufficient, it is necessary to timely check whether the line level setting of the power amplifier and the speaker is correct. Secondly, it is necessary to know whether the speaker line is firmly connected, whether the phase of the power amplifier and the speaker is consistent, whether the attenuation of the equalizer is within the normal range, and whether the starting control level of the voltage limiter is appropriate.
怎么檢查聲場中發生共振和反饋
How to check resonance and feedback in the sound field
如果在音響設備中出現共振和聲反饋的情況，要檢查房間頻響是否有峰點，還有就是要檢查房間結構和裝飾是否合理，很好還要檢查分頻點和低音增益是否合理，房間混響時間是否出現過長的情況。
If resonance and acoustic feedback occur in professional audio equipment, first of all, it is necessary to check whether there is a peak in the room frequency response, whether the room structure and decoration are reasonable, and whether the frequency division point and bass gain are reasonable, and whether the room reverberation time is too long.
產生干擾噪聲的檢查方法
Inspection method for generating interference noise
音響設備中如果有噪聲，先就要檢查調光干擾，音響和燈光電源是否出現斷開的情況，其次就要檢查燈光電源和控制線路是否離音頻信號線太近，有沒有出現硅箱離音頻設備太近的情況。一般情況下出現音箱系統有噪聲的情況，通常都是由于信號的傳輸不合理的情況所導致的，所以當信號線的屏蔽出現問題，或者信號的接地不正確的情況，就容易出現噪聲干擾的情況。
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.
The above is the basic knowledge about stage lighting and sound detection. I hope it will help you. If you want to know more, please follow our website http://www.zkvd.cn , to provide you with more relevant information.
