舞臺燈光音響設備正常與否，直接影響著(zhù)演出效果，所以無(wú)論是音響設備還是舞臺燈光設備都需要做好保養和維護工作，對出現問(wèn)題的線(xiàn)路和設備應及時(shí)維修，避免意外情況的出現，所以說(shuō)舞臺燈光音響設備演出前建議要檢查。
Whether the stage lighting and sound equipment is normal or not directly affects the performance effect, so both professional sound equipment and stage lighting equipment need to be well maintained. The lines and equipment that have problems should be repaired in time to avoid accidents. Therefore, it is recommended to check the stage lighting and sound equipment before the performance.
1、舞臺音響燈光設備外殼帶電現象檢查
1. Inspection of electrified shell of stage audio and lighting equipment
設備外殼帶電檢查是要檢查供電線(xiàn)路是否出現損壞情況，其次是線(xiàn)路相位是否正確，檢查設備接地和電壓是否正確。
The electrified inspection of the equipment shell is to check whether the power supply line is damaged first, and then whether the line phase is correct, and whether the equipment grounding and voltage are correct.
2、舞臺音響系統中音量不足的檢查
2. Inspection of insufficient volume in stage sound 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(shí)檢查功放和音箱的線(xiàn)路電平設置是否正確，還要了解音箱線(xiàn)連接是否牢固，以及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，壓限器的起控電平是否恰當。
Generally, if there is insufficient volume in the audio equipment, it is necessary to timely check whether the line level setting of the power amplifier and the speaker is correct, and also to know whether the speaker line is firmly connected, whether the phase of the power amplifier and the speaker is consistent, whether the attenuation amplitude of the equalizer is in a normal range, and whether the starting control level of the voltage limiter is appropriate.
3、舞臺音響產(chǎn)生干擾噪聲的檢查
3. Inspection of interference noise produced by stage sound
音響設備中如果有噪聲，就要檢查調光干擾，音響和燈光電源是否出現斷開(kāi)的情況，其次就要檢查燈光電源和控制線(xiàn)路是否離音頻信號線(xiàn)太近，有沒(méi)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，大都是由信號的傳輸不合理的情況所導致的。所以當信號線(xiàn)的屏蔽出現問(wèn)題，或者信號的接地不正確的時(shí)候，就容易出現噪聲干擾的情況。
If there is noise in professional audio equipment, first of all, 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. Generally, the noise in the speaker system is mostly caused by the unreasonable signal transmission. Therefore, when there is a problem with the shielding of the signal line or the grounding of the signal is incorrect, noise interference is easy to occur.
4、舞臺燈光失控的檢查
4. Inspection of stage lighting out of control
燈光失控就要檢查控制器的程序有沒(méi)有問(wèn)題，燈具的地址編碼有沒(méi)有出現問(wèn)題，控制線(xiàn)的接法是不是正確，還有需要檢查控制線(xiàn)的屏蔽有沒(méi)有受到不良干擾，燈具的限位調整是否恰當等。
If the light is out of control, it is necessary to check whether there is a problem with the program of the controller, whether there is a problem with the address code of the lamp, whether the connection method of the control line is correct, and whether the shielding of the control line is subject to adverse interference, whether the limit adjustment of the lamp is appropriate, etc.
5、舞臺電腦燈燈泡損壞檢查
5. Stage computer light bulb damage inspection
在
山東舞臺燈光音響中容易出現的就是燈泡易壞的情況，所以當出現問(wèn)題的時(shí)候，需要檢查安裝的燈泡是否牢靠，有沒(méi)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，電壓是否在正常的范圍內，有沒(méi)有使用電源開(kāi)關(guān)過(guò)于頻繁的情況。
In Shandong stage lighting and sound, the bulb is easy to break, so when there is a problem, first of all, it is necessary to check whether the installed bulb is secure, whether it is contaminated with dust and moisture, and whether the heat dissipation of the bulb is within the normal range, whether the voltage is within the normal range, and whether the power switch is used too frequently.
