舞臺燈光音響設(shè)備正常與否，直接影響著演出效果，所以無論是音響設(shè)備還是舞臺燈光設(shè)備都需要做好保養(yǎng)和維護(hù)工作，對出現(xiàn)問題的線路和設(shè)備應(yīng)及時(shí)維修，避免意外情況的出現(xiàn)，所以說舞臺燈光音響設(shè)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(shè)備外殼帶電現(xiàn)象檢查
1. Inspection of electrified shell of stage audio and lighting equipment
設(shè)備外殼帶電檢查是要檢查供電線路是否出現(xiàn)損壞情況，其次是線路相位是否正確，檢查設(shè)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(tǒng)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(shè)備中出現(xiàn)音量不足的情況，就要及時(shí)檢查功放和音箱的線路電平設(shè)置是否正確，還要了解音箱線連接是否牢固，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(dāng)。
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(shè)備中如果有噪聲，就要檢查調(diào)光干擾，音響和燈光電源是否出現(xiàn)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(xiàn)硅箱離音頻設(shè)備太近的情況。一般情況下出現(xiàn)音箱系統(tǒng)有噪聲的情況，大都是由信號的傳輸不合理的情況所導(dǎo)致的。所以當(dāng)信號線的屏蔽出現(xiàn)問題，或者信號的接地不正確的時(shí)候，就容易出現(xiàn)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有問題，燈具的地址編碼有沒有出現(xiàn)問題，控制線的接法是不是正確，還有需要檢查控制線的屏蔽有沒有受到不良干擾，燈具的限位調(diào)整是否恰當(dāng)?shù)取?/div>
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(xiàn)的就是燈泡易壞的情況，所以當(dāng)出現(xiàn)問題的時(shí)候，需要檢查安裝的燈泡是否牢靠，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(nèi)，電壓是否在正常的范圍內(nèi)，有沒有使用電源開關(guān)過于頻繁的情況。
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.
