舞臺音響燈光的正常與否直接影響著演出的效果，所以不論是音響設備還是舞臺燈光設備都需要做好保養(yǎng)和維護工作，對出現(xiàn)問題的線路和設備應及時維修，避免意外情況的出現(xiàn)。如果現(xiàn)場出現(xiàn)
山東舞臺燈光音響問題，應該這樣處理：
Whether the stage audio and lighting are normal or not directly affects the performance effect, so both the audio equipment and the stage lighting equipment need to be well maintained. The faulty lines and equipment should be repaired in time to avoid accidents. If there is a problem with Shandong stage lighting and sound on the scene, it should be handled as follows:
1、舞臺音響燈光設備外殼有帶電現(xiàn)象的檢查順序。設備外殼帶電檢查的順序是要檢查供電線路是否出現(xiàn)損壞的情況，其次是線路相位是否正確，還要了解設備接地和電壓是否正確。
1. Inspection sequence for electrification of stage audio and lighting equipment shell. The order of live inspection of equipment shell is to check whether the power supply line is damaged, and then to check whether the line phase is correct, and to know whether the equipment grounding and voltage are correct.
2、音響系統(tǒng)中音量不足的情況檢查順序。一般情況下，如果音響設備中出現(xiàn)音量不足的情況，就要及時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，壓限器的起控電平是否恰當。
2. Check the order of insufficient volume in the audio system. Generally, if there is insufficient volume in the audio equipment, it is necessary to check whether the line level setting of the power amplifier and the speaker is correct in time. Secondly, it is also necessary to know whether the speaker cable connection is firm, and whether the phase of the power amplifier and the speaker is consistent, whether the attenuation amplitude of the equalizer is within the normal range, and whether the threshold level of the limiter is appropriate.
3、怎么檢查聲場中發(fā)生共振和聲反饋。如果在音響設備中出現(xiàn)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(jié)構(gòu)和裝飾是否合理，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(xiàn)過長的情況。
3. How to check resonance and acoustic feedback in the sound field. If resonance and acoustic feedback occur in the audio equipment, first of all, check whether the room frequency response has peaks, and then check whether the room structure and decoration are reasonable, and also check whether the frequency division point and bass gain are reasonable, and whether the room reverberation time is too long.
4、產(chǎn)生干擾噪聲的檢查方法。音響設備中如果有噪聲，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，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(xiàn)問題，或者信號的接地不正確，就容易出現(xiàn)噪聲干擾的情況。
4. Inspection method for generating interference noise. If there is noise in the audio equipment, first check the dimming interference, whether the audio and light power supply is 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 unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal is grounded incorrectly, noise interference is likely to occur.
5、燈光失控的檢查方法。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?shù)取?/div>
5. Inspection method for out-of-control lighting. If the light is out of control, it is necessary to check whether there is a problem with the controller program, whether there is a problem with the address code of the lamp, whether the connection of the control line is correct, whether the shield of the control line is subject to adverse interference, and whether the limit adjustment of the lamp is appropriate.
總之，只有了解到問題出現(xiàn)，才能針對這些做得更好，發(fā)揮到燈光音響好的效果。以上的內(nèi)容講解，希望可以幫助到您，您還有什么疑惑可以隨時來我們網(wǎng)站
