        音響燈光設備外殼有帶電現象的檢查順序
        Inspection sequence of electrified enclosure of audio and lighting equipment
        設備外殼帶電檢查的順序首先是要檢查供電線路是否出現損壞的情況,其次是線路相位是否正確,然后還要了解設備接地和電壓是否正確。
        The order of live inspection of equipment shell is to check whether the power supply line is damaged, then whether the line phase is correct, and then whether the equipment grounding and voltage are correct.
        怎么檢查聲場中發生共振和反饋
        How to check resonance and feedback in the sound field
        如果在專業音響設備中出現共振和聲反饋的情況,首先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,最好還要檢查分頻點和低音增益是否合理,房間混響時間是否有出現過長的情況。
        If there is resonance and acoustic feedback in professional audio equipment, first check whether the room frequency response has a peak point, and whether the room structure and decoration are reasonable. It is best to check 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
        專業音響設備中如果有噪聲,首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。
        If there is noise in professional audio equipment, first check the dimming interference and whether the audio and light power supply are disconnected. Secondly, 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.

        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。
        Generally, the noise in the speaker system is usually caused by the unreasonable signal transmission. Therefore, when the shielding of the signal line is faulty or the signal grounding is incorrect, the noise interference is easy to occur.
        專業音響系統音量不足的情況檢查順序
        Inspection sequence for insufficient volume of professional sound system
        一般情況下如果專業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?
        Generally, if the volume is insufficient in professional audio equipment, it is necessary to timely check whether the line level setting of power amplifier and speaker is correct. Secondly, it is also necessary to understand whether the speaker line connection is firm, whether the phase of power amplifier and speaker is consistent, and whether the attenuation amplitude of equalizer is in the normal range? Is the starting control level of the voltage limiter appropriate?
        燈光失控的檢查方法
        Inspection method of out of control light
        燈光失控首先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,燈具的限位調整是否恰當等。
        If the light is out of control, first 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, whether the shielding of the control line is subject to adverse interference, and whether the limit adjustment of the lamp is appropriate.
        電腦燈燈泡損壞檢查
        Computer lamp bulb damage inspection
        在舞臺音響燈光中最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,最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 the stage sound and lighting, the most likely thing is that the bulb is easy to break. Therefore, in case of problems, it is necessary to check whether the installed bulb is reliable and whether it is contaminated with dust and moisture. In addition, it is also necessary to check whether the heat dissipation of the bulb is within the normal range. It is best to check whether the voltage is within the normal range and whether the power switch is used too frequently.
        專業音響設備中無線話筒的聲音不穩定:
        The sound of wireless microphones in professional audio equipment is unstable:
        如果無線話筒有不穩定的情況,首先就要檢查聲音不穩定的原因在哪里,是由于系統內有高頻干擾源導致的,還是天線連接錯誤、接收機微調、話筒電池電量等連接設備出現問題導致的。
        If the wireless microphone is unstable, first check the cause of the sound instability, whether it is caused by high-frequency interference sources in the system, or problems with connecting equipment such as antenna connection error, receiver fine-tuning, microphone battery power, etc.
        音視頻系統中對視頻圖像的檢查
        Inspection of video image in audio and video system
        如果在專業音響設備中出現視頻圖象不正常的情況,首先就需要檢查節目制式是不是在正確的范圍,設備外殼有沒有帶電的情況,其次還要檢查信號屏蔽是不是容易受到高電平干擾,最好要檢查投影管是否在正常的范圍內,液晶投影的燈泡的性能有沒有出現問題。舞臺燈光音響設備
        If the video image is abnormal in professional audio equipment, first of all, it is necessary to check whether the program system is in the correct range and whether the equipment shell is charged. Secondly, it is also necessary to check whether the signal shielding is vulnerable to high-level interference. It is best to check whether the projection tube is in the normal range and whether there is a problem with the performance of the liquid crystal projection bulb. Stage lighting and sound equipment
