我們在做舞臺燈光音響工程時，在安裝步驟經常會遇到線纜布線問題，布線工作沒做好，不僅會影響正常的工作需要，而且在聲音檢查期間和演出期間，對于故障線纜的追蹤排查也會變得非常困難。下面來分析下
山東舞臺燈光音響布置電源線常識內容。
When we are doing stage lighting and sound engineering, we often encounter cable wiring problems in the installation steps. Failure to do a good job in wiring will not only affect the normal work needs, but also make it very difficult to track and troubleshoot faulty cables during sound inspection and performance. Next, we will analyze the general knowledge of the power line layout of Shandong stage lighting and sound.
像三相饋送電纜/三相供電電纜這種重型的電源線纜應始終布置在舞臺以外。如果可以的話，對多余出來的電源線不要進行盤繞，而是應該將它們留在舞臺的下方均勻的擺放成八字形，請注意一定要讓它們遠離走道。
Heavy power cables such as three-phase feeder cables/three-phase power supply cables should always be arranged outside the stage. If possible, do not coil the extra power cables, but leave them at the bottom of the stage in an even splayed shape. Be sure to keep them away from the aisle.
當在主電源發射器到放大器機架之間連接較輕規格的線纜時，請盡可能使用合適長度的線纜，以避免在監聽工程師，吉他技術人員和其他的舞臺工作人員工作的區域中留下太多多余的（纏繞成卷）線纜。
When connecting light cables between the main power transmitter and the amplifier rack, please use cables of appropriate length as far as possible to avoid leaving too many redundant (coiled) cables in the work area of monitor engineers, guitar technicians and other stage staff.
在放大器機架下方以及放大器機架的后面這些常見的死角區域保留一段線纜，但是長度要短。
Keep a short length of cable in these common dead areas below and behind the amplifier rack.
盡量讓所有的連接到放大器的電源線所走的路徑保持一致，以避免在連接負載的時候出現線纜纏繞。確保電源線纜看起來整潔有序，如果線纜雜亂，應該重新布線。
Try to keep the path of all power cables connected to the amplifier consistent to avoid cable entanglement when connecting the load. Make sure the power cables look neat and orderly. If the cables are messy, they should be re routed.
在將線纜連接到舞臺的powerdrop時，好的做法是，使用少兩個供電線路，一條負責舞臺前部，另一條負責舞臺后部。在布置舞臺前方的供電線纜時，嘗試著在將其布置在鼓的架高平臺上，如果可能的話，沿著監聽設備線纜和信號線纜進行布置。
When connecting the cable to the stage's powerdrop, it is a good practice to use at least two power supply lines, one for the front of the stage and the other for the rear of the stage. When arranging the power supply cables in front of the stage, try to arrange them on the drum platform, if possible, along the monitoring equipment cables and signal cables.
舞臺前部的線纜主要負責為吉他音箱和貝斯音箱（后臺揚聲器）供電。舞臺后部的供電應該在監聽設備的后方，并且在布置線纜時應盡量跟隨監聽設備和信號線纜的布線進行走線。這條供電線纜通常需要為吉他手的調諧器和效果踏板，以及鍵盤供電。
The cables at the front of the stage are mainly used to power the guitar speakers and bass speakers (background speakers). The power supply at the rear of the stage should be at the rear of the monitoring equipment, and when laying cables, try to follow the wiring of the monitoring equipment and signal cables. This power cable usually needs to power the guitarist's tuner and effect pedal, as well as the keyboard.
同樣，要盡量避免使用太長的線纜。在允許的情況下，要盡量將所有多余的線纜塞入舞臺上的架高平臺下面，或者是放置在舞臺以外。這樣，當您需要移動powerdrop時，可以很容易的找到額外的線纜。需要注意的是永遠不要在布線時將線纜穿過表演區域（即鼓組和監聽設備之間的空間）。
Also, try to avoid using too long cables. If allowed, try to plug all redundant cables under the elevated platform on the stage, or place them outside the stage. In this way, when you need to move the powerdrop, you can easily find additional cables. It should be noted that never route the cable through the performance area (i.e. the space between the drum set and the monitoring device).
類似的常識也適用于布置揚聲器線纜。使用舞臺監聽設備時，請在揚聲器末端的線纜中預留出一段（保持松弛），否則一旦表演者要求移動監聽設備，您就不得不揭開所有的膠帶重新走線。更多的注意事項就來我們網站

Similar common sense applies to laying out speaker cables. When using the stage monitoring equipment, please reserve a section (keep loose) in the cable at the end of the speaker, otherwise once the performer requests to move the monitoring equipment, you will have to remove all the tape and reroute.
