我们在做舞台灯光音响工程时，在安装步骤经常会遇到线缆布线问题，布线工作没做好，不仅会影响正常的工作需要，而且在声音检查期间和演出期间，对于故障线缆的追踪排查也会变得非常困难。下面来分析下
山东舞台灯光音响布置电源线常识内容。
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.
像叁相馈送电缆/叁相供电电缆这种重型的电源线缆应始终布置在舞台以外。如果可以的话，对多余出来的电源线不要进行盘绕，而是应该将它们留在舞台的下方均匀的摆放成八字形，请注意一定要让它们远离走道。
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.
当在主电源发射器到放大器机架之间连接较轻规格的线缆时，请尽可能使用合适长度的线缆，以避免在监听工程师，吉他技术人员和其他的舞台工作人员工作的区域中留下太多多余的（缠绕成卷）线缆。
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.
在放大器机架下方以及放大器机架的后面这些常见的死角区域保留一段线缆，但是长度要短。
Keep a short length of cable in these common dead areas below and behind the amplifier rack.
尽量让所有的连接到放大器的电源线所走的路径保持一致，以避免在连接负载的时候出现线缆缠绕。确保电源线缆看起来整洁有序，如果线缆杂乱，应该重新布线。
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.
在将线缆连接到舞台的辫辞飞别谤诲谤辞辫时，好的做法是，使用少两个供电线路，一条负责舞台前部，另一条负责舞台后部。在布置舞台前方的供电线缆时，尝试着在将其布置在鼓的架高平台上，如果可能的话，沿着监听设备线缆和信号线缆进行布置。
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.
舞台前部的线缆主要负责为吉他音箱和贝斯音箱（后台扬声器）供电。舞台后部的供电应该在监听设备的后方，并且在布置线缆时应尽量跟随监听设备和信号线缆的布线进行走线。这条供电线缆通常需要为吉他手的调谐器和效果踏板，以及键盘供电。
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.
同样，要尽量避免使用太长的线缆。在允许的情况下，要尽量将所有多余的线缆塞入舞台上的架高平台下面，或者是放置在舞台以外。这样，当您需要移动辫辞飞别谤诲谤辞辫时，可以很容易的找到额外的线缆。需要注意的是永远不要在布线时将线缆穿过表演区域（即鼓组和监听设备之间的空间）。
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).
类似的常识也适用于布置扬声器线缆。使用舞台监听设备时，请在扬声器末端的线缆中预留出一段（保持松弛），否则一旦表演者要求移动监听设备，您就不得不揭开所有的胶带重新走线。更多的注意事项就来我们网站

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.
