音響工程一般都有大量的各種類型的線纜，這些線纜都需要預先鋪設在預埋的管線里，或者與系統連接后鋪設在控制室的某一個位置。下面來了解下音響工程各種線纜的鋪設內容吧。
Sound engineering generally has a large number of various types of cables, which need to be laid in the embedded pipeline in advance, or laid at a certain position in the control room after connecting with the system. Now let's learn about the laying of various cables in audio engineering.
鋪設前要將各種線纜按照設計要求分類放好線，放線時應該小心進行，盡量一一作好明顯的標記，作為安裝和檢修的查找依據，千萬不要將線纜弄亂，同時一定要留下充足的富余量，線纜中間不允許接頭，放好線后仔細檢查每條線是否有破損或質量低劣的情況，一旦有就應該立即全部更換。
Before laying, all kinds of cables should be placed in accordance with the design requirements. During the setting out, care should be taken to make obvious marks one by one as the basis for installation and maintenance. Do not mess up the cables. At the same time, sufficient surplus must be left. No joints are allowed in the middle of the cables. After placing the cables, carefully check whether each line is damaged or of poor quality. Once there is, it should be replaced immediately.
鋪設的線纜須依照設計和布局的位置準確到位；其次，因為線纜的鋪設只有一次機會，基本上沒有返工的可能，所以鋪設時要對照設計圖紙，掌握合理的方法進行，不能希望圖快而蠻干，否則就可能帶來不必要的麻煩。
The laid cables must be in place according to the design and layout; Secondly, because there is only one chance to lay the cable, there is basically no possibility of rework, so when laying, we should compare the design drawings and master a reasonable method. We can't expect the drawing to be fast and reckless, otherwise it may cause unnecessary trouble.
在線纜鋪設時要求施工人員相互協調配合，動作和用力要一致均勻，如果遇到轉彎、掛碰的時候，一定要小心，協同解決。
During cable laying, the construction personnel are required to coordinate with each other, and the action and force should be consistent and uniform. If there is a turning or hanging collision, be careful and solve it cooperatively.
另外，線纜鋪設工作中一項很重要，但又經常被人們忽略的工作是系統保護地線的鋪設和信號屏蔽線的鋪設，而且由于很少有人對這兩個線纜的概念進行清楚的區分，導致許多的工程技術人員也混淆不清，在實際工程施工中發生錯誤，這就是為什么許多音響系統總是有不掉的噪音，而有些系統的保護地線失去作用，設備外殼帶電的原因。
In addition, a very important but often neglected work in cable laying is the laying of system protective ground wire and signal shielding wire. Moreover, because few people clearly distinguish the concepts of these two cables, many professional engineering technicians are also confused, and errors occur in actual engineering construction, which is why many sound systems always have noise that cannot be eliminated, However, the protective ground wire of some systems fails to work, and the equipment shell is electrified.
此外關于
山東音響系統的屏蔽線，在鋪設時保護地線一般都須設置，而且應該連接良好，或者直接連接在機柜上，或者通過電源插座與設備本身的地線相通，鋪設完畢后逐一檢查各設備與地線的導通狀況；信號的屏蔽線路鋪設需要結合后面的線路連接情況，以及系統的要求和噪音情況而定。
In addition, as for the shielded wire of Shandong professional sound system, the protective ground wire must be set when laying, and it should be well connected, or directly connected to the cabinet, or connected to the ground wire of the equipment itself through the power socket. After laying, check the continuity of each equipment and the ground wire one by one; The laying of signal shielding line needs to be determined in combination with the later line connection, system requirements and noise conditions.
對于系統要求較高的工程或者現場電磁干擾較強的情況，在線纜鋪設時可以考慮單獨為音響系統埋設自己的信號真正的地線，埋設要求基本與電源地線要求基本一樣，只是要與電源地線區分開，而且埋設的必要性和可行性都要認真分析。
For projects with high system requirements or strong on-site electromagnetic interference, when laying the cable, you can consider embedding your own signal real ground wire for the sound system alone. The embedding requirements are basically the same as those of the power ground wire, but they should be separated from the power ground wire, and the necessity and feasibility of embedding should be carefully analyzed.
需要提醒大家的是：線纜的鋪設雖然看似簡單，進行起來時也比較快，但是如果只圖快，盲目蠻干，反倒容易導致施工工作受阻或者給工程留下隱患。更多注意事項您可以來網站

It is necessary to remind you that although the laying of cables seems simple and fast, if you only try to be fast and blindly act recklessly, it is easy to hinder the construction work or leave hidden dangers to the project.
