山東音響設備的性能和檔次越來越高，音響工程技術的重要性就越來越強，下面為了更好的使用音響系統做工作，我們來講講音響系統對土建預留預埋配合要求。
The performance and grade of Shandong audio equipment are getting higher and higher, and the importance of professional audio engineering technology is becoming stronger and stronger. Next, in order to better use the audio system to do work, let's talk about the requirements of the audio system for civil engineering reservation and embedding.
1、孔洞
1. Hole
在大會議室舞臺前沿兩側的墻體，預留孔洞供安裝左右主擴聲超低音揚聲器和拉聲像揚聲器，詳見圖紙。
Holes are reserved in the walls on both sides of the front edge of the stage in the large conference room for the installation of left and right main sound reinforcement subwoofers and sound and image speakers. See the drawings for details.
在大會議室觀眾廳和舞臺區之間，預留兩個通過管線的孔洞，開口0.5米*0.5米，供音響系統過管線，此孔洞一般預留在臺口左右上方。
Between the auditorium and the stage area of the large conference room, two holes through the pipeline are reserved, with an opening of 0.5m * 0.5m, for the sound system to pass through the pipeline. This hole is generally reserved above the left and right of the entrance.
在聲控室預留一個0.5米*0.5米的孔洞直通吊頂上空，供敷設管線。
A 0.5m * 0.5m hole is reserved in the sound control room to lead directly above the ceiling for pipeline laying.
2、承載
2. Bearing
對于大會議室觀眾廳內揚聲器的布置，根據聲線分析，圖紙中的左右揚聲器組安裝位置，安裝在音橋內，詳見圖紙（音橋音箱平面圖布置圖），要求聲橋的每個音箱室均應提供相應的承載量。
For the layout of loudspeakers in the auditorium of the large conference room, according to the sound line analysis, the installation positions of the left and right loudspeaker groups in the drawing are installed in the sound bridge. See the drawing (sound bridge sound box layout plan) for details. It is required that each sound box room of the sound bridge should provide corresponding bearing capacity.
3、供電
3. Power supply
大會議室應提供二個集中供電點，采用單相三線制配送。而且二個供電點的取電由同一路開關提供。建議雙路供電，一次變電配送，音響系統的供電應與燈光照明供電分開，減少電源干擾。
The large conference room shall be provided with two centralized power supply points, which shall be distributed by single-phase three wire system. And the power of the two power supply points is provided by the same switch. It is suggested that two-way power supply, primary power transformation and distribution, and the power supply of sound system should be separated from the power supply of lighting to reduce power interference.
4、接地
4. Grounding
聲控室應設保護接地和工作接地，按中華人民共和國行業標準《民用建筑電器設計規范》JGJ/T16－92中第21.6.4條所規定的原則處理。具體要求如下：
The sound control room shall be equipped with protective grounding and working grounding, which shall be handled according to the principles specified in article 21.6.4 of the industrial standard of the people's Republic of China code for design of electrical appliances in civil buildings jgj/t16-92. Specific requirements are as follows:
單獨設置專用接地裝置，接地電阻不應大于2歐姆。
A special grounding device shall be set separately, and the grounding resistance shall not be greater than 2 ohms.
接共同接地網時，接地電阻不應大于1歐姆。
When connected to the common grounding grid, the grounding resistance should not be greater than 1 ohm.
此外要注意，同樣的造價，不同的設計，工程質量會有高低之分；同樣的設備，不同的設施，工程質量也會有高低之分，所以您在選擇進行音響系統工程時要慎重考慮。您可以來我們網站

In addition, it should be noted that the same cost, different design, project quality will be high or low; The engineering quality of the same equipment and different facilities will also be high or low, so you should carefully consider when choosing to carry out the sound system engineering.
