山东音响设备的性能和档次越来越高，音响工程技术的重要性就越来越强，下面为了更好的使用音响系统做工作，我们来讲讲音响系统对土建预留预埋配合要求。
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
在大会议室舞台前沿两侧的墙体，预留孔洞供安装左右主扩声超低音扬声器和拉声像扬声器，详见图纸。
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.
在大会议室观众厅和舞台区之间，预留两个通过管线的孔洞，开口0.5米*0.5米，供音响系统过管线，此孔洞一般预留在台口左右上方。
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.
在声控室预留一个0.5米*0.5米的孔洞直通吊顶上空，供敷设管线。
A 0.5m * 0.5m hole is reserved in the sound control room to lead directly above the ceiling for pipeline laying.
2、承载
2. Bearing
对于大会议室观众厅内扬声器的布置，根据声线分析，图纸中的左右扬声器组安装位置，安装在音桥内，详见图纸（音桥音箱平面图布置图），要求声桥的每个音箱室均应提供相应的承载量。
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、供电
3. Power supply
大会议室应提供二个集中供电点，采用单相叁线制配送。而且二个供电点的取电由同一路开关提供。建议双路供电，一次变电配送，音响系统的供电应与灯光照明供电分开，减少电源干扰。
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
声控室应设保护接地和工作接地，按中华人民共和国行业标准《民用建筑电器设计规范》闯骋闯/罢16－92中第21.6.4条所规定的原则处理。具体要求如下：
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:
单独设置专用接地装置，接地电阻不应大于2欧姆。
A special grounding device shall be set separately, and the grounding resistance shall not be greater than 2 ohms.
接共同接地网时，接地电阻不应大于1欧姆。
When connected to the common grounding grid, the grounding resistance should not be greater than 1 ohm.
此外要注意，同样的造价，不同的设计，工程质量会有高低之分；同样的设备，不同的设施，工程质量也会有高低之分，所以您在选择进行音响系统工程时要慎重考虑。您可以来我们网站
