In addition, it also involves setting sound feedback to suppress noise in the audio system to prevent strong electrical interference with the grounding network
音响系统日常维护和保养中，必须满足现代会议室音响系统相关要求，针对性采取音响系统维护和保养可行性措施，以提升运行维护效率。具体日常维护和保养关键点为：
In the daily maintenance and upkeep of the sound system, it is necessary to meet the relevant requirements of modern conference room sound systems, and take targeted feasible measures for sound system maintenance and upkeep to improve operation and maintenance efficiency. The specific key points for daily maintenance and upkeep are:
具体要求
specific requirement
信息量大数据处理，信息接收上简单直观有序，满足商务谈判宾客会见以及产物演示等需求。通过相关图像声音以及文字等发布信息，在信息源上渠道更加广阔;以数字会议室音响中控系统控制其会议室音响系统的进程，通过声翻译系统实现不同种语言之间的正常交流。
Large amount of information processing, simple, intuitive, and orderly information reception, meeting the needs of business negotiations, guest meetings, and product demonstrations. By publishing information through relevant images, sounds, and text, the channels for information sources are wider; Control the progress of the conference room audio system through the digital conference room audio central control system, and achieve normal communication between different languages through the audio translation system.
音响系统维护和保养佳性能的发挥，必须通过减少平时运转故障，从防尘防虫防潮防高温防震动等方面着手，进一步提高会议室音响系统运行效率。
The best performance of sound system maintenance and upkeep must be achieved by reducing normal operating faults, starting from dust, insect, moisture, high temperature, and vibration prevention, to further improve the operational efficiency of the conference room sound system.
音响系统设备正常操作前，开机检查效果器话筒，复对点歌系统实施功能性开放，关机顺序与之相反。即，开机播放颁顿机，再行打开前与后，并将功放音量电位器开到小;关机环节先关功放，后关闭前端设备，可直接保护音箱与功放。还有就是，后关闭时，先将功放音量电位器开到小，复关闭颁顿和惭滨颁机。
Before the sound system equipment operates normally, turn on the power to check the microphone of the effector, and implement functional opening for the repeat song system. The shutdown sequence is the opposite. That is, turn on the CD player, turn on the front and back, and turn down the power amplifier volume potentiometer; During the shutdown process, turn off the power amplifier first, and then turn off the front-end device to directly protect the speaker and power amplifier. In addition, when closing later, first turn down the volume potentiometer of the amplifier, and then turn off the CD and MIC.
防尘环节，使用干净和潮湿的棉布对机器表面进行擦拭并清理，避免使用挥发性溶剂和水;停用环节注意防灰尘进入音响设备中。音响打开或断开中，紧握连接器，避免抓线缆，以损坏线缆或发生触电事故。维修要选择技术人员，以免损伤维修者，对存在故障的音响连接线是要及时更换。
During the dust prevention process, use a clean and damp cotton cloth to wipe and clean the surface of the machine, avoiding the use of volatile solvents and water; Pay attention to preventing dust from entering the audio equipment during the shutdown process. When the audio is turned on or off, grip the connector tightly to avoid grabbing the cable, in order to damage the cable or cause an electric shock accident. Technical personnel should be selected for maintenance to avoid damaging the repairer, and faulty audio connection cables should be replaced in a timely manner.
夏季使用中，合理放热，以稳定电子管机的灵敏度，稳定音响系统工作环节的干湿度，保持室内空气流通，远离热辐射源热源并保持机械干燥。
During summer use, heat should be released reasonably to stabilize the sensitivity of the electronic tube machine, stabilize the humidity and humidity of the sound system during operation, maintain indoor air circulation, stay away from heat radiation sources, and maintain mechanical dryness.
音响喇叭防潮湿，可减轻喇叭振膜老化现象导致的音质下降。主要受潮湿后，喇叭软胶圈边缘易老化和破烂，导致音响内部部分金属生锈腐蚀导致音响系统故障，甚无法正常运转。故此，音响使用中，必须置于干燥的位置中;长期不用时，更要防潮防尘;高温天气或季节，每天通电半小时，可通过通电来产生热量达到去潮效果。
The sound horn is moisture-proof and can reduce the degradation of sound quality caused by the aging of the horn diaphragm. After being mainly affected by moisture, the edges of the horn's soft rubber ring are prone to aging and wear, leading to rust and corrosion of some metal inside the audio system, resulting in audio system malfunction and even inability to operate normally. Therefore, when using the audio system, it must be placed in a dry location; When not in use for a long time, it is even more important to prevent moisture and dust; In hot weather or seasons, if you power on for half an hour every day, you can generate heat to achieve a moisture removal effect.
基于音响系统中故障分析及其运行维护关键点的分析，提出了音响系统的运行维护意见和建议。在音响系统使用中，从防潮防震防过载入手，着重对调音台功放衰减器位置进行缓慢调整。调音台推子中避免液体杂物和灰尘等落入其缝隙中;避免系统各设备励磁涌流而损坏输入。系统中的插接件严禁带电插拔，以免对后设备造成瞬时过载电流冲击。功放和音箱系统信号避免过强。
Based on the analysis of faults and key points of operation and maintenance in the audio system, suggestions and suggestions for the operation and maintenance of the audio system are proposed. In the use of sound systems, starting from moisture-proof, shockproof, and overload proof, the focus is on slowly adjusting the position of the power amplifier attenuator on the mixing table. Avoid liquid debris and dust from falling into the gaps in the mixer pusher; Avoid damaging the input due to excitation inrush currents of various equipment in the system. It is strictly prohibited to plug and unplug the connectors in the system with power to avoid causing instantaneous overload current impact on the rear equipment. Avoid strong signals in the amplifier and speaker systems.
