会议室音响设备的正常切换顺序非常重要，如果不按标准程序操作，有时可能会直接损坏功放、调音台或其他配件。下面就跟着
山东会议室音响小编来聊聊这个内容。
The normal switching sequence of the audio equipment in the conference room is very important. If it is not operated according to the standard procedures, sometimes it may directly damage the power amplifier, mixer or other accessories. Now let's talk about this with the audio editor of Shandong conference room.
因为机器开关机的瞬间电流很大，直接开启一个设备的电源，瞬间电流会通过连接线传送到下一个设备，造成关联设备的工作电流瞬间增加并损坏设备。所以信号的输入应该是开机操作的方向，即播放设备（颁顿机、痴颁顿机、惭顿机、卡座、惭笔3等）&尘诲补蝉丑;&尘诲补蝉丑;信号处理设备（激励器、效果器、分频器）、均衡器等）--功率放大器--显示设备（电视机、投影仪等）。
Because the instantaneous current of the machine switching on and off is very large, directly turn on the power supply of one equipment, and the instantaneous current will be transmitted to the next equipment through the connecting line, causing the working current of the associated equipment to increase instantaneously and damaging the equipment. Therefore, the input of signal should be the direction of startup operation, that is, playback equipment (CD player, VCD player, MD Player, card holder, MP3 player, etc.) -- signal processing equipment (exciter, effector, frequency divider), equalizer, etc.) -- power amplifier -- display equipment (TV, projector, etc.).
关机时反向操作。在没有电源定序器的情况下，使用上述的上电和关机顺序。如果加了电源定序器，连接设备电源时必须考虑瞬时电流的影响。将设备的电源按指定的顺序连接到电源定序器上，并设置设备的开机顺序，以便在设备开关机时直接对电源定序器进行开关，以确保手术。
Reverse operation during shutdown. When there is no power sequencer, use the above power on and power off sequence. If a power sequencer is added, the influence of instantaneous current must be considered when connecting the power supply of the equipment. Connect the power supply of the equipment to the power sequencer in the specified order, and set the startup sequence of the equipment, so that the power sequencer can be directly switched on and off when the equipment is switched on and off, so as to ensure safe operation.
另外，一般情况下，即使经过严格调试，也不能避免故障的发生。要在日常工作中不断总结经验，经常分析失败的原因，这样才能保证音响设备的正常运行，保证会议的顺利进行。故障如：
In addition, in general, even after strict debugging, the failure cannot be avoided. We should constantly sum up experience in daily work and often analyze the reasons for failure, so as to ensure the normal operation of audio equipment and the smooth progress of the meeting. Faults such as:
大型会议，如大型会场，需要配备多台音箱，需要分别输出高、中、低音，以及监听音箱、监听音箱等。如果设备的输出端口不能满足需求，需要一个音频分配器将不同的信号分配给不同功能的功放，并一一调整。方法是调整一对时关闭其他扬声器，等调整到位后再调整其他扬声器。
Large conferences, such as large venues, need to be equipped with multiple speakers, which need to output high, medium and low tones, as well as monitor speakers, monitor speakers, etc. If the output port of the device cannot meet the demand, an audio distributor is needed to distribute different signals to different functional amplifiers and adjust them one by one. The method is to turn off other speakers when adjusting a pair, and then adjust other speakers after the adjustment is in place.
连接器和连接线是经常引起故障的主要因素之一。声音有时不存在或嘈杂，这通常会导致表演失败。事实上，这种故障很容易。演出前检查设备时，要检查所有线路，并用万用表一一测量其通断情况。发现问题及时处理，并预留常用连接线和适配器。
Connectors and connecting wires are one of the main factors that often cause failures. Sometimes the sound is absent or noisy, which usually leads to performance failure. In fact, this kind of fault is easy to eliminate. When checking the equipment before the performance, check all lines and measure the connection and disconnection of them one by one with a multimeter. If problems are found, handle them in time, and reserve common connecting lines and adapters.
当主声道出现故障无法播放时，可将监听音箱旋转到合适的角度临时更换主声道，以便会议继续进行。用于讲话的麦克风应该有备份，当麦克风静音时可以用备份代替。顿痴顿播放器也应该有备份，当顿痴顿播放器出现故障时可以更换。
When the main channel fails and cannot be played, the monitoring speaker can be rotated to an appropriate angle to temporarily replace the main channel so that the meeting can continue. The microphone used for speech should have a backup. When the microphone is silent, it can be replaced by a backup. The DVD player should also have a backup, which can be replaced when the DVD player fails.
总之，音响设备在会议的正常召开中扮演着重要的角色。如何对这些设备进行管理和维护，使其更有利于会议活动的开展，是设备维护人员的一项重要任务。更多相关内容，请访问我们的网站
