顾名思义，会议音响主要用于会议厅、报告厅等比较严肃的场所中，所以异常声音是不能出现的，否则会影响到工作。那么如果会议音响设备连接出现交流声了怎么办呢？接下来讲解处理方法。
As the name implies, the conference sound is mainly used in the conference hall, lecture hall and other serious places, so abnormal sound cannot appear, otherwise it will affect the work. So what if the meeting audio equipment is connected to an ac sound? Here's how to do it.
弱信号设备电源与强信号设备电源成组连接。颁顿、卡座、效果器、混音器、压缩限幅器、均衡器等弱信号声源设备接在同一组电源上，强信号功放接在另一组电源上，可以避免电源在传导模式交流噪声干扰。
The power supply of the weak signal device is connected to the power supply of the strong signal device in groups. Weak signal sound source equipment such as CD, cassette, effector, mixer, compression limiter and equalizer are connected to the same set of power supplies, while strong signal amplifier is connected to another set of power supplies, which can avoid ac noise interference from the power supply in conduction mode.
连接清洁电源时，应设计单独的电源变压器。可以无条件使用一套独立的电源，与空调、照明等设备分开。或者使用隔离电源变压器等。这些都是有效的措施。
A separate power supply transformer shall be designed when connecting the cleaning power supply. Can use a set of independent power supply unconditionally, separated from air conditioning, lighting and other equipment. Or use isolated power transformers. These are all effective measures.
远距离传输信号的传输方式为平衡或平衡隔离变压器，短距离传输方式可采用非平衡方式。一般采用平衡隔离变压器的传输方式。两端应有平衡变压器，屏蔽层的一端应接地，但也可悬空不接。接地可以起到屏蔽作用，还可以防止设备漏电引起的触电事故。不接地时，两端的平衡变压器可以起到绝缘作用，平衡变压器的中心接地以释放静电。
The transmission mode of the long distance transmission signal is balanced or balanced isolation transformer, and the short distance transmission mode can be unbalanced. Balanced isolation transformer is generally used for transmission. There should be a balance transformer at both ends, one end of the shielding layer should be connected to the ground, but it can also be suspended. Grounding can shield the device and prevent electric shock accidents caused by electric leakage. When not grounded, the balance transformer at both ends can play an insulating role, the center of the balance transformer is grounded to release static electricity.
在电源干扰严重的情况下，设备应分相连接，将小信号音频设备和监控设备的电源连接在一起。在叁相电源中，选择嗡嗡声干扰小的一相连接，另外两相连接到大信号功放，可以减少来自电源的交流噪声干扰。
In the case of serious power interference, the equipment should be separately connected, connecting the power supply of small signal audio equipment and monitoring equipment together. In the three-phase power supply, choose a connection with low buzzing interference, and the other two are connected to a large signal amplifier, which can reduce the AC noise interference from the power supply.
两台音响设备之间不应有直流电路连接；检查设备的电源是否脏了；是不是部分设备的接地问题；另外，检查设备连接是否有干扰（混乱与否）；看是否受光干扰，一般情况下，如果音响里的交流声音很大，就是功放有问题。如果放大器的信噪比不是很好，就会发出很大的声音。
There should be no DIRECT current connection between two audio equipment; Check whether the power supply of meeting audio equipment is dirty; Is not part of the equipment grounding problem; In addition, check the device connection for interference (confusion or not); See whether to suffer light interference, normally, if the communication sound in acoustics is very big, it is the result put has a problem. If the amplifier's signal-to-noise ratio is not very good, it will make a lot of noise.
