顧名思義，會議音響主要用于會議廳、報告廳等比較嚴肅的場所中，所以異常聲音是不能出現(xiàn)的，否則會影響到工作。那么如果會議音響設備連接出現(xiàn)交流聲了怎么辦呢？接下來講解處理方法。
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.
弱信號設備電源與強信號設備電源成組連接。CD、卡座、效果器、混音器、壓縮限幅器、均衡器等弱信號聲源設備接在同一組電源上，強信號功放接在另一組電源上，可以避免電源在傳導模式交流噪聲干擾。
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.
連接清潔電源時，應設計單獨的電源變壓器。可以無條件使用一套獨立的電源，與空調(diào)、照明等設備分開。或者使用隔離電源變壓器等。這些都是有效的措施。
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.
遠距離傳輸信號的傳輸方式為平衡或平衡隔離變壓器，短距離傳輸方式可采用非平衡方式。一般采用平衡隔離變壓器的傳輸方式。兩端應有平衡變壓器，屏蔽層的一端應接地，但也可懸空不接。接地可以起到屏蔽作用，還可以防止設備漏電引起的觸電事故。不接地時，兩端的平衡變壓器可以起到絕緣作用，平衡變壓器的中心接地以釋放靜電。
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.
在電源干擾嚴重的情況下，設備應分相連接，將小信號音頻設備和監(jiān)控設備的電源連接在一起。在三相電源中，選擇嗡嗡聲干擾小的一相連接，另外兩相連接到大信號功放，可以減少來自電源的交流噪聲干擾。
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.
兩臺音響設備之間不應有直流電路連接；檢查
會議音響設備的電源是否臟了；是不是部分設備的接地問題；另外，檢查設備連接是否有干擾（混亂與否）；看是否受光干擾，一般情況下，如果音響里的交流聲音很大，就是功放有問題。如果放大器的信噪比不是很好，就會發(fā)出很大的聲音。
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.
會議音響設備連接出現(xiàn)交流聲怎么辦？所以以上的內(nèi)容大家可以當做問題的借鑒。當然，為了預防會議音響設備連接時出現(xiàn)類似交流聲等異常問題，就要提前做好相應的預防措施才行。更多內(nèi)容就來我們網(wǎng)站
