会议室音响系统是会议室应该配备的一种设备，但是很多会议室音响系统在使用过程中会出现音频干扰，对音响系统的使用影响很大，所以我们应该主动找出造成音频干扰的原因，定位并解决。下面厂家告诉你会议室音响系统如何避免音频干扰。
The conference room sound system is a kind of equipment that the conference room should be equipped with. However, many conference room sound systems will have audio interference during use, which will have a great impact on the use of the sound system. Therefore, we should take the initiative to find out the causes of audio interference, locate and solve them. The following manufacturers tell you how to avoid audio interference in the conference room sound system.
如果会议室音响系统出现电源接地不良、设备间地线接触不良、阻抗不匹配、电源未经&濒诲辩耻辞;净化&谤诲辩耻辞;处理、音频线与交流线在同一管道、同一沟槽或在同一个电桥等处都会对音频信号产生杂波干扰，形成低频交流&濒诲辩耻辞;嗡嗡&谤诲辩耻辞;声。为了避免电源造成的音频干扰，应确保这些问题能够得到有效解决。
If the sound system in the conference room has poor power grounding, poor ground wire contact between equipment, mismatched impedance, the power supply has not been "purified", and the audio line and the AC line are in the same pipe, the same groove or the same bridge, it will cause clutter interference to the audio signal, forming a low-frequency AC "buzz". In order to avoid audio interference caused by power supply, it is necessary to ensure that these problems can be effectively solved.
避免设备之间的干扰。&濒诲辩耻辞;啸叫&谤诲辩耻辞;是会议室音响系统中常见的干扰现象。它主要是由扬声器和麦克风之间的正反馈引起的。原因是麦克风离扬声器太近，或者麦克风指向扬声器。声波延迟会产生&濒诲辩耻辞;空声&谤诲辩耻辞;，并会出现&濒诲辩耻辞;啸叫&谤诲辩耻辞;。使用时注意设备相互远离，可以有效避免设备相互干扰造成的音频干扰。
Avoid interference between devices. "Howling" is a common interference phenomenon in conference room sound system. It is mainly caused by the positive feedback between the speaker and the microphone. The reason is that the microphone is too close to the speaker, or the microphone points to the speaker. Sound wave delay will produce "empty sound" and "howling". When using, pay attention to the distance between the devices, which can effectively avoid the audio interference caused by the mutual interference of the devices.
避免光线干扰。如果在场馆内间歇性使用镇流器型照明灯，激发灯时会产生高频辐射，将麦克风与其引线串联，产生&濒诲辩耻辞;哒哒&谤诲辩耻辞;的音频干扰声。太近也会造成干扰，所以应避免会议室音响系统的麦克风线太靠近灯光。
Avoid light interference. If ballast type lighting lamps are used intermittently in the venue, high-frequency radiation will be generated when the lamps are excited. Connect the microphone in series with its leads to produce "clatter" audio interference sound. Too close will also cause interference, so the microphone line of the conference room sound system should not be too close to the light.
使用
山东会议室音响系统时，如果不小心，可能会出现音频干扰。因此，即使您使用了高质量的会议室音响系统，在使用过程中还是需要注意一些事项。只要能避免设备间的干扰、电源干扰、灯光干扰，那么各种干扰噪声都能有效避免。
Audio interference may occur if you are not careful when using Shandong conference room audio system. Therefore, even if you use a high-quality conference room sound system, you still need to pay attention to some matters during the use. As long as the interference between equipment, power supply and lighting can be avoided, all kinds of interference and noise can be effectively avoided.
