会议室音响系统是会议室中应该配备的一种设备，但是很多会议室音响系统在使用的过程中会出现音频干扰的现象，对音响系统的使用有着较大的影响，所以应该积极的找出音频干扰的原因所在并给予解决。下面
山东音响厂家告诉你怎样避免会议室音响系统被音频干扰。
The audio system in the conference room is a kind of equipment that should be equipped in the conference room. However, audio interference will occur in the use of many audio systems in the conference room, which has a great impact on the use of the audio system. Therefore, we should actively find out the causes of audio interference and solve them. The following Shandong audio manufacturers tell you how to avoid audio interference in the audio system of the conference room.
1.如果会议室音响系统有电源接地不良、设备之间的地线接触不良、阻抗不匹配、电源未经&濒诲辩耻辞;净化&谤诲辩耻辞;处理、音频线与交流电线同管、同沟或同桥架铺设等问题时都会对音频信号产生杂波干扰，形成低频的交流&濒诲辩耻辞;嗡嗡&谤诲辩耻辞;声。为了避免电源引起的音频干扰，应该确保上述这些方面的问题都能有效解决。
1. If the audio system in the conference room has problems such as poor power grounding, poor ground wire contact between equipment, impedance mismatch, power supply not being "purified", audio cable and AC cable are laid in the same pipe, trench or bridge, it will cause noise 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 the above problems can be effectively solved.
2、避免设备之间的干扰
2. Avoid interference between equipment
&濒诲辩耻辞;啸叫&谤诲辩耻辞;是会议室音响系统比较常见的一种干扰现象，主要是由扬声器与麦克风之间发生正反馈而引起的，其原因就是麦克风离扬声器距离太近，或者麦克风指向了扬声器，此时&濒诲辩耻辞;空声&谤诲辩耻辞;就会由声波延时而产生并发生&濒诲辩耻辞;啸叫&谤诲辩耻辞;，使用时注意将设备拉开距离就能有效避免设备互扰造成的音频干扰。
"Howling" is a common interference phenomenon in the audio system of the conference room, which is mainly caused by 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. At this time, "empty sound" will be generated by sound wave delay and "howling". When using, pay attention to the distance between the equipment to effectively avoid audio interference caused by equipment mutual interference.
3、避免灯光干扰
3. Avoid light interference
如果会场采用镇流器方式间歇启动的照明灯，那么灯管激发时会产生高频辐射，并通过麦克风及其引线串入，出现&濒诲辩耻辞;哒哒&谤诲辩耻辞;的音频干扰声，此外，麦克风线离灯线太近也会出现干扰声，所以应该避免会议室音响系统的麦克风线离灯光过近。
If the lighting lamp is intermittently started in the way of ballast in the conference hall, high-frequency radiation will be generated when the lamp is excited, and the microphone and its leads will be connected in series, resulting in "clattering" audio interference sound. In addition, interference sound will also occur when the microphone line is too close to the lamp line, so it is necessary to avoid the microphone line of the conference room audio system being too close to the light.
在使用会议室音响系统的时候，如果稍有不注意就有可能发生音频干扰的现象，所以，即便使用的是质量很好会议室音响系统，但是在使用过程中仍然要注意一些事情，只要能够避免设备之间的干扰、电源干扰以及灯光干扰，那么就能有效避免出现各种干扰噪音。关注我们，了解对于音响

When using the conference room audio system, if you don't pay attention to it, audio interference may occur. Therefore, even if you use the conference room audio system with good quality, you should still pay attention to some things in the process of using it. As long as you can avoid interference among equipment, power supply and light, you can effectively avoid all kinds of interference noise. Follow us and learn about audio More about!
