會議室音響系統(tǒng)是會議室中應(yīng)該配備的一種設(shè)備，但是很多會議室音響系統(tǒng)在使用的過程中會出現(xiàn)音頻干擾的現(xiàn)象，對音響系統(tǒng)的使用有著較大的影響，所以應(yīng)該積極的找出音頻干擾的原因所在并給予解決。下面
山東音響廠家告訴你怎樣避免會議室音響系統(tǒng)被音頻干擾。
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.如果會議室音響系統(tǒng)有電源接地不良、設(shè)備之間的地線接觸不良、阻抗不匹配、電源未經(jīng)“凈化”處理、音頻線與交流電線同管、同溝或同橋架鋪設(shè)等問題時都會對音頻信號產(chǎn)生雜波干擾，形成低頻的交流“嗡嗡”聲。為了避免電源引起的音頻干擾，應(yīng)該確保上述這些方面的問題都能有效解決。
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、避免設(shè)備之間的干擾
2. Avoid interference between equipment
“嘯叫”是會議室音響系統(tǒng)比較常見的一種干擾現(xiàn)象，主要是由揚聲器與麥克風(fēng)之間發(fā)生正反饋而引起的，其原因就是麥克風(fēng)離揚聲器距離太近，或者麥克風(fēng)指向了揚聲器，此時“空聲”就會由聲波延時而產(chǎn)生并發(fā)生“嘯叫”，使用時注意將設(shè)備拉開距離就能有效避免設(shè)備互擾造成的音頻干擾。
"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、避免燈光干擾
3. Avoid light interference
如果會場采用鎮(zhèn)流器方式間歇啟動的照明燈，那么燈管激發(fā)時會產(chǎn)生高頻輻射，并通過麥克風(fēng)及其引線串入，出現(xiàn)“噠噠”的音頻干擾聲，此外，麥克風(fēng)線離燈線太近也會出現(xiàn)干擾聲，所以應(yīng)該避免會議室音響系統(tǒng)的麥克風(fēng)線離燈光過近。
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.
在使用會議室音響系統(tǒng)的時候，如果稍有不注意就有可能發(fā)生音頻干擾的現(xiàn)象，所以，即便使用的是質(zhì)量很好會議室音響系統(tǒng)，但是在使用過程中仍然要注意一些事情，只要能夠避免設(shè)備之間的干擾、電源干擾以及燈光干擾，那么就能有效避免出現(xiàn)各種干擾噪音。關(guān)注我們，了解關(guān)于音響

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.
