會(huì )議室音響系統是會(huì )議室應該配備的一種設備，但是很多會(huì )議室音響系統在使用過(guò)程中會(huì )出現音頻干擾，對音響系統的使用影響很大，所以我們應該主動(dòng)找出造成音頻干擾的原因，定位并解決。下面廠(chǎng)家告訴你會(huì )議室音響系統如何避免音頻干擾。
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.
如果會(huì )議室音響系統出現電源接地不良、設備間地線(xiàn)接觸不良、阻抗不匹配、電源未經(jīng)“凈化”處理、音頻線(xiàn)與交流線(xiàn)在同一管道、同一溝槽或在同一個(gè)電橋等處都會(huì )對音頻信號產(chǎn)生雜波干擾，形成低頻交流“嗡嗡”聲。為了避免電源造成的音頻干擾，應確保這些問(wèn)題能夠得到有效解決。
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.
避免設備之間的干擾。“嘯叫”是會(huì )議室音響系統中常見(jiàn)的干擾現象。它主要是由揚聲器和麥克風(fēng)之間的正反饋引起的。原因是麥克風(fēng)離揚聲器太近，或者麥克風(fēng)指向揚聲器。聲波延遲會(huì )產(chǎn)生“空聲”，并會(huì )出現“嘯叫”。使用時(shí)注意設備相互遠離，可以有效避免設備相互干擾造成的音頻干擾。
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.
避免光線(xiàn)干擾。如果在場(chǎng)館內間歇性使用鎮流器型照明燈，激發(fā)燈時(shí)會(huì )產(chǎn)生高頻輻射，將麥克風(fēng)與其引線(xiàn)串聯(lián)，產(chǎn)生“噠噠”的音頻干擾聲。太近也會(huì )造成干擾，所以應避免會(huì )議室音響系統的麥克風(fēng)線(xiàn)太靠近燈光。
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
山東會(huì )議室音響系統時(shí)，如果不小心，可能會(huì )出現音頻干擾。因此，即使您使用了高質(zhì)量的會(huì )議室音響系統，在使用過(guò)程中還是需要注意一些事項。只要能避免設備間的干擾、電源干擾、燈光干擾，那么各種干擾噪聲都能有效避免。
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.
