The conference room audio system is a standing equipment in the conference room, but many conference room audio systems will have audio interference during use, which has a great impact on the use of the audio system. Therefore, the cause of audio interference should be actively identified and solved. Today Lingjie will share with you how to avoid audio interference with the conference room sound system.

If the power supply of the conference room audio system has problems such as poor grounding, poor ground contact between equipment, impedance mismatch, unpurified power supply, audio line and AC line in the same pipe, in the same trench or in the same bridge, etc., the audio frequency will be affected. The signal creates clutter, creating a low-frequency hum. In order to avoid the audio interference caused by the power supply and effectively solve the above problems, there are the following two methods.

1. Avoid devices interfering with each other

Howling is a common interference phenomenon in conference room audio systems. It 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 is pointed at the speaker. At this time, the empty sound will be caused by the sound wave delay, and screaming will occur. When using the device, pay attention to pulling the device away to effectively avoid audio interference caused by mutual interference between the devices.

2. Avoid light interference

If the venue uses ballasts to start the lights intermittently, the lights will generate high-frequency radiation, and through the microphone and its leads, there will be a “da-da” audio interference sound. In addition, the microphone line will be too close to the light line. Interference sound will also occur, so it should be avoided. The microphone line of the conference room sound system is too close to the light.

When using a conference room sound system, audio interference can occur if care is not taken. Therefore, even if you use a first-class conference room audio system, you should pay attention to some things during use. As long as you can avoid interference between devices, power interference and lighting interference, you can effectively avoid all kinds of interference noise.

So the above is an introduction to the method of avoiding audio interference with the conference room sound system, I hope it will be beneficial to you~
