As we all know, whether in large-scale conference activities or in the daily life KTV rooms singing, will encounter the sound system noise problems, "squeaky" noise is very uncomfortable listening to people. So, we can not help but ask, why the sound equipment noise? Here we will tell you about the sound of audio equipment in the noise of the four reasons.

1, electromagnetic radiation caused by the noise

Electromagnetic radiation caused by the noise environment of the stray electromagnetic radiation interference, such as mobile phones, walkie - talkie and other communications equipment, high - frequency electromagnetic radiation interference, and so on. In order to make the guests comfortable singing this noise solution is to ask our employees to provide services for the guests when euphemistically reminded guests not to their own communications equipment close to our audio equipment.

2, the noise generated by the ground loop

In the sound system, the system must be required to have a good grounding, grounding resistance requirements of less than 4 ohms. Otherwise, the lighting charge system in the equipment due to a variety of radiation and electromagnetic induction generated by the induced charge will not be able to flow into the earth, resulting in noise voltage superimposed in the audio signal.

3, the power generated by the interference noise

When our audio equipment is a problem, we are generally in the sound engineering design is not up to standard. If you want to avoid this phenomenon. We in the lighting audio leasing engineering design as far as possible in our private rooms in the power lines separately designed.

4, the sound generated inside the audio equipment

If we KTV to buy audio equipment quality is not good, this is the cause of some. So we buy lighting audio rental equipment when you need to pay attention to the audio equipment has an indicator - signal to noise ratio. Everyone in the purchase of the time need to pay attention to view this information.
