The noise of "å±å±å•¦å•¦" makes people feel very uncomfortable. Then, we can't help but ask, why is there noise in the audio equipment? 
Below we will introduce you to the four reasons for the noise in the audio equipment in the audio failure. 1. Noise generated by electromagnetic radiation Electromagnetic radiation causes stray electromagnetic wave radiation interference in the noise environment, such as high-frequency electromagnetic wave radiation interference from communication equipment such as mobile phones and walkie-talkies. The solution to the noise of the guests is to ask our staff to remind the guests not to bring their communication equipment close to our audio equipment while providing services to our guests. 2, the noise generated by the grounding loop In the audio system, the entire system must be required to have a good grounding, the grounding resistance requirements are less than 4 ohms. Otherwise, the inductive charge generated by the device in the lighting and sound rental system due to various radiation and electromagnetic induction will not flow into the earth, thereby forming a noise voltage superimposed on the audio signal. 3, the noise generated by power interference When our audio equipment is a problem, it is generally not at the time of the entire sound engineering design. If you want to avoid this phenomenon. When designing the lighting rental project, we tried to separate the power lines in our private rooms. 4. Noise generated inside the audio equipment If the quality of the audio equipment purchased by our KTV is not good, there are also some reasons for this. Therefore, we need to pay attention to the purchase of lighting and audio rental equipment, audio equipment has an indicator - signal to noise ratio. Everyone needs to pay attention to check this information when purchasing.
