1, the electromagnetic radiation causes of noise
Electromagnetic radiation causes of stray electromagnetic radiation interference of the noise of the environment, such as mobile phones, walkie-talkies and other communications equipment of high frequency electromagnetic radiation interference, and so on. In order to make the guests comfortable singing this noise solution is required our employees to provide service for the guests in the euphemism remind guests don't communication equipment near our stereo equipment.
2, ground loop noise
In the sound system, must require the system to have a good grounding, grounding resistance less than 4 ohm. Otherwise, lighting sound lease equipment in the system due to various radiation and electromagnetic induction to generate induced charge will not be able to flow into the earth, and the forming voltage noise superposition in the audio signal.
3, the power of the noise interference
When our audio equipment is generally so problems is that we are in the whole sound engineering design is not up to standard. If you want to avoid the occurrence of this phenomenon. We lease engineering design in the light of time as far as possible to separate the power supply line in our room design.
4, audio equipment noise generated inside it
If we buy it KTV audio equipment quality is bad, the reason is also available. So we in the choose and buy when lighting audio lease equipment need to be aware of is the audio equipment has an indicator, such as signal-to-noise ratio. You need to pay attention to when the choose and buy to see this information.
