Why Does KTV Sound Equipment Appear Noise?

- Jul 18, 2018-

1. Noise generated by power supply interference

Therefore, the audio equipment is generally not in compliance with the entire sound engineering design. In order to avoid this phenomenon, try to separate the power lines in the private room.

2. Noise caused by electromagnetic radiation

The high-frequency electromagnetic radiation of mobile phones, walkie-talkies and other communication equipment will also be the cause of noise. In order to let the guests sing comfortably, the way to solve this noise is to euphemistically remind the guests not to bring their communication equipment close to the audio equipment.

3. Noise generated by the ground loop

In an audio system, the entire system must be grounded properly and the grounding resistance is less than 4 ohms. Otherwise, the inductive charge generated by the acoustic device due to various radiation and electromagnetic induction will not flow into the ground, thereby forming a noise voltage superimposed on the audio signal.

4. Noise generated inside the audio equipment

If the quality of the audio equipment we purchased from KTV is not good, there are also some reasons for this. Therefore, we need to pay attention to when purchasing KTV audio equipment, audio equipment has an indicator - signal to noise ratio. Everyone must pay attention to check this information when purchasing, and buy a good quality brand audio.
