How to distinguish the quality of professional audio.Learning audio wholesale

　　There are many professional audio equipment on the market today, and the prices are similar, so how to distinguish the sound quality from the professional audio equipment here? Let Jazz Dragon tell you:

　　1. Whether the sound box has resonance

　　Resonance is actually a physical vibration phenomenon. When a resonance phenomenon occurs in the outer box of the audio equipment, the output sound quality of the audio equipment will be affected, which may make the sound of the audio equipment heavy and noisy. Therefore, it is recommended that you use wood as much as possible when choosing audio equipment cabinets. The cabinets made of this material are much more stable than plastic casings, and the probability of resonance will be reduced accordingly.

　　Of course, in addition to the material of the box, people's abnormal use and operation will also cause the box to resonate, such as the volume setting of the audio equipment exceeds the rated range.

　　2. Is the sound box well sealed?

　　The airtightness of the audio box will also affect the sound quality. In general, the better the airtightness of the audio box, the better the sound quality of the sound output by the audio equipment. So how do users check the airtightness of the audio box? It's actually very simple. As long as you put your hand outside the guide hole of the audio to feel it, if there is a relatively obvious phenomenon of air in and out, it can prove that the airtightness of the audio box is good.

　　3. Whether the audio box is anti-magnetic

　　Audio equipment is a relatively sophisticated instrument. It has high requirements for the surrounding environment during use, especially it is very sensitive to the surrounding magnetic field. Therefore, the audio box must have good anti-magnetic properties, otherwise there will be a magnetic field around. The fluctuation will make the output sound quality of the audio equipment worse.

　　In addition to the anti-magnetic type, the placement of the audio box during use is also very important. Keep all devices at a certain distance in a limited space as much as possible, and the two devices should not be too close to avoid Due to different magnetic fields, the use effect is affected by each other.
