How to solve the problem of unclear sound quality of sound aging?

For the sound, the sound quality is also very important, because the lack of real natural texture, it will lose the most real quality! So today, Xiao Tuo came to share with you nine ways to make the sound quality more beautiful. Interested friends should pay attention to it!

　　Method one: every six months a comprehensive cleaning contact

As we all know, metal exposed to the air soon, the surface will be oxidized, lose luster, become dull. Even if the surface of the signal line plug is not easy to oxidize after gold plating and is in close contact with the body plug, there will still be a certain degree of oxidation leading to poor contact over time, so it should be cleaned at most every six months. As long as the contact is smeared with cotton and alcohol, after this heavy work, the contact can be restored to the best contact, and the sound will be clearer and more transparent.

　　Method two: cleaning CD player laser head

Obviously, the laser head has only a small area, but it all depends on it to read the marks on the CD disc, so only a few dust attached to the head is enough to affect the accuracy of reading the signal. Although most CD players have sealed bodies, don't forget that there are gaps for dust to take advantage of in the process of frequent disc entry. After a period of time, there must be more or less dust on the surface of the singing head. At this moment, it is necessary to unscrew the cover screw, open the cover and directly clean it with cotton swabs and point alcohol. Although there are all kinds of cleaning CD discs on the market, you have spent tens of dollars. Those so-called cleaning CD discs may only rely on a row of brushes to remove dust or use suede and other methods to remove dust by rotation. The effect is not as thorough as using cotton swabs directly. When your CD player, which has not been washed for a long time, is cleaned, it will make people feel like lifting a layer of yarn when listening again, while the high frequency will restore the clarity of the old days and the details will be much more beautiful. This step of cleaning the singing head will be done about once a year. Even if the Pioneer reverse turntable system is used (the laser head is down instead of up), dust will still be attracted by the static electricity brought by the singing head and adhere to it, so this time cannot be saved.

　　Method 3: Try to avoid machine stacking

Due to environmental problems, there is no choice but to stack the equipment. When conditions permit, the most important CD source and amplification parts should be placed independently as far as possible, because overlapping placement will cause harmonic vibration and affect the machine. When the loudspeaker plays music, the vibrating air causes the equipment to follow the vibration, and the two machines will spread the harmonic vibration to each other when stacked, which makes the fine information in the music blurred and interferes with the transmission of each frequency band, causing a kind of sound pollution. For example, one of them is a CD player, and the continuous rotation of the motor when playing the disc itself intensifies the harmonic vibration amplitude and has a greater impact. Therefore, the equipment should be placed on a stable rack independently.

Method 4: Keep the distance between the split power supply and the host and the mono rear stage

At present, even many mid-price front-level units have a box-sized split power supply, which simply separates the fire cow from the main engine into two parts. Naturally, the advantage is that the interference that may be caused between the internal parts of the machine and the fire cow can be isolated. If the split power supply is placed next to the front stage, it is a bit meaningless. Move it away from the front stage as soon as possible. If it is placed on a rack on another floor, the overall isolation can be heard in real time and the audio and video will be more accurate. The same is true for the rear stage of mono, and the conditional two pieces of equipment are placed separately to ensure that they are beneficial and harmless.

　　Method five: Abolish CD player adjustable volume output

Many single CD players are equipped with adjustable volume output so as to control the volume by remote controller. If you don't need this adjustable output, you can scrap it. Even the earphone output device in front of the body can be abolished together if you don't need it. These two sets of signal outputs are separated by the main signal. Once abolished, when only one set of fixed volume output is used, the energy of the signal output will not be thinned out. The sound will be cleaner and the sense of force will be better than before. It is not complicated to abolish these two sets of output methods, as long as the cover is opened and the relevant connecting wires in the machine are drawn up.

　　Method six: interference less sound more beautiful

Indoor household appliances and computers should avoid sharing a set of power with the audio, even if they are put together, they should get power from elsewhere. Secondly, entangling the wiring will also cause the line to absorb noise from each other and destroy the sound quality. Whether it is equipment or connecting wires, it should be kept free from interference from other electrical appliances or power cords.

　　Method seven: horn position

The placement of speakers is an important part of the use of sound, and poor placement will inevitably reduce the playback effect. How to find the best placement in the room is quite a test. In addition to listening carefully to the effects of different placement positions, you can also ask relevant experts for guidance.

　　Method 8: Dim environment helps listening effect

It is a customary problem to turn off the lights to listen to music. It can be said that it has nothing to do with playback. Only in a dark environment, the ears will be especially sensitive, and the visual obstacles will be reduced. The sound picture reorganization and the position sense of the musical instruments will be especially clear and clear. The good atmosphere is far away from the bright lights. Other dim lights can also be used to create a listening atmosphere.

　　Method 9: sound absorption

In the general family environment, furniture and sundries are already good sound-absorbing materials, so there is no need to make the sound absorption too complicated. Laying a carpet already has a basic sound-absorbing effect. The advantage of adding carpet is that it can reduce the reflection sound of the floor and avoid mixing with the sound from the front. I want to know whether I need to add carpet to my room and test the sound on the ground. When the horn is too close to the back wall, you can also consider adding a tapestry to increase the sound absorption effect, but you should pay attention to not using too large a piece, otherwise you may even suck off the ultra-high frequency. In addition, the glass and mirror of the room will have a strong reflection sound effect, need to use curtains to block to solve the problem. Friends with high requirements may as well do more sound absorption in the corners of the wall and the sound reflection points in the room, but they should pay attention to the sound absorption not too much. A proper amount of reflected sound is helpful for the sound to be vigorous and lively.
