For the sound, the sound quality is also very important, because the lack of real and natural texture, it will lose the most authentic quality! So today, Xiaobian and everyone share the way to make the audio quality more ambiguous. Interested friends should pay attention!
One: comprehensive cleaning contact once every six months
Everyone knows that soon after the metal is exposed to the air, the surface will be oxidized, tarnished and dull. Even if the surface of the signal plug is gold-plated, it is not easy to oxidize and has close contact with the body plug. However, after a long time, there will still be some degree of oxidation leading to poor contact, so it should be cleaned at most once every six months. Just use cotton with alcohol to smear the joints. After doing this heavy work, you can make the contact respond to the best contact, and the sound will be clear and transparent.
Two: cleaning CD player laser cartridge
Obviously, the laser cartridge has only a small area, but it relies on it to read the marks on the CD. Therefore, as long as the tiny dust adheres to the cartridge, it is enough to affect the accuracy of the read signal. Although the CD player has a sealed body, but don't forget that there are gaps in the process of discs and discs, so that the dust will be taken in. After a while, the surface of the cartridge will have more or less dust. When you need to screw the cover screw, open the cover and use a cotton swab to wash the alcohol. Although there are all kinds of cleaning CDs on the market, you spend a few tens of dollars. Those so-called CD-washing discs may just rely on a row of brushes to sweep off the dust or use the suede to turn off the dust. The effect is not as straightforward. Use cotton swabs thoroughly. When your CD machine that hasn't been shampooed is cleaned, it will make you feel a layer of yarn when you listen, and the high frequency will be clear to the old days, and the details will be much more pleasant. This step of cleaning the cartridge is done once a year. Even with Pioneer's inverted disc system (the laser head is down instead of upward), the dust is still attracted by the static electricity carried by the cartridge, so it sticks to it. This time is still not saved.
Three: try to avoid machine stacking machine
It is impossible to stack the equipment based on environmental problems. When conditions permit, the most important CD sources and sound reinforcement parts should be placed as far as possible, because overlapping placement will cause harmonic shock and affect the machine. When the horn plays music, the vibrating air causes the equipment to follow the vibration. When the two machines are stacked, they will evangelize each other, making the fine information in the music obscure, and interfering with the transmission of each frequency band, causing a kind of sound pollution. Another example is the CD player. When the disc is rotated, the motor is even more powerful, and the impact is even greater. So place the equipment on a stable rack.
Four: Separate power supply and the distance between the host and the mono stage
Nowadays, many middle-priced predecessors have a box-sized split power supply, which simply separates the AC adapter from the main unit into two parts. The advantage is naturally to isolate the interference between the internal parts and the AC adapter. If you place the split power supply next to the front stage, it will be a little meaningless. Move it away from the front stage. If you put it on another rack, you can hear the overall isolation improved in real time. The audio and video will also be accurate. The rear stage of the mono is also the same, and the two pieces of equipment are placed separately to ensure that they are beneficial.
Five: abolish the CD machine adjustable volume output
Many single CD players have adjustable volume output to control the volume with the remote control. If you don't need this adjustable output, you can abandon it, even the headphone output on the front of the camera. The device can also be abolished if it is not needed. The two sets of signal output are separated by the main signal. Once abandoned, only a set of fixed volume output does not need to thin the energy output of the signal, the sound will be more solid and the force is better than before. To abolish these two sets of output methods is not complicated, just open the cover and pull up the relevant cable inside the machine.
Six: the less the interference, the louder the sound
Indoor household appliances and computers should avoid sharing a set of power supplies with the sound, even if they are put together, they should be taken from elsewhere. Secondly, entanglement of the wiring will also cause the line to absorb noise from each other to destroy the sound quality. Whether it is equipment or cables, it should be kept free from interference from other electrical appliances or power lines.
Seven: speaker placement
The placement of the speakers is an important part of the audio use, and it is inevitable that the playback effect will be greatly reduced. How to find the best placement in the room is quite a test, in addition to constantly listening to the effect of different placement positions, you can also ask the relevant experts to guide.
Eight: dim environment helps listen to the effect
Turning off the lights to listen to music is a matter of habit. It can be said that it is not related to playback. In the dark environment, the ears are particularly sensitive, and the visual obstacles are reduced. The sense of position will be particularly clear and clear, the atmosphere is better and farther away when lighting, and other darker lights can be used to create a listening atmosphere.
Nine: sound absorption
In the general family environment, furniture and debris are already good sound-absorbing materials, so it is not necessary to make the sound absorption too complicated. The carpet has already had a basic sound absorption effect. The advantage of adding a carpet is that it can reduce the reflection of the floor, avoid mixing the sound from the front and cause turbidity. I want to know if my room needs to be carpeted, and I will know if there is any change in the sound on the floor. When the speaker is too close to the back wall, you can also consider adding a tapestry to increase the sound absorption effect, but be careful not to use too large blocks, otherwise you may even suck the UHF. In addition, the glass and mirror of the room will have a strong reflection sound, and curtains need to be used to solve the problem. More demanding friends may wish to do more sound-absorbing work in the corners and indoor sound reflection points, but pay attention to the sound absorption can not be excessive, the right amount of reflection sound is to help the sound lively.
CCTV pole is a type of pole used to mount a closed circuit television camera for surveillance and monitoring purposes. These poles are typically made of durable materials, such as steel or aluminum, and are designed to withstand a variety of weather conditions.
