Everyone knows that soon after the speaker metal is exposed to the air, the surface layer will be oxidized, lose luster and become dull. Even after the surface of the signal cable plug has been plated with gold, it is not easy to oxidize, and it is in close contact with the body plug. However, as time passes, there will still be a certain degree of oxidation leading to poor contact. Therefore, it should be cleaned at least once every six months. Just touch the cotton with alcohol to smear the contacts. After the heavy work is done, the contact can be restored to the best contact, and the sound will be clear and transparent.
Rule 2 Cleaning CD Laser Head
Obviously, the laser pickup has only a small area, but it reads the marks on the CD. Therefore, only a tiny amount of dust adhered to the pickup can affect the accuracy of the read signal. Although the CD players have sealed bodies, don't forget that there are gaps in the process of dishing out the dishes to allow dust to come in. After a few days, the surface of the pickup must have more or less dust. When you want to screw the boot cover screw, open the cover directly with a cotton swab to clean it with alcohol. Although there are all kinds of CDs on the market, you have spent tens of dollars. The so-called CD washing may be just a row of brushes to sweep away dust or use a suede or the like to rotate and dust. Use cotton swabs thoroughly. When your unwashed CD player is cleaned, it will give you a feeling of lifting a layer of yarn when you hear it, and the high frequency will restore the clarity of the old days, and the details will be much better. This step of cleaning the cartridge is almost done once a year. Even if Pioneer's reversing disc system is used (laser head down but not up), the dust will still be attracted by the static electricity carried by the cartridge, so This time can't be saved.
Rule 3 Try to avoid stacking machines
Based on the environmental issues, it is necessary to stack the devices and put them in a position where they can't help. When conditions are right, they should try to place the main sources of CDs and loudspeakers independently, because overlapping placements can cause resonance and affect the machine. When the speakers play music, the vibration of the air causes the equipment to follow the vibrations. When the two machines overlap each other, they will propagate each other's resonance, making the fine information in the music unclear and interfere with the transmission of each frequency band, causing a kind of sound pollution. And if one of them is a CD player, the motor rotation will exacerbate the magnitude of resonance when the player plays the disc itself, and the impact will be even greater. Therefore, the equipment must be placed on top of a stable rack.
Rule 4 Split Power Supply Keeps Distance Between Host and Mono Stage
Even many mid-price predecessors now have a box-sized split-type power supply, which simply separates the bull and the host into two parts. The benefit is naturally to isolate the interference between the internal parts of the car and the fire cow. If you place the split power supply unit next to the front stage, it would be a bit lost. Take it away from the front stage quickly. If you put it on another level of rack, you can hear that the whole room has been improved in real time. The audio and video will be accurate. The same applies to the monosound stage. The conditional two pieces of equipment are placed separately and ensure that they are harmless.
Rule 5 abolishing the CD volume adjustable output
Many single CD players are equipped with an adjustable volume output so that the volume can be controlled using the remote control. If you do not need this adjustable output, you can use it to eliminate it, even the headphone output in front of the camera body. Devices can also be abolished when they are not needed. The two sets of signal output are separated by the main signal. Once it is repealed, only one set of fixed volume output will not be used to divide the energy of the signal output. The sound will be more pure and better than before. To abolish the two groups of output methods is not complicated, just open the lid and pull up the relevant connecting lines inside the machine.
Rule 6 The less interference, the less noise
Household appliances and computers in the room should avoid sharing a set of power supplies with the audio. Even if they are put together, they should be powered from elsewhere.
Secondly, entangling the wires together can also cause lines and lines to absorb noise and destroy sound quality. Whether it is equipment or cables, it should remain undisturbed by other appliances or power cords.
Rule 7 Speaker Position
Placing the horn is an important part of the use of the audio system. How to find the best place to place in the room is quite an exam. In addition to constantly listening to the effects of different placements, you can also ask relevant experts to guide you.
Rule 8 Dirty Environment Helps Listening
Turning off the lights to listen to music is a matter of habit. It can be said that it is not related to playback. It is only in the dark environment that the ears are particularly sensitive and visual obstacles are reduced. The sense of location will be particularly clear and clear, the atmosphere is better than when you turn on the lights, you can also use other relatively dark lights to create a listening atmosphere.
