As we all know, soon after the speaker metal is exposed to the air, the surface will be oxidized, lose luster and become dull. Even though the surface of the signal line plug is not easy to oxidize after gold plating and has close contact with the fuselage plug, over time, there will still be a certain degree of oxidation leading to poor contact, so it should be cleaned every six months at most. Just smear the contact with cotton stained with alcohol. After this heavy work, the contact can return to the best contact, and the sound will be clearer and more transparent.
Rule 2 cleaning CD player
Obviously, the laser cartridge has only a small area, but it can read the marks on the CD. Therefore, as long as a little dust is adhered to the cartridge, it is enough to affect the accuracy of reading the signal. Although most CD players have sealed bodies, don't forget that there are gaps in the process of often releasing and putting in discs, allowing dust to take advantage of it. Over a period of time, there must be more or less dust on the surface of the phonograph head. At this time, you should screw the boot cover screw, open the cover and directly use a cotton swab to point alcohol for cleaning. Although there are all kinds of CD cleaning on the market, you spent dozens of yuan. Those so-called CD cleaning may only * brush in a row to sweep away the dust, or use suede and other * rotation to remove the dust. The effect is not as thorough as directly using a cotton stick. When your CD player that hasn't washed your hair for a long time is cleaned, it will make you feel like lifting a layer of yarn when listening again, and the high frequency will return to the old clarity, and the details are much more beautiful. This step of cleaning the cartridge needs to be done about once a year. Even if you use pioneer's reverse disc system (the laser head is down rather than up), the dust will still be attracted by the static electricity carried by the cartridge, so this time can't be saved.
Rule 3 avoid stacking as much as possible
Due to environmental problems, there is no choice but to stack the equipment for placement. When conditions permit, try to place the main CD source and loudspeaker independently, because overlapping placement will lead to harmonic vibration and affect the machine. When the loudspeaker plays music, the vibrating air causes the equipment to follow and vibrate. When the two machines overlap, they will preach harmonic vibration to each other, so that the fine information in the music is blurred, and interfere with the transmission of various frequency bands, resulting in a kind of sound pollution. Another example is that one of them is a CD player. The continuous rotation of the motor when playing its own disc intensifies the amplitude of harmonic vibration, which has a greater impact. Therefore, the equipment should be placed independently on a stable rack.
Rule 4 keep the distance between the split power supply and the host and the rear stage of mono
Nowadays, even many medium price front stages have a box size split power supply, which simply divides the fire cow and the main engine into two parts. The advantage is that it can isolate the possible interference between the parts in the machine and the fire cow. If the split power supply is placed next to the front stage, it will be a little meaningless. Quickly move it away from the front stage. For example, if it is placed in the rack on another floor, the overall spacing 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. If possible, the two pieces of equipment shall be placed separately to ensure that they are beneficial and harmless.
Rule 5 abolish CD player adjustable volume output
Many single CD players are equipped with adjustable volume output terminals to facilitate the remote control to control the volume. If you don't need this adjustable output, you can discard it. Even the headphone output device in front of the body can be abolished 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, there is no need to thin the energy of the signal output. The sound will be more solid and clean, and the sense of force will be better than before. To abolish these two groups of outputs, the method is not complicated. Just open the machine cover and pull up the relevant connecting wires in the machine.
Rule 6 the less interference, the better the sound
Indoor household appliances and computers should avoid sharing a set of power supply with the audio. Even if they are to be placed together, they should obtain power from elsewhere.
Secondly, entanglement of wires will also make lines absorb noise and destroy sound quality. Both equipment and connecting wires should be kept free from interference from other electrical appliances or power lines.
Rule 7 horn placement
The placement of speakers is an important link in the use of sound. If they are not placed well, it will inevitably greatly reduce the playback effect. How to find the best placement in the room is quite challenging. In addition to constantly listening to the effects of different placement positions, you can also ask relevant experts for guidance.
Rule 8 dark environments help you listen
Turning off the lights to listen to music is a habit problem. It can be said that it has nothing to do with playback. Only in a dark environment, the ears will be particularly sensitive, and the visual obstacles will be reduced. The reorganization of sound pictures and the position of musical instruments will be particularly clear and clear. The good atmosphere is far from that when the lights are on, You can also use some other dim lights to create a listening atmosphere.
Rule 9 sound absorption
In the general family environment, furniture and sundries are already excellent sound-absorbing materials. There is no need to make the sound-absorbing too complicated. Laying a carpet has basically strengthened the sound-absorbing effect. The advantage of adding carpet is that it can reduce the reflected sound of the floor and avoid mixing with the sound from the front. If you want to know whether your room needs to be carpeted and test the sound on the ground, you will know the change. When the horn is too close to the rear wall, you can also consider adding a tapestry to increase the sound absorption effect, but pay attention not to use too large pieces, otherwise even UHF may be absorbed. In addition, the glass and mirror in the room will have a strong sound reflection effect, which needs to be covered with curtains to solve the problem. Friends with high requirements might as well do more sound absorption at the corner and indoor sound reflection points, but pay attention not to absorb too much. An appropriate amount of reflected sound is helpful to make the sound vigorous and lively.
