When everything is settled, you will continue to make some fine-tuning in the future to meet your own requirements. If it is, every time you change new equipment and change the position, you should make some adjustments depending on the situation. In other words, the school sound and the sound are really inseparable, unless you don't know how to do it or don't pay much attention to it.
Beep rule Â
In order to improve the replay effect of a system, in addition to replacing more expensive and more awkward equipment, there are still many methods, and some even have no effect on pennies.
1. Fully clean the contacts once every six months
This program is often forgotten, but it is necessary to know that soon after the metal is exposed to the air, the surface will be oxidized, tarnished and dull. Even if the signal plug surface 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 channel causing poor contact, so it should be cleaned at least once every other year. 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.
2. Cleaning the CD player's laser cartridge
Everyone should have seen that the laser phono is only a small area, and it relies on laser light to read the marks on the CD. Therefore, as long as the little dust adhered to the phono is enough to affect the reading signal. The accuracy, although the CD machine has a sealed body, but don't forget that there is a gap in the process of often discs into the disc to let the dust take advantage of it. After a period of time, the surface of the cartridge will remain more or less. Dust, then you need to screw the cover screw, open the cover and use a cotton swab to wash the alcohol. Although there are various kinds of cleaning CDs on the market, you spend a few tens of dollars. The so-called CD-washing discs may only rely on a row of brushes to sweep off the dust or use the suede to turn the dust to remove dust. Do not use cotton swabs directly to the bottom. 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 return to the old days and the details will be heard.
3. Wipe your feet with sand glue
Friends who use the amplifier in the home can go to the bookstore to buy a sandpaper pen and gently rub each gallbladder's feet, then put it back into the gallbladder. The lamp that has been wiped by this will indeed squeak a little, and the frequency bands will be heard. There are improvements, and the amount of information is more. This method was taught by a teacher who passed the welding machine many years ago. I remember that he also said that when the hand sweats for a long time, it is not appropriate to go directly to the magnetic body, so as to avoid leaving sweat to hinder the heat dissipation of the lamp, preferably when contacting the gallbladder. It is best across the towel.
4. Place equipment to avoid machine stacking
It is also helpless to stack the equipment on the basis of environmental problems. When conditions permit, the most important CD sources and sound reinforcements should be placed independently. The main damages are mainly caused by Caused by the harmonic shock. 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. This is to place the equipment on a stable rack.
5. The best distance between the split power supply and the host and 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 put 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. The audio and video will be more accurate! The rear stage of the mono is also the same. It is conditional that the equipment is placed a little apart for two years to ensure that it is beneficial.
6. Pay attention to the connection of speaker cable and equipment
Bare wire connection is of course the best, but it is easy to oxidize, and tin can solve the problem. When the core is thick, you need to use the fork or banana to insert these two commonly used connecting media. If you can, you can definitely use the fork. Because the contact is not as easy as the banana plug, it is easy to pull off. On top of it, add a banana plug to connect the horn or the megaphone. The sound of one plug is obviously much worse. Regularly check if the fork and the joint are not connected firmly. When selecting the fork and banana, pay attention to the high copper content will be softer, non-use of banana can not be inserted, it should be inserted into the bulging, because the contact area will be larger.
7. Abolish the adjustable volume output of the CD player
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 in front of the fuselage. The headphone output device can also be abolished when it is not needed. The two sets of signal outputs are separated by the main signal. Once abolished, only one set of fixed volume output is used without thinning the signal output. Energy, 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.
8. Those who have a connection bridge behind the merger machine are also required to change
Some combined amplifiers can be used independently as front and rear stages. There is a U-shaped metal strip connecting the pre-out and mainin in the north of the fuselage. Although it is only the length of the three-inch inch, it can be regarded as the front-end wiring. The change of the line will definitely improve, but the finished line sold in the market is more than one meter long, so you can buy the bulk line to create the shortest connection line yourself. The material only needs four RCAs to connect the same length of signal. The line is opened two, that is, one half foot length. Due to the short distance, the outer and negative parts of the signal line can be omitted. Only a thin strip of the underarm positive electrode is left. The solder is soldered on the RCA and you are done. Since only one foot line is used, buy a little bit. The squall line is also expensive, but the effect can be changed from the ordinary line to the humming signal line. Home Theater Network welcomes you!
9. Steady power cord board
At present, the price of the equipment must use five ampere or thirteen ampere plugs. When connected with the carriage, the tightness is much higher. It will not be easily shaken by touching it. In contrast, the American three-legged or ordinary flat two are still used. If the foot is inserted, it will inevitably be swayed when the board is inserted, and it will help to squeak the sound with the board. The method is to tie the power plug on the carriage with a young rope or wire, and then connect a large board or cloud with a double-sided adhesive tape or rope under the carriage to further strengthen the stability, and the sound is naturally improved. It will make the audio and video clearer and the lines more subtle.
10. The less the interference, the louder the sound
Indoor audio-visual equipment and computers should avoid sharing a set of power supplies with the audio, but they should be put together by other places to take power. Secondly, the wiring will be entangled and the lines and lines will absorb noise. Destroy the sound quality. If you want to further achieve the pure effect, you can make the wire off the ground, just use the chess or clothespin to take up the wire body, but it may make the sound too clean, depending on the situation, it can be regarded as a kind of school sound. It is not necessarily suitable.
11. Equipment needs to be kept
Not only the equipment, but also the wiring is the same as Baoshun. It is recommended that you buy an XLO burn-inCD and use the track8's security signal to protect the equipment. The signal contains extremely high to very low frequencies, which can be used to save twice the effort.
Every new equipment or wiring can be bought back through the maintenance procedure, and it can enter the stable and squeaking state more quickly. Even if the equipment has been used for a period of time, it can be guaranteed. As long as it is not mature, I believe it is still Staying improved, especially the speaker effect is particularly good, continuous training for ten hours has been seen.
In order to protect the equipment, there is also the advantage of making the connection part of the complete system run smoothly. The situation is like the continuous signal of the system and the system of the system. The sound has become smooth, the high frequency of the hard corners, the corners have been modified, it sounds much more comfortable, the singer seems to sing more and more input, and the low frequency is also calm, this is not just a dish of credit, Rather, each part of the connected paragraphs and equipment has entered a better state. This disc is just a role assisted by the side guide.
12. Horn placement
It is a very important part of the school sound after the placement. It is not sloppy, and it is inevitable that the replay effect will be greatly reduced. How to find the best position in the room is really a test of time, may wish to read the "Fever Audio" March 1995 Horn speaker special edition, the content is detailed, you can fully understand your doubts.
13. Dim environment helps to hear the effect
It is a habit to close the class to listen to songs. It can be said that it is not related to replay, but in the dark environment, the ears will be particularly sensitive, and the visual obstacles will be reduced, and the sound picture reorganization and musical instruments will be The sense of position will be particularly clear and clear. The good atmosphere is far from the light when you turn on the lights. If you are afraid of black and white, you can put a flashlight for lighting.
Other snoring
In addition to the above, there are vocal tricks such as sound absorption, nailing, wiring and accessories.
Sound absorption
In the general family environment, furniture and debris are already good sound-absorbing materials, so it is not necessary to stir the sound-absorbing effort too much. Generally, a carpet has a basic sound-absorbing effect. The added benefit of the 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 covered with felt, and it is known to test the sound on the floor. The carpet is almost the same, so it is not afraid that once the carpet is bought back, it will not be used.
When the speaker is too close to the back wall, you can also consider adding a hanging felt to increase the depth and width, but be careful not to use too large blocks, otherwise you may even suck the UHF, unless your combination is being high frequency. Too much glory and trouble, for the excessive high frequency can also lick a BlueTak, attached to the tweeter's tweeter, the sharp voice will converge a little. In addition, the glass and mirror of the room will have a strong reflection sound, and it is necessary to use a window to cover 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 appropriate amount of reflection sound is to help the sound lively.
Studded foot
There are wooden nails, metal nails, ceramic nails, crystal nails, diamond nails, mixed nails, etc. on the market, only because the harmonic performance of each material is different, and the equipment will come with different materials. The sound characteristics of the substance, each of which has its own unique harmonic shock, is reflected in the replay of wood with wood sound, metal with metal sound, glass with glass sound, whether it is the rack, nails of the equipment The foot or the object used to press the fuselage will preach its own voice to the equipment. In general, the sound of the coffin is always more popular in line with the principle of fax hum, and its harmonic shock makes the replay sound more Since the iron rice bowl is pleasing to the ear, most of the nailing is made of wood, and it is equipped with harder materials such as copper, steel, crystal, diamond, etc. as the nail tip to achieve further effects.
It can be said that the use of nails is a lesson that is more compulsory. It should be helpful to the sound field, image, air, line, depth, dynamic, low-frequency bounce, etc. When put in the book back, the nail foot also comes in handy. The principle of repeating the nailing foot here is to change the sound of the equipment due to the reduction of the harmonic vibration. As long as you master the relationship between the harmonic shock and the replay sound, it is the skill of the school sound.
Wiring
Among the combinations of humming sounds, the importance of wiring is an indisputable fact. I think it is not an exaggeration to raise it to the same level as the equipment. In the end, at least several different connections are applied to the system, each of which has A certain degree of influence, the power of change that can be added up in a large amount can be very large, so when it is appropriate, it will be effective and effective, and even worse, it will be heard. I would like to emphasize that the power cord of each equipment must also be taken into consideration. Even if the design cannot be separated from the fuselage, it can be cut off a few inches, and then connected to the power cord for the plug. Yes, only a few inches to ensure that the effect and the original plug difference is not big, want to save money with the speaker cable to modify it.
annex
There are more and more audio accessories in the world, and there are many innumerable sums. Some of them are very theoretical, and some are very strange. Actually, the actual results are really trying to be true and false. When there is a chance, some will be Effective audio accessories are recorded and assembled into articles for sharing with readers.
postscript
In the process of school sound, it is best to remember how much improvement each program has, and if it is worse than before, it may be impossible to implement it, or this method is not suitable for your existing system. For example, adding nails, shock absorbers, using team parts, etc., need to be applied just right, just enough, otherwise it will be too late, I hope that readers will gain valuable experience after trying more, and when they encounter problems, they will know the right medicine.
