[Home Theater Network HDAV.com.cn] Many people will have concerns when using the audio, how to maintain our audio, in order to extend its life and sound quality to the extreme? Clean once every six months When the metal is exposed to the air, the surface layer is easily oxidized. Even if the surface of the signal cable plug is gold-plated, it has close contact with the body plug. 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 contacts. After doing this heavy work, you can restore the contact to the best contact, and the sound will be clear and transparent. Avoid stacking Overlapping placement can cause harmonic shocks and affect the machine, so try to place the main CD source and the amplified part separately. When the horn plays music, the vibration of the air causes the equipment to follow the vibration. When the two machines are stacked, they will resonate with each other, making the subtle messages in the music obscure, and interfering with the transmission of each frequency band, causing a 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. Use a separate power supply 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. Placement position 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. Use environment Experienced big coffee said that the dim environment helps to hear the effect. Turning off the lights and listening to music is a matter of habit. In the dark environment, the ears will be particularly sensitive, and the visual obstacles will be reduced. The reorganization of the sound picture and the position of the instrument will be particularly clear and clear. Good and farther away when lighting up, you can also use some other darker lighting to create a listening atmosphere. Appropriate sound absorption In the general family environment, the furniture and debris are already good sound-absorbing materials, so it is not necessary to make the sound absorption too complicated. The carpet has a basic sound absorption effect. The added benefit of the carpet is that it reduces the reflection of the floor and avoids the turbidity caused by the sound from the front. 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 corner position 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. Up posture The processing of the sound field environment is actually how to do the acoustic design of the listening room, to follow the following principles: 1. Choose the appropriate proportion of the room, or make the walls not parallel, or increase the spread, to avoid or mitigate the effects of standing waves. 2. The reverberation time is appropriate to make the critical distance as far as possible. 3. Absorb a reflection sound to reduce the interference of a reflected sound on the direct sound. 4, try to absorb sound, if you can not make the sound absorption meet the requirements, try to spread the reflected sound, so that the sound field is as uniform as possible.
