Clean the contacts every six months

Shortly after the metal is exposed to air, the surface layer will oxidize. Even if the surface of the signal wire plug is gold-plated and in close contact with the fuselage plug, it will still be oxidized to a certain extent and cause poor contact after a long time, so it should be cleaned every six months at most. Just use cotton dipped in alcohol to smear the contacts. After doing this heavy work, the contacts can be restored to the best contact, and the sound will also be better.

Avoid stacking machines as much as possible

The most important CD signal source and amplifier part should be placed independently as much as possible, because overlapping placement will cause resonance and affect the machine. When the speakers are playing music, the vibration of the air causes the equipment to vibrate, and the two devices overlap each other and resonate with each other, which makes the music lack of subtle information and interferes with the transmission of various frequency bands, causing a kind of sound pollution. The main part is a CD player. When the disc is played by itself, the continuous rotation of the motor increases the resonance amplitude, and the impact is even greater. Therefore, the equipment should be placed independently on a stable rack.

The less interference, the better the sound

Household appliances and computers in the room should avoid sharing a power source with the speaker, and even if they are to be placed together, they should obtain power from elsewhere. Secondly, tangling the wires together will also cause the wires to absorb noise from each other and destroy the sound quality. Both equipment and cables should be kept free of interference from other electrical appliances or power cords.

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 if the placement is not good. How to find the best placement position in the room is quite a test. In addition to listening carefully to the effects of different placement positions, you can also ask relevant experts to give guidance.

Dim environment can help listening effect

Listening to music with the lights off is a habitual problem. It can be said that it has nothing to do with playback, but in a dark environment, the ears will be particularly sensitive, and the visual obstacles will be reduced. It will feel very clear and clear, and the atmosphere is far from the best when the lights are turned on. You can also use some other dim lights to create a listening atmosphere.

proper sound absorption

In a general family environment, the furniture and sundries are already good, so there is no need to make the sound absorption too complicated, and laying a carpet can basically enhance the sound absorption effect. The advantage of adding carpet is to reduce the reflection of the floor and avoid mixing the sound coming from the front. When the speaker is too close to the rear wall, you can also consider adding a tapestry to increase the sound absorption effect, but be careful not to use too large a block, otherwise it may absorb even the ultra-high frequency. In addition, the glass and mirrors in the room will have a strong effect of reflecting sound, and curtains need to be used to block the problem to solve the problem. Friends with high requirements may wish to do more sound absorption at the corners of the wall and indoor sound reflection points, but pay attention to the sound absorption not too much. The right amount of reflected sound will help the sound to be lively and lively.
