What are the taboos of using at audio?

With the popularity of audio-visual equipment, more and more people are interested in the field of audio-visual. As an enthusiast, it is important to have a set of high-end equipment, but the correct use of these equipment is equally important. In the general audio enthusiasts, there are some errors in the use should be avoided.

First, put the equipment in the cabinet. Some people put the equipment into the customized cabinet for decoration and protection, which will cause the latent vibration caused by the cabinet space to make the tone turbid, power amplifier and other equipment because there is not enough air flow, easy to overheat and aging. If the speaker is loaded into the wall, the sound effect will become stiff.

The second is stacking equipment. Many people like to overlap DVD player, amplifier, tuner, digital analog converter and other machines, which will cause mutual interference, especially serious interference between the laser camera and the power amplifier, which will make the timbre harder and produce a sense of depression. The right thing to do is to put the equipment on the speaker rack designed by the manufacturer.

Third, the power plug is positive and negative. The system with good positive and negative processing of power plug has clear timbre hierarchy and natural smoothness; the timbre will be hard and rough if the positive and negative are inconsistent or uneven.

Fourth, the connection is not firm and unclean. If the system timbre is dry, one of the reasons may be poor contact, such as plugs are not strong, contact surface oxidation, dust or oil stain, so it should be checked regularly to keep the contact surface clean.

Fifthly, it is used as loading equipment of dolomite or glass. Low density and high resonance of dolomite will affect the sound effect. Glass density is higher than that of dolomite, but it is not thick and resonant more seriously. Granite or flagstone can be used, especially flagstone, with the highest density and ideal load-bearing equipment, but with a thickness of more than 3 centimeters.

Sixth, the placement of speakers should be "tailored to local conditions". Some people have other furniture in the room first, and put the speaker in the place of furniture. The correct listening distance should be determined first, and then the speaker should be placed in 1/3 of the seats and the opposite wall. The distance between the speaker and the speaker is 0.7 times of the direct distance between the speaker and the speaker. The height of the speaker's ear and the high-pitch unit should be equal.






Seventh, improper handling of wiring. When dealing with wiring, we should not tie the power line with the signal line, because the AC will affect the signal; the signal line or the horn line can not be tied, otherwise it will affect the timbre; the signal line or the horn line can be shortened if it is too long. Many signal lines are directional. Don't make mistakes.






Eighth, take it for granted to deal with the sound effects of the room. In addition to the sound, sound insulation, and more importantly, the treatment of acoustic reflection and refraction, which requires consideration of the room's size, size, solidity, the use of materials, etc., such as not an expert, even if the room is decorated luxuriously beautiful, the sound is difficult to achieve the best effect.






Ninth, blindly imitate. Do not proceed from reality, blindly imitate others. If people use long signal lines and short horn lines, the effect is good. This is because the front and rear stages are balanced with the laser, and your equipment is not balanced. If you imitate it, it will be difficult to achieve the same effect.






Ten is self-deception. If the equipment plays a certain kind of concert very well, while playing another kind of music is not ideal, this shows that the system has not reached the desired level, and needs to learn, listen and observe more, and thus improve.
