Top ten use of audio taboo

Top Ten Use Taboos for Audio With the popularity of video and audio equipment, more and more people are interested in the audiovisual field. As a fancier, it is important to have a set of high-end equipment, but it is equally important to use them properly. In general audio lovers, there are some misunderstandings that should be avoided.

One is to put the equipment in the cabinet. Some people put equipment into custom-made cabinets for decoration and protection. This can make the sound turbid due to the vibration caused by the space inside the cabinet. Equipment such as power amplifiers are prone to overheating and aging due to insufficient ventilation. If you put the speaker into the wall, it will make the sound effect harder.

The second is stacking equipment. Many people love to superimpose DVD players, amplifiers, tuners, digital-to-analog converters, and other devices. This can cause mutual interference. In particular, serious jamming between laser and amplifiers will make the tone harder and produce a sense of depression. The correct approach is to place the equipment on a stereo rack designed by the factory.

The third is whether the power plug is positive or negative. A good system with positive and negative power plugs has a clear timbre and is naturally smooth; if the positive and negative are inconsistent or uneven, the timbre will be hard and rough.

Fourth, the wiring is not strong and dirty. If the sound of the system sounds dry, one of the reasons may be poor contact, such as loose plug, oxidation on the contact surface, dust or oil, etc. Therefore, it should be checked frequently to keep the contact surface clean.

The fifth is using marble or glass bearing equipment. The low density and high resonance of marble will affect the sound effects. The density of glass is higher than that of marble, but it is not as thick and resonant as it is. Available granite or granite, especially granite, the highest density, carrying equipment is ideal, but the thickness of more than 3 cm.

Sixth, the placement of speakers is based on local conditions. Someone moved the furniture to the place where the speakers were placed due to other furniture in the room. The correct distance should be decided first, and then put the speaker to the 1/3 between the seat and the opposite wall. The distance between the speakers should be 0.7 times the distance between the listener and the speaker. The height should be equal to the level of the listener's ear and the tweeter. .

Seventh, improper wiring. When handling the wiring, do not tie the power cable to the signal cable because the AC signal will affect the signal; the signal cable or the speaker cable cannot tie the cable; otherwise it will affect the tone; if the signal cable or the speaker cable is too long, it can be shortened. Many signal lines have directionality. Do not make mistakes.

Eight is to take care of the room acoustics. In addition to bright sound and soundproofing, the sound wave reflection and refraction treatment is more important. This needs to consider the size, size, firmness of the room, and the use of materials. If it is not an expert, even if the decoration of the room is luxurious and beautiful, the sound is difficult to achieve. best effect.

Nine is blindly emulated. Do not start from reality and imitate others blindly. For example, people's home long signal cables and short speaker cables are effective. This is because their front and rear stages and laser machines are all balanced, and your equipment is not balanced. It is difficult to achieve the same effect by mimicking them.

Ten are deceiving themselves. For example, if a device plays a certain type of concert, it works well, but playing another type of music is not ideal. This shows that the system has not yet reached the desired level. It requires more studies, more listening, and more observations, so that it can be improved.
