With the popularization of film and television audio equipment, more and more people are interested in the audiovisual field. As an audiophile, it is important to own a set of high-end equipment, but it is equally important to use these equipment for positive synchronous motors. For now, among general audio enthusiasts, there are some misunderstandings that should be avoided.
One is to put the equipment into the cabinet. Some people put the equipment into a custom-made cabinet for decoration and protection. This will make the sound turbid due to the latent vibration caused by the space in the cabinet. The power amplifier and other equipment are prone to overheating and aging because of insufficient circulating air. If the speaker is installed on the wall, the sound effect will become stiff.
The second is stacking equipment. Many people like to put DVD players, amplifiers, tuners, digital-to-analog converters, etc. on top of each other. This will cause mutual interference, especially the interference between the laser camera and the power amplifier, which will make the sound hard and suppressive. The correct approach is to place the equipment on the audio rack designed by the manufacturer.
The third is that the power plug is positive or negative. A good system for the positive and negative processing of the power plug has a clear tone and natural smoothness; the positive and negative are inconsistent or uneven, and the tone will be hard and rough.
Fourth, the wiring is not fast or clean. If the sound of the system is dry, one of the reasons may be poor contact, such as a weak plug, oxidation of the contact surface, dust or oil, etc., so it should be checked frequently to keep the contact surface clean.
Fifth, use marble or glass level gauge to carry equipment. The low density and high resonance of marble will affect the sound effect. The glass density is higher than marble, but it is not thick and the resonance is more serious. Granite or hemp stone can be used, especially hemp stone, which has the highest density and ideal carrying equipment, but the thickness is more than 3 cm.
Sixth, the placement of the speakers is "suitable to local conditions". Someone moved the furniture to place the speakers because there were other furniture in the room first. The correct listening distance should be determined first, and then the hazardous chemical tank speaker should be placed 1/3 of the distance between the seat and the opposite wall. The distance between the speakers is 0.7 times the direct distance between the listener and the speaker. Units are flush.
Seven is improper wiring. When handling wiring, do not tie the power cord and the signal cord together, because the AC power will affect the signal; neither the signal cord nor the speaker cord may be knotted, otherwise it will affect the sound; the signal cord or the speaker cord may be too short and can be changed. Many signal lines have directionality, don't get it wrong.
Eight is to take for granted the room acoustics. In addition to sound and sound insulation, the more important thing is the treatment of sound reflection and refraction. This needs to consider the room volume, size, ruggedness, and use of materials. best effect.
Nine is to follow blindly. Do not proceed from reality and blindly imitate others. For example, the long signal cable and short speaker cable in people's homes have good effects. This is because the front and rear stages and the laser are balanced, and your equipment is not balanced. If you imitate, it is difficult to achieve the same effect.
Ten is self-deception. If the equipment plays a certain type of concert, the effect is very good, but the other type of music is not ideal. This shows that the system has not reached the ideal level, and it needs to learn, listen, and observe more to improve it.
