One, the equipment is put into the ark. Some people for decoration and protection, the equipment in the custom closet, latent vibration this will caused because of the space in the cabinet to make the sound muddy, amplifiers and other equipment because there is not enough air circulation, prone to overheating, aging. As the speaker into the wall, will make the sound effect becomes blunt.
Two, stacking equipment. Many people love the DVD player, tuner, amplifier, digital to analog converter machine overlapped, this will cause mutual interference, especially the radium camera with the power interference is serious, will cause the timbre is hard and sense of oppression. The correct approach is the equipment placed by the audio frame on factory design.
Three, the connection is not strong and unclean. If the system timbre is dry and hard, one of the reasons may be poor contact, such as plug is not firm, the contact surface oxidation, dust or oil stain, so should be inspected regularly, keep clean contact surface.
Four, the power plug is not divided into positive and negative. System power supply plug of positive and negative is handled well, the timbre distinct, natural and smooth; the positive and negative inconsistent or uneven, sound hard rough.
Five, marble or glass carrier equipment. Marble density low, resonant high, can affect the acoustics. Glass density is higher than the mica, but not thick, the resonance is more serious. The available granite or granite, especially granite, the highest density, the load bearing equipment is ideal, but the thickness of 3 centimeters of above.
Six, connection improper handling. Treatment of wiring may not the power line and the signal line tied together, because the alternating current can affect the signal; the signal line or speaker cable cannot tie a knot, otherwise it will affect the timbre; signal line or speaker cable is too long can change the short. Many signal lines are directional, not a mistake.
Seven, speakers placed "adjust measures to local conditions". Some people because of the indoor first with the other furniture, and placing the speakers position to compromise the furniture. The right should first decide to listen to the distance, and then the speakers placed in 1/3 loci and between the opposite wall, the distance is 0.7 times the speaker listener and speaker direct distance, the height to the hearer ear and tweeter flush as well.
Eight, assume the sound effect processing room. In addition to a clear sound, sound insulation, more important is the treatment of sonic reflection, refraction, it needs to consider the room volume, size, strong use of degree, material, such as not experts, even if the room is decorated luxurious appearance, sound is also difficult to achieve the best effect.
Nine, blindly follow. Not from reality, blind imitation of others. As people home long signal line, short horn line with good effect, this is because the anteroposterior and laser machines are balanced, and your device is not balanced, but also to imitate, it is difficult to achieve the same effect.
Ten, self deception. If the equipment play a kind of concert, the effect is very good, and play another kind of music is not ideal, and this shows that the system has not reached the ideal level, the need to learn more, listen more, and more observation, so as to improve.
