 With the popularity of film and television audio equipment, more and more people are interested in the audio-visual field. As an enthusiast, it is important to have a set of high-grade equipment, but it is also important to use them correctly. For the moment, there are some use mistakes that should be avoided in general audio lovers.

One is to put the equipment in the cabinet. Someone for decoration and protection equipment into a custom-made cabinets, which caused by rack space latent vibration makes the timbre turbidity, amplifiers and other equipment as there were not enough air circulation, easy overheating and aging. If you load the speakers into the wall, the sound effects will be stiff.

The second is stacked equipment. A lot of people love DVD, amplifier, tuner, digital analog converter, such as machine is placed overlapping, this will cause mutual interference, especially with the power interference is serious, a laser camera can make the hard tone, and produces depressive feeling. The correct method is to put the equipment on the sound shelf designed by the factory.

The third is the power plug. Good system of power plug and negative processing, the sound level is clear, natural and smooth; Positive and negative inconsistencies or uneven, the timbre will be hard and rough. The stereo

Fourth, the wiring is not fast and unclean. If the system sound hard, one of the reasons may be poor contact, such as plug, contact oxidation, touch dirt or grease, etc., so you should regularly check, keep contact surface clean.

The fifth is to use cloud or glass bearing equipment. Low cloud rock density, high resonance, can affect the sound effect. Glass density is higher than marble, but it is not thick and resonant. Can use granite or hemp, especially hemp, the density is highest, the bearing equipment is more ideal, but the thickness is more than 3 centimeters.

Sixth, the display of the speakers "adjust to the local conditions". Some people because indoor have other furniture first, and place the speaker place to move the furniture. Right should be decided to listen to the distance, then put the speaker on the seat and the wall between the 1/3, speakers of spacing for listeners and speakers direct distance of 0.7 times, ear height to listener and soprano flush unit as well.

Seventh, the wiring is not handled properly. Do not tie the power line with the signal line when processing the wiring, because ac power will affect the signal; The signal line or the horn line cannot be tied, otherwise it will affect the timbre. The line of signal or horn too long can be changed short. Many signal lines have directionality. Don't get it wrong.

Eight is to take for granted the room acoustics effect. In addition to the clear sound, sound insulation, more important is the processing of ultrasonic reflection, refraction, this need to consider the size of the room, size, strong degree, the use of materials, etc., if not an expert, even if will be decorated with luxury and beauty of the room, the sound is hard to achieve the best effect.

Nine is to imitate blindly. Do not imitate others blindly. If somebody else with short line, long horn line effect is good, this is because its level before and after and laser machine is balanced, and your equipment is not balanced, also to imitate, it will be difficult to achieve the same effect.

Ten is to deceive ourselves. Such as equipment play a certain concert effect is very good, and play another kind of music is not ideal, this suggests that the system has not yet reached the ideal level, need to learn more, listen more and more observation, thus improved.
