The first is to install a power filter. The most affected part of the sound system is the "contact-type" electromagnetic interference. The high-frequency noise generated by the motor unit of the refrigerator and washing machine, the lighting tube, and even the computer will inadvertently enter the power supply of the sound system. Sensitive circuit. Although these high-frequency noises far exceed the hearing range, the magical ears can feel the deterioration of the sound quality. These high-frequency noises do have a "modulation" effect on the audio signal of the sound. The most straightforward solution is to install a power filter. In addition to the power filters in the market, there are also very powerful "power processors". These products are usually expensive, but the effect is remarkable, which can effectively remove the power impurities and maximize the sound quality of the equipment. Some well-designed power filters also perform well, with good power capacity and dynamics. Another thing that is related to the power supply of the equipment is also easily overlooked. Strictly speaking, "landing" is actually part of the power supply, but "landing" usually involves the default power system configuration during the construction of the building. In general, buildings do not specialize in the "landing" of audio equipment, so the general "landing" situation is not ideal. Good "landing" can effectively suppress the influence of electromagnetic interference on the sound quality. When conditions permit, professionals can be asked to erect the building ground. The other part is the "flooring" of the audio equipment itself. Sometimes a ground wire is connected between the source and the casing of the amplifier to help the sound quality. This is the effect of zero potential integration between the devices. Helps suppress the effects of electromagnetic waves on sound quality. Of course, it involves the field of radio frequency interference. A seemingly inconspicuous ground line needs to be carefully selected, and even the connection direction will have different differences. Another topic related to the above-mentioned "landing" is "power phase". Usually, the power cord of audio equipment is IEC standard specification, and then the wall socket and internal wiring in the house are constructed according to the definition of IEC standard. Although the configuration does not affect the use of electrical appliances, the sound quality of the sound system is affected. In addition, for audio equipment using two-pin power plugs, plugging in different directions will actually have different sound performance (two power cords are divided into live and neutral), and the difference is not in accordance with the standard IEC device power outlet. The impact is the same. The sound player can judge the change of the sound by himself. A good set of audio equipment, power and ground are inseparable integration, good "landing" helps to improve the purity of the power supply, in the case of serious power pollution, power processing is already in the sound system Indispensable equipment. The pure power supply allows the audio equipment to achieve the highest potential, that is, to restore the original sound quality of the sound, a good "landing" is a part of a good power supply. By reconsolidating the power phase and zero potential consistency between the devices, the best power supply rejection performance of the entire audio system can be achieved, and all noises that affect the sound quality are blocked, and the best original music is restored.
