General audio players in the mind and the power supply is not included in the sound system of consideration, and in fact the performance of the sound system under power supply prime quality has a great influence, especially the modern high frequency communications equipment with environment, the power source of the contaminated situation in household also has become increasingly serious and affect the sound system of sound performance. In order to improve the power supply power supply purity, we can be considered from various aspects.

First is equipped with power supply filter. Sound system is the biggest impact of contact conduction electromagnetic interference, the refrigerator and washing machine motor, lighting light pipe, and even computer generated by high frequency noise will relentlessly into a sound system of power supply and affect sensitive circuits. Although these high frequency noise is far more than hearing range, but magical ear can feel its sound quality degradation. The high frequency noise will indeed for stereo audio signals generated "modulation" role, the most direct solution is to add the power filter. RBX - 9 _ copies. JPG

Besides anecdotal power supply filter, also has a particularly good efficacy of "power processor", usually this kind of product price is expensive, but the effect is remarkable, can effectively remove impurities, play the sound quality equipment to the greatest extent. Some well-designed power filter has good performance, the power capacity with dynamic aspects. RBX - 10 _ copies. JPG

Another things associated with the equipment of power supply also susceptible to ignore, strictly in terms of "ground" is actually a part of power supply, but the "ground" usually involves building during construction is the power of the default system configuration. In general, the building will not do special handling for audio equipment of the "ground", so "grounding" general condition is not ideal. Good "grounding" can effectively restrain electromagnetic interference effect on sound quality, in conditions allow, can ask professional building ground construction.

Related to the "ground" another topic is "the power phase", usually audio equipment of the power cord is IEC standard specifications, followed by the socket on the wall of the house and the internal wiring is in accordance with the definition of IEC standard to construction, although incorrect configuration does not affect the use of electrical appliances, let the sound system of quality is affected. In addition, the use of two type power plug of the audio equipment, plug it in different direction will have different sound (two power cord wire and zero line), the differences and not in accordance with the standard of IEC device outlet affected by the same. Audio player can try to determine sound change.

A good stereo equipment, power supply and ground wire is an integral one, "earth" can help you to improve the power of purity, in power was seriously polluted by power handling is to pay attention to in the sound system can not be lack of equipment.
