To acoustics, of acoustics quality is good still crucial, because lacked the simple sense of true nature, that also lost the truest quality, share with everybody below 9 let acoustics sound quality more beautiful method.
Method 1: every six months to clean the contact once
Soon after exposure to the air, the surface layer of the metal will oxidize, lose luster, and become dull. Even if the surface of the signal line plug after gold-plated treatment, it is not easy to oxidize, and the fuselage plug and close contact, but for a long time, there will still be a certain degree of oxidation resulting in bad contact, so at most every six months to clean once. Just daub the contact with cotton and alcohol. After this heavy work, the contact will return to the best contact and the sound will be clear and transparent.
Method 2: clean CD machine laser record head
Obviously, the CD player has only a tiny area, but it can read the marks on the CD, so even the slightest speck of dust attached to the CD player can affect the accuracy of the readings. Although CD machine mostly has airtight fuselage, but do not forget to have the gap to let dust take advantage of in the process that often gives a dish to enter dish, come down for a period of time, sing head surface certainly has left more or less dust, at this moment want to turn on open cover screw, play open cover to point with cotton stick directly on alcohol to clean. Although there are all sorts of clean CD disc on market, but you spent a few dollars, those so - called wash CD disc may just rely on a row of brush to sweep dust or use suede face and so on to rely on rotation to remove dust, the effect is not as good as direct use cotton stick thoroughly. After the CD machine that did not wash one's hair long when you is clean finished, the meeting that listens to again makes a person to have the feeling that opens a gauze, and high frequency replies the clear of old days, detail is pleasant also much. This is done about once a year, and even with Pioneer's turntable system (with the laser head down instead of up), dust is attracted by the static electricity attached to the turntable, so it doesn't take much time.
Method 3: avoid machine stack as far as possible
Due to environmental problems, it is impossible to stack up the equipment. If possible, you should try to place the main CD source and amplifying part independently, because overlapping will lead to harmonic vibration and affect the machine. When the trumpet playing music, vibrating air make equipment with vibration, piled up two machine will each other to preach harmonic vibration, make music in the subtle message fuzzy, and interfere with the transmission spectrum, cause a kind of sound pollution, and as one is a CD player, his own play disc motor turn even harmonic vibration amplitude have been intensified, influence is even greater. So the equipment should be placed independently on the stable rack.
Method 4: split power supply and the host, mono channel between the rear stage to keep a distance
Nowadays, even a lot of mid-price front stages have a box size split power supply, simply separating the fire bull and the main engine into two parts, the advantage of course is that the internal parts of the fire bull and the possible interference between the isolation. If the split power supply is placed next to the front level, it will be a little meaningless, quickly put it away from the front level, such as the rack on another level, real-time can hear the overall separation has been improved, the audio and video will be more accurate. Monophonic hind level is also the same, conditional two equipment is put apart a bit, assure advantageous harmless.
