Audio connection cable for the sound quality of the performance of different degrees, different materials of the wire there will be a different sense of hearing.
Film "Infernal Affairs" Andy Lau and Tony Leung decorated in a retro stereo store. Andy audition tube amp, Tony recommended a tube amp with a Hong Kong-Hong Kong-produced audio cable performance comparable to "hundreds of thousands of European goods," the sound "sweet treble, in pitch, bass pure, in short, in a word, that is transparent. " They sat side by side, calm down the screen, like the freezing air in general, Tsai Chin's "forgotten moments" in the yellow light of the screen to ring. Andy then a cable of their own choosing, "listen to old music, the better." Voice sounded again, "really better"
Sound from the front (such as players, Dan Ji) to wire the various parts are an integral part of sound quality, so enthusiasts can pursue this music is not he, precisely because as a child's building blocks with wire, as can the ever-changing. In addition to audio cable replacement, in fact, we usually have the most contact headphone \ ear also can replace the wire, the current number of brands offer high-end headphones ear wire design that can be replaced. ER4 classic series such as an iron, Shure SE530, UE TF10, etc. These can be changed with the original habitat wire design, in order to meet the fans of the fun, so the sound quality varied. Strong ability of friends, but also their own equipment to try to replace the wire, perhaps a change in the ordinary face of the sound equipment will be able to make you pleasantly surprised. That kind of material, how will it sound?
First, the copper
From the species point of view, the current production of audio cables commonly used materials are copper, silver and various alloys, and nickel, rhodium, carbon for the production of raw materials can often see the line.
Copper is the most commonly used system for our line of conductive material. Copper in accordance with national standards (making use of copper wire) must be greater than 99.7% purity, resistivity is less than 17.24n, when the tinned wire and silver wire are subject to change. Another common definition of purity is the "N". Just play the line of people often hear this is a class of several N-line argument. In fact N is the word "NINE" abbreviation. We often hear 4N line actually represents the purity of the line material is 99.99%, while the 6N is its purity 99.9999%. Audio cable from the point of view, the general 4N line will suffice. However, It should be noted that, N is the line within the convention, there is no specific international standards, and no clear industry standard. Therefore, some plants produce 6N line may actually be not as good as some of the plant 4N line.
TPC: electrolytic copper, that is, we generally produce the raw material of copper materials.
OFC: Oxygen-free copper, electrolytic copper in the removal of some oxygen molecules and impurities, usually about the purity of 99.99% is audio with a line of minimum standards, it is often said 4N copper.
Hi-OFC: high conductivity oxygen-free copper, by further removal of copper oxide, and removal of other magazines, the purity of copper increased to 99.99%, while after processing and heat treatment, as far as possible the arrangement of atoms in the grain the same lattice as much as possible, to improve conductivity.
LC-OFC: way through machining and heat treatment of the high-conductivity oxygen-free copper grain growth, reducing the wire signal distortion caused by grain boundaries.
PCOCC: single-crystal oxygen-free copper in the smelting of copper, the use of directional growth and rapid solidification method, the growth of elongated crystals of copper, the longest up to 100 meters, the conductors within the boundaries disappear, virtually eliminating graincommunity and the oxides of the signal distortion effects.
PSC: Solid Smooth Copper: As we wire drawing process, the copper surface is not smooth and the surface oxidation of impurities into and affect the smoothness of the signal transmission, especially in high-frequency signal. Due to skin effect, high-frequency signal transmission only on the surface, the surface is not smooth and dirty poor and the high frequency signal transmission distortion (like a car to open the road in the potholes). PSC is PCOCC wire on the basis of surface polishing and removal of impurities.
Third, the silver material
Silver is also commonly used in manufacturing our line of conductive material. Because silver is more expensive, generally only for the surface material, copper wire from the center to the low frequency, high frequency silver layer from the surface.
Conductive properties of silver a little better than copper, but slightly lower resistivity, ie high conductivity, copper skin effect than a little obvious, but why in the silver wire used in high frequency? Because the chemical properties of silver is more stable than copper, its surface is easily oxidized, so it's a good high-frequency transmission performance than copper, in high-frequency lines, such as video cable, digital signal level in the superficial layer of material, of course, in some high-end The commonly used silver wire in the material. First, there is better conductivity, followed by a high-end line of better commercial value.
Silver material also OFS, HI-OFS, PCOSC, PSS of different purity and grade of the points.
Third, the copper alloy
Copper alloy, which is a less common system of line conductor material, commonly known as brass. Major components of copper, silver, zinc alloy. Now very popular in high-grade wire in a material.
Copper alloy of copper with the traditional sound very different, for some equipment is appropriate, it is inappropriate for some equipment, but also can be said that the system has a large line of personalized materials. Resistance than the copper alloy of copper an order of magnitude, so it's not obvious skin effect than copper, its high transmission and low frequency transmissions, more consistent. While its good oxidation resistance than copper, its surface is more conducive to high-frequency transmission. Disadvantages are also obvious, and its resistivity is high, long-distance transmission loss is too high, in the long-distance transmission needs of professional applications is not applicable. Meanwhile, the high and low frequency transmission characteristics and copper are some differences as to cause the normal balance of copper wire debug the system with a copper alloy material will produce a new balance, so its use of certain limitations, usually presents bright treble
Fourth, the carbon fiber
Carbon fiber, carbon fiber conductor is mainly used in the past in some of the high input impedance of the instruments and medical equipment on. Wire used for audio material is still relatively small.
Carbon fiber anti-aging, anti-oxidation, the tensile strength is very excellent. It's a very high internal resistance than the copper wire about three orders of magnitude, while its diameter is generally in a few, so it's the skin effect is not obvious. The above characteristics of the decision is to adapt to high carbon fiber signal transmission, but it is also very obvious shortcomings, it's resistance is high, 1 meter long signal line resistance is generally a few hundred ohms, while the same size of copper wire only a few tenths of ohms or less, for the input impedance is very low for the equipment, causing signal attenuation, dynamic compression. Occasions in the high current is not suitable. VDH's the third one more than 300 ten thousand carbon fibers of the speaker wire, up to 70 per meter impedance resistor, has been higher than the signal line resistance, commonly used speaker cable length 3 meters. There are more than 0.2 × 2 speakers divider resistance within the inductor resistance, resistance even more than one-tenth speaker, severely reducing the damping, low-impedance for low frequency and large speaker box very bad, let alone long-distance transmission needs professional situations, it's finished with copper wire production process is also different.
Different audio wire material, a different sound effects, to choose according to their needs, professional decision height. Dongguan Xin Electronics Co., Ltd. United Tel :0769 -38,837,666 |
