Tsіkave reading for cables. Secrets of the Chi cable
Switching of the audio part to the complex
Let's continue the rose. This article deals with the switching of audio signals between components of a home theater complex. Crimea is happy about the good commutation, this article has respect for cables, as well as the problem of saving pennies with the preparation of self-contained cables. Chi vartuє ovchinki vychinki?
Cables
Various types of interconnect cables
Interblock cables with foldable bends, lower columns. Here, there is a different design of the cable itself, and there is a significant increase in the number of innovations, as in the plan of vicorous materials of conductors, so in the field of dielectrics, on the basis of speaker lines. In a different way, the obov'yazkova presence of roses on both ends of the cable. Well, obviously, today's inter-block cable can be easily seen without a presentable and stylish look not only roses, but the cable itself.
And on the market at once you can hit the “interblockers” for whatever taste, color and hamanets. You can buy a ready-made cable in a package at once for $10 and $500. There is a lot to be found here not only because of the quality of the cable, but also because of the "branding" of the virobnik (its reputation and popularity). However, today we are talking about the most affordable interconnect cables, and not about super-luxury wires in gold-plated boxes with an oxamite interior.
All interconnects can be divided into two main categories: cables oriented to the transmission of an analog signal (the so-called "interconnects" or "analogue" cables), and cables designated for the transmission of digital data, which are simply called "digital" cables.
"Analog" interconnect cables
Danish type of inter-block insurance for the transmission of signals from the dzherel to the outbuildings, the commutator, the switch, and so on. For this type of sound, sound the sound of the screening of the audio cable, prompting for the coaxial scheme of the wiring of the conductors, the central conductor of thefts in the direction of the screen, the sound of the impersonal thin metal wires. Such a design allows you to hide in the vicinity of electric devices and allows you to conduct a low-current signal from one component to the smallest with minimal costs. To connect such cables to the building, hand-held RCA connectors are installed (popularly known as "tulips" or "pins"), which are the most wide-ranging roses in popular audio equipment. Sound for the purpose of the “interblock cable” step: the back, which consists of two cables and 4 RCA sockets (to put it simply, the cable “2 tulips to 2 tulips”), the building transmits a signal of two channels from one system component to іnshіy.
"Digital" cables
For its part, this type of cable is divided into two types: cables designed to transmit a digital signal to an electric stream (“digital coax” among the people) and to transmit a digital signal to a light source (optical fiber or, more simply, “optical” cables) . Let's start with the first ones.
This cable is practically not exposed to the sound of a sizable "analog" interconnect. The call of the retailer is more than at the time of the other zadnuvach. Tobto, "digital coax" is only one cable with roses on the ends (sound with RCA roses). Abo, it seems simpler, the cable is called “1 tulip - 1 tulip”. The “digital coax” is being prepared only for the coaxial circuit (for which reason the name is different), moreover, for the “analog interconnector”, the “digital coax” is to blame for the mother of the 75 ohm opir.
It’s also very bad, sob and roses are small, so is a fluffy opir of 75 ohms, it’s smart [bazhana, but not obov’yazkov] smart only when preparing to finish expensive “butovyh” and mayzhe all professional cables.
І, nareshti, fiber optic cables. Everything is simple here: digital signal It is transmitted from a bright light through a fiber optic fiber, as it can be prepared with a special polymer (with relatively inexpensive cables and cables of an average price category), and with a special flexible cable (cable cables are more expensive).
Optical cables can be a little plus in front of electrical coaxes: first, potentially building optics can transmit more communication digital information. In another way, fiber optics allows for ground-to-ground decoupling between two components (this is especially true when connected system unit computer to the receiver). However, the optical cable is expensive, and inexpensive implementation (up to $40-50) and data transmission schemes for the budgetary owner do not allow you to enjoy all the advantages of optics. So, if you don’t want to pay over $30-40 for a “digital” cable (call yourself for a variety of “digital” cables and bathe most often up to a DVD player and a receiver of a cob and an average level), then it’s better to pay respect to a coaxial “digital” » Cable.
Parts of nutrition with tsієї topics:
And yet - what is more beautiful for the sound: "optics" or "coax"?
If you talk about middle-class components ($400-800 per leather), then the fundamental difference in sound is nothing. More than that, the efficiency of what is between "optics" and "coax" in retail will not be felt, 99% more expensive. So, plug it in as you wish, but remember that for other equals, “coax” may be cheaper for a similar one for the “optics” class.
What is the maximum length of a digital cable?
For an optical cable - 7 meters. For an "electrical coax" there are no such precise limits, the chips should lie in the quality of the cable itself. With the use of a good yakіsny coaxial cable, digital data can be transmitted 10-15 meters and more without problems.
More satellite receivers can no longer have an optical digital output - why buy an expensive cable?
No, not varto. On the right, in that there is no such thing as sound quality in a satellite TV box (although the bitrate of a digital audio data stream is not high), if you go to a music DVD or, say, a CD, it will be more than enough to put on a simple optical cable for $ 10-15.
It is also planned to connect a video recorder, a game console, karaoke, a tuner or similar outbuildings, then regardless of the price category of these devices, you can get around inexpensive "interblockers" for $ 10-20, or you can make them independently (for a lower price). Yakіsny interblokovy cable maє sens kupuvati less for the connection of a good stationary CD-player or DVD-A/SACD player with a sub-powered one or dosing with a yakіsnym receiver. Let's say, for a mid-range CD player ($300-500), you can buy an interconnect cable for $40-70. Far behind growing - fallow in the class of components. If you don't believe in the construction of cables to plug into the sound, then you can buy an inexpensive "interconnector" for a good CD player (or a good DVD-A / SACD player) or use the cable itself.
Can you protect yourself by making the interconnect cable yourself?
If you can solder, then on the purchase of inter-unit cables you can earn a lot of money. As already mentioned, most of the components of the system (karaoke, video recorder, okremiya tuner) do not require especially low cables, so for connecting these components it is possible and necessary to use self-contained cables. What can you see? Perfectly. Moreover, not only from the financial point of view, but also from the point of view of the quality (!) On the right, for the preparation of self-contained interconnect cables, good (albeit inexpensive) professional microphone or instrumental cables (Proel, Canare, Tasker and so on) are used there were few professional cables), as they are sold at any professional sound equipment store. And the quality of these cables sound on the head of a thing, lower in inexpensive "branded" interconnects. The cost per meter of such a professional cable is about $1. Some RCA roses will cost $1-2 apiece (I'm guessing, they need 4). Axis and go out, scho garny self-contained cable with roses costs $5-10. At the same time, such an “interconnector” will be on a par with a purchased interconnect cable for about 30 dollars, or more. Do not forget, even if you have a ready-made cable, you pay for a box, advertising, a payoff robot, and a sales assistant.
Can you make a good interconnect cable for the CD player?
A lot of people are so frustrated, but they also buy more laconic microphones or instrumental cables for $1.5-2 per meter and good roses for $2-3 apiece. If you use the best solder and work everything correctly, then such a “self-made” interconnect cable can easily compete in sound with a Hi-Fi class interconnect cable for $ 50-70 or more expensive.
Whoever does not believe that the building cables "sound" - unambiguously solder their own similar interconnect cable itself. Well, if you doubt that the purchased cable can be "replayed" self-contained, then fix it like this: solder (or ask a person for the sake of it) one "interconnector" from the microphone cable and RCA sockets. Let's go to the great salon or the store selling Hi-Fi and pick up the outpost of the flock of those who come for the price of ready-made inter-blockers and pickers. Change the sound at home, connect via wire to the CD-player, then prepare the cables, then self-contained. If you want, in short, if you want to connect something else - it will be more honest "sleep" listening. There, you can see two points for yourself: what is the difference in the sound of cables, and also understand how much thicker / better self-contained cable, vrakhovyuchi, that the fault is cheaper and purchased. If you buy cables "overcome", then if you buy a broken cable, you can use it to connect the same video recorder. And if you “overcome” self-confident - please. In this rank, you can spare more than one hundred dollars on cables, yakscho Behind the sound, self-contained cables power you.
I believe that the cable changes the sound of the system, but I don't know which one to choose.
There is nothing simple. Go to a great salon or a store selling Hi-Fi, take a pickup from the outpost of the “interblock” splinter, like a match for the price, and equalize their sound on your system. Itself on your system and at your room. So you can find out more precisely about the nature of the "sound" of the skin cable.
Can you make a "digital" cable yourself?
So, just like talking about a "digital" coaxial cable, the shards of preparing an optical cable in your home minds will take too much strength, or even a penny, it's easier to buy ready. And the “digital coax” axis can be built by itself, especially since your system is composed of components of a cob or an average level. So let’s take care of the preparation of a digital cable, so you don’t burn the bazhannyam for a big penny for what you buy, knowing that in practice I’ll win the type of what you buy from your vpadk will not be for sure. Otzhe, yakі vymogi vysuvayutsya to "digital coax"? First - coaxial design, and in a different way - fluffy opir 75 Ohm. Tsim Wimogam satisfies the antenna cable. So-so, the most basic antenna cable ($ 0.8-1.5 per meter). If it is possible, then you can buy a low-frequency antenna or video cable (for example, the same Canare) for a price of $ 0.8-3 per meter from a professional equipment store, chips for a high quality such a cable will be guaranteed to be shorter, lower antenna, which is sold on the radio, even though And even better, after the words of the seller.
It is important to remember: if you don’t have expensive components, if you plan to work with a cable of small length (1-2 meters), then you can not worry about injecting a digital cable into the sound of the system, you can wind a self-contained “digital coax” (in the photo below), choosing a good antenna or video cable with two good RCA roses (such a cable with roses will cost $ 4-6 at once), there will be nothing more expensive for any purchased digital coaxial cable for tens of dollars. Hiba scho you will not have a garnet box and fashionable nameplates on roses and cables. Vtіm, and self-confident so badly can look.
Switching
On the schematic image There are no inputs/outputs of video signals in the devices, so they didn’t stink, even today there are only about the switching of audio signals.
Connecting a DVD player to an AV receiver
Everything here is easy to do. All sound flow digital look transmitted over one "digital" cable: optical or coaxial electric (there is only a lesser way to deliver the signal, but the essence is too much: deliver the digital stream from the dzherel to the decoder). Therefore, the digital output of the DVD player needs to be connected to the receiver's digital input with one "digital" cable. Like myself, I already rose to the occasion. This type of DVD-player will have “Syria” digital flow, and the “brains” of the receiver will be changed to rich-channel sound, or to stereo sound (to lie in the format of the external digital stream and to tune the receiver). If your DVD player is equipped with a rich-channel sound decoder, but is a device of the same class (aka prices) with an AV receiver, then the decoder will not sound like a sound, the decoder and DAC (digital-to-analog converting) receiver will not higher, however, they will give wider possibilities for adjusting the sound for a specific listening application.
What to rob on the scheme of another CD-player? Він є one з possible options expansion of the complex with the method of improving the creation of music. It's no secret that mid-class DVD-players (do not seem to be about budget models) may not see the benefits of playing music, often doing the same for cheap stationary CD-players. So you can’t boast of good DACs and a lot of AV receivers of the middle class ($500-600). That's why a lot of people know how to go: having bought a decent AV receiver with a rich analog input, buy a cheap DVD player for movies (having put your hand on your heart, you can say that a DVD player for $ 150-200 shows not those that are much louder , Chim device for $ 400-600, especially as you marvel at the picture on the TV 21 "-29"), the decoding sound of the rich channel sound will be taken care of by all one receiver, which means that the DVD player will only need digital audiovisual And more or less, the quality of the image is decent. And to save money, go for the purchase of an expensive (I want for $400-450) CD-player. From which viewpoint the Lord of the system takes away that yakіsny sound with the creation of music and even the disgrace of the cinema.
So the axis, purchases of a CD player is connected not to the CD input on the receiver, as you might think, but to the rich-channel analog input itself. Why? Let's take a look at the diagram:
If you marvel at the diagram, then you can work two possible ways analog signal in the middle of the receiver (from the analog inputs to the switch) In this way, the analog signal is digitized (ADC - analog-to-digital conversion), then with the already digitized signal, the DSP processor is used, which “for the client’s needs” can distribute the stereo signal to a rich channel (say, the Dolby Pro Logic II algorithm), filter low frequencies put it on a subwoofer, process the sound with an equalizer or one of the presets of the spacious modes. After all these manipulations, the signal is re-transformed to an analog (DAC - digital-analog conversion) and then go to the switch. But the problem is that with a “weak lank” in this language, it’s not the DAC style, the ADC slicks, which, wisely, and signifies the sound of the sound. And the ADC in the receivers should sound in the middle, if you want to do it all the way to digitize the audio signal from the video recorder, tuner or karaoke. And if you plug in a good CD player, you will immediately feel that the sound of your good CD player has become cheap and cheap. To increase the potential of your CD player, you need to connect yourself to the front channels of the rich channel input. However, only the signal from the rich-channel input is not passed on to the signal for the procedure ADC > DSP > DAC (lower half of the circuit). So, the signal from the multiple channel analog input goes straight to front pidsiluvach, And then let's take a p_dsiluvach puffiness. And behind this principle, the majority of modern AV receivers is more important. To change the "honesty" of the rich-channel input of the receiver is even simpler: for a signal that goes to the rich-channel input, it is not due to the availability of daily sound control (equalizer, timbre block *, spacious sound modes) - the loudness control is more practical. Everything is fine with my vipad.
* obviously, the timbre block of the receiver is not analogous, the visible mechanical handles on the front panel are weak.
class vishche
Well, if you have a serious receiver and a classic DVD player with the ability to play DVD-Audio and/or SACD discs, then you don't need an okremium CD player, better for everything. Switching the components will also be done in this way: for movies, the digital connection is left out (“coaxial” or “optical” is not so important), and for DVD-A / SACD discs, you need to speed up the analog connection, using the 6-channel output of the DVD player decoder with a rich channel input of the receiver with 3 pairs of decent interconnect cables, the shards in this type of DAC and the player will be sing-song for t, as installed in the receiver, that th, before that, the receiver sing-alongly simply “doesn’t understand” for the number may be only new and expensive models), but not more than SACD (Super Audio CD). So, two types of connections are boldly victorious.
Other components (karaoke, VCR, cassette deck and so on) can be connected to the receiver's optional analog inputs. Like the sound of these devices from internal processes, like a receiver, it does not affect hearing a little.
Burying at the reality of the appearance, we reveal new depths ...
Go, vtim, not about UFOs and transmigration of souls, but about a trivial cable.
However, this very cable, regardless of its outer (and one inner) simplicity, has a lot of surprises in itself, as if it does not have a clear scientific grounding. The concept of voodoo science (chaklunskaya science) has taken root in the midst of audio cables high quality, having expanded potim and the area of accessories: all the cones, the bases too. It is impossible to reveal the reason for the sharp cracks in the “sounding” cables. Those who do not stick in practice, do not believe, especially technology. How can it be?! In a range of up to 20 kHz, but if the conductor is supported by ten to a hundred parts of Ohm - there may be a difference! But you can change the color of the cable, nothing will change! Turn on - and change, do not reach the flower on the right. For a certified engineer, it's a shock, and it's zhorstokishy, the lower scores for his diploma. The poor engineer begins to judiciously control the surface effect, dielectric absorption, group hour tricks (otherwise, Ohm's law is not avoided). Bidolashny, who had tried to explain with a hastily beaten hypothesis, clearly a little difference, was spared, as if he didn’t think of laying a bet!
І in normal science, and in її "voodoo"-surrogates figure your own physical realities.
Same:
Surface effect. As the frequency increases, the struma increases closer to the surface of the conductor and changes in the middle. We remember this phenomenon for enough high frequencies, which means to change the sound range. Theoretically. Ale dosvіdchenі "cablers" stverdzhuyut, scho "those drіt at the center of the cable secures the garne of the passage of basses, thin w - on the periphery - do not let the high ones weaken." In practice, such cables sound to demonstrate a deep bass and ringing "top".
Group Hour. "Razsharuvannya" frequency range, if different components change the phase in a different way and as a result come "to the finish line" with less hourly speeds, lower "at the start". The reason for the difference in parameters of inductance and capacitance is also due to the surface effect (which increases the conductor’s operating at a high frequency).
Electromagnetic interaction. Let's make an inconsistent shkіlny dosvіd: through two parallel wires pass a constant strum, and as if it's straight ahead, the darts come out one in one, twisting in an arc, otherwise they are attracted. Similar effects are energized by the stream through a magnetic field directed at the conductor. So, a part of the signal energy in the cable is stained marno! Navit regardless of the weight of that inertness of the cable, the mutual injection of the sudan conductors with the same anti-phase signals is overwhelmed: de strum, there is a magnetic field. In interblock cables, the stream is practically equal to zero, and then a change in voltage is transmitted there, also, the interaction is also saved - through an electric field. And “voodoo” to include us, that nothing can be bad!
Explorer. As you can see, the cables roar from the midi. This miraculous material: the nursery opir midi is not large, and in this medium one acts (moreover, the trio) is less srіblu - to the point of speech, the gold is exalted. Ale mid midi rіzna. It is important that a good cable cannot be made from the same “brudnoy” midi, which is a great electric. Copper is guilty of being not just pure, but pure (99.999% Cu), її is usually called “sour-free”. The purer the copper, the less it is weak to oxidation, the houses of various metals play the role of catalysts and speed up the oxidation upon contact with repetitions. Vlasne, what the hell is wrong? The smelting of oxides and oxides on the surface of the conductor can be the mother of the conductors of power, with the help of rich support, the metal itself. At the same time, in the surface sphere, the struma thickness at high frequencies is maximum.
They are foreign metals, which have come to the rest of the “nine”, which are brimming with rosemaries and valence, inevitably destroy the regularity of the crystalline ridges. Possibly, it is really unacceptable for electrons to jump over the crossings, like us - to go by car along a nerіvnoy road. And especially the hatred of the champions of purity of sound and midi shouting houses of metals in the group of salaries - cobalt, nickel, yakі mayut, like the same zalіzo, magnetic power. Razdratuvannya call for a small waste of signal energy on the reorientation of magnetic domains, as they can be blamed for the obviousness of the clusters of ions of these metals! Namely, but there are cable models, in which the conductors are not made of metal, but of carbon composite! There is definitely no magnetism here, although the opir is richly high, lower at midi. These cables (Van Den Hull) are a prime example of miraculous sound, even for a penny.
Let alone the purity of the signal, it’s unlikely that any of the graduate engineers compete with the “voodooists”. Remains often appealing to the molecular structure of the midi, too, under the armchair, that the sound is very strong. Whether metal can have a polycrystalline structure. Ale, the greatest copper rolled stock is made up of fibers, which are sintered one by one, and the length of these fibers is about a millimeter. Special technologies allow zbіshuvati її little not to inconsistency - so that in the boundaries of one cable the fibers appear without interruption. Tse improve the characteristics of the cable, changing the internal unevenness.
Ale sho mi all about mid. Come on! Audiophiles are subdivided into two tabori, medium and silver. Having offended, they could reach a readable sound of authority. For example, mid-sound to sound tіlesnіshe, velvety, just like srіblo - easily, poіtryano and supra-soundingly clear. What to see for sure - on the right relish. The combination of silver and midi in one cable did not reconcile “medium” and “siberian”. If you want among similar models of cables, they trap even more badly. Nareshti, srіbnі midnі droti zastosovuetsya even more often, especially like video and digital: there the superficial effect is clearly marked, and srіbne pokrittya yogo deshcho zglazhuє. Tsіlіsne well srіblo, dragging with a great oversized cable, is not cheap. Srіbny acoustic cable often costs over 1000 c.u. per running metre.
isolation. You have mercy, because you know that everything is broken like metal in the cable. Isolation! It has only two basic functions: wet insulation and mechanical. The other powers are shkіdlі. I nasampered - dielectric absorption.
On the right, in that part of the energy of the signal goes to the orientation of dipole molecules in the polymer structure of the dielectric. That is warm, which is settled in the aftermath of the “internal rubbish”. Part of the energy turns, and tse louder, lower її spend: "ricochet" sweeping the fine details, shards of the troch are seen by the hour. This process is so often stale, so to make the picture even more confusing. 
Why, the insulation balls can accumulate a static charge, which injects a signal. Therefore, you will never use a good cable with polychlorvinyl insulation of conductors (mostly the outer ball works with it, but with nylon, silicone, too). Polypropylene, polystyrene, polycarbonate are good dielectrics (stinks accumulate in yak capacitors). Nabagato girshe - polyethylene, lavsan. The king of us dielectrics is teflon. Obviously, the wine is expensive, not necessary technological (zocrema, teflon to reach a high melting point), but it stagnates more often. On the other hand, the backs of the polymers of the “lower” gait allow you to noticeably get close to the “royal person”. Povitrya is even closer to vacuum - an ideal dielectric. Obviously, Teflon backing is leading here with the great wind.
In order to ensure the stack of static charges, the insulator is sometimes impregnated with graphite powder (when the electrical conductivity becomes scanty, the shards of a particle of coal do not stick one by one). Tsієyu well as a method in deakih cables to serve as a sov. drainage drill: special guide grounding on one end of the cable. But why are you charging the impromptu streams on the signal conductors? Like a drainage drіt (or a whole screen) of rotting on the surface of the cable, or if it is not very deep, it will vibrate the electrical potential of the internal and external surface insulation.
Geometry. Special variability in the design of cables is not to be feared. Standard options: standard or twisted pair, hard-wired or shielded, and coaxial design. Remain victorious at high frequencies: for video and digital cables, it is necessary to trim the standard wind (characteristic) support (sound 75 ohms, in the other 50 or 110 ohms). It is easy to reach: the choice of the required sp_v_dnoshnennia diameters of the central conductor and the empty screen. On top of it, there may be one or more screens insulated with a ball of dielectric - for the defense of the ethereal passages, the rivulet of which in great places becomes more and more remarkable. Zokrema, VID “Digital Efir background”, Yakilessly vigilantly, through the great Kilki of digital technicians, the same ash, especially Dimmerev, pusko, sinusois of the sinuscular of the sino of the sulfur, І, nareshti, trivial induction in a measure of 50 Hz (and other harmonics of 100 Hz) often-densely appear like an unacceptable hum. Therefore, not only high-frequency coaxial cables are screened, but inter-unit "bets" (acoustic cables can be dispensed with without a screen).
An unscreened cable often sounds much better, a lower screened cable may be due to the fact that the energy of the signal does not affect the direction of the stream in the screen. As an “electromagnetic microclimate” it allows you to get along without a screen (so the noise level does not lead to an increase in noise and low-frequency hum), additional audiophile information will allow you to overcome the “bare” cable.
Let's guess again the butt of parallel wires, as they are attracted one to one, or they are stale in mutual directing fast strumu. Let the dart go under a deakim kut, mutually weakening and bending, if this kut becomes straight. To this very fact, a pair of popular ones is twisted, lower zvichayna: darts in it are known under the deakim kut one to one. In addition, zvivayuchis in a spiral, the stench is more likely to "average" guidance. Crossovers, aimed at the wires, are in-phase, they are less, lower in anti-phase, especially in balanced circuits and cables (there are two “hot” conductors, which can be analogous, but out-of-phase signals, and high-voltage “earths”). Balanced cables allow, without special shifts (in the direct direction), to transmit weak signals on significant frequencies, the sound and the balance configuration.
There are also extreme cable designs, cut between conductors at some true 90°.
Dali. Є single-core and multi-core darts and, vidpovidno, cables. Single-core zestrichayutsya pomіtno rіdshe. Sometimes in one cable they combine lived a different cut, relying on the optimal "recipe" of experimental knowledge. This is possible: in every case, in the case of cables, the empirical method, without any doubt, prevails over the analytical one. It is impossible to "open" a cable with a given sound character, and with a given physical parameters - a natural practice.
Luggage cable is easy to use, whether it is necessary to cut it for the sake of saving mechanical power (this is especially true in acoustic cables). The more the bands are, the more the effects of the surface effect fit in: if the surface increases, the more the gap increases, the more the support for the different frequencies becomes uneven. The richly veined wire in this sense does not reduce anything, the lower one is single-core with the very same peretina, before that, the veins come out on the surface, then they “pirnayut” at the clay, introducing additional insignificance. Zovsіm іnsha rіch at the time of zastosuvannya lttsendratіv: rich-core cables with individual skin insulation lived, as if they were like an silicon cable, those conductivities are confused, not greater than the surface effect. Another decision was propagated by an American firm Kogan Hall: empty thin-walled copper tubes. However, it is impractical because of their hardness and fragility. Nayts_kav_shiy at the plan of geometry directly - cables with flat conductors. Rozkocheny at thin smuzhku foil provіdnik dosit great overcut can significantly more surface povіvnjano z tsіlindrіchnym, and at the same time practical liberation of glibini. Until then, such an acoustic cable does not “capture” anything.
The geometry of the insulator, as a rule, constantly confirms the geometry of the conductor. Often, conductors are not just isolated one by one with a dielectric ball, but they are separated by a distance. With the help of the insulation of the insulator, you can change the diameter of the conductor, which, in the case of your choice, may be from the left sides of the discharges.
Then: the sound insulation defeats the function of the mechanical damping of the cable: acoustic vibrations (for example, music) call out vibrations, with which the signal can be modulated by these vibrations. For example, in a multi-core cable - through a short contact between the veins, in a cable of any type - through instability between conductors. "Voodoosti" is seriously put before the "microphone effect" cable. And in the face of stupidity, their caution brought melancholy to this tide, which was brought about by practice.
Now a few words about firms, yakі zrobili vagomy contributed to the arsenal of masterpieces of cable art.
audioquest(USA). A great assortment of cables, whether they are of any use, a wonderful reputation that is guaranteed maximum return for the amount invested. Mass of patented advanced technologies. HyperLitz- improved litz wire: insulated single-core conductors make an empty cylinder, which, apart from other advantages, including the irregularity of electromagnetic interactions at the cable. SST (Spread Spectrum Technology, expanded spectrum technology) vicorist difference of conductors at the litz wire. Tse robit accessible, as the author stverdzhuyut, thinly "lashed" the cable for equal transmission of a wide spectrum of frequencies. Company audioquest first began to zastosovuvat dovgovoloknista midi and sreblo, as well as "repair the pillow" - the conductor contacts with the insulating tube only along one line, relying on the "dielectrically ideal" surfaced core. In rich models, soldering seals (in terminals) are replaced by seals or combinations - crimping and soldering, leaving more “preserved” contact, protecting metal from oxidation, that safer more minerality. Vzagali, whether it be some kind of sprit, navit srіblo, act for bagatma with the characteristics of midi and srіblu. 
Monster Cable(USA). Magnificent assortment, finished with a folding design, yak_sn_ tips. A lot of wins, the leaders of the company are trying to take leadership in the market, regardless of the strength of competition for the rest of the 10-15 years.
Kimber cable(USA). The company's handwriting is a “braid” with a few rich-bodied medium or silver darts at the look of “kiska”, the veins of various overcuts. Most models are not screened. Isolation is more important than teflon, cream found models. Characteristic m'yake nobler sound. Light bestsellers - speaker cables 4TCі 8TS, as well as interblock PBJ- one of the most popular budget cables. Ten years ago, a record was set: the company released the Black Python speaker cable from the hand of the worker, the outer shell was filled with vibro-claying gel. Cable cost 15 000 c.u.!
XLO Electric(USA). “Empty litz wire” at the sight of several coils wound on a tubular base in two spirals (suvoro 90°), individually insulated middle conductors (interconnection and digital (!) cables), the great litz wire of the great total cut like acoustic cables. Expensive models have teflon insulation. Expressions of sound handwriting, which manifests itself in wine clarity and garniy detail.
Ultralink(Canada). A young company, to achieve success in the local and world market. The products do not have zahmarnyh prices, but at the same time, it is yakish. Vikoristovuetsya bezkisneva mid "six nines" of special technology for rolling, like dielectric teflon and nitrogen-filled polyethylene. There are also original spring RCA-lugs that guarantee good contact for a long time. Recently firm Ultralink priddbala famous american XLO Electric from the right to name the brand name of the rest.
Chord(Great Britain). The company that produces impersonal miracle cables seeks not just the best materials and constructive solutions, but also the optimal combinations. So, for example, a trail was installed in the distance, “Srіblo plus Teflon” and “Medium plus polyethylene spin.” Interconnect cables series Signature wink a coaxial design, the outer screen is grounded from one side, or it may have a lot of visnovok from the "crocodile". Low-frequency noise is reduced slowly by closed "earth" circuits. Great respect is attached to the purity of metal.
MIT Transparent Cable(USA). Tw two miracle companies are worthy of those who secure their cables with passive correctors of reactive parameters (sustainability and inductance), placed in boxes that hang on the cable. Great achievements and instrumental modification lead to the approved optimization of the cable, without changing the linear inductance and capacitance for any price, as usual. For a thought MIT For a short transmission of tension, the acoustic cable is responsible for the mother of the whole system and mutually related to the magnitude of the reactive parameters. Transparent Cable also actively fights against noise that is aimed at the cable (like an antenna) for the help of its filter-correctors. The products of both companies are correct. 
Audio note(Japan, UK). The cult nature of the products Audio note the world is expanding and cables. The remains are breathtakingly simple construction, often victorious with silver. You can see the stench of them, that it is a dielectric of polyurethane stagnation. The most expensive Japanese models Audio note The best chance is covered with polyurethane balls right at the last stage of rolling, practically including contact with repetitions (when the flooring is more stable and not oxidized, like mid). Deyakі models vygotovlyayutsya at the sight of litzendrate.
nordost(Great Britain). Additional interest is expressed by the lines of flat inter-unit and acoustic cables made of acid-free midi and slab. Dielectric - stamping teflon. Conductors of a straight cut (a few pieces for a straight line and a straight line) go strictly parallel and in the same plane. Tse minіmіzuє reactive warehouses. Tsіkavo, scho running capacitance and inductance is directed by the company on the skin model of the cable. Obviously, the capacity of such a configuration is minimal.
Goertz(USA). Composite flat copper cables with polypropylene dielectric. In contrast to the models nordost, A direct and virtuous conductor are superimposed one on one with a "sandwich", generating (when reaching a wide folzy) God knows how єmnіst! For the sake of this drive, the company may have its own idea: the linear capacity of changing the characteristic opir, similar to that, in such a rank, to the standard 8 ohms (input opir) is great acoustic systems). The theory is more complicated: the external opir pіdsilyuvachіv is more distant in terms of its value, and the speaker impedance lies in frequency. But practice in this way overrides the theory: with garniy stikovtsі z pіdsilyuvachem and columns of cables Goertz zdatni priemno zdivuvati navіt svіdchennogo audiofila.
Cardas(USA). One of the most aristocratic cable companies that successfully enforces the golden line principle in its retail outlets. The litz wire is made up of medium conductors of different diameters, which step by step changes to the center at the golden edge. Isolation from backed Teflon. Including electromechanical resonances and, as a hardening agent, improving other characteristics of the cable, zocrema, allowing reaching a stable electrical quality factor. Traditional cables Cardas win the most important assessments of experts.
stereovox(USA). Tse is the pinnacle of cable art. Krіs Sommovіgo, the retailer of that head of the company, having gained popularity on the cob of the 90s, the start of the revolutionary digital cable Black Orchid. Tsyogorіchna produktsiya vіdrіznyаєєmasoy іnnovatsіy. For example, srіbnі conductors of elіpticheskogo perezu in bagatosharovіy іizolatsії z backed teflon honed screen z veins, scho to go in parallel (interblockers). In acoustic drots, silver copper wire is stagnant. The tips of the original design are soldered with a silver-containing solder, the stock of which is hard to standardize. Behind the razdіlnoy building and the transparency of the cable stereovox turn over best models other companies.
Nasamkinets dodamo, scho cable, navit merezhevy, no doubt, є povnotsіnnym component of the audio system. Evidently, you need to give an hour for “earnings” and connect it exactly directly (sound it to be indicated by arrows or it is experimentally indicated). Underestimate the role of the cable - it means to allow your fine-tuning system. Cables are connected individually, like a bed is selected to a full dress.
However, there are serious defects, for example, obvious flaws in the tonal balance, the cable is not correct, but it is not an equalizer. The cables have a lot of their own sores, so that the stench could successfully excite strangers!
As a rule, the connection between a DVD-programmer and a receiver is connected according to digital channels, optical or coaxial cable The signal goes to the 6-channel decoder of the receiver and... If you use a proper decoder, a programmable decoder, or if your system has a sound source (for example, CD, MD), then, no doubt, you will need low-frequency cables.
Opening the box.
Weeders often complete their machines with such cables, such cables can be bought in commercial outlets. Wine with a thin screened dart with "tulip" roses in a plastic case (often indiscriminate) at the ends.
Such a cable is more than a garnier, so that it can be changed at the practicality of the device, and even more. The sound of the wines is driven in cleanly, if you want to connect the channel to the TV, boombox or music center, you can try vikoristati. prote, shorter solution- deprive them from the box of the apparatus and put it on the mezzanine, so that when selling this apparatus in the future, transfer it to the next successful vlasnik. The virobniks do not have to envy the versatility of their equipment, so in the kit, you can find the found primitive cable. Otzhe, our way to lie at the store.
We buy a cable.
Let's look into a store that sells cables more seriously. First of all, pay our respect - it's worth it for inexpensive cables from Vivanco and Hama. Similar cables in boxes with the inscriptions Video, Audio and audio gold look like three solid thin cords in the packages of devices. And the axis and the shelving with "Monsters" and "Audiolinks", a thick cable, metal roses, ale tsіni, tsіni ... It's hard to beat the spirit of the skin to buy a cable for a price of 50 - 100 $ per pair. Even if a decoder plugged into the program is connected, three pairs of cables are required. The glance turns to the counter from Hama, looks not so shifty, but the prices are richly lower. Only plastic cases of roses are indistinct.

Axis here and come and tell me about those that happened to be trimmed in the hands of a soldering iron, and maybe those that are expensive to buy, you can do it yourself. The audiophile store dazzles us with barvy boxes of roses and reels of cables. At a closer look, it’s obvious that you won’t win a lot of pennies. It is obvious that it is cheaper to complete the cable for the finished one, but the price is not as great as it should be. Get to compromise.
Compromise.
Guess, not only audiophile companies produce cables with good parameters and gold-plated roses. A sharp decrease in the price of mass production. Guessed? Our way to lie at the store comp. components ... bathe roses. We go to the trading house Bury Vedmіd. Catalog of goods, group: roses, type: audio - axis vin "RCA plug (tulip) for gold-plated teflon cable (RPC-3GT) (K29320T) Vyrobnik: Taiwan. Code: 220034 Price: 1.44 $ ".

Single "ale" - pin assignments for coaxial cable. Also, the first interconnect cable is miraculously coaxial in design.
Coaxial interblock cable.
For a number of reasons, for vibrating the cable "SAT 703b gas injected" 75 ohm (production of Italy), which occurs in receiving systems satellite television. There is a central mid-wire monocore, another spinning dielectric, underwire screening (braided and foil), low signal damping in smooth frequencies up to a gigahertz - indescribable brightness for an interconnector. The cable diameter is 6 mm, the cable should be thick and not like sharp bends. The soldering is more symmetrical on both ends of the cable, for soldering the vicorist, soldering with a small amount of slab.
We prepared the cables for the winding 0.6, 1.0, 1.5 and 2 meters. There were no differences between them in electrical parameters and sounding accessible methods. At the same time, the plan was to win the roses for a non-coaxial cable.
Interblock cable - kitty.
For preparation, we will twist the computer cable "twisted pair of category 5". Vіn revenge 8 medium conductors in insulation, twisted in pairs. Knowing the call of isolation and spreading twisted bets, not twisting them. The required amount of wires for the cable is about 4 lengths of the required inter-unit cable (8 lengths per pair). It is possible to win bets on 3 equal parts and collect in jguti for colors (3 red-white bets, 3 green-white bets and 3 blue-white bets). Crossing the jGUTI KISKOY I Nadyaga, on the kinzi shmatki of the Cambrika Vidpovydnaya Divzhino 3-5cm (setting the shmatki shells of the cable Sat 703), the instrumental of the tsoma, the puppy pi-ili in the middle of the jaguta, and the Paris dovkol.
For example, near the center - green, red and blue - along the edge. Solder green conductors to the central contact of the tulip, and red and blue conductors to the outer contact. On the prolonging end of the cable, only 2 bundles (green and blue) are soldered to the rose, and the darts of the red bundle are simply three times shorter and completely unplugged. The straightening cable, end, two bundles arrive, connect to the dzherel, and the one, de three, until the signal is received.
The length of the inter-unit cables in my view was 0.6 meters. Father, we may have material for a match.
Let's do it.
For the purpose of repair, "slip" tests were carried out on two sets of equipment. Pioneer PD-S605 and Micromega Minimum CD encoders served as the source signal, and Pioneer A-303R and Harman/Kardon 2.0 encoders served as the signal. It should be noted that despite the cheap set of Pioneer cables, the difference in sounding cables of both designs was practically not considered, and became clearly marked on the more expensive set of equipment. Here the "kiska" obviously overdid the coax, although it did not "reach out" to the expensive "Kimber" cable of a similar design, taken for equalization. On both sets of equipment obidva self-contained cables easily outplayed inexpensive Hama products.
Slid to bending, Parametry Kabeliv, Vicoristans for the vicobeum of the MIZHLBOVKIV, I can strongly get in the deposit of the Party, especially for twisted, the guarantor of the reckoning of the Schmatkiv cademan of the Bobini, cornfields in the corner of the bubble As soon as possible, prepare the necessary amount of cable for all interconnects, even for connecting a DVD player with a decoder. You may need up to 8 of these cables.
We also prepared cables from other coaxial cables (for computer system 50 and 98 ohm), and with a different number of twisted pairs at the bundle of pussy. Description of construction here (coaxial cable SAT 703 and kit 3 twisted bets at jguti - 6 signal conductors, 6 earth conductors and 6 screen conductors), showed best results in their classes.
