instrument cable and a good construction

If the mixer can be an assumption as the heart of the system, the cable can be assumed as intravenously. Poor quality cables will reduce kulitas audio for the entire system. Nothing can turn the importance of how a cable system in the audio. Various sound company is certainly very large understand it. An instrument cable can be a good show soudstage the image of deep and high, with a high resolution, detail, timbre that is super, natural tonal balance and very neutral. USB-cable ii tonally not colored, and is compatible with many systems aplifier, speaker and pre-amp. We know many conventional cable design has the look that good physically, but does not survive long, because the conductor is thin. Umu shortage of this type of cable is a weak focus and image resolution. Some cable-this is to combine a high resolution of informai, transparency, and focus on the three-dimensional image with a neutral tonal balance and warm.
Construction in the cable
Here we will identify the configuration koaksial (co-axial) and twin axial. Koaksial, this configuration is used for regular cable unbalans instrument. There are conductor (penghantar signal) or the center conductor. Responsible for carrying electric current or signals from the source (source) and disekat by insulation material that separates the conductor from other parts of the earlier dalm cable, ie, shield (scutum). Shield is also a conductor, but a conductor pengembali electric current or signals to melngkapi flow into a circuit.
Before the third component (conductor, shield and the bulkhead) equipped with two arms, in the form of a shield elektrostatis who work to reduce handling noise level. Then, outside the protective / outer cable jacket to protect against the "outside world", and used to beautify the view cable.

Koaksial VS Twin Koaksial
Koaksial a different cable and twin koaksial, koaksial using an isolated conductor is at the middle to bring the voltage signal, as in the shield. Here the shield connected to the contact to "negative" from the plug on both ends, while the conductor in the middle of the contact "negative". Because the analog audio signal is a flow back and forth (alternate current), the signal volatse positive and negative bergonta-change in the central conductor and shield.

While cable koaksial twin (twin-ax) two conductor isolated from the voltage signal that is surrounded by a shield that separate. In this case, the shield to be placed one end of the cable conductor and acts as "negative." Shield is designed to block the entrance to interfensi conductor with the audio signal, as well as to bring interfensi (hnya) sasis to the ground from the device that is being used. Design twin-ax is generally more costly rather koaksial. Especially when the cleaning process for the audio signal path, and to avoid any ground loops.

Relationship between the materials in the cable
Refers to the relationship between conductor and shield layers or protectit (read: shield). Geometrical effect of different akan elektrikal and characteristics to the shielding of a cable, which in turn affect the tmpilan vote. There are two approaches in terms of design that can be made to the overall geometrical instruments for cable, that is, the design of co-axial and twin-axial.
Shield is responsible to bring half of the audio signal. So, perforce, this shield must be able to maintain the conductor cable from the interfensi possible to route signals from outside the device (such as the amplifier or console), that is, to the ground.

Conductor geometry
In a twin-ax design, pattern, relationship between the conductor and the shield will affect the characteristics of a cable elektrikal. For cable, the most relevant characteristics related to the second factor above is kapasitansi and induktansi. Kapasitansi effect of this can be heard clearly in an instrument cable. Kapasitansi is often measured in units of dngan Pico farad per foot of cable. From a two-conductor cable dipararelkan, this cable will have a relatively high induktansi and kapasitansi low, and more can pick up mem-interfensi. Braid type conductor kapasitansi tend to show high induktansi with a lower and vulnerable to noise.

Cable located in the instrument under the jacket around the outside of the dn signal conductor is usually a form of foil, braid, or a combination of both. Shild foil have a power of good protection against interfensi high frequency, such as RFI (Radio Frequency Interference).
Shield braid are more effective against all forms of interference that is now there, if the shield is in-woven with a sufficient density. Shield uses a lot of copper.
A shield can have a spiral density is higher compared to the braided shield, but less flexible than braid. Shild spiral membka and this can provide a path for interfensi, if the cable is too often be bent or lekukkan. Look for cables that use a shild braided (atai combination of braid and foil) with a density range of at least about 85%.

Have a direct influence on the flexibility of a cable, especially for the size and thick tipisnya material. Beinsulas a conductor, the characters actually have not ubahnya as a solid conductor. The thin insulation, the cable is more flexible.
There are criteria for elektrikal this flimsiness insulation. Called "Dielectric Strength", and the voltage levels determined by the work of the cable. Voltage is the use of cable dalm instruments generally very low, so that the level of dielectric strength is needed to prevent insulation anjlok not very small.
There is one factor to consider, when the cable will be used for instruments such as electric guitar, that is, the number of kapasitansi between the middle conductor (center conductor) with a shield.
On the insulation material, there are essentially four insolator material that we know for a conductor in the instrument cable. Can be mentioned here, according to the sequence level and display a higher price, ie, PVC, Polypropylene, polythylene and teflon. The material can be also in the "Foam" or diinjeksi with air to minimize the bad effects of the signal, while the signal is stored or removed.
The process is known insultasi Thermoplastic more ekoomis, but need to be careful in the process of production. This is because the process can not be pemanasannya excess heat (overheated), especially when penyolderan isolate conductor.

Material conductor
Ah copper (copper) conductor is material which is very good, although not all have the quality of the copper as conductor material. Copper is used in a cable of good quality, with levels ranging from the free oxygen to "7N". This type of copper vary in the level kemurniannya who then referred to as the level Percentage of copper. At the end of the spectrum is a copper "7N" which means "seven nine", after the decimal point in value kemurniannya, ie, 99.9999999% pure.
While the materials used for the center conductor may be made from thermoset materials, ie, curry, neoprene, and hypalon. Can also of thermoplastic material which is, namely polyethylene, Polypropylene, PVC, and the FPE.
Silver or silver is also a good conductor, but subjective differences in silver made by the manufacturer, often greater than the difference in copper. Look for cables that use a minimum of OFHC copper conductor, and try each of the cable conductor using copper bersepuh silvery, before you buy.

Conductor design
Source of distortion in the other cable is the interaction that emerged from the strand-strand (strand) in the cable conductor. Strand-strand is made in order to increase flexibility in the cable. However, each strand in a union will bring the same audio signal dngan strand next to it. Akan problems arise, the current balance sheet berjlan dlam will form a magnetic field., Who brought the signal change. The strand that many dimilkiki by a conductor, it will be more problems that arise.

Is the factor of interest in a cable. Kapasitansi ability level is a load electricity. In an instrument cable, kapasitansi between the center conductor and shield, is expressed in units per foot (pf / ft). Where is the more low-value, then on the more low berindikasi also kapasitansi. When combined with Impedance source, cable kapasitansi can form a low-pass filter between instrument and amplifier, which can cut the high frequency cut off at the way the tone control instruments.
With the view that the overall outside diameter of the cable is limited by the need to use plug, cable kapasitansi really is a reflection kombiasi between the size of conductor (power conductor), insulation material (cost), and tenuity insulation (the size and flexibility). The term "Dielectric constant" is often used here to see the quality of the insulation material. Of course this will ultimately determine sound clarity.

There is no cable is truly perfect / can improve the sound of our device. There is only a cable that can keep the audio signals from the things that can reduce the purity.
