Insight into Speaker Cables

There are a lot of myths about speaker cables, but in the end it's thickness that counts, and 12 gauge should be heavy enough for any reasonable domestic application. I've taken several comparative listening sessions over the years, and the sort of cable you want to use involves no sonic degradation that I (or anybody else in the tests) could hear. You could even cable the whole distance from amp to speakers using 12-gauge, but it would probably be more convenient to use something more flexible for the actual connection to components. Specialty audiophile cables would serve that purpose nicely, although more modest cables would work just as well."

This cable at the right was sold as speaker cable several years ago by such places as Home Depot and Lowes. It sold for 33 cents/foot. It had transparent insulation and was 12-gauge. It was much less expensive than the brand names. It did not have any coding to identify one of the cables for proper phasing. I had some of this cable for about 6 months and noticed it was turning color. Now it has turned a very pronounced green on the surface of the copper cable, indicating a chemical interaction with the insulation and the copper. A new piece of cable is at the right for comparison. Although the cable may not corrode any further, it doesn't inspire confidence, particularly if the insulation comes close to the connecting terminals. Such audio cables are quite used in home theater speakers as well.

Perhaps the transparent insulation was an attempt to mimic the more expensive speaker cables. Without researching the chemical properties of the insulation or the need to code one of the cables, it was not well thought out for use as speaker cable. I have heard complaints by others about the same problems. The normal lighting cables and cable supplied with the receiver shown above do not have these problems. I still have some of the #16 lamp cord that was used at the shows back in the 1970’s and it still shows no sign of oxidation, corrosion or patina. Such cables find use in car speakers, car stereo systems and car amplifiers.

Use of Power Control Cables in Home Theater System

The main aim behind using a control cable is transmission control. In the various industrial, applications, including energy and transportation sector, generally, cables are widely being used.

The audio system consists of various components such as amplifiers which we will be discussing here in detail.

The cables provide basic source of signal transmission. The cables generally consist of copper which help in the alignment of its crystalline structure, and allow the electrons to flow in a natural direction. This helps in the pre-imposition of a preferred signal on the material itself which in turn allows improved transmission in home theater system in the right direction.

The cable will be working obviously, in opposite direction. That is why arrows are there on the connectors of these power control cables, which clearly indicate the most preferred direction of signal path for the peak performance of cable.

Every cable attenuates signals so it all depends on users to prevent such losses.

Speaker cables which are used in audio systems have lower resistance values whenever cross-section increases. The cables used are sometimes as short as possible.

For the cables which are being used in home theater systems, the frequency rise starts to deform the signal after 5 mtrs. If there is requirement for long distance cables then low impedance inverters are valuable.

The microphones used in home audio system generally have a low impedance value, so it will be a good solution to use star-quad cables in such special applications. So it makes the cable less sensitive to various electromagnetic interferences.

One of the most important things about use of power control cables in home theater system are:

• The installation of the cable wiring should be done properly to allow smooth signal transmission across them.
• The other advantage about these fine wires is to reduce noise effects.
• Another important electrical characteristic of cable is capacity. In reality, a cable works as a capacitor that, in series with the impedance or the signal source forms a low-pass filter, which significantly filters out the high end of an audio signal.
• If the installation of these cables is done properly then they help in proper functioning of all components of the audio system.
• So if you are want to make the audio sound perfect then the damping factor must be considered to reduce the distortions.

Home Theater Systems Key Tips

Prior to the launch of home theater systems, best way to watch a movie was to go to cinemas. Later on the VCRs were introduced which made it easy to rent or buy movies and watch them at home, but movie watching on TV should never be compared to huge screens of movie theater  and also the surround-sound systems. Actually as everyone knows TVs do have comparatively tiny screens and lower quality speakers, formatting a movie to fit the screen helps you to get rid of substantial part of picture.

These days many more people try to turn the ordinary TV rooms into home theater. This involves a projector and a screen, and it was too expensive for most people to afford. But as per the latest updates in high end audio technology more choices have been offered to people for home theater setups.

A proper home theater system set up needs many steps which are to be followed:

• One needs to prepare the room for installing this system. For those who have already spent much on home theater systems purchase do not want to spend on the room. The best option for them would be to go in for a rectangular room which has less number of doors.
•  Selecting components of the system is obviously a personal question. It depends on your requirement which component to go for either flat screen TV’s, CRT TV’s, HDTV or Plasma TV’s. Home theater speakers, receivers, video output and surround sound formats.
• Compiling each and every component of home theater system is also important. Actually the idea behind it is to create an exact replica of the movie theater at home and enjoying its effects.
• The speakers should always be mounted on stands or on wall. This will create great sound effect.
