Before buying audio cables you should determine whether you think sound quality is important to you. There are so many different cables available; you want to be sure to get the most suitable one that meets your specific needs. A certain amount of money, usually between 5 and 7 percent of the overall cost for the sound system, should be spent on good quality cables. If sound quality is not your priority, you might want to stick with the cables that were included with your sound system.
People who are more keenly interested in higher sound quality have more options. Cable specialists have products designed for increased quality and durability. Some of these cables can cost as much as five hundred dollars or more. While many people have trouble telling the difference between sound coming through the most expensive cables and through ordinary cables, there is an elite that believes that no price is too high when it comes to owning the very best equipment for the ultimate audio experience.
The four different types of cables are analog audio cables, audio video cables, audio speaker cable and digital cables. Their job is to move a signal from one point to another without unchanged. This is accomplished along with minimizing losses, through control of the amount of Resistance, Inductance and Capacitance at audio frequencies.
RCA connections are utilized for passing analog line-level audio signals that go between components. RCA audio cables come grouped in stereo pairs, one connection is for the right channel and one for the left audio channel. A good idea for line level analog interconnects is the use of a cable with the following qualities: well shielded to eliminate interference and external noise sources, and low in capacitance.
Video Cables are possibly the most important as the signal that is passed through is at a very high frequency. As the frequency increases it becomes more critical to ensure adequate shielding, solid terminations and proper impedance that audio video cables provide. Therefore it is necessary for a video cable to be adequately shielded and maintain characteristic impedance.
Audio speaker cables are normally quite thick and have two wires: they may be tipped using spade lugs, banana plug or simply bare wires. It is required to be sure that the connections are really tight to the amplifier and the loudspeakers to reduce contact resistance to a minimum. You should never forget to keep the speaker cables as short as possible and avoid looping cables too much since this may augment cable inductance slightly.
Audio cables come in two different types and are usually a single cable. The first type is an optical cable; it transmits digital audio signals as pulses of light. The second form is coaxial cables look like standard analog cables, but what they do is transfer digital audio signals.
Although there are many types of audio cables, expensive ones are not necessary if listening to background music and radio broadcasts etc. The job of the cable is to pass the signal from source to output minimizing any interference. Paired RCA cables, preferably low in capacitance and resistance should be used for line level analog interconnects. audio video cables should have adequate shielding as a high frequency signal is used. audio speaker cable needs to be secured tightly to ensure low contact resistance. Special digital cables are available namely, coaxial and optical which transmit light pulses and digital signals respectively.
