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 want improved sound quality for listening can find something in their price range from cable specialists. Specialized cables provide optimum sound quality and are very sturdy. These are a better alternative to generic speaker cables which offer lower sound quality and aren’t as sturdy. Although the specialized cables may be affordable, the cost still could be several hundred dollars for the speaker cables or analog audio interconnects. Some people may find that the extra money spent is well worth the benefits of better sound and pride in owning the very best in audio equipment.
Analog audio cables, audio video cables, audio speaker cable and digital cables are the four basic types of cables that can be used to transfer sound. These cables transfer the audio signal from point A to point B unaltered. You control the amount of Resistance, Inductance, and Capacitance thereby minimizing losses at audio frequencies.
To pass analogue line level audio signal between components, RCA connections are employed. RCA audio cables are joined in stereo couples, with a connection for the right channel and one for the right channel of audio. For line level analogue connections it is a good idea to employ cables which have low capacitance and properly shielded to avoid interferences and external noises from getting to mix to the signal.
The most important cables are video cables as very high frequency signals travel through them. Audio video cables provide proper impedance, adequate shielding and solid terminations found with high frequency, and the right type of cable can be critical. So the shielding and maintenance of the proper characteristic impedance need to be aspects of a video cable.
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.
Good quality audio cables generally cost around 7% of the total audio system cost and can be chosen from several brands. They can be categorized as analog cables, audio video cables, audio speaker cable and digital cables. Analog cable uses RCA connectors that come in stereo pairs for left and right channels. Video cable carries signals at a very high frequency while speaker cables are generally thicker and have two wires. They should connect to speakers and amplifiers with least contact resistance and should be as short as possible. Digital cables can be either optical or coaxial and carry audio signals in digital form.
