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.
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 may be the most important cables as the signals that are passed through these cables are at a very high frequency. The higher the frequency, more critical it is to have proper impedance, adequate shielding and solid terminations which audio video cables provide. Thus, a video cable should be well shielded and should maintain the proper characteristic impedance.
Audio Speaker cables are usually fairly thick, and have two conductors; they can be tipped with spade lugs, metal pins, banana plugs or just bare wire. One needs to ensure that there is the tightest connection of the cable to amp and loudspeaker to minimize contact resistance. One should always remember to keep the speaker cable runs as short as possible and not to loop excessive cables as this may slightly increase cable inductance.
Digital audio cables are a special group of their own. Of these there are two types: coaxial and optical. Coaxial digitals look just like standard analogs, but transfer digital audio rather than analog, while optical cables use light as a transmission method for audio signals. These types are also usually a single cable, where analog types are generally double plugs to stereo sound.
Depending on your choice of audio requirements for sound quality, there are a host of cables available in the market. Most general purpose users do not need to look at the brands and quality of cables and the cheapest ones that come packages with the equipment work fine. Choosier customers may have to spend several hundred dollars to satiate their high quality desires. The main objective of these specialized cables is to transmit audio signals from one point to another unchanged. This involves minimizing losses by controlling Resistance, Inductance and Capacities at audio frequencies. Various specialized audio cables include audio video cables, audio speaker cable, analog ones and digital cables.
