When it comes to audio cables, there are several brands and types available, with the choice depending on what you are trying to hook up and how concerned you are with the quality of the sound. In general 5-7% of total cost is adequate for investing in the cables for the system. If you are not terribly concerned with sound quality and are just listening to things like news and music in the background then you can use pretty much any cable, even the cheap one packaged with your 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 basic purpose of a cable is to transfer the signal from point A to point B unadulterated. At audio frequencies the goal is to minimize losses by controlling the amount of Resistance, Inductance and Capacitance. There are four basic kinds of cables that one can use which are analog audio cables, audio video cables, audio speaker cable and digital cables.
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 critical cables since the signals that pass through them are at very high frequencies. The higher it is, the more critical to have a proper impedance, proper shielding and good teminations that audio-video cables should provide. So, a video cable must be well shielded and must keep the proper typical impedances.
Audio Speaker cables are generally quite thick, with two conductors. At the tip they may be tipped with metal pins, banana plugs, spade plugs, or even just bare wire. When connecting it is necessary to ensure closest and tightest possible connection from cable to amp or loudspeaker in order to minimize contact resistance. It is also important to remember that the speaker cable runs should be kept as short as possible and not to loop excess cable as it can potentially increase cable inductance.
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.
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 cables, analog ones and digital cables.
