The most popular audio cable types are known as RCA connections. These are usually the cables with black and red, or even yellow and green connectors. RCA connections are very commonly used to link electronic devices such as VCRs or DVD players to home television sets or CD players. They are also used for connecting microphones and speakers to powered electronic equipment. In fact, RCA is one of the most recognizable brands in audio-video electronics.
The most popular RCA audio cable is made by the RCA Corporation. It is often used for connecting speakers to the front of a stereo system. There are two different styles of RCA connectors. One style uses gold contacts on each end of the audio cable, and another style uses copper contacts. The type of contacts determines the polarity of the signal that the cable will carry. Gold contacts send high voltage signals, while copper contacts carry low voltage signals.
Audio cables that are RCA compatible can be used for many different applications. For example, they are commonly used to connect microphones to the front of home theater systems. Home theater systems often have a microphone preamp that is included in the system. Audio cables used for this application can be easily connected to RCA adapters to allow the microphone to be operated from a separate location, without affecting the sound quality of the audio source.
Another use for RCA cords is to connect power cords to extension cords. Power cords are commonly used in home offices to provide extra power to computers and other electronic devices. Audio cables designed for this purpose make it possible to run the cord through walls and into room dividers, to avoid any interference with the main system. Audio cables that are RCA compatible are perfect for this application because the signal is able to flow seamlessly between the wall outlets and the speakers.
A final application for RCA audio cables is to connect a tape deck, stereo system or computer to a multi-amp device. Some multi-amps have their own output jacks, so connecting the audio cable directly to the unit is not practical. Instead, an RCA auxiliary input jack can be used. These types of auxiliary outputs connect a device to its corresponding speakers or mixer. The advantage to using an RCA auxiliary input jack is that it provides extra wiring options and does not require a specific wire size.
When purchasing a RCA cable to connect multiple gear, you need to make sure the cables will not be susceptible to interference. Since there are so many types of RCA connectors, it is difficult to estimate which connectors will give you the best performance in terms of elimination of interference. Manufacturers recommend using a connection sleeve to shield the connection between the audio cable and the amplifier. This keeps the RCA connector free from interference so it functions well with multiple devices.
The cables available for the iPod, CD player and other popular music devices often have short and long cable lengths to match the specifications of the device it is intended to support. Most iPod cables, for example, are approximately 18 inches in length and are intended to support the high volume playback required by the iPod. Longer iPod cables, on the other hand, are typically needed to handle the constant audio data coming from the various speakers used with the iPod. The typical long-iPod cable will also have several connections and ground loops to handle all of the wiring involved with multiple iPod accessories.
Audio cables come in different sizes and colors to meet the needs of a wide range of customers. Most cables are sold by the manufacturer as either pre-packaged units or with individual connectors, making it easy for customers to select the perfect cables for their needs. If a customer needs multiple cables and wants them delivered in one package, most major electronic stores will accommodate them. Many online retailers, however, offer high-quality cables at discount prices. In addition, many online stores offer free shipping and pay for any engraving or delivery work that customers may need.
