An audio cable is a wire that transmits and receives audio signals from a sound-generating device to a receiver. Audio cables are essentially thin internal wiring systems covered by outer layers or shield of twisted or woven foil. The outer layer is designed to pick up unwanted hums and buzzes before they reach the audio signal to produce a clearer sound.
An interconnect audio cable is designed to connect an MP3 player to a speaker or a stereo component to a receiver. It uses a little energy to transmit signal from a source to a receiver. The signal has very little current only. Interconnect Audio Cables are further classified into two subtypes: analog and digital. An analog audio interconnect cable comes in pairs. It is commonly tipped with an RCA cable connector. A digital audio interconnect cable comes in an optical or coaxial type.
Audio speaker cables
An audio speaker cable is designed to connect the amplifier or receiver to speakers. It carries a large amount of energy required for moving the speaker cones and producing sound. The signal it transmits has a high current, usually reaching 10 amps or more. Audio speaker cables are thick cables with two conductors on one end. They can be easily tipped with metal pins, spade lugs, or bare wires.
Conductor construction: Choose an audio cable with a solid center conductor. This type of conductor is ideal for permanent installation, limiting the cable movement and reducing the stress caused by flexing. For flexibility, look for an audio cable with a stranded center conductor, allowing more flex and offering longer flex life. This type of audio cable is suitable for portable or temporary use.
