Audio Cables
Audio cables are used to connect audio equipment such as hi-fi’s, home cinema equipment or even instruments to an audio output. They are available with a wide variety of connectors depending on the equipment they are used with, the sound quality required and whether the audio signal is digital or analogue.
For Home Cinema, professional audio and hi-fi installation, digital connections are often used. The most common digital audio interface is known as SPDIF (Sony-Philips Digital Interface Format). The SPDIF interface can be implemented in two different ways: coaxial and optical. The coaxial SPDIF interface uses RCA phono connectors and 75 Ohm coaxial cable. The optical interface uses fibre optic cable with either TosLink or Mini Optical connectors.
Mini-optical connectors are sometimes called Mini-Toslink, MiniPlug or Mini Optical jacks, but they all refer to the same connector. The mini-optical connector is typically used on portable CD and MD players, but it is also used on other audio devices. The TosLink connector is commonly used on DVD and CD players, DAT recorders, surround sound receivers etc.
Common analogue audio cables include phono cables for connecting Hi-Fi and AV equipment; XLR cables which are used in pro audio and music applications; musical instrument cables which feature 6.5mm jack plugs, and general purpose audio connection cables with 3.5mm jacks.
