Types of Audio Cable
"A sound is a wave traveling through solid, liquid, or gas. For it to be audible, it needs to have a pressure of 20 micropascals, or it needs to be at 1,000 Hz. Anything below that can still be heard, but you will need the help of an audio device. Hearing it is made possible by audio cables. Audio cables are wires that transmit audio signals. Here are some types of audio cable.
- 3.5mm Audio cables. The 3.5 audio connector was originally designed to be used for small transistor-based radio receiver earpieces. It is also known as an audio, stereo, mini, or mp3 jack, or phone or jack plug. It is commonly used in headphones or earphones. 3.5mm audio cables used in microphones are usually called splitters.
- Digital Audio-Toslink Cables. Toshiba designed the Toslink or optical cable, mainly to be used for their CD players. It uses glass or plastic fiber for its connection system. It can be used up to a maximum of 5 to 10 meters without using a signal booster. It is commonly used in Mini Disk or CD players, or digital audio tape recorders.
- RCA Stereo Audio Cables. The RCA (Radio Corporation of America) stereo audio cable was originally designed for amplifiers to be connected to mono phonograph players. It is also used as a video cable. Its disadvantages compared to other types of audio cable is that each signal needs a separate plug, and that there are audio devices that need an adapter, along with the RCA cable, to work. Therefore making it more complex to be used. The RCA stereo audio cable is also known as phono or Cinch connector. It is commonly used for power connection as an extension cable or for cable testers, for RF connection, and for speakers or televisions
- SubWoofer Cables. A sub woofer cable is a connector that is used for loudspeakers. This speaker cable can transmit anything from 150Hz and below. It is used for amplification, equalization, phase control, and feedback of audio signals.
- Digital Audio - S/PDIF Cables. The S/PDIF cable or Sony/Philips Digital Interconnect Format cable is used to transmit stereo digital signals. It is commonly used in sound cards for computers, CD or DVD players, or car audio systems
- Pro-Audio Cables (XLR, TRS). The XLR cable, designed by the company Cannon Electric, is used to transmit audio signals for high quality microphones, or to transmit musical instrument digital interface data. It is normally used in recording studios because of its reliability in sound quality even if used in great lengths, and it reduces external noise. The TRS (tip, ring, sleeve) cable is a connector that was originally designed for telephone switchboards in the 1900s. It has 3 types: 1/4" (6.3mm), 1/8" (3.5mm), and 3/32" (2.5mm). It is commonly used in headphones or earphones, microphones, personal computers, electric guitars, instrument amplifiers, electronic keyboards, electronic drums, modular synthesizers, or CCTVs.
Most electronic devices use audio cables. It lets you hear things that are not audible to the human ear. Without it, life would be a bit boring. Imagine not being able to listen to recordings. You may not know it, but it is already a part of everyday life."
