1/4-Inch Audio
1/4-inch connectors (sometimes called phono or phone plugs) are used on a wide
variety of professional and consumer musical equipment, including musical
instruments and amplifiers, speakers, and external effects devices. They can be either
balanced or unbalanced. Some devices require Tip-Ring-Sleeve (TRS) connectors. These
three-contact connectors are used for balanced mono signals and unbalanced stereo
signals.
1/8-Inch Miniplug
Miniplug connectors are used for audio input and output to computers, and on some
consumer electronic devices, particularly portable ones.
RCA (Cinch)
RCA connectors are used on consumer audio equipment such as home stereo systems
and videocassette recorders.
AES/EBU, S/PDIF, and ADAT
The AES/EBU, S/PDIF, and ADAT protocols provide a digital connection between
professional and consumer audio equipment, including audio interfaces, DAT (digital
audio tape) machines, mixing consoles, hardware samplers, and more.
S/PDIF and AES/EBU provide two channels of audio, and ADAT optical provides eight
channels of audio. You can use optical TOSLINK connectors to carry digital audio
streams between S/PDIF and ADAT components.
