From Wikipedia, the free encyclopedia
An Audio connector is an electrical connector for carrying an audio signal in analog or digital format. Analog audio connectors often use Shielded cable to inhibit RF interference and noise.

[edit] Audio Only
- Single-conductor connectors:
- Banana connectors
- Five-way binding posts and banana plugs for loudspeakers
- Fahnestock clips on early breadboard radio receivers.
- Multi-conductor connectors:
- DB25 is for multi-track recording and other multi-channel audio, analog or digital
- DIN connectors and mini-DIN connectors
- RCA connectors, also known as phono connectors or phono plugs, used for analog or digital audio or analog video
- Speakon connectors by Neutrik for loudspeakers
- TRS connector also known as tip-ring-sleeve plug, phone plug, jack plug, mini-jack, and mini-stereo. This includes the original 6.35mm (quarter inch) jack and the more recent 3.5mm (miniature or 1/8th inch) and 2.5mm (subminiature) jacks, both mono and stereo (balanced) versions.
- XLR connectors, also known as Cannon plugs, used for analog or digital balanced audio with a balanced line
- Digital audio interfaces and interconnects:
- ADAT interface (DB25)
- AES/EBU interface, normally with XLR connectors
- S/PDIF, either over electrical coaxial cable (with RCA jacks) or optical fiber (TOSLINK).
[edit] Audio and Video
Some connectors can carry both audio and video signals simultaneously:
- DisplayPort digital connector
- Unified Display Interface (UDI)
- F connectors are used with RF modulators for televisions without direct inputs
- HDMI is a new digital standard
- SCART, now the most common in Europe
- TRS connectors with more than one ring, or Sony's hybrid RCA with a TRS pin
- Coaxial cable/RG-6/RG-59/Cable television (CATV)
[edit] Color Codes
white RCA/TS | analogue audio, left channel; also mono (RCA/TS), stereo (TRS only), or undefined/other |
black RCA/TS/TRS | |
grey RCA/TS/TRS | |
red RCA/TS | analogue audio, right channel |
orange RCA | SPDIF digital audio |
For computers:
green TRS 3.5mm | stereo output, front channels |
black TRS 3.5mm | stereo output, rear channels |
grey TRS 3.5mm | stereo output, side channels |
gold TRS 3.5mm | dual output, center and subwoofer |
blue TRS 3.5mm | stereo input, line level |
pink TS 3.5mm | mono microphone input |
There are exceptions to the above:
- Hosa cables use grey and orange for left and right analogue channels.
- RadioShack cables sometimes use grey and black for left and right.
- Older sound cards had non-standard colour codes until after PC99, prior to that there were no colours at all.
