TS Phone Connector
Tip
These jacks also can be connected with TS phone connectors. If you use TS phone connectors, the connection will be unbalanced.
Connector Types
XLR
This 3-pin connector is resistant to externally induced noise, and is used primarily for balanced connections. With properly designed receiving circuitry, cables with this type of connector can also be used for unbalanced signals.
XLR type connectors are the standard for microphone connections as well as most professional audio gear.
Male
Female
Phone
Phone connectors are available in TRS and TS types. TRS types are used for stereo headphone jacks, insert jacks, and also for carrying balanced signals in many cases. TS types are used to carry unbalanced signals -for example, electric guitar cables.
RCA Pin
This type of unbalanced connector is most commonly found on home audio and video equipment. RCA type pin jacks are often color coded: white for left audio channel and red for right audio channel, for example.
