1/4" Tip-Sleeve Connectors

1/4" tip-sleeve (TS) connectors (also called 1/4" phone connectors) with a tip and a

sleeve are unbalanced connectors often used for musical instruments like electric

guitars, keyboards, amplifiers, and so on.

1/4" Tip-Ring-Sleeve Connectors

Professional equipment often uses 1/4" tip-ring-sleeve (TRS) audio connectors with

+4 dBu line level. 1/4" TRS connectors connect to three wires in an audio cable—hot,

neutral, and ground—and usually carry a balanced audio signal. In some situations, the

three wires may be used to send left and right (stereo) signals, making the signals

unbalanced.

Note: Tip-sleeve and tip-ring-sleeve connectors look almost identical. Some audio

devices (especially mixers) accept a TS connector in a TRS jack, but you should always

check the equipment documentation to be sure. Remember that most 1/4" TS

connectors connect to –10 dBV line level equipment, whereas 1/4" TRS connectors

usually expect a +4 dBu line level.

XLR Connectors

These are the most common professional audio connectors. They almost always carry

a balanced signal. Many cables use an XLR connector on one end and a 1/4" TRS

connector on the other. The signal may be microphone level (when using a

microphone) or +4 dBu/dBm (professional) line level.
