Overview
The term "T.R.S." is used to describe a three-conductor 1/4" "phone" plug similar to a headphone plug.
History
The T.R.S. connector was originally developed for use in telephone switchboards. It is widely used in audio applications for making balanced audio connections.
Basics
The T.R.S. connector is a 1/4" diameter "phone" plug that has three conductors:
- The "tip" which is the conductor at the tip of the plug.
- The "ring" which is the middle conductor.
- The "sleeve" which is the longest conductor furthest from the tip.
Typical Wiring Connections
- The tip is connected to the "high" signal conductor of the twisted pair, which may also be designated the "+" conductor as it will carry the non-inverted signal.
- The ring is connected to the "low" signal conductor of the twisted pair, which may also be designated the "-" conductor as it will carry the inverted signal.
- The sleeve is connected to the Shield.
In the vast majority of cases, a shielded twisted-pair cable is used for cables with T.R.S. connectors on one or both ends.
