T.R.S.

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:

1. The "tip" which is the conductor at the tip of the plug
2. The "ring" which is the middle conductor
3. The "sleeve" which is the longest conductor furthest from the tip.
