Tip Ring Sleeve ('''TRS''') Connector s are three-conductor Jack Plug s and the corresponding sockets, used in many Stereophonic and other Audio applications. TERMINOLOGY The term is associated with Telephone usage. In Twisted Pair wiring to this day, the non-inverting and/or "live" wire of each pair is known as the ring, while the inverting and/or "earthy" wire is known as the '''tip'''. If the pair is shielded, or if the pair is accompanied by a dedicated earth wire, this third conductor is known as the '''sleeve'''. This usage corresponds to the connection to a three-connector jack plug in a manual telephone exchange. This appears to have originated with the use of '''TRS''' jacks by Switchboard Operators with the ''tip'' and ''ring'' wires attached to the corresponding parts of the jack. Originally, the ''hot'' and ''ground'' were reversed, but often the metallic desktops of the switch boards were scarred by the discharge from the tips and the system was reversed to the present usage. The term tip ring sleeve is more common in some English-speaking countries than others. Outside of the USA the term ''stereo jack plug'' is probably more common, even for connectors not used for stereo. The modern profile three-conductor jack plug was originally designed for stereo signal connections, with left channel on the tip, right on the ring and common return on the body or sleeve. The term '''TRS''' is particularly appropriate to distinguish these three-conductor (stereo) plugs used in other than stereo applications. | ||
