In the BlueRoom context, TRS may have two definitions. Fortunately, it is generally obvious which one applies :)
- TRS, in the context of power cables, is an acronym for tough rubber sheath and is frequently incorrectly used to refer to H07RNF which is in fact sheathed in polychloroprene (Neoprene). TRS was also referred to as cab-tyre sheathed or CTS. The use of rubber as a sheath has now almost completely given way to more modern materials however it is still used as insulation where greater flexibility and heat resistance than that of PVC is required.
- TRS, in an audio context, may refer to a Tip Ring Sleeve jack plug, which is commonly used for balanced audio, or stereo, or Insert Leads.
