Audio/Connector/Phone/TS

• TS — Tip-Sleeve

  • Two contacts, one insulating ring. The tip carries a single unbalanced signal; the sleeve is its ground return.
  • The oldest of the phone layouts, descended from the 19th-century telephone switchboard plug.

  • Sizes

    • Audio/Connector/Phone/TS/3.5mm — mono earpieces, and patch points on compact gear such as modular synthesizers.
    • 6.35 mm (1/4 in) — the full-sized original: electric guitars, amplifiers and effects pedals.
