2. TRS Cables: These cables come with a tip-ring-sleeve ( TRS) connector on each end, and they are used for balanced audio connections between various equipment such as direct boxes, mixers, and effects processors. TRS cables help reduce common-mode interference and improve noise rejection.
3. TS Cables: These cables use a tip-sleeve ( TS) connector on each end and are used for
