1/4 in TRS Male

The 1/4 in TRS Male connector is a type of electrical connector primarily found on professional audio, video, and stage lighting equipment. The connector looks similar to a 1/4 in guitar/instrument cable.  You can tell the difference between a 1/4 in TRS cable and a 1/4 in TS (guitar/instrument cable) by the amount of lines on the metal sleeve.   A TRS cable has a tip, a ring, and a sleeve (so only 2 lines), whereas a TS cable only has a tip and a sleeve (only one line). TRS cables/connectors are most commonly associated with a balanced audio interconnection.

TRS outputs are generally always balanced, whether mic or line level. Balanced audio is a method of interconnecting audio equipment using balanced lines. This type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference.

Balanced connections typically use shielded twisted-pair cable and three-conductor connectors. The connectors are usually three-pin XLR or 1⁄4 inch (6.35 mm) TRS phone connectors. When used in this manner, each cable carries one channel, therefore stereo audio (for example) would require two of them.
