What are jacks and plugs and what are they used for?
Jacks and plugs are mainly used for the transmission of line signals (0.775 V). The most important application is the connection of guitars, keyboards, headphones etc. They are also used for microphone signals, provided that they are connected to a patch panel. Using jacks and plugs with active loudspeakers is also possible.
2-pole connectors (tip & sleeve) or 3-pole connectors (tip, ring & sleeve) are available.
In the amateur Hi-Fi world, it is common to use 3-pole connectors for stereo signals (headphones) and 2-pole connectors for mono signals.
In the professional broadcast and audio industry, 2-pole connectors together with unbalanced cables are used for short or interference-insensitive transmissions (guitar cables).

For sensitive applications such as digital transmissions or for longer distances, it is common to use 3-pole connectors with balanced cables to avoid EMI interferences. However, it is still a mono signal.
