These diagrams show how the various types of signal interconnections are implemented.

The PAforMusic glossary entry for balanced interconnections provides further information − you can find it here. Or you might like to go to the PAforMusic home page.

Here are links to definitions of the terms used in the above diagrams: Unbalanced, Balanced, Semi-balanced, Quasi-floating, Ground-compensated, Pseudo-balanced, Signal earth, Chassis, Cable, Hot, Cold, Screen, Sense, Conductor, Pole, Connector, XLR, TRS, Dynamic mic, Floating, Transformer balanced, Output impedance and Leg.

Note: The diagrams make no distinction between connections to the internal signal earth of equipment and to the equipment's metallic chassis − see Pin 1 problem.
