Cross Point

A Cross Point is a notional intersection between an input and an output in a Matrix, which may be represented graphically by a cross-hatch of horizontal and vertical lines. Usually the horizontal lines represent the inputs and the vertical lines the outputs, and a cross overlaid at an intersection indicates a connection – a “cross point”.

Early analogue audio matrices used shorting pins pushed into sockets to make the connection; digital matrices use solid state switches controlled by computer.
