This may also be known as a fanout configuration. The Multiplexor Matrix is a 1xN matrix; a single input going to N number of outputs. The multiplexor is the simplest matrix configuration, allowing the input to be connected to any one output at a time. Before switching, for example, to Output 2 the connection to Output 1 needs to be disconnected.​ Below is an example of a 1x18 Multiplexor Matrix:
