An audio router is a device that transports
audio signals from inputs to outputs.
Inputs and Outputs
The number of inputs and outputs varies dramatically. The way routers are described is normally ''number of inputs by number of outputs'' e.g. 2x1, 256x256.
Signals
The type of signals transported - switched can be
analogue - Analog - audio signals or
Digital
Digital usually refers to something using discrete digits, often binary digits.

usually is in the
AES/EBU standard for broadcast use. Broadband routers can route more than one signal type e.g. analogue or more than one type of digital.
Crosspoints
Because any of the inputs can be routed to any output, the internal arrangement of the router is arranged as a number of crosspoints which can be activated to pass the corresponding signal to the desired output.
