1. A video router comprising:
router inputs to receive router input video signals and router input audio signals;
router outputs to provide router output video signals and router output audio signals;
an audio subsystem, coupled to the router inputs and the router outputs, to receive and mix a plurality of the router input audio signals to provide mixed audio signals, and to route the mixed audio signals to the router outputs as the router output audio signals,
wherein the audio subsystem comprises:
an audio crosspoint switch to receive input audio signals comprising the router input audio signals input to the router inputs and to route the input audio signals as output audio signals comprising the router output audio signals to be output from the video router through the router outputs,
an audio mixing subsystem, coupled to the audio crosspoint switch, to receive the plurality of the router input audio signals as output audio signals from the audio crosspoint switch and to provide to the audio crosspoint switch the mixed audio signals, the input audio signals of the audio crosspoint switch further comprising the mixed audio signals.
