An audio switch for audio signal switching includes input ports for obtaining digitized audio input signals, output ports for outputting a number of analog audio output signals, and a digital matrix first stage for switching a digitized audio input signal derived from one or more of the input ports, to any one of a plurality of digital stage output ports according to a specified configuration, so as to give a number of digital stage output signals. The audio switch further includes digital-to-analog converters connected to the digital stage output ports for performing digital-to-analog conversion on a number of the digital stage output signals to obtain a number of analog audio signals and to an analog second stage for switching a number of the analog audio signals to one or more of the analog audio output ports according to a specified configuration. |
