Figure 32: Audio Modules: Internal Expansion Block Diagram
Internal expansion signal is a high speed multiplex of all the inputs on a card. It is not available external
to the frame and cannot be used to make routers larger than 144 discrete AES or stereo Analogue
inputs and outputs i.e. the maximum size within one 3U frame.
6.2.5 External Expansion
The Pyxis router is designed to expand a larger MADI router system. An audio module configured to
transcoder mode can act as a satellite device to a larger MADI routing system translating AES or
Analogue into MADI or MADI to AES or Analogue. Figure 33 illustrates a MADI router using 3 Pyxis
frames to translate MADI to and from AES or Analogue Audio.
