AURATUS Concept
Audio Processor
The AURATUS’ XCMC board resides in the 19" housing of the NEXUS Base Device. This compact Base Device (a mere 3 U high) takes care of all audio processing routines for the AURATUS mixing system and all the input/output routing. In addition, it contains audio interfaces, to which external gear can be connected. A typical AURATUS/NEXUS system usually contains the following boards:
- An XCMC board handling all audio processing and console operation
- An XCPU Base-Device controller board for routing functions, etc.
- Audio-interfaces boards (depending on the requested audio formats)
- XFOC interface boards to connect additional Base Devices as required
- XPSU power supplies (redundant versions are possible)
Channels and Busses
Channel and bus structures are permanent. This approach enables the use of just a single high-performance, yet compact and low-power board for all signal processing and console control tasks.
With a view to saving processing power where it isn’t usually needed, AURATUS contains several channel types with different controls and functions: input channels, summing, group, auxiliary, and N–1 bus channels. There are also a monitor channel, a talk channel, a PFL channel, and a downmix matrix.
