Concept

Audio Processor

The AURATUS’ XCMC board resides in the 19" housing of the NEXUS Base Device. This compact Base Device (a mere 3U high, although larger versions are available) 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 Base Device 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

Except for differences related to the two available console types, stereo and surround, the channel and bus structures are the same for all versions. 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.
