AURATUS Audio System
Audio Processing
AURATUS’ signal-processing configuration is fixed. It is the same for all available AURATUS mixing systems and each can be operated in very similar ways.
Monitor speakers and external talkback pagers connect to the system via NEXUS, and the signals fed to nearfield speakers and to the console’s internal intercom system are carried via RJ 45 data lines.
Signal processing is always performed with 40-bit floating-point arithmetic. This approach not only guarantees outstanding audio fidelity of EQ, filter and dynamics but also ensures virtually clip-free audio processing inside the console.
Audio-Channel Structure
The audio-channel structure is derived from analogue systems principles. On the other hand, any impractical limitations have been eliminated and additional functions introduced to enhance the console’s flexibility.
From the user’s point of view, audio processing comprises the following stages: input routing, various input channels and bus types, optionally assignable output channels for bus signal processing, and output routing.
With the exception of channel-type-specific characteristics, input, bus and summing channels provide the same processing blocks at fixed positions in the signal path.
Several aux sends are stereo and can thus be used to feed multichannel effects processors.
Busses
The AURATUS’s bus system, which is part of its mixer board, provides its own bus system that can be used alongside the NEXUS TDM-bus system. The group, summing, aux and N–1 buses are used to combine the signals of all assigned channels. All bus signals can be output to NEXUS without further processing. If necessary, the buses can however, be assigned to separate channels — the »bus channels« — for additional signal processing and level settings.
Direct outputs and inserts are managed by non-summing NEXUS buses and therefore do not require summing buses.
Multichannel Formats
The multichannel concept allows for simultaneous output of a 5.1 multichannel and a downmixed stereo format.
