AURUS Audio System
I/O-Interfaces
The decentralized routing matrix of the AURUS mixing-console system consists of NEXUS Base Devices interconnected via fibre-optic lines. These Base Devices are placed wherever inputs and outputs are required. Thus, external audio devices can be connected to the inputs and outputs using very short cables and are then accessible anywhere within the overall system. The fibre-optic lines distribute audio and data signals plus control and sync data.
The central NEXUS STAR router with its integrated AURUS signal processing is usually the core of such a network. The NEXUS system allows for easy upward and downward scalability and therefore flexible adaptation to customer needs.
The entire NEXUS routing system is operated and configured from external PCs or from the configuration computer integrated in the AURUS console.
NEXUS Base Devices
NEXUS Base Devices are 19'' module frames (1 to15 U) accommodating NEXUS boards as required by the customer. The front panels of the modules feature standard interfaces, allowing for Base Devices to be used directly as patch panels.
Analogue Interfaces
Full integration with NEXUS makes the excellent analogue-interface components available for AURUS. Featuring Stage Tec’s patented TrueMatch technology these include:
- XMIC+ – High-end Microphone Converter - 32-bit resolution, dynamic range = 158 dB (A)
- XAD+ – A/D-Converter Board - 24-bit resolution, dynamic range = 133 dB (A)
- XDA+ – D/A-Converter Board - 24-bit resolution, dynamic range = 131 dB (A)
- HXAD A/D converters featuring 16 analogue line terminals and 112 dB(A) dynamic range
- HXDA D/A converters featuring 16 analogue line terminals and 120 dB(A) dynamic range
- various terminal options (XLR, D-Sub, RJ45)
Digital Formats
NEXUS supports a multitude of digital audio formats such as AES/EBU, AES 42 (digital microphones) and S/PDIF, Sony SDIF-2, Yamaha MEL2 (Y2), Tascam TDIF, Alesis ADAT, MADI, SD-SDI, and HD-SDI.
NEXUS – an Extension Cable
Other modules (XTI) are available for NEXUS systems that allow for transparent serial data transmission from and to external devices via the NEXUS fibre optic network. The RS232, RS422/485, DMX, Timecode (LTC), and MIDI protocols are currently supported. The XRI and XCI boards are designed for controlling external machines featuring serial interfaces, or for switching consumer loads (e.g. red-light control).
