All audio formats - versatile connectivity
NEXUS can handle virtually any audio signal, from analogue and digital to audio-over-IP. Even more exotic formats such as Dolby E® or audio embedded in SDI/HDSDI video streams can be seamlessly integrated.
At the same time, NEXUS modular adapts perfectly to your individual requirements, as most cards are available with different connector options. This means you can choose analogue inputs and outputs with convenient XLR connectors, if you need base devices serving directly as patch panels or stage boxes. To achieve high channel counts in confined spaces, the same cards are available with D-sub or cost-effective RJ-45 interfaces.
Accurate timing and lowest latency with TDM technology
All boards within a base device are interconnected via the TDM system bus (time domain multiplexing), which provides 256 time slots for the transmission of up to 256 signals. Regardless of the number of channels actually used, the TDM concept ensures consistent timing with minimal latency.
Adaptable network topologies
You are free to configurate your NEXUS modular audio network just as desired. The individual base devices communicate via fibre optic cables, which can interact in a point-to-point connection, as a daisy chain or as a star-shaped system. Meshed networks are of course also possible. The fibre-optic interfaces are designed as SFP ports so any mix of single and multi-mode fibres is possible within the same network.
Apart from all audio signals the fibre-optic cables transmit all of the system`s control data. Furthermore, NEXUS modular allows the transparent transmission of non-system serial data, making it a reliable data highway for a wide range of applications.
Calm in itself and open to all
As a proprietary system with distributed intelligence and extensive monitoring and redundancy options, NEXUS modular is a paradigm of maximum reliability, in a way that open concepts can hardly match.
At the same time, with NEXUS modular you don't have to do without the conveniences of the modern IP world. Via Dante and AES67 interfaces, the system connects seamlessly to established audio-over-IP formats, maintaining maximum operational reliability and flawless audio integrity under all circumstances - even when components from different manufacturers interact.
Comprehensive control - anytime, anywhere
Based on the experience of countless installations the PC control application of NEXUS modular has been optimised over decades. It can be customised to meet individual requirements and combines complete control with great simplicity.
Each individual base device provides access to the control functions of the entire network. Alternatively, individual sub-areas can be viewed separately. For maximum operating convenience even in very large installations, it is possible to use several control PCs with different users at the same time.
Comprehensive metering is a fundamental requirement for any professional audio production. The NEXUS modular PC control application meets this demand in particular and provides a customizable metering tool, that can monitor every single source and destination of the system. The desired signals can be freely defined in groups and arranged on several layers. It is possible to operate multiple meter configurations simultaneously at different locations in the network. Of course, all signal levels can also be transmitted to external monitoring systems.
Powerful logic functions - individually configurable
The possibilities of NEXUS modular do not end with flexible audio distribution.
Hidden under the hood is a powerful logic system that is just as suitable for internal tasks as it is for external media control - or any possible combination of both. Furthermore, the NEXUS modular logic can implement rules for emergency scenarios which are automatically called up if certain signals or components fail.
Algorithms for a wide range of applications can be individually configured and are then burned into the flash ROMs of the base devices` XCPU boards. This ensures that once a function has been implemented, it can no longer be changed by the user. The logic is a perfect example of the core competence of STAGETEC: Solutions, that combine maximum flexibility with the reliability of a closed system.
Seamless integration of external systems
Being a true cosmopolitan, NEXUS modular is incredibly communicative with external systems. The 24 GPIOs of the XRI card enable logic interactions with installation components such as switches, signalling devices or sensors, while the universal control card XCI ensures seamless communication with DAWs or media controllers.
In addition to an Ethernet interface, the XCI offers up to four serial ports, which can be configured as RS-232, RS-422, RS-485 or MIDI. Installing the software directly in the card's flash ROM ensures maximum operational reliability. In addition, the XCI enables any parameters of the NEXUS modular universe to be monitored as part of an SNMP scenario. In the event of an incident, SNMP traps with corresponding information are sent to external monitoring systems.
The XACI card is the interface to the modern network world and offers control of the NEXUS system via OSC and Ember+. Furthermore, customer-specific solutions such as web servers, the web software of the NEXUS 4Split or the web remote control of the ON AIR flex mixing console can be installed on this card.
High-end processing on demand
Even without a mixing console, NEXUS modular can provide plenty of processing power - whenever you need it, as much as you want and wherever you want. NEXUS XDSP cards are installed in standard base devices and offer the same pristine audio quality that has made STAGETEC mixing consoles world-famous.
The algorithms available leave nothing to be desired: From delays and summing algorithms to equalizers, filters and dynamics processors, the XDSP provides all the tools needed for your daily routine. No matter if you want to create a simple crossover or a complex sound reinforcement system with delays and limiters - with comprehensive configuration options and detailed adjustability of all parameters, the XDSP is perfectly suited for any task. Even sophisticated functions such as an N-1 Matrix or an up- or downmix in ISOSTEM format are part of the portfolio.
Since multiple XDSP cards can be installed in one base device, there are virtually no limits to processing performance. To protect sensitive settings from unauthorized access, all parameters can optionally be hidden on the user interface.
