NEXUS SYSTEM Overview
NEXUS – Audio Infrastructure and Networked Control
The NEXUS components from Stage Tec are a family of plug-in cards with which almost all requirements for audio transmission and conversion as well as extremely complex control tasks can be flexibly implemented. Each system can be tailored exactly to the individual requirements of your installation. With NEXUS, Stage Tec uses the industrial standard of 19" subracks, which not only allows you to configure the system in a highly adaptable way, but also guarantees future expandability.
How does a Nexus System Work?
Flexible Configuration in Industry Standard
Two power supplies can be used at each level. These can be connected to one or two phases on the connection side to provide redundancy and maintain function even if one phase of the power supply fails.
Guaranteed Timing and Lowest Latency thanks to TDM Bus
Maximum Operational Reliability through Distributed Intelligence
Ethernet and USB ports are available for connecting control PCs. If individual components fail, the function of the rest of the network is completely retained. This makes it possible, for example, to use individual Base Devices on a mobile basis or only when required. Due to the burned configuration, the boot process is very fast.
Even more Network Security - Redundancy and Flexible Topologies
It is possible to make the fiber optic connections redundant in order to achieve even greater security. Not only can the fibers be plugged redundantly, but it is also possible to use several XFOC cards redundantly. This makes it possible to change the cards during operation or to patch fiber optic cables without audio failures.
Hot-Plug, Auto-Discover and Growing Matrix
Small Distances, Large Distances
All Audio Formats - Many Connector Types
Each card type provides you with certain audio formats. Nearly all formats available on the market are supported by NEXUS: from analog to digital to audio-over-IP. Even "specialties" such as Dolby E® or embedded audio in SDI/HDSDI video data streams are supported by NEXUS. Cards are often available with a smaller or larger number of channels and with different connector types. For example, the NEXUS can be designed as a patch panel at the same time, which saves a lot of installation effort. Alternatively, there are cards that can be used in control rooms with inexpensive RJ45 connectors to save space and costs.
The Advantages of a Proprietary System and yet open to Everything
NEXUS uses a proprietary protocol to transfer audio and control data. This guarantees lowest latencies and highest reliability of the system. The latency between digital input and output of two adjacent Base Devices is fixed at only 6 samples.
You don't have to do without anything, because NEXUS offers interfaces with which you can bring almost all common audio formats into the system. This also includes MADI, Dante and AES 67, so you can maintain the security and reliability of NEXUS in your central networks and maintain flexibility in connection to open standards such as IP where you need it..
Powerful Logic and Media Control
Integration of External Systems
Permanent Self-Monitoring and Emergency Solutions
When using NEXUS boards with GPIOs or serial interfaces, monitoring and control can be connected to external components and systems in a variety of ways. The universal XCI control board also makes it possible to integrate NEXUS into an SNMP scenario and monitor any parameter of the entire system. For this purpose, the XCI sends SNMP traps with corresponding information to external monitoring systems in case of an event.
Internal DSP's - High-End Signal Processing on Demand
The algorithms available on the XDSP card should leave nothing to be desired: Starting with simple delays or summers / mixers via equalizers and crossovers as well as extensive dynamic processing up to complex functions such as an N-1 matrix or upmix/downmix even in ISOSTEM format (license required), everything is possible.
All functions have in common that, as typical for Stage Tec, they are very granularly adjustable. Even the finest tuning of complex sound systems is no problem. All elements can be made accessible to the user or hidden from his access.
Extensive Sync Options and Omni-Present Sample Rate Conversion
For additional requirements, you can use one or more XSYNC cards. In addition to word clock, these cards also have a connection for video sync, which automatically recognizes the video format and the clock. All formats up to HD with bi- or tri-level sync are supported. Optionally, the connection can also be configured as a master. Since Nexus works very stable with one clock throughout the system, it is possible to distribute an internal or external sync over long distances and to many connected systems.
Unlimited Metering and Monitoring
The PC software that comes with every NEXUS system contains a stand-alone tool for displaying any signal level of the entire network. Desired signals can be freely defined in groups and stored on multiple layers. The software can be operated at different locations, each with its own configuration. At the same time, NEXUS is able to make all signal levels available to external systems for monitoring. In addition to the NEXUS proprietary protocol, which can handle a large number of media control systems from well-known manufacturers, NEXUS also supports the EmBER+ protocol when using an XACI board.
For monitoring applications that require the convenience of a configurable hardware interface, Stage Tec offers the NEXUS Monitor Control, a slim, small touch console optimized to make complex monitoring tasks along with control functions manageable. Of course, a NEXUS system also plays together with any goniometer from other manufacturers.
Mixing Consoles from 4 - 96 Faders and up to 800 Audio Channels
Nexus Star Router - Dedicated 4,096 x 4,096 Matrix and Star Point
Stage Tec also offers MADI cards for the Star Router for connecting external, high channel systems directly to the matrix. These RMF cards each have 4 MADI ports.
In addition to the pure router functionality, a Star Router can also accommodate the control and processing cards of the larger mixing consoles. Up to two consoles with up to seven RMDQ processing cards each can be accommodated.
Mega Matrix for Special Applications - 8,448 x 8,448 Inputs and Outputs
NEXUS is an extremely flexible system with an enormous number of possible uses. Starting with individual Basic Devices, which can be used purely for format conversion and/or synchronization, to smaller systems, which can be used in schools, hospitals, sports facilities, shopping malls, etc. with maximum operational reliability and longevity. From the most complex systems for broadcasters or large airports, everything is possible. Please do not hesitate to contact us!
