The NEXUS STAR audio-router system was designed by Stage Tec for the most extensive routing requirements typically found, in broadcast centres, large production companies, and exhibition grounds. The NEXUS STAR is a routing node serving as the core of a NEXUS installation
and interconnecting numerous NEXUS Base Devices scattered over separate studios and
apparatus areas via optical cables. NEXUS STAR accommodates up to 16 slot-in boards with 256 inputs and 256 outputs each. This allows for routing a maximum of 4,096 inputs to 4,096 outputs, resulting in more than 16 million crosspoints. And if even this routing capacity is not sufficient, multiple NEXUS STAR units can be cascaded. Inputs can be freely routed to any outputs, so point-to-point lines as well as point-to-multi-point sets can be created. When it came to technical implementation, Stage Tec broke new ground: Instead of a bus configuration as used on the NEXUS system, NEXUS STAR includes a dual matrix for routing inputs to outputs. This routing matrix allows a very high clock rate and thus supports the reliable implementation an accordingly large number of time-slots, resulting in an internal throughput of more than 12 Gbps. The secret of the extremely large routing capacity. |
| I/O boards |  NEXUS STAR currently supports two different interface boards designed for carrying signals over long cable runs: the Fibre-Optic Connection (FOC) boards interfacing to other NEXUS units, and a 4-port MADI board. This allows for direct connection of large digital audio systems including, for example, mixing consoles or multitrack recorders. Thanks to the modular structure of NEXUS STAR, an existing system can be upgraded with additional cards at any time. |
| Synchronisation | One further benefit: Just like all
the other members of the NEXUS family, the NEXUS STAR always operates in sync. The
system introduces a very low and constant latency of just 6 samples for all signals.
This figure makes NEXUS STAR entirely suitable for time-critical applications where
minimum latency is a must (e.g. live broadcasting). |
| Intuitive control | NEXUS STAR and the other NEXUS devices
are operated via a graphical user interface running on conventional desktop or laptop
computers. They can also be operated from the surface of Stage Tec’s AURUS,
CANTUS and CINETRA mixing-console systems. The graphical control software provides
intuitive access to, and control of, all system components. All settings can be stored,
and presets can be recalled easily. Existing NEXUS users will hardly notice any operational difference if they integrate a STAR router into the audio network since the STAR is fully integrated into the familiar user interface. |
| Reliability | The entire NEXUS system is designed
for reliability: Systems can be configured with a high level of redundancy, and every
Base Device has its own dedicated controller board. This concept of »distributed
intelligence« prevents total failure in case of malfunction. Defects are immediately
indicated by the graphical alert system. I/O boards can be replaced during operation without affecting other system components (hot-swap capability). A newly installed board is available on the system within a few seconds. Of course the NEXUS STAR router was designed with the same regard to reliability. For example, all components are largely independent and redundant, thus ensuring partial operation even in the case of component failure. |
