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.
It is a versatile audio-network and routing system for controlling studio or mixing-desk resources, for apparatus-area and broadcast-complex networking, for OB trucks, sound reinforcement, and for any other professional audio technology applications.

NEXUS STAR accommodates up to 16 boards each with 256 inputs and 256 outputs. This allows for routing a maximum of 4,096 inputs to 4,096 outputs, resulting in more than 16 million crosspoints.
If more I/O resources are required, multiple NEXUS STAR units can be cascaded. Any input can be freely routed to any output, 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 for a very high clock rate and thus supports the reliable implementation of an accordingly large number of time-slots, resulting in an internal throughput of more than 12 Gbps. This is the secret behind the extremely large routing capacity.

NEXUS STAR acts as a star router: Unlike the distributed structure of a traditional NEXUS network, the Base Devices connect to the core router in a star configuration. NEXUS STAR is located at the very heart of the network.
This topology offers maximum flexibility, is easy to implement and is very user-friendly thanks to  layout clarity. Another key benefit is the minimal cabling requirement and the resultant savings in cabling hardware.

NEXUS STAR currently supports two different interface boards designed for carrying signals over long cable runs: the RFOC optical interface board is used for connecting other NEXUS units and the RMF board supports the MADI multichannel standard format. This enables large digital audio systems including, for example, mixing consoles or multitrack recorders to be connected directly. Thanks to the modular structure of NEXUS STAR, an existing system can be upgraded with additional cards at any time.

One further benefit: Just like every other member 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).

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 using Stage Tec’s AURUS and CRESCENDO 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 notice scarcely any operational difference if they integrate a STAR router into the audio network since the STAR is fully integrated into the familiar user interface.

The latest NEXUS STAR generation is designed for use in extensive installations where absolute reliability and total redundancy are essential. Clients benefit from state-of-the-art systems and the maximum reliability achievable.
