NEXUS On Air Integration

nexus-05-2011-6heNEXUS is a distributed audio network. Networking several NEXUS Base Devices with the help of fiber-optic connections or introducing the NEXUS STAR allows routing of up to 4096x4096 signals.

Cascading multiple STAR’s results in an almost unlimited highly efficient routing capacity with minimal wiring and maximum redundancy. Full system start up and reboot after power failure within a few seconds = audio in network.

In addition to audio, the system distributes and generates various serial formats such as RS232, RS422, RS485, MIDI, DMX, LTC and machine control. This capability is especially valuable for simplifying installations and giving control connections same the protection of NEXUS resilience and redundancy as the audio.

NEXUS Concept

Fiber-optic connections and power supplies are redundant. All module boards can be hot swapped.

Multiple control PC’s can be connected to the NEXUS router and if needed, set up as an Admin/Users network with user rights. PC’s only needed for configuration, no audio processing.

The system performs the required format conversion »on the fly«.

The On Air 24 has a 19''/1U interface core that connects directly to the Nexus XCMC, a combined DSP and control card. Nexus provides the TDM routing and all the I/O in a single or fiber networked racks.

The interface core provides I/O at the desk position for head­phones, nearfield speakers and metering. It also provides the interfacing hardware for the direct connection of a touchscreen interface.

NEXUS Base Devices

1-heNEXUS Base Devices are 19'' frames and range  from 1 to 15 units in height. Each 3U row is equipped with an active NEXUS backplane and accommodates up to 20 plug-in boards while a 9U  has a capacity of 60 boards.

Each Base Device is equipped with an XCPU controller board for complete autonomy. Thus, the availability of basic functionality is assured regardless of the presence or absence of optical lines and control computers.

nexus_star_1_14The NEXUS can also be used as an I/O router for STAGETEC mixing-console systems. Multiple console systems can coexist on a single NEXUS network.

All NEXUS inputs, outputs, and processing channels can be accessed and operated from anywhere on the routing system. In the control program, a single crosspoint simply connects an input to an output — it is up to the system to establish the most effective connection on the Base Device network.

Adding the NEXUS STAR provides a routing capacity of 4096 x 4096. Also multiple STAR’s are possible in one network.

NEXUS Interfaces
