Cutting Edge Software and Hardware - The Symetrix Radius NX 12x8 Digital Signal Processor with Dante

The Radius NX 12x8 features optional factory installed 64×64 redundant Dante and identical DSP resources. Containing 12 mic/line inputs and 8 outputs, the Radius NX 12x8 supports an optional 128 (64x64) channels of redundant Dante network audio.

A Next-generation SHARC Dual-core Processor enables a Composer Super Matrix - placing the burden of large matrices in one core while freeing the second core for general purpose signal processing - making it possible to design very large and complex systems around a single Radius NX. View modes make navigating through large matrices a breeze.

A Configurable 4-port Gigabit Switch serves both Dante and control networks. It eliminates or reduces the need for external switches and prevents 100 Mbit bottlenecks. Ultra-low Noise Preamps with digitally controlled 3dB gain steps contribute to the unmatched sonic superiority Symetrix has always been known for. An optional card slot, supporting all currently available Radius and Edge Expansion Cards, adds special-purpose functionality and maximizes input or output counts to reduce total system cost. When large numbers of analog inputs and outputs are required, Radius NX connects directly to a complete lineup of software-controlled Dante-enabled Analog I/O Expanders when the optional Dante card is installed.
