    Radius NX

    Two models.  Radius NX 4×4 (4 analog inputs, 4 analog outputs) and Radius NX 12×8 (12 analog inputs, 8 analog outputs). Both feature optional factory installed 64×64 redundant Dante and identical DSP resources. The two differ only in analog I/O, logic output, and external control input capacity. The reduced cost of the 4×4 makes it extremely competitive in applications where many Dante endpoints are routed to a primary DSP and fewer analog connections are required. Models without Dante provide even more accessible DSP pricing for smaller systems.

    Optional user installed virtualized and scalable AEC coprocessor module.  For conferencing applications the dual-core coprocessor provides up to 16 channels of full bandwidth AEC with unparalleled clarity and intelligibility.

    USB audio port.  Enables soft-codec conferencing and computer-based multitrack recording or playback.

    USB host port.  Supports recording, audio media playback, and digital messaging.

    128×128 Super Matrix.  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.

    Configurable 4-port gigabit switch.  Services both Dante (when installed) and control networks, eliminating or reducing the need for external switches while avoiding 100 Mbit bottlenecks.

    Ultra-low noise preamps.  Digitally controlled 3 dB steps facilitate precise gain setting resulting in unmatched sound quality.

    Option card slot.  Accepts all user installed Radius and Edge Expansion Cards, maximizing Radius NX input/output counts or adding special purpose functionality to reduce total system cost.
