Symetrix AEC Module, AEC-2 Dual Core AEC Coprocessor, 16/12 channels (dual/independent references)
Two models. The Radius NX 4×4 (with 4 analog inputs and 4 analog outputs) and the Radius NX 12×8 (with 12 analog inputs and 8 analog outputs) both feature 64×64 redundant Dante networking and share identical DSP resources. Their primary differences lie in analog I/O, logic outputs, and external control input capacity. The more affordable 4×4 model offers a cost-effective solution for systems relying heavily on Dante endpoints and requiring fewer analog connections.
Optional 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 upcoming recording and archiving, audio media playback, digital messaging, and automatic unit backup for rapid field swaps.
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 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 Radius and Edge Expansion Cards, maximizing Radius NX input/output counts or adding special purpose functionality to reduce total system cost.
