Product Overview
The Radius NX series offers two models: Radius NX 4x4 (4 analog inputs, 4 analog outputs) and Radius NX 12x8 (12 analog inputs, 8 analog outputs). Both feature optional redundant Dante, identical DSP resources, and differ only in analog I/O, logic output, and external control input capacity. The Radius NX 4x4 is cost-effective for applications with many Dante endpoints and fewer analog connections. Models without Dante offer more accessible DSP pricing for smaller systems. Additional features include a user-installed AEC coprocessor module, USB audio and host ports, a 128x128 Super Matrix with a dual-core processor, a configurable 4-port gigabit switch, ultra-low noise preamps, and an option card slot for expansion.
