Symetrix Radius NX 4x4 Dante + USB-B Programmable DSP, 4 mic/line in, 4 line out, USB audio, 1 I/O card slot, 64x64 redundant Dante, ARC
The Symetrix Radius NX 4×4 is a versatile audio processor, offering 4 analog mic/line inputs, 4 analog outputs, and up to 8×8 channels of USB audio. It features a flexible audio card slot for additional I/O expansion and provides optional Dante networked audio with up to 128 channels (64×64) for high reliability. The Radius NX 4×4 shares DSP resources with the Radius NX 12×8, with differences in analog I/O, logic outputs, and external control input capacity. An optional AEC coprocessor provides up to 16 channels of full-bandwidth acoustic echo cancellation, making it an ideal choice for installed applications requiring flexibility, processing power, and exceptional audio quality.
