Symetrix Radius NX 12×8 Fixed‑I/O DSP

The Symetrix Radius NX 12×8 is a powerful, highly configurable digital signal processor (DSP) that delivers pristine audio quality, advanced acoustic echo cancellation (AEC), and seamless Dante™ networking. Designed for professional AV installations—conference rooms, lecture halls, and houses of worship—the Radius NX 12×8 combines versatile analog I/O, USB connectivity, and robust control options into a 1 RU package.

Key Features & Benefits

• 12 Balanced Mic/Line Inputs

  • Ultra‑low noise preamps with +51 dB gain range, phantom power, mute, polarity invert, and –125 dB EIN.

  • Built‑in AEC coprocessor option (up to 16 full‑band channels) ensures clear, echo‑free audio conferencing.

• 8 Balanced Line Outputs

  • ±24 dB digital trim, mute, and +4 dBu nominal level deliver precise control of house and monitor feeds.

• Dante™ Audio Networking

  • Optional redundant card supports up to 128 (64×64) channels—ample headroom beyond your required 32×32 Dante routing.

  • Dual gigabit ports for automatic switchover ensure network reliability.

• USB 2.0 Audio I/O

  • Configurable as 1×1 echo‑cancelling speakerphone, 2×2 line I/O, or full 8×8 streaming channel matrix.

• Comprehensive Control Interfaces

  • RS‑232 serial port, RS‑485 (ARC), and built‑in web server for third‑party integration and intuitive system management.

  • Eight open‑collector logic outputs plus four analog control inputs for external switches/pots.

• Rock‑Solid Processing Power

  • Dual‑core SHARC DSP at 500 MHz delivers 6 GFLOPS and 2 GMACS, supporting complex processing chains with mixers, EQs, crossovers, dynamics, delays, and custom logic.

• Rack‑Ready & Reliable

  • 1 RU chassis with detachable rack‑ears, universal 100–240 VAC power supply, and Galvalume construction.

  • CE, UL 62368‑1, FCC Class A, RoHS compliance for global installations.

Technical Specifications
