Symetrix 80-0134 Radius NX 12x8 Dante + USB-B

Product Overview

The Symetrix Radius NX 12x8 Dante + USB-B (SKU: 80-0134) is a 1U rack-mount open-architecture DSP processor engineered for demanding conferencing and commercial AV installations. Providing 12 balanced analog inputs, 8 balanced analog outputs, onboard 64x64 Dante networking, and a built-in USB-B port for direct BYOD soft-codec audio, the Radius NX 12x8 is a purpose-built conferencing DSP that eliminates the need for a separate USB audio interface in Teams, Zoom, and Cisco WebEx rooms. An optional AEC coprocessor module adds up to 16 channels of hardware acoustic echo cancellation, making it suitable for board rooms, training rooms, and large conference rooms requiring high-quality far-end audio.

Product Description

The Radius NX 12x8 delivers next-generation SHARC dual-core processing with ultra-low-noise preamps and digitally controlled gain steps across its 12 mic/line inputs, providing the headroom needed for multi-microphone conference room installations with ceiling array or boundary mic configurations. The high-retention USB-B connector provides a reliable, direct connection between the DSP and a room PC for BYOD conferencing — no USB hub or external interface required. The 64x64 Dante network audio interface (AES67 compatible) connects the Radius NX 12x8 to distributed Symetrix xIO endpoints, ceiling speaker feeds, amplifiers, and other Dante-enabled devices on the same network. The onboard 4-port gigabit switch serves both the Dante audio network and the control network, simplifying rack wiring. An optional AEC coprocessor module installs internally and adds up to 16 AEC channels for acoustic echo cancellation without occupying expansion card slots. The Radius NX 12x8 is programmed in Symetrix Composer, the same free open-architecture software used across the entire Symetrix platform. It can share a single Composer site file with Prism, EDGE, Server D100, and xIO endpoints.

Key Features

• 12 Balanced Analog Inputs — Ultra-low-noise mic/line preamps with digitally controlled gain steps; phantom power on mic inputs.
• 8 Balanced Analog Outputs — Balanced line-level outputs for speaker feeds, amplifiers, and signal distribution.
• 64x64 Dante (Onboard) + AES67 — Full 64-channel bidirectional Dante networking for AVoIP integration with third-party Dante devices.
• Built-In USB-B for BYOD Audio — High-retention USB-B connector provides direct soft-codec audio integration without a separate USB interface; compatible with Windows and macOS.
• Optional AEC Coprocessor (Up to 16 Channels) — Internal AEC module adds hardware echo cancellation; does not consume expansion card slots.
• 4-Port Gigabit Switch — Onboard switch consolidates Dante audio and control networking, reducing rack wiring complexity.
• Open-Architecture Composer Programming — Free software, no per-seat license; full graphical DSP design identical across all Symetrix platforms.
• 1U Rack-Mount — Compact form factor for AV equipment rack installation in conference rooms and AV closets.

Typical Applications

• Boardrooms and Conference Rooms — Full conferencing DSP with mic processing, AEC, and USB-B BYOD for Teams, Zoom, and WebEx.
• Microsoft Teams Rooms and Zoom Rooms — Native USB-B audio interface eliminates the need for a separate USB audio adapter.
• Training Rooms — Multi-mic input capacity with AEC supports ceiling array and podium mic configurations.
• Government and Corporate Meeting Spaces — TAA-eligible Symetrix hardware with open-architecture programming for classified and secure environments.
• Houses of Worship with Broadcast — 12 analog inputs accommodate FOH and broadcast mix feeds with Dante distribution to recording systems.
• Multi-Purpose Rooms — Flexible I/O and open programming handle changing room configurations and presentation scenarios.

Frequently Asked Questions

Does the Radius NX 12x8 include AEC by default?

No. AEC is optional via an internal AEC coprocessor module (ordered separately). The module adds up to 16 AEC channels and installs inside the chassis without occupying external expansion slots.

What is the USB-B port used for?

The high-retention USB-B port connects the Radius NX 12x8 directly to a room PC and presents as a USB audio device (speakers and microphone). This allows Teams, Zoom, WebEx, or any soft-codec to use the DSP’s processed mic and speaker channels without a separate USB audio interface.

What is the difference between the Radius NX 12x8 Dante (80-0134) and the non-Dante version (80-0206)?

The 80-0134 includes 64x64 onboard Dante networking. The 80-0206 provides the same analog I/O and USB-B but without Dante; audio is distributed over analog wiring only.

Can the Radius NX 12x8 be programmed in the same Composer file as a Server D100?

Yes. All Symetrix DSP platforms — Prism, EDGE, Radius NX, and Server D100 — are compatible within a single Symetrix Composer site file.
