Overview of RedNet TNX

The RedNet TNX from Focusrite is a professional Thunderbolt-to-Dante audio interface designed for recording studios, broadcast facilities, post-production environments, and large-scale audio networks. It provides extremely high channel counts with very low latency over a single Thunderbolt connection.

Key Specifications

• 128 x 128 Dante channels at up to 24-bit / 192 kHz
• Optional Dante Ready™ upgrade expands capacity to 256 x 256 channels at 24-bit / 96 kHz
• 2 × Thunderbolt 3 ports
• Compatible with Windows and macOS
• Supports AES67 and SMPTE ST 2110 network-audio standards
• Dual Gigabit Ethernet (RJ-45) ports with:
  • Switched mode
  • Redundant network mode for critical applications
• Managed through RedNet Control software
• Thunderbolt ports provide up to 15W power for daisy-chained devices

Main Advantages

• Very high channel density without requiring multiple audio interfaces.
• Ultra-low latency, making it suitable for live monitoring and large recording sessions.
• Native integration into Dante networks, allowing audio routing between hundreds of devices over standard Ethernet infrastructure.
• Redundancy options increase reliability for broadcast and live production.
• Support for AES67 and SMPTE ST 2110 helps interoperability with other professional networked-audio and broadcast systems.

Typical Applications

• Large recording studios
• Broadcast production facilities
• Post-production and dubbing stages
• Live sound systems
• Audio-over-IP installations
• Multi-room recording and monitoring networks

Things to Consider

• It is not a traditional audio interface with microphone preamps or analog I/O. It serves as a bridge between a computer and a Dante network.
• To fully benefit from its capabilities, you generally need a Dante-based ecosystem that may include RedNet interfaces, stage boxes, consoles, or other Dante-enabled equipment.
• The optional 256×256-channel expansion requires a Dante Ready™ license upgrade.

Best For

Organizations that need large-scale, high-resolution audio networking and want a compact Thunderbolt interface capable of handling hundreds of Dante channels with professional-grade reliability. For small studios that only need a few microphone inputs and outputs, a conventional interface would usually be more cost-effective.
