Overview

RedNet 3 interfaces your existing digital audio systems and components to the RedNet network, with up to 32 inputs and outputs and full software remote control. The unit includes support for AES/EBU, S/PDIF and ADAT (16 ADAT optical ports support 32 digital channels in and out – even at 96kHz, with S-MUX2) digital audio formats and allows the RedNet system to be synchronised to incoming signal clock or a word clock source.

RedNet 3 can be used simply as a means of converting 32 channels of audio and delivering it somewhere else on the network at near-zero latency. If you need to connect RedNet 3 to your computer there are three methods:

  • The RedNet PCIe card for Core Audio and ASIO applications such as Logic and Nuendo 
  • RedNet 5 for Pro Tools HD, Pro Tools HDX and Pro Tools HD Native via DigiLink connectors 
  • Directly to your computer’s Ethernet port using a standard Ethernet cable (and “Dante Virtual Soundcard”)

What is RedNet?

RedNet is Focusrite’s flagship range of modular Ethernet-networked audio interfaces that harnesses the power of Audinate’s tried and tested Dante digital audio networking system to bring studio quality sound to any modern audio application. Fundamentally RedNet is an extremely scalable, near zero latency audio distribution system that can be used to expand I/O channel count, interface digital components, and/or bridge between Pro Tools|HD or MADI and the Dante audio network.

Connectivity

• ADAT Optical inputs 1 – 8 via TOSLINK optical connectors: Each connector supports 8 channels at 44.1 or 48k, 4 channels at 96k (S-MUX2), and 2 channels at 192kHz (S-MUX4)*
• ADAT Optical outputs 1 – 8 via TOSLINK optical connectors: Each connector supports 8 channels at 44.1 or 48k, 4 channels at 96k (S-MUX2), and 2 channels at 192kHz (S-MUX4)*
• AES/EBU inputs and outputs 1 – 8 via DB25 connector (replaces port one of the ADAT inputs when in use)
• S/PDIF input 1 – 2 via coaxial port (replaces one AES bank when in use) 
• S/PDIF output 1 – 2 via coaxial port 
• Word Clock input via BNC port 
• Word Clock output via BNC port 
• Dante Ethernet port

* When running at 44.1 or 48kHz, ADAT input ports 5 – 8 are disabled and ADAT output ports 5-8 mirror output ports 1-4
