INTRODUCTION

Thank you for investing in the Focusrite RedNet system.

RedNet is a powerful, low latency, digital audio networking system designed specifically for music, 

recording studio and broadcast applications. It is based on Audinate’s Dante™, a well-established 

audio networking technology known for its extreme robustness. Dante - and the RedNet system - 

is capable of transporting up to 512 channels of bidirectional audio (at 48 kHz sample rate) over a 

single Ethernet link. The number of channels available in your DAW will depend on the host method 

being used.

RedNet  brings  Dante  technology  into  the  studio  as  the  basis  of  a  complete  system.  RedNet  is  a 

range  of  extremely  high  quality  analogue  and  digital  audio  interfaces  and  components  that  do  a 

great deal more than simply allow you to connect your digital studio through an Ethernet network: 

they will revolutionise the way you work in other ways too. Importantly, Dante is non-proprietary; 

this means it will work with any ASIO- or Core Audio-compliant DAW software, including Pro Tools, 

Logic, Cubase and Nuendo.

If you are a musician or an engineer currently using USB or FireWire-based interfaces, RedNet will 

give you a more reliable, powerful and professional system infrastructure. RedNet is a great solution 

in facilities where long cable runs are involved and/or there is a requirement to routinely reconfigure 

the various rooms making up a facility. It also has the advantage of only needing a standard network 

cable to interconnect all the I/O throughout the system, minimising installation time and impact on 

a building.

RedNet  allows  system  components  to  be  controlled  remotely  via  RedNet  software  on  a  host 

computer. Input and output interfaces can be placed anywhere on the network and hot-swapped: 

RedNet automatically recognises and reconfigures replacement units as soon as they appear.

ABOUT THIS USER GUIDE

A copy of this System User Guide is packed with each of the hardware interfaces in the RedNet range. 

The  Guide  provides  a  detailed  explanation  of  the  RedNet  system  to  help  you  achieve  a  thorough 

understanding of its capabilities; this includes the installation and use of the 

RedNet PCIe card

which 

will be a central component in many RedNet systems

.

 We recommend that all users, including those 

already experienced in digital audio networking, take the time to read through this Guide so that you 

are fully aware of all the possibilities that RedNet and its software has to offer. If the Guide does not 

provide the information you need, be sure to consult www.focusrite.com/rednet, which contains a 

comprehensive collection of common technical support queries.

Note that this System User Guide does not include a detailed description of the various interfaces; a 

separate User Guide specific to each interface is supplied with every unit, in addition to the System 

User Guide. Much of the installation and operation of a RedNet system revolves around setting up and 

configuring the system itself – these are factors which are common to all RedNet components. The 

examples used in this System User Guide necessarily use particular RedNet units, but you should 

not be concerned if your system does not include the same units – the principles of operation as far 

as the overall system concept is concerned is applicable to all RedNet hardware.
