TABLE OF CONTENTS

INTRODUCTION

Thank you for purchasing this Focusrite RedNet 1.

RedNet 1 is a multichannel, bidirectional analogue interface for use with a RedNet digital audio

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

method being used.

RedNet 1 provides eight analogue inputs and eight analogue outputs. A-D and D-A conversion is

24-bit at sample rates of up to 192 kHz, and up to 119 dB of dynamic range is achievable. JetPLL™

technology is employed to minimise conversion jitter.

The analogue inputs and outputs are electronically balanced on 25-pin Dsub connectors. The unit

can be conﬁgured with 0 dBFS equating to either +18 dBu or + 24 dBu to conform to the EBU or

SMPTE-RP155 standards respectively.

The front panel contains a set of LEDs conﬁrming network status, sample rate, reference level and

per-channel signal level.

About this User Guide

This User Guide applies only to the RedNet 1 analogue interface. It provides information about

installing a RedNet 1 and how to connect it into your studio system.

You will also ﬁnd a copy of the RedNet System User Guide included with the unit. This Guide provides

a detailed explanation of the RedNet system concept, to help you achieve a thorough understanding

of its capabilities. We recommend that all users, including those already experienced in digital audio

networking, take the time to read through the System User Guide so that you are fully aware of all

the possibilities that RedNet and its software has to offer.

If either User 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.

INSTALLATION GUIDE

Unit connections and features

RedNet 1 - Front Panel

1. AC Power switch

2. Tricolour LEDs indicating signal level at each A-D and D-A converter:

• Green – signal level above -42 dBFS

• Yellow – signal level above -6 dBFS

• Red – signal level is 0 dBFS (digital clipping)

3. NETWORK status ﬂags – two green LEDs conﬁrming network status:

• CONNECTED – illuminates when the unit is connected to an active Ethernet network

• LOCKED – illuminates when a valid sync is received via the network

4. SAMPLE RATE indication – ﬁve yellow LEDs; only one of these (44.1 kHz, 48 kHz, 88.2 kHz,

96 kHz, 192 kHz) will be lit at a time, to conﬁrm the sample rate that the system is running at.

5. LEVEL SETUP indication – two yellow LEDs; one of these will be illuminated to conﬁrm the

analogue reference level set for the unit, +24 dBu or +18 dBu. This is the analogue level which

equates to the internal maximum digital clip level of 0 dBFS.

RedNet 1 - Rear Panel

678

6. ANALOGUE INPUTS 1-8 – 25-pin female Dsub connector for connecting up to 8 analogue

sources to the RedNet system. All inputs are electronically balanced. See page 11 for

connector details.

7. ANALOGUE OUTPUTS 1-8 – 25-pin female Dsub connector with 8 analogue outputs from the

RedNet system. All outputs are electronically balanced. See page 11 for connector details.

8. ETHERNET – RJ45 network socket. Use a standard computer network cable to connect this

socket to a local Ethernet switch to connect the RedNet 1 to the RedNet network. The socket

has integral LEDs which illuminate to indicate connection to an active network port, and

network activity. See page 12 for connector details.

9. AC mains – standard IEC receptacle for connection of AC mains. RedNet 1 has a ‘Universal’

PSU, enabling it to operate from any supply voltages between 100 V and 240 V.

Physical Characteristics

RedNet 1’s dimensions are shown in the diagram below:

465.0mm / 18.30"

76.2mm / 3"

247.5mm / 9.74"

RedNet 1 requires 2U of vertical rackspace and at least 350 mm of rack depth, to allow for cables.

RedNet 1 weighs 4.12 kg and for installations in a ﬁxed environment (e.g., a studio), the front panel

mounting screws will provide adequate support. If the units are to be used in a mobile situation

(e.g., ﬂight-cased for touring, etc.), consideration should be given to using side support rails within

the rack.

RedNet 1 generates no signiﬁcant heat, and is normally cooled by natural convection, though an

internal cooling fan is ﬁtted. We recommend that the unit should not be used in locations where the

ambient temperature is greater than 30°C. However, if this is unavoidable, the fan can be turned on

and off from RedNet Control.

Ventilation is via slots in the enclosure at both sides. Do not mount RedNet 1 immediately above any

other equipment which generates signiﬁcant heat, for example, a power ampliﬁer. Also, ensure that

when mounted in a rack, the side vents are not obstructed.

Power requirements

RedNet 1 is mains-powered. It incorporates a ‘Universal’ power supply, which can operate on any AC

mains voltage from 100 V to 240 V. The AC connection is made via a standard 3-pin IEC connector on

the rear panel. A mating IEC cable is supplied with the unit, which should be terminated with a mains

plug of the correct type for your country.

The AC power consumption of the RedNet 1 is 30 VA.

Please note that there are no fuses in RedNet 1, or other user-replaceable components of

any type. Please refer all servicing issues to the Customer Support Team (see “Customer

Support and Unit Servicing” on page 14).

OTHER REDNET SYSTEM COMPONENTS

The RedNet hardware range includes various types of I/O interface and a PCIe digital audio interface

card which is installed in the system’s host computer. All the I/O units can be considered as “Break-

Out” (and/or “Break-In”) boxes to/from the network, and all are built in mains-powered, 2U 19”

rackmounting housings. There are also three software items, RedNet Control (see below), Dante

Controller and Dante Virtual Soundcard.

USING REDNET CONTROL

A virtual depiction of RedNet 1 will appear on-screen in RedNet Control when a unit is included in

the active system.

Metering: Each input and output has 3 virtual LEDs corresponding to the levels indicated by the

tricolour LEDs on the physical front panel. These illuminate at -42 dBFS, -6 dBFS and 0 dBFS

respectively.

Tools menu : four options are offered:

• Level Ref +24 dBu – sets internal analogue reference level for 0 dBFS to +24 dBu

• Level Ref +18 dBu – sets internal analogue reference level for 0 dBFS to +18 dBu

The corresponding front panel LEDs illuminate to conﬁrm the reference level.

• Preferred Master - allows the user to set the unit to be the system master clock source

• Cooling Fan – turns the cooling fan on and off.
