About this User Guide
This user guide applies to the RedNet AM2 Dante headphone and line output interface. It provides
information about installing and using the unit, and how it can be connected into your system.
A RedNet System User Guide is also available from the RedNet product pages of the Focusrite
website. The guide provides a detailed explanation of the RedNet system concept, that will 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 they are fully aware of all the possibilities that RedNet and its software have to offer.
Should either user guide not provide the information you need, be sure to consult:
www.focusrite.com/rednet, which contains a comprehensive collection of common technical support
queries.

INTRODUCTION
Thank you for purchasing the Focusrite RedNet AM2.
RedNet AM2 provides two channels of premium D-A conversion in the form of a stereo monitoring
unit, combining headphone and line outputs for monitoring of signals from the Dante Audio-over-IP
network.
RedNet AM2 includes two line-output XLRs plus a stereo TRS 1/4” jack socket. It provides high-
quality digital to analogue conversion for accurate monitoring on loudspeakers or headphones and
is designed to drive high or low impedance headphones at high levels with significant audio output
power. Two large volume control knobs are provided for Headphone and Line output levels, the latter
featuring a mute button with associated LED.
The compact unit, mounted in an enclosure based around a sturdy road-worthy aluminium extrusion,
is fitted with non-slip feet and can either sit securely on a flat surface or be mounted on top of a mic
stand using the 3/8” BSW threaded bush incorporated in the base.
Dual locking etherCON connectors are included on the rear-panel to connect to the network and to
daisy-chain to additional network devices.
The unit is powered via Power over Ethernet (PoE) or via the rear-panel barrel connector and
included DC power supply. Each PSU’s status can be monitored remotely over the network and on
the top panel.
Tailored for all environments, each unit features two network ports, PoE and DC power options,
rugged construction with latching connectors and remote monitoring – RedNet AM2 is the perfect
portable break-out solution for analogue monitoring from a Dante network.

Tri-colour LED indicates the highest signal level of the network receivers:
• Green: Signal present (illuminates at -42 dBFS)
• Orange: -6 dBFS
• Red: 0 dBFS
ID Indication – When the RedNet Control or Dante Controller applications send an ID command to the RedNet
AM2 unit, the Network (4) and Signal (5) LEDs will cycle through green–orange–red states for 10 seconds.
6. Line Out Mute / Reverse ID Switch
Press to mute the line output XLRs – the LED illuminates red when mute is active.
Press-and-hold the Mute button for 3 seconds to ‘push’ Reverse ID to the RedNet Control
application.
7. Headphone Input
Standard 1/4” stereo Jack for headphones.

1. Network Port 1 / Primary Power Input*
RJ45 [etherCON] connector for the Dante network. Use standard Cat 5e or Cat 6 network
cables to connect RedNet AM2 to an Ethernet network switch.
Power over Ethernet (PoE) can be used to power the RedNet AM2. Connect an appropriately
powered Ethernet cable to network port 1.
2. Network Port 2
Second RJ45 [etherCON] network port which can be used to daisy-chain additional devices.
This port does not accept PoE input and does not pass power out.
This port cannot be used as the secondary connection on redundant networks – network ports 1 and 2 always
function as a 2-port switch.
3. Secondary Power Input*
DC input for use where Power-over-Ethernet (PoE) is not available. Can be used in conjunction
with PoE.
When both power supplies are available, PoE will be the default supply.
4. Line Out XLRs
Two balanced output channels which can, for example, be used for monitor loudspeakers.
(Passive speakers will require external amplification.)
*For health and safety reasons, do not power-up RedNet AM2 while monitoring through headphones.
Refer to the Appendix on page 12 for connector pinouts.

RedNet AM2 dimensions are illustrated in the diagram above.
RedNet AM2 weighs 0.81 kg and is equipped with rubber feet for desktop mounting. The baseplate
includes a female 3/8” BSW thread so the unit can be mounted on a microphone stand.
RedNet AM2 generates little significant heat and is cooled by natural convection.
Power Requirements
RedNet AM2 can be powered from two separate sources: Power-over-Ethernet (PoE) or DC input via
external mains supply.
Standard PoE requirements are: 37.0–57.0 V @ 1–2 A (approx.) – as supplied by many suitably equipped
switches and external PoE injectors. Note that PoE can only be accepted at Network Port 1 and that
power is not transmitted as an output on Network Port 2.
PoE injectors used should be Gigabit capable.
To use the 12 V DC input, connect the external plugtop PSU supplied to an adjacent mains outlet.
Only use the DC PSU supplied with RedNet AM2. Use of other external supplies may affect performance or
could damage the unit.
When both PoE and external DC supplies are connected, PoE becomes the default supply.
The power consumption of the RedNet AM2 is: PoE 11.0W and DC Supply 9.8W
Please note that there are no fuses in RedNet AM2, 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 15).

REDNET AM2 OPERATION
First Use and Firmware Updates
Your RedNet AM2 may require a firmware update* when it is first installed and switched on. Firmware
updates are initiated and handled automatically by the RedNet Control application.
*It is important that the rmware update procedure is not interrupted – either by switching off power to the
RedNet AM2 or the computer on which RedNet Control is running, or by disconnecting either from the network.
From time to time Focusrite will release RedNet firmware updates within new versions of RedNet
Control. We recommend keeping all RedNet units up to date with the latest firmware version supplied
with each new version of RedNet Control.
The RedNet Control application will automatically inform the user if there is a rmware update available.
Digital Clocking
Each RedNet AM2 will automatically lock to a valid Network Master via its Dante connection.
Alternatively, if a Network Master is not already present, the unit can be chosen as the Network
Master by the user.
Pull Up and Pull Down Operation
RedNet AM2 is able to operate at a specified pull up or pull down percentage as selected in the Dante
Controller application.

OTHER REDNET SYSTEM COMPONENTS
The RedNet hardware range includes various types of I/O interface and PCIe/ PCIeR digital audio
interface cards which are installed in the system’s host computer or in a chassis. 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, 19” rackmount housings, unless otherwise stated. There are also three software
items, RedNet Control (see below), Dante Controller and Dante Virtual Soundcard.
USING REDNET CONTROL
RedNet Control will reflect the status of the RedNet units present in the system, presenting an
image representing each hardware unit.
The illustration above shows a RedNet AM2 with Mute active and with signal present on the right
channel. It has both PoE and DC power supplies available, a locked network connection and is
operating as the network master.
PoE power input – Illuminates if DC power is being received via the Ethernet cable.
DC supply power input – Illuminates if power is being received from the external DC supply.
Locked – Unit is successfully locked to the network (changes to the red cross if not locked).
Network Master – Illuminated indicating that this unit is the network master.
Reverse ID
A Reverse ID request from a RedNet AM2 unit will flash the black background in the device GUI.
Signal Metering
Both audio channels have a virtual signal level meter.
