INTRODUCTION
Thank you for purchasing the Focusrite RedNet D16/D16R.
RedNet D16/D16R is a 1U 19in rack-mount interface featuring 16 channels of AES/EBU connectivity
to and from a Dante audio network – perfect for bridging between digital consoles, power amplifiers
or any other AES3 equipped audio equipment and a Dante network.
Dual Ethernet connectors (primary and secondary) on the rear-panel allow maximum network
reliability with seamless switchover to a standby network in the unlikely event of a network failure.
These ports may also be used to daisy-chain additional units when operating in Switched mode.
RedNet D16/D16R has a Sample Rate Converter (SRC) on each input pair allowing instant operation
with any AES3 source irrespective of the sample rate or clocking of the Dante audio network.
Audio interface is provided by two standard 8-channel (AES59) Combined Digital I/O DB25 connections.
In addition, a duplicate of channels 1 & 2 is available on a pair of XLR3 connectors.
S/PDIF input and outputs are provided on RCA connectors; ideal for connecting CD players or solid-
state recorders. The input replaces channels 3 & 4 in the DB25 connector while the output can be
assigned to replicate any adjacent odd/even pair.
Word Clock I/O on BNC connectors allows synchronisation of the Dante network to house clock, or
syncing external equipment to the Dante network. DARS reference can also be accepted via the XLR
input connector.
The RedNet D16/D16R front panel contains a set of LEDs to confirm network status, sample rate,
clock sources and signal presence on both input and output.
RedNet D16
RedNet D16R
D16R
Redundant power supplies (PSU A and B) with separate input sockets on the rear panel allow one
supply to be connected to an uninterruptable source. Each PSU’s status can be monitored remotely
over the network or from the front panel.

• PSU B – Illuminates when an AC input is applied and all DC outputs are present.
When both supplies are functioning and have AC inputs PSU A will be the default supply.
3. RedNet Network Status Indicators:
• PRIMARY – Illuminates when the device is connected to an active Ethernet network. Also
illuminates to indicate network activity when operating in switched mode.
• SECONDARY – Illuminates when the device is connected to an active Ethernet network.
Not used when operating in Switched mode.
• LOCKED – Illuminates when a valid sync signal is received from the network, or when the
RedNet D16/D16R unit is Network Master. Flashes if external clock is selected but not
connected.
4. RedNet Sample Rate Indicators
Five orange indicators: 44.1 kHz, 48 kHz, x2 (multiple of 44.1 or 48), x4 (multiple of 44.1 or 48)
and sample rate PULL UP/DOWN. These Indicators illuminate individually or in combination
to indicate the sample rate being used. For example, for a 96kHz Pull Up/Down setting, the
48kHz, x2 and Pull Up/Down indicators will illuminate.
5. Signal Presence LEDs
LEDs Indicate whether an input or an output signal is present for each odd/even channel pair.
Illuminate at -126dBFS.
6. Clock source
Five orange indicators: Word Clock, DARS, Input 1-2, Input 9-10 and Internal. Whichever is
lit identifies the clock reference being used. When an incoming clock source is invalid, the
‘Locked’ indicator will flash to indicate that the unit has reverted to using its internal clock.

Power Connection
IEC Power Cord Retaining Clip
RedNet D16/D16R is supplied with IEC power cord retaining clips. These prevents accidental
disconnection of a power cord during use. When the unit is first installed, the retaining clips will
need to be attached to power input socket[s] on the rear panel.
Insert each clip by squeezing together the legs as shown in the first image below, aligning the pins
with the through-holes on the IEC fixing posts one at a time, and then releasing.
Ensure that the orientation of each clip is as shown in the other images below or the effectiveness
will be compromised.

11
Physical Characteristics
RedNet D16/D16R dimensions are illustrated in the diagram above.
RedNet D16/D16R requires 1U of vertical rack space and at least 350 mm of rack depth, to allow for
cables. RedNet D16/D16R weighs 3.74 [3.84] kg and for installations in a fixed environment (eg., a
studio), the front-panel mounting screws will provide adequate support. If the units are to be used
in a mobile situation (eg., flight-cased for touring, etc.), consideration should be given to using side
support rails within the rack.
RedNet D16/D16R generates little significant heat and is cooled by natural convection.
Ventilation is via slots in the enclosure at both sides. Do not mount RedNet D16/D16R 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 D16/D16R 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[s] on the rear panel.
One or two mating IEC cables are supplied with the unit – these should be terminated with mains
plugs of the correct type for your country.
The AC power consumption of the RedNet D16/D16R is 30VA.
Please note that there are no fuses in RedNet D16/D16R, 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 18).
465.0mm / 18.3”
31.8mm / 1.25”
263mm / 10.35”
D16R
When PSU A & PSU B are both connected, PSU A becomes the default supply and therefore draws
more current than B. If a backup mains supply is provided from an uninterruptable source, it is
recommended that this is connected to input B.

12
REDNET D16/D16R OPERATION
First Use and Firmware Updates
Your RedNet D16/D16R 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 D16/D16R unit 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.
Digital Clocking
Each RedNet D16/D16R will automatically lock to a valid Network Master via its Dante connection.
Alternatively, If a Network Master is not present, then the unit can be chosen as the Network Master
by the user.
Pull Up and Pull Down Operation
RedNet D16/D16R is able to operate at a specified pull up or pull down percentage as selected in the
Dante Controller application.
Sample Rate Converters
SRC will need to be switched in for any sources that are not using the current system clock as a
reference signal.
SRC can be switched in or out separately for each input channel pair.
Note that engaging the sample rate converters will increase the overall latency of the device.

13
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,
19” rackmount housings. 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 D16R with 16 input signals (SRC switched in for channels 1–2
and channels 13–14) and signal present on five outputs.
PSUs A & B – Each illuminates if PSU has power input and all DC outputs are present
Networks – Each illuminates if a valid connection is present.
Locked – Unit is successfully locked to the network (changes to the red cross if not locked).
Network Master – Illuminated, indicating that unit is network master.
External Clock – Green: Illuminates when external clock is selected and locked.
Amber: Illuminates when external clock is selected but not locked.
Red: Illuminates when external clock is selected but not connected.
Signal Metering
Each input and output channel has a virtual signal indicator. Five different states are represented:
Black: No signal present
Dim green: > –126 dBFS
Green: –42 dBFS
Amber: –6 dBFS
Red: 0 dBFS
–SRC– : Indicates sample rate converters are switched in for an input channel pair.

Focusrite RedNet Warranty and Service
All Focusrite products are built to the highest standards and should provide reliable performance
for many years, subject to reasonable care, use, transportation and storage.
Very many of the products returned under warranty are found not to exhibit any fault at all. To
avoid unnecessary inconvenience to you in terms of returning the product please contact Focusrite
support.
In the event of a Manufacturing Defect becoming evident in a product within 12 months from the date
of the original purchase Focusrite will ensure that the product is repaired or replaced free of charge.
A Manufacturing Defect is defined as a defect in the performance of the product as described and
published by Focusrite. A Manufacturing Defect does not include damage caused by post-purchase
transportation, storage or careless handling, nor damage caused by misuse.
Whilst this warranty is provided by Focusrite the warranty obligations are fulfilled by the distributor
responsible for the country in which you purchased the product.
In the event that you need to contact the distributor regarding a warranty issue, or an out-of-warranty
chargeable repair, please visit: www.focusrite.com/distributors
The distributor will then advise you of the appropriate procedure for resolving the warranty issue.
In every case it will be necessary to provide a copy of the original invoice or store receipt to the
distributor. In the event that you are unable to provide proof of purchase directly then you should
contact the reseller from whom you purchased the product and attempt to obtain proof of purchase
from them.
Please do note that if you purchase a Focusrite product outside your country of residence or business
you will not be entitled to ask your local Focusrite distributor to honour this limited warranty,
although you may request an out-of-warranty chargeable repair.
This limited warranty is offered solely to products purchased from an Authorised Focusrite Reseller
(defined as a reseller which has purchased the product directly from Focusrite Audio Engineering
Limited in the UK, or one of its Authorised Distributors outside the UK). This Warranty is in addition
to your statutory rights in the country of purchase.
