Introduction
Nucleus2
Welcome to Nucleus2, SSL’s integrated DAW controller and soundcard for the Dante audio-over-IP network. Nucleus2
allows you to record audio and monitor your studio software through SSL’s legendary analogue circuitry and converters,
while placing full control of your session underneath your fingertips. While the basic configurations created by SSL’s studio
engineers allow you to get working with Nucleus2 straight out of the box, the functions assigned to much of the control
surface can be adapted to suit the specifics of your working environment, as configured within the Nucleus2 Logictivity
Remote software.
DAW Control Principles
A DAW controller is part mixing console and part computer keyboard. It is a mixing console insofar as it uses channel
strips and faders etc. to mix and manipulate audio. It is a computer keyboard insofar as, rather than affecting any audio
electronics within it, it simply sends (and receives) commands to a computer program.
Of course, Nucleus2’s two analogue channels makes it more than a DAW controller.
Nucleus2 can be used to control DAW software using either HUI or MCU protocols. These are the standardised control
‘languages’ used by the majority of DAW software on the market today: HUI is used by ProTools, MCU by Logic and Nuendo.
Please refer to your DAW software’s user guide if you are unclear which protocol you use.
The Nucleus2 control surface also replicates a number of computer keyboard keys, such as modifiers (
<Shift> , ⌘or
‘command’, <Ctrl> , <Alt> ), <Enter> and <Esc> keys, and shortcuts such as ‘Save’ and ‘Undo’. Nucleus2 uses two
connections to control DAW sessions: ipMIDI (a conventional MIDI signal, sent over thernet) for HUI or MCU control, and
USB for standard keyboard commands.
Using Nucleus2’s Layer structure, different DAW programs can be connected simultaneously, although only one can be
controlled at one time.
Because each DAW is different and the precise application of HUI and MCU protocols is specific to the DAW software being
used, this manual does not provide detailed descriptions of specific DAW operations. Please refer to your DAW User Guide
for information about how to apply the control offered by Nucleus2.

Page 2 Nucleus2 User Guide
HOW TO USE THIS MANUA
After this introduction, you will find a quick overview of Nucleus2, followed by more detailed sections covering installation,
use of the Nucleus2 Logictivity Remote, and general Nucleus2 operation.
Conventions
Throughout this manual, the following conventions will be used:
• Labels found on the Nucleus2 control surface are indicated in capitals IKE THIS.
• Labels and text shown in the Nucleus2 Remote or other computer dialogues are indicated in bold ike This.
•The few instances where we refer directly to computer filenames etc. will be shown Like This .
•Where necessary, DAW computer keyboard key strokes will be shown like this whilst function keys (as opposed to
normal numbers, symbols and characters) such as the ‘Control’ key will be shown with ‘angle’ brackets such as
<Ctrl> .
• Where DAW protocol commands appear, the command or function will be shown with ‘curly’ brackets { like_this} .
Notes and additional information appear like this.
• The Nucleus2 Logictivity Remote app will in some cases be abbreviated to just ‘Remote’.
• The Nucleus2 itself may be refered to either by name, as the ‘DAW controller’ or as the ‘control surface’.
Please be aware that screenshots shown may differ slightly in appearance from their on-screen equivalents.
Glossary
The following terms are either concerned with general DAW control, or specific Nucleus2 operations:
CC ayer A Continuous Controller (‘CC’) Profile for use with MIDI devices.
Dante Digital Audio Network Through thernet. A combination of software, hardware, and network protocols that
deliver uncompressed, multi-channel, low-latency digital audio over a standard thernet network.
DAW Digital Audio Workstation. Software which emulates a recording studio, such as ProTools, Logic and Nuendo.
ipMIDI MIDI control data sent over thernet.
HUI Human User Interface. The DAW control protocol used by ProTools and others.
ayers Different DAW programmes, one of which can be controlled by Nucleus2 at a time, though all transports can
be activated simultaneously from one transport master.
MCU Mackie Control Unit. The DAW control protocol used by Logic, Nuendo and others.
SD Card An SD memory card fitted to the rear of Nucleus2 for Profile storage.
Soft Keys Many switches on Nucleus2 can be programmed through the Nucleus2 Remote to perform DAW specific
functions. These switches are grouped together as ‘soft key sets’.
USER The USER  and USER  switches located in the centre section area of Nucleus2 are used to apply soft key
sets to the switches above and below the scribble strip displays.
V-Pot In-channel rotary encoder used to control a variety of parameters. The V-Pot is located below the digital display.
V-Sel In-channel encoder switch, used to control a variety of parameters, often associated with the V-Pot. The switch
is activated by pressing the V-Pot. Note that the VSE switch is different from the channel select (SE ) switch.

2. Nucleus2 Configurations
Connection of Nucleus2 to a Dante network requires the following:
• An thernet connection between either of Nucleus2’s thernet ports and the DAW computer(s) – fo DAW cont ol, the
Nucleus2Remote and Dante Standa d Audio, if applicable
•A USB connection between Nucleus2 and the host DAW computer(s) – for DAW eyboard commands
• Audio connections – for recording sources plus monitoring
The way in which audio is sent between Nucleus2 and the host DAW computer is dependant on the connectivity options
associated with the DAW(s) being used. The rest of this section describes the installation and connections involved in
each option.
DAWs With a Dante Network Connection
For software which can send and receive audio via any soundcard connected to the computer, Nucleus2 can be connected
directly to the DAW using the thernet connection.

DAWs With Proprietary Soundcards
Some DAWs can only receive audio via their own proprietary soundcard hardware. Many of these soundcards provide
digital (S/PDIF) connections, allowing you to take full advantage of the SSL quality pre-amps and converters. The two
Nucleus2 input channels are sent using the left and right channels of the S/PDIF Out, and the S/PDIF In feeds the monitor
inputs.
If your S/PDIF connections are coaxial (usually using phono sockets), simple coaxial to optical S/PDIF converters will
be required to connect the soundcard digitally to the Nucleus2 PRE (pre-amp) outputs.

USING THE DANTE INTERFACE ON NUC EUS2WITH AN EXISTING I/O SETUP
There are several ways to integrate the Nucleus2mic pre’s & monitor section with an existing sound card setup.
On pages 6&7 there are example setups that use the Nucleus2optical SPDIF and analogue I/O for connecting an external
sound card; an alternative is to use Dante Via.
Dante Via is a soware that allows you to route audio sources on your computer to the Dante network (and therefore to
the Nucleus2Dante soundcard). The example below shows how Pro Tools I/O can be used alongside Nucleus2; outputs
1 and 2 of Pro Tools are going to Dante Via, and routed using Dante Controller to the Nucleus2monitoring section. The
Nucleus2outputs 1 and 2 (from the SuperAnalogue mic pre’s) are routed over Dante to Dante Via, which routes them to
inputs 1 & 2 of Pro Tools.
Dante Via Install and Setup
1. Go to www.audinate.com
2. Go to Products > Dante Via
3. Click on Buy Dante Via, select your OS from the dropdown menu, then click and download the installer. At this point
you can purchase a Dante Via license, or use the free trial.
4. Run the Dante Via installer and open the soware – please note that you will need to ‘stop’ Dante Virtual Soundcard, if it is
already running.
You will also need to install Dante Controller – instructions on how to do this can be found on pages 10&11.
Configuration
On the le side of the Dante Via window is a list of Audio Sources, and on the right Audio Destinations.
1. Under the Audio Sources list, click Enable Dante for the soundcard you wish to connect to the Dante network.
2. Under the Audio Destinations list, click Enable Dante for the soundcard you wish to connect to the Dante network.
The soundcard will now be available on the Dante network, and visible in Dante Controller.

4. Connection and Software Configuration
PHYSICA CONNECTIONS
The Installation Guide that came with Nucleus2 contains important safety information. Please be sure to read that
guide before attempting to connect Nucleus2.
The mains power connection for Nucleus2 is via a standard 3-pin I C320 power cable into its external power supply. The
following audio and data connections can be found on the Nucleus2 back panel:
Audio Connections
PRE  IN, PRE  IN Combi inputs for Nucleus2 pre-amps 1 and 2, XLR connections are routed via the pre-amps;
plugging in a 1/4" jack will automatically select the high input impedance on the channel strip.
SEND/RETURN  and Balanced 1/4" jack Insert Send and Return connections for pre-amps 1 and 2. (The Sends also
function as balanced Mic-pre outputs)
Inserts can also be used on the monitor circuits – see Page 42 for details.
EXTERNA and RBalanced XLR input for connecting an additional stereo signal to the Nucleus2 monitoring
MONITOR and RBalanced XLR outputs for connecting the Nucleus2 monitoring to a pair of loudspeakers
MINI and R Balanced XLR outputs for connecting Nucleus2 to an auxiliary pair of loudspeakers
HEADPHONES 1/4" stereo headphone connections. Both sockets send identical signals
TA KBACK IN Balanced XLR input for talkback; with adjustable gain
IJACK 3.5mm stereo jack input provides an additional source into the monitoring and headphone sends
SPDIF Optical S/PDIF stereo IO. The outputs of the Nucleus2 pre-amps feed the S/PDIF output (channel
1 is left, channel 2 is right) and the S/PDIF inputs feed the xternal monitor connection
Data Connections
Both Network and USB connections must be made between Nucleus2 and the DAW computer(s) – for systems using
multiple computers, see Page 16.
NETWORK Standard RJ45 thernet connector for DAW data and Dante audio. The two ports function as a
network switch so either can be used for Dante and DAW control. The unused port may be used
for additional Dante Network devices.
USB Use a standard USB A-B cable to connect Nucleus2 to a USB port on your DAW computer. This
connection is used for keyboard commands to the DAW.
Defining Keyboard Nationality (Mac)
Nucleus2 emulates a UK keyboard. When Nucleus2 is first connected to a Mac, a dialogue will be displayed which asks
you to identify the new keyboard. In order to identify the keyboard type, the Mac then requires the key to right of the left
Shift key to be pressed. Mode switch 16 on Nucleus2 (see Page 27), is assigned a ‘Keyboard ID’ command by default;
pressing this switch will send the required keystroke to the Mac to correctly identify Nucleus2 as a UK keyboard.
FOOTSWITCH Two footswitches can be connected to Nucleus2 using the single 1/4" stereo (X-Y) jack
FOOTSWITCH connector – use a mono-to-stereo splitter cable to separate the two footswitch
connections.
TERMINA The TERMINA D-connector is used for advanced system configuration and diagnostics. We
strongly suggest not using this unless you are confident with terminal procedures and have an
in-depth understanding of quantum theory.

Page 16 Nucleus2 User Guide
CONFIGURING NETWORK CONNECTIONS
Network Wiring
To ensure the fastest possible communication between your DAW computer and Nucleus2 – and to simplify the installation
wiring – Nucleus2 communicates with your workstation over thernet using the ipMIDI driver to emulate a multiport MIDI
interface. To ensure minimum latency ipMIDI uses multicast UDP rather than TCP/IP. This means that:
• The network connection should be short and direct.
Where possible all cables should be as short as possible and only routers that can support high data transfer rates
should be used. Problems have been experienced with some domestic routers, particularly when used with Pro Tools.
Typical symptoms of a slow network connection are:
- The Nucleus2 fails to synchronise all controls when first connecting with the DAW.
- Channel controls and scribble strips on channels 9-16 fail to update reliably when using the CHANNE scroller
switches.
• All computers on the network will receive ipMIDI packets.
Notes for network wizards
Because ipMIDI uses multicast UDP packets, messages between one computer and Nucleus2will be received by all
other computers on the network, potentially causing problems in installations with more than one Nucleus2. The UDP
packets can be blocked by using a firewall router and connecting the main network to the WAN connector. The firewall
can then be configured to allow all traffic apart from UDP ports 21928 through 21947 which are used by ipMIDI and
port 50081 which is used by the Nucleus2Remote application. Note that it may be necessary to use a separate Ethernet
switch in place of the integrated firewall router switch, as some of these can not support the high data transfer rate
required. The NetGear GS108 (an eight port switch) has been used successfully at SSL Begbroke.
A pre-confi ured LAN Inte ration Network Switch can be purchased from the SSL web store.
Also see setup example on page 16
To avoid the latency and communication issues illustrated above, we recommend that Nucleus2 and the DAW computers
be connected directly on a dedicated network. In practice, most systems can be configured with a direct connection.
Assigning the Nucleus2 IP Address
The Nucleus2 IP address is configured via the Network Setup tab
in the Nucleus2 Remote.
By default, Nucleus2 uses a fixed IP address of 169.254.1.2 – the
IP Address, Subnet and Gateway shown in the picture should work
for a direct connection to a single DAW computer.
We suggest you do not attempt to change these unless you are
familiar with thernet configuration as doing so may break
communication between Nucleus2and the Remote.
If Nucleus2 must be connected via a wider network – ideally, in
that case, through a network switch or router – Nucleus2 should
probably be set to use a DHCP server (check the Use DHCP option)
to automatically set an IP Address, Subnet and Gateway suitable
for your wider network. If there is any possibility that a DHCP server
is not available the Fixed option should be used.
