SGMA δELTA OVERV EW
What is Sigma δelta and what was the idea behind it?
Sigma δelta consists of three independent elements – one hardware component and two software components – which
when combined, form the central hub of a 16 channel music production studio.
The hardware is a 2U, remote-controllable analogue mix engine with 16 stereo/mono inputs and outputs, 2 mix buses (A
and ), mix bus insert points, comprehensive monitoring, a talkback input and customisable user buttons. The idea of
the Sigma δelta mix engine was to bring the sound of an SSL console together with all the workflow advantages of mixing
in a DAW. Sigma is built upon the same Superanalogue technology as our Duality and AWS consoles. Superanalogue
circuit design gives you extended frequency response, precise stereo imaging, clarity and depth. Sigma is designed for
the professional looking to add that extra 10% to their sound that even the best plugin emulation cannot achieve.
The Sigma δelta mix engine features LED metering on all 16 channel strips and an additional high resolution stereo master
meter. The blue rotary encoder is switchable (via a push function) between controlling the following levels: control room
monitor level, headphones, Mix us A and Mix us master “fader” gains.
The Sigma δelta Remote app is a cross-platform app through which all the mix engine functions can be accessed. The app
also takes care of loading and saving settings, enabling remote control options, as well as updating the Sigma firmware.
The third element is δelta Control. Originally developed to replace the iconic stand-alone mix system in large-format SSL
consoles, the δelta Single/16 fader plugins allow Sigma volume, mutes, mono stereo switching, and mix bus routing to
be seamlessly incorporated into the DAW workflow; volume rides and switching can entered directly as DAW automation
but are played out in the analogue domain after processing has been applied – as would happen in a traditional analogue
mixdown situation. The δelta Mix us and Monitoring plugins allow all mix bus levels and switching, plus all monitor levels
and sources to be controlled directly from your DAW, giving you complete control of Sigma from any MCU or EuCon based
control surface/app.
For users who wish to use the legacy A-FADA automation scheme, please see the legacy Sigma User Manual which
is located here: Sigma User Manual
How do operate Sigma δelta?
All of Sigma δelta’s controls can be accessed through the Remote app interface. The CHANNELS page is used to configure
and control each of Sigma’s 16 channels, whilst the MASTER page is used to configure the monitoring and mix bus
sections and supplementary features, including user buttons and MIDI-Learn functionality. The SETT NGS page provides
configuration options plus the loading and saving of Sigma δelta setup data. In addition to MAC and PC versions, the
iOS(iPad) and Android operating systems are supported for remote control from a tablet-based computer.
The Sigma δelta mix engine can also be controlled from any control surface which supports the MCU protocol. With a
controller, such as the SSL Nucleus, control of Channel level, Mute, Solo, Mono/Stereo, Mix us routing and Mono panning
is supported. Monitoring and Talkback functions have been mapped to MCU Function keys for additional flexibility;
channel labels are also returned to the control surface.
Sigma δelta is compatible with any MCU controller. This includes the SSL Nucleus, Matrix, AWS and Duality.

Page 6
The following four simple steps are all that is required to automate Sigma channel volume:
1.Open the Sigma Remote app
2.Instantiate a δelta-Control plugin on a DAW track
3. Select the number of the Sigma channel to be automated from the plugin drop-down menu
4. Activate the relevant automation mode on the DAW track
At this point, Sigma volume automation can be written directly from the plugin GUI fader or by using the standard DAW
edit tools. If a compatible MCU surface has been assigned to Sigma δelta, then the controller fader will automatically
activate writing automation instead of needing to use the mouse. Sigma δelta, plus a control surface – such as Nucleus,
in conjunction with the δelta-Control plugin, offers a hands-on automated mix experience formerly reserved for systems
costing many thousands of pounds more.
The Remote app must be open on your DAW PC/Mac for a control surface to communicate directly with Sigma δelta.
How does Sigma work?
Sigma works using SSL Logictivity™ proprietary control protocols over a standard TCP/IP network. Sigma is connected via
the network to the computer hosting the DAW software and the Remote app. oth the app and the plugin communicate
with Sigma using UDP messages to ensure minimum latency. ipMIDI messages between a compatible MCU controller, the
DAW software and Sigma also share the network.
Setup Concepts
Sigma communicates with your computer a little differently to what you may be used to... it is worth reading the
following – all of which is covered in detail in the User Guide – before setting up.
• Sigma δelta is an analogue summing unit which can be simultaneously controlled from a cross-platform Remote app,
a DAW via the δelta-Control plugins, and an MCU-compatible control-surface using MIDI
• The Remote app and the δelta-Control plugin use a standard Ethernet connection to communicate with Sigma
•δelta-Control, the Remote app and ipMIDI require that a network connection exists (via Ethernet) between your
computer and Sigma. This is set up in a similar way to configuring a wireless hub and requires selection of appropriate
settings in your network control panel in your computer
• To use a tablet device (iPad, etc.) to control Sigma, you will need a wireless router or wireless access point (AP), to
which your computer and Sigma are already connected (using physical Ethernet cables). You simply connect to your
tablet via WI-FI from the wireless router or access point. This allows the Remote app to control Sigma. This is necessary
as Sigma does not have a wireless connection of its own. See details of installation on Page 15; details of setup and use can be
found in the DAW Setup Guides (Section 6, Page 37)
• The network and MIDI control aspects of Sigma are entirely separate to the audio side of Sigma. All audio connections
are made between the Sigma unit and your computer audio interface/converters

FRONT PANEL
Sigma δelta provides you with 16 stereo line inputs and 16 stereo line outputs on Tascam analogue standard (AES59) 25-
pin D-sub connectors. Using the Remote app, the left input of each stereo channel can be selected as a mono source.
When an input is set to mono, the channel number on the front panel will glow green.
Please note that setting an input to mono does not give you 2 independent mono inputs!
Currently Sigma δelta supports one Sigma unit.
Headphones – stereo headphone output on 1/4” jack.
Import nt: For health and safety reasons, do not reboot Sigma with while monitoring through headphones.
iJack nput – stereo external input on 1/8” jack (from iPod output or similar device).
Sigma δelta also provides access to Mix Insert Send/Returns, a Line Level output for sending headphone feeds into a live
room, an external input and talkback input, all on standard D -25 connections. Access to the Main Speaker Outputs,
Alternative Speaker Outputs and the Mix A Output is provided on XLR male connectors.

CH P (CHANNEL NPUTS) AND CHOP (CHANNEL D RECT OUTPUTS)
All inputs and outputs for Sigma δelta are on AES 59 ‘Tascam’ standard D-sub connectors. Each D-sub carries up to four
stereo signals. The inputs and outputs are all operating at line-level. The direct channel outputs are sourced post-fader.
Typically, you would connect the outputs from your D/A converter into the CHIPs.
The CHOPs would be connected to your A/D to record back into the DAW.
A creative use for Sigma could be using it to automate 16 channels of an analogue desk. This could be achieved by
connecting the insert sends from the console into Sigma’s CH Ps and then connecting Sigma’s CHOPs into the insert
returns of the console.

3. Software nstallation and Configuration
Sigma δelta requires the following software to be installed onto your computer:
• Sigma Remote app – control of your Sigma δelta
•δ-Ctrl plugins – to automate Sigma; Single or 16 version as appropriate, δelta-Monitoring and δelta-Mix us
•ipM D software – Direct hardware control of Sigma from a compatible networked control surface using the MCU
(Mackie Control Unit) protocol – nly required if using a network-based control surface
•Nucleus Remote –nly required if using an SSL Nucleus as a remote control surface
Locate either the SSL Delt Control.dmg disk image (Macintosh) or the SSL Delt Control Setup.zip file (Windows),
included as part of the Sigma downloads – these contain the Sigma Remote and ipMIDI applications, the plugin installer,
the Nucleus Remote profile and the latest version of the installation and operating instructions.
The files can be downloaded from the Update section of SSL’s website here: Update
Please note: To access the Update section, the Sigma δelta unit must be registered to a user account.

iLok
The plugin uses the industry standard iLok copy protection scheme – users will need an iLok2 US key.
In the case of a new unit 1 licence is included as standard, additional licences are be available from the SSL web store.
Existing V1.0.3 customers will need to purchase a license from the SSL web store.

δ-Ctrl Single Plugin vs δ-Ctrl 16 Plugin
The δ-Ctrl Single plugin was derived from the Duality and AWS automation systems; an individual plugin for each channel
of the console.
The δ-Ctrl 16 plugin was designed to contain all 16 fader, pan and switch parameters for Sigma within one plugin instance.
Benefits of the Single Plugin
• The ability to enable/disable automation modes on individual channels of Sigma (when you write to one channel, the
other channel can be in read/off mode).
• Easy to switch plugin to automate AWS/Duality channels
Benefits of the δelta-16 Plugin
• Quicker to set up your session for automation
• Works within the control parameters set by Logic Pro
• Simpler workflow based around DAW automation system
nstallation
The δelta-16 plugin uses a separate installer from the ‘Single’ plugin; this can be found under the Downloads link for your
Sigma. Run the installer and follow the same procedure described for the installation of the ‘Single’ version of δelta.
We advise running only one type of delta plugin in each DAW session.
Your Sigma firmware and Remote browser will need updating to version 2.1.0 or above to work with all δelta plugins.
Both δelta-Single and δelta-16 work with the same ‘SSL Delta Plugin’ iLok license
δelta-Monitoring and δelta-Mix Bus
For automating Sigma mix bus levels, or for direct control of your monitor section via the DAW (particularly using a EuCon
surface), install the SSL δelta Control Mix us and SSL δelta Control Monitoring plugins.
The δelta-Monitoring and δelta-Mix us plugins have separate installers; both of which can be found in your SSL account
under My Products > Sigma Downloads. Run the installer of your plugin and follow the process described on page 6.
Both δelta-Monitoring and δelta-Mix Bus work with the same ‘SSL Delta Plugin’ iLok license.

oth apps are free to download.
Page 15

4. Network Setup
GENERAL
Sigma δelta communicates with its Remote app and the δelta-Control plugin over a standard TCP/IP Ethernet connection.
The ipMIDI software driver uses multicast UDP, rather than TCP/IP, to ensure minimum latency. Routers that support high
data transfer rates should be used. Some domestic routers have experienced problems, so please check your router
specification if problems occur. See following note.
Notes for Network Technici ns:
Because ipM D and δelta Control use multicast UDP packets, messages between one computer and Sigma will be
received by all other computers on the network, potentially causing problems with other ipM D devices / Sigma
units on your network. The UDP packets can be blocked by using a firewall router and connecting the main network
by the WAN connector. The firewall can then be configured to allow all traffic apart from the UDP ports required for
ipM D and δelta Control.
Firewall router settings: Block multicast addresses 255.0.0.37 and 255.0.0.38
Note that it may be necessary to use a separate Ethernet switch in place of an 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.
Sigma’s P Address
y default, Sigma uses a fixed IP address of 192.168.1.201. Alternatively, Sigma can be set to use a dynamically assigned
(DHCP) address if your installation precludes a simple direct connection. Switching between the two options is done in
Sigma’s SETT NGS page in the app.
Useful Built- n Features
Reverting from DHCP to Fixed P
If a situation arises where Sigma δelta is set to DHCP but you are unable to connect via a DHCP, take the following steps:
1. Power Sigma off
2. Set your computer network settings to be a fixed IP address
3. Power Sigma on
This will force Sigma into reverting to its fixed IP address.
How to Check the Current P Address of Sigma δelta
Once connected to Sigma, it is possible to change the fixed IP address as desired. In a situation where
you forget what the fixed IP address is set to, press and hold the first USER button on the front panel
and whilst keeping this held down, press the second USER button. Sigma will use the front panel LEDs
to readout the IP address it is set to.
Page 16

NETWORK CONNECT ON EXAMPLES
1. Fixed P – Direct Connection
This is the simplest way to setup Sigma with your computer. Sigma comes configured to use a fixed IP on first startup.
Please note that Macintosh computers with multiple Ethernet ports can only use one of those ports at any one time!
Using Mac ‘Airport’ and ipM D /δelta Control
If you are using a Macintosh computer, you should ensure that Airport is switched off. We
strongly recommend this as Airport is known to cause conflicts with ipMIDI/δelta Control data
and may stop Sigma from working. If you wish to use the internet, we suggest you configure
Sigma with a Router/Switch (see example 2).

Page 18
Network Connection Configuration – Macintosh
• On your computer go to System Preferences and click on the Network icon.
•Set Configure Pv4 to Manually then fill in the P Address and Subnet Mask boxes with the numbers shown. The IP
address should be in the 192.168.1.X range with a Subnet of 255.255.255.0.
‘X' should be a number between 3 and 254. Make sure that the ‘X’ number is not the same as Sigma’s address, or
any other device on the network.
Network Connection Configuration – Windows
• Go to Network and go into Local Area Connection Properties.
• Open up the option nternet Protocol Version 4 (TCP/ Pv4).
• Select Use the following P address and then fill in the P Address and Subnet mask boxes as shown below.

Page 19
2. Router (and Switch) Connection using DHCP – Allows Access to nternet
This connection method allows you to connect multiple devices to your network and access the internet at the same time.
The premise behind this method is that your Internet router acts as a DHCP server, dynamically assigning IP addresses
to all the devices on your network. The simplest configuration would be as follows:
If you have more devices that you need to connect on your network, adding an Ethernet switch will allow more things to
be connected.

3. Connection in a facility that has multiple SSL Consoles/Multiple ipM D devices
If you are in a studio that has multiple SSL consoles/ipMIDI devices, we recommend that you purchase one of our ‘LAN
integration network switches’ from the SSL web store. Due to the nature of UDP, if you have two SSL consoles/ipMIDI
devices on the same network with a normal router/switch setup, then you may find that an ipMIDI device in one room will
start affecting another ipMIDI devices in another room. Our managed switch blocks UDP data on two of the ports, solving
the problem and allowing uplinking in a multi-room facility. Please visit the following link for more details and a picture
