connect them to your existing studio equipment.
Software Installation This section lists all of the required software needed in order to make Sigma work with
your DAW.
Network Setup This section guides you through configuring Sigma to work on your computer network
and tablet/smartphone.
Connecting to and Using Sigma This section details how to operate Sigma and discusses control from the web
browser.
Example Setups This section provides some “real world” examples of how to configure Sigma in
various setups. This includes how to arrange your DAW session to work with Sigma.
Appendices ontains additional documentation for reference.
SIGMA OVERVIEW
What is Sigma and what was the idea behind it?
Sigma is a 2U, remote-controllable analogue mix engine. Sigma has 16 stereo/mono inputs and outputs, 2 mix buses (A
and B), mix bus insert points, comprehensive monitoring, a talkback input and customisable user buttons. The idea of
Sigma 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 an 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 plug-in emulation cannot achieve.
Sigma 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 Bus A and Mix Bus B master “fader” gains.
Many features on Sigma can be controlled using a MIDI learn. This means that you can use a generic MIDI controller to do
a number of things from controlling the monitor level, to switching Mix Insert points in/out.
How do I operate Sigma?
All of Sigma’s controls can be accessed through the web browser interface. The CHANNELS page is used to configure each
of Sigma’s 16 channels, whilst the MASTER page is used to configure the monitoring section and other features including
User buttons and MIDI Learn functionality. The SETTINGS page provides additional configuration options. The web browser
interface means you can also control Sigma from a tablet or smartphone.

How does Sigma work?
Sigma works by using faders in your DAW as analogue gain controls. Sigma communicates with your DAW in the same way
a control surface does, but instead uses the DAW’s fader positions to control the gain of 16 analogue “faders”. The
automation in your DAW session can be used to “ride” the levels of an analogue mix, bringing together the efficiency of
a DAW automation system with the sound of your favourite analogue outboard equipment.
The picture above is intended to give a graphical representation of how DAW automation controls Sigma’s analogue gains.
1. Automation data is generated in the DAW.
2. This data is sent over the ethernet cable from your computer into Sigma, via the relevant protocol (HUI/M U/MIDI).
3. Sigma takes the DAW automation and transforms it into analogue gain changes. This is done using MDA technology.
Think of MDA s as the “virtual faders” within each channel of Sigma.
Note: MDAC stands for Multiplying Digital to Analogue Converter. MDAC technology is used in the Duality and AWS
consoles.

FRONT PANEL
Sigma provides you with 16 stereo line inputs and 16 stereo line outputs on Tascam standard (AES59) 25-pin D-sub
connectors. Using the web browser interface, 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!
Headphones - stereo headphone output on 1/4” jack.
mportant - For health and safety reasons, do not reboot Sigma with while monitoring through headphones.
iJack Input - stereo external input on 1/8” jack (from iPod output or similar device).
Sigma 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 DB-25 connections. Access to the Main Speaker Outputs, Alternative
Speaker Outputs and the Mix A Output is provided on XLR male connectors.

FOOTSWITCH - The footswitch input is suitable for any 1/4” on/off footswitch. By default this turns Talkback On/Off,
although this can be changed in the web browser.
DC - Use with the provided power supply - the clip above the power inlet should be used to retain the power lead and so
prevent accidental removal or damage.
RJ45 - Use a standard Ethernet cable (as supplied) to connect Sigma to your computer network.
USB and PROG - The USB socket and PROG switch are for SSL diagnostic use and should not be connect or used.

CHIP (CHANNEL INPUTS) AND CHOP (CHANNEL DIRECT OUTPUTS)
All inputs and outputs for Sigma 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 HIPs.
The HOPs would be connected to your A/D to record back into the DAW.
A creative use for Sigma could be using it to automate 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.
MISCELLANEOUS CONNECTIONS
EXT, RTNS, TB - AES 59 ‘Tascam’ standard connections:
EXT - Provides a line-level stereo input available from an external source such as a professional D player.
RTNS (A+ B)- Provides connections for the stereo insert return signals of both Mix Bus A and Mix Bus B.
TB - Provides a line-level input from which you can connect the output from a talkback microphone
preamplifier.
MIX B, SENDS, H/P - AES 59 ‘Tascam’ standard connections.
MIX B - Stereo Mix Bus B outputs
SENDS - Provides connections for the stereo insert send signals of both Mix Bus A and MIx Bus B.
H/P - Provides a line-level stereo headphone output suitable for running a headphone feed into a cue mixer.
