Solid State Logic Sigma Delta

Remote Controlled Analogue Summing

Designed for the DAW user that seeks the legendary big sound of an SSL console while retaining the convenience of working in the box, Sigma δelta is a unique rack mounting SuperAnalogueTM mixer with full synchronised control via the Sigma Remote Control Application and Delta-Control DAW plug-ins.

Sigma δelta seamlessly brings the analogue joy of mixing on an SSL console into your DAW dominated workflow. Using MDAC technology unique to SSL, Sigma takes the SuperAnalogueTM mix buss from SSL’s Duality and AWS consoles and delivers it in a 2U rack design, with complete remote control of the analogue signal path, using either a hardware control surface and/or a simple Remote Control Application, and/or directly from your DAW using the innovative SSL δelta-Control (δ-Ctrl) plug-in. Now anyone who can drive a DAW can mix on an SSL.

Consistent feedback from the world’s leading producers demonstrates that analogue summing still brings a record together in a special way that no emulation plug-in can match. Sigma δelta and SSL’s no-compromise approach to designing audio circuits, delivers summing with an extended low-end frequency response, wide stereo imaging, clarity, depth and detail. When it comes to sonic tone and character many leading engineers state that a significant part of their ‘sound’ is the magic that happens when you drive the analogue mix buss of a console a little too hard…that delicate cohesive distortion only a pushed analogue mix buss brings their mixes. This is exactly the case with Sigma. It is at its best when pushed to that “sweet spot”, to the point where it yields that extra sonic dimension which has always been part of the legendary SSL sound.

Sigma δelta combines its true analogue tone and depth with complete integration into a DAW dominated workflow. In today’s commercial environment, fast turnaround of productions, with multiple mix tweaks and revisions, engineers and producers depend upon instant recall of all their settings. Sigma meets this demand. As Sigma’s levels are driven from your DAW, the mix recalls instantly upon session load. Furthermore, every setting on Sigma itself (mix buss routing, monitoring section and settings) can be saved and recalled at the click of a button.

An Artist and Studio monitoring section provides separate Monitor and Headphone circuits. The Main monitor output has Main and Alternative connections to accommodate 2 sets of monitors. A comprehensive switching matrix enables selection of monitor source and output. A large front panel level control uses a push-select mechanism to determine whether it adjusts Mix A, Mix B, Main Monitor or Headphone. There is also a Talkback input with adjustable Dim level. A handy front panel ijack input (3.5mm stereo socket) feeds into the monitoring section.

The Sigma Remote app offers full control of all Sigma functions plus store and recall of saved settings. It runs on a Mac, PC, iOS or Android tablet device and connects to your workstation via Ethernet (or wirelessly from a tablet via a wireless router). The user interface provides a series of intuitive pages that makes controlling Sigma’s powerful feature set straightforward. Three main screens provide control and setup of the Master Section, Channel Control and Global Settings parameters. Every parameter can be saved for future recall making swapping between projects simple and efficient.

Sigma δelta supports full direct remote control of the mix engine from any SSL MCU-compatible control surface. Supported channel functions are level, pan, solo, mute, mono/stereo, and mix bus routing. Channel labels as well as volume and pan data are returned to the surface for display. The Dim, Cut, Mono and Alt monitor functions, as well as Talkback, can be controlled from MCU F-Keys. MCU control is via MIDI over Ethernet and shares the same Network link as the Remote app and δelta-Control. Similar functionality is also available with Eucon enabled devices.

The Sigma rack unit houses the analogue summing engine, provides connectivity, a set of bright status and level LED’s, hardware controls, headphone socket and ijack input. A pair of user assignable dual action push/hold buttons on the front panel plus a foot-switch input can be assigned to the master section functions. The rear panel provides dedicated XLR connections for the Mix Bus A and the Main and Alt monitor outputs. The individual line inputs and direct outputs are connected via standard 25pin D-Sub. An additional pair of D-Sub connections handle Mix Bus inserts, Mix B output and line level Talkback input.
