SSL Duality Fuse Mixing Console is firmly established as the industry standard for large-scale professional audio production worldwide. Akin to previous generations of classic SSL consoles, Duality enables engineers and producers to work quickly and ergonomically, as well as delivering superior sonic results.
It's innovative hybrid approach has found many fans, by combining a traditional analogue path and signal processing along with exceptional DAW control and integration, all within a single hardware surface. The introduction of δelta-Control launched the next evolutionary step in plug-in control for Duality, and now with integrated Fusion processing, it’s simple to add an almost limitless range of tonal character, weight and space to your mix, delivering superior sonic results on any style of production.
SSL Variable Harmonic Drive (VHD)
Each channel of Duality Fuse features a SuperAnalogue™ mic preamp and an additional Variable Harmonic Drive (VHD) preamp. The VHD Pre is a patented SSL preamp design that can deliver ultra-clean SSL grade recordings but also features the VHD circuit which can be switched into the signal path. The Variable Harmonic Drive circuit uses a 100% analogue signal path to generate rich harmonic distortion. As you increase the input gain, the Variable Harmonic Drive circuit introduces either 2nd or 3rd harmonic distortion or a blend of the two to your source material. At lower gain settings it adds gentle valve-style warmth or a touch of transistor edge. As the gain is increased the more extreme the distortion becomes until at high gain settings it delivers fierce trashy transistoresque grunge. VHD pre's give the user ultimate versatility from a studio grade preamp. Whether it's ultra-clean traditional SSL, subtle warming or totally trashy transistor distortion, VHD will change your expectations of what a preamplifier should deliver.

Industry Leading DAW control
While Duality Fuse offers a powerful, comprehensively equipped large format analogue console, it also goes further than any other analogue console by integrating seamlessly into a DAW-based facility by incorporating hands-on control of important recording, routing, mixing, and editing functions in all major DAW applications including Pro Tools®, Logic Audio®, Nuendo®, Sonar® and many others.
Plug-in Control
In the console Centre Section the DAW Control Panel includes a high quality TFT to display DAW status and Plug-in parameters, plus additional console set-up information. Below this is the DAW HUI Plug-in/Process Controller - four rotary encoders auto mapped from the DAW with integral push-push switches, and four assign keys. Two additional keys are for page up/down control. The Plug-in Editor is assigned via the channel SEL switches in conjunction with the EDIT switch. Plug-ins can also be controlled via the faders by using the Mackie Control protocol.
DAW Mixer & Environment Control
Users can assign DAW channel levels, send levels and routing functions to individual channel rotary encoders with rotary LED level display. Channel and Send levels can be "flipped" on to the main channel fader. Duality features a DAW panel in the console centre section with five vertical buttons (the Window Select Keys) allow for quick access to the most commonly used DAW windows such as the edit/arrange window or the DAW mixer window. The four uppermost buttons duplicate commonly used keyboard functions on a standard computer keyboard, including ESCAPE, UNDO, SAVE and ENTER. The lower four buttons shadow the keyboard modifier keys. In combination these buttons can remove the need for a keyboard and mouse for almost all tasks. The DAW control panel includes a Master Rotary Encoder, together with six function keys and a 2-digit display.
