Experience classic SSL analogue processing for the API 500 rack. Discover why this system enjoys such a large and enthusiastic customer base.
Duality 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.
Comprehensive DAW Workstation Control
Hardware control over two DAWs simultaneously with high speed Ethernet connectivity.
Fader Control From The Sweet Spot
8 group faders and master fader focus, enable you make level adjustments and solos from the centre of the console.
Constant Visual Feedback
New look Channel TFT screens deliver complete optical feedback of channels status, processing, routing etc, and the innovative Eyeconix icons.
Multi Operator Total Recall
With channel Autoscan, utilising the welcome real estate of the TFT screens, allowing more than one operator to recall the console.
Beautiful, precise SSL SuperAnalogue™ mix buss

Integrated Fusion processor - Limitless sonic flavors for any production style
Dual Mic Pre’s - SuperAnalogueTM & VHD
From the purity of your microphone through to creative distortion and all the stops in between through the versatile Variable Harmonic Drive (VHD) circuit.
SSL Bus Compressor
The classic SSL master bus compressor can work in Stereo or 5.1 mode, with useful side-chain functions for complete control.
Classic SSL Processing on every channel
Each channel strip features a compressor/gate, high and low pass filters and EQ (switchable between E/G series curves).
NEW! δelta-Control Automation
Seamless integration with all the benefits of classic SSL analogue console automation and DAW based workflow.
On Board SSL Automation
The traditional SSL automation system with all of the much loved SSL modes.
Classic SSL console benefits without the overheads of a vintage console
Reduced overall power consumption demands, minimised requirement for air conditioning and controlled maintenance costs (via standard warranties and available service contracts) all contribute to reduced overall running costs.
Split Signal Flow Channel Architecture
Unique dual path channel architecture provides unrivalled flexibility for placing processing in the record/monitor paths.
3 stereo mix busses and 24 track busses for flexible routing. Internal busing feature allows patch-free sub groups by allowing channels inputs to be sourced from track bus outputs.
Complete 5.1 Surround Support
Full range of monitor calibration and setup options for today’s surround productions.
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.
δ-Ctrl is a native AAX/AU/RTAS/VST/VST3 plug-in that allows automation of Duality Fuse as if it were a DAW Plug-in. The automation system in the DAW is used to record and playback control data from the faders and switches on the console as an alternative to using the SSL legacy automation system in Duality Fuse. The δ-Ctrl plug-in is inserted into a DAW mixer audio channel. The plug-in then receives and sends control data from an assigned Duality Fuse channel, VCA or Master fader via a high speed Ethernet Network connection. Audio on the DAW track passes through the plug-in slot unprocessed so the plug-in can be combined with other DAW plug-ins. The console Fader, mutes and relevant switches are represented as plug-in parameters in a δ-Ctrl plug-in GUI and their automation data is recorded to the automation lane of the selected DAW channel. In playback the plug-in converts the stored automation data from the DAW into δ-Ctrl messages and routes these back to the console via the SSL Logictivity Network connection.
Duality Fuse combines the analogue colouration tools of Fusion with our industry-standard large-format Duality SuperAnalogue™ console, adding the detail, warmth and finesse that only real analogue circuits can provide.
The addition of Fusion to the centre section brings even more flexibility to this industry-leading console and only adds 90mm/3.5-inches to the width. There’s flexible, patch-free press-button routing with Mix Bus A and Stereo Submix inserts, plus an independent Fusion Insert on patch. The simple vertical layout of the panel is intuitive, with high-quality rotary controllers for Vintage Drive, EQ, compression and precision stereo image control, plus four user buttons with indicators.
The new Duality Fuse console contains many workflow enhancing features thanks to the integrated Fusion panel in the central section. These include:
Press button routing
– Mix Bus A Insert
– Stereo Submix Insert
– Independent patch routing
Precision image adjust
– 31-step control, with ±1dB image shift
– Rebalance processing image changes
Four user keys
– Opto-isolated indicators / tallies
– Relay closure outputs
– Programmable latching/momentary action
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.
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.
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.
Duality Fuse Pro-Station is a version of Duality Fuse that offers an alternative centre section layout. Functionally Pro-Station offers all of the same features and benefits as a standard Duality Fuse. The winged layout of the Pro-Station is designed to serve producers and engineers who wish to conduct their DAW session editing/arrangement and audio mixing from a single central position. In many studios a separate dedicated DAW station is located adjacent to the console and the task of operating the DAW for editing and arrangement is separated from the audio mixing process. Duality Fuse Pro-station will appeal to producers and engineers who like hands-on DAW operation that combines the recording, editing, arrangement and mixing processes.
