The Most Powerful Axe-Fx Ever

Unprecedented Power

The original Axe-Fx upended the industry by being the first device for musicians to put a military/industrial-grade DSP into a consumer product. Leveraging the power of this DSP allowed detail and realism that no other product had previously achieved. The Axe-Fx II expanded on this concept by putting two of those same DSPs to work. Continuing the legacy of this philosophy the Axe-Fx III harnesses the power of no fewer than four separate processors.

Two 1.25 GHz, floating-point “Keystone” Digital Signal Processors (DSPs) comprise the main audio engine*. These processors are the most powerful DSPs available delivering over twice the performance of the DSPs used in our previous generation products. To feed these advanced processors we coupled 4Gb of blazing fast PC1600 DDR3 memory, hundreds of Mb of FLASH memory, a proprietary FPGA and a rich set of peripherals.

The stunning color display is controlled by a dedicated graphics processor while USB traffic and user interface tasks are handled by a 500 MHz, 16-core microcontroller providing smooth operation and robust USB performance.

*2×1.25 GHz is the speed of the optional Turbo DSP module. The standard DSP module runs at 2×1.0 GHz.

A Powerful Interface Makes the Axe-Fx III the Most Intuitive Product Fractal Audio has Ever Created

Dynamic Color Display

Controlling all this power requires an interface to match. A large 800×480 color display features 30 times the resolution of our previous model. Custom designed to provide more brightness and contrast than “off-the-shelf” displays, this new display is optimized for readability in the most difficult conditions.

Driving the display is a dedicated graphics accelerator delivering dynamic, animated displays. Unlike the mostly static displays in other products, the displays in the Axe-Fx III feature moving knobs, meters, graphs and other dynamic content giving the user valuable visual feedback at a glance.

Sleek Front Panel

Five push-encoders plus a main encoder allow rapid data entry and parameter control. Editing is fast and easy with minimum keystrokes needed to access and edit parameters. A stack-based menu system is quick and intuitive with the most-used menus no more than a couple button pushes away.

Placement of the knobs below the display gives direct access to five on-screen parameters at once, plus five “push” functions at the same time. Dialing in sounds has never been faster or easier.

I/O Monitoring

A front panel LED meter bridge provides instant visual status for the inputs and outputs. The effects layout grid also features an intuitive “Meters” display which shows the input and output levels of each effect block at a glance. Additionally a dedicated Meters menu shows all analog and USB I/O levels for quick and easy troubleshooting of connection mistakes.

Abundant I/O Provides Ultimate Flexibility

DIMENSIONS: Width: 482,6mm Height: 131,1mm Depth: 292,87mm including front handles and rear jacks Weight: 6,87 kg

Expanded I/O

Vastly expanded input and output resources provide for ultimate flexibility. The Axe-Fx III features two instrument inputs: one on the front and one on the back with auto-switching capability. Inserting a plug into the front input jack automatically switches the unit to front input operation. Remove the plug and the unit switches to the rear input. Connect your wireless to the rear input and then plug into the front input to tune (using the new tuner display) or make quick adjustments. Unplug and you’re back to jumping around on stage with your wireless. The front input features the Fractal AudioAuto-Z technology which simulates the input impedance and subsequent pickup loading of typical stomp boxes.

An additional six analog inputs are available: one pair of balanced XLR/1/4″ combo-jacks plus two pairs of balanced 1/4″ inputs.

Analog output capabilities are similarly impressive with four fully independent stereo pairs: Output 1 features both XLR and 1/4” jacks for connection to FOH, monitors or other line level devices. Output 2 features a second set of XLR jacks and outputs 3 and 4 each offer a pair of Humbuster™ 1/4” jacks. Outputs 3 and 4 are designed for unity gain applications such as “the four cable method” or dual stereo inserts and can also be used as general-purpose outputs. Digital audio I/O is comprised of AES and SPDIF inputs and outputs. Clocking options include internal or external via SPDIF/AES input.

Two expression pedal inputs allow for expressive real-time control of parameters. Fractal Audio's FASLINK II™ provides phantom power and bidirectional communications with the FC-6 and FC-12 foot controllers over standard XLR microphone cables. MIDI In, Out and a dedicated Thru provide easy integration with other gear in large stage rigs. Extensive MIDI support along with a dedicated MIDI block allows the Axe-Fx III to be the central hub of a MIDI-based setup.

Input & Output Blocks

Routing flexibility is enhanced by unconstrained placement of input and output blocks anywhere in the routing grid. Want to insert different outboard devices at different parts of the signal path? No problem. Simultaneously process discrete stereo output for acoustic and electric guitars? Easy. Send stereo to front-of-house, plus a true “Wet-Dry-Wet” on stage while recording a DI for re-amping later? No problem! Each output pair also has its own dedicated front panel LEVEL knob for convenient control.



8×8 USB with Superior Performance

The Center of your Music Workstation

A 16-core, 500 MHz microcontroller provides 16 channels of flawless USB audio (8 in, 8 out) allowing the Axe-Fx III to be the center of your music workstation. The audiophile-grade signal path components and converters provide better audio performance than most dedicated USB audio interfaces. With 8×8 channels you can record multiple tracks of processed audio, DI signals, etc., while monitoring backing tracks, auditioning stereo reamps in real-time, and more. A USB audio sound source can even be placed on the grid with its own dedicated block. Windows drivers are included, and the Axe-Fx III requires no driver on a Mac.


Audiophile Quality Signal Path

Fractal Audio has always operated with the belief that every component is critical. In the same way high-quality pickups, cabling, and components are vital in an analog rig, every piece of the Axe-Fx III is purposely designed to provide the utmost in performance and sonic integrity.

The audiophile-quality signal path features Burr-Brown® SoundPlus™ and Analog Devices® op amps, PPS film caps, a high-voltage bipolar power supply for low distortion and maximum headroom, and flagship-quality Cirrus Logic® converters with fully differential input and output circuitry.

A thoughtfully designed multi-layer circuit board features gold plating and extensive ground fill for low EMI and immunity to interference. This impressive level of engineering yields the most pristine sound quality, lowest THD, and lowest noise floor of any product we’ve ever created—by far.

An audiophile-quality signal path produces the most pristine sound quality, lowest THD, and lowest noise floor of any product Fractal Audio has ever created - by far.


Industry-Leading Amp Models, Speaker Simulation, and Effects

State of the Art Amp Models

The power of the Axe-Fx III provides the perfect platform for our state-of-the art Cygnus amp modeling, the most expressive, musical, and accurate we’ve ever created. In comparison to previous models, the amp block has been refined and improved, with features like a new streamlined interface built around the new 5-knob color display system, a new parametric pre-EQ, and four fully independent “Channels” with instant, seamless switching. As always, the preamp and power amp sections are independently modeled in painstaking detail. The results represent the next step forward in what has come to be known as “Fractal-Quality” amp modeling: a benchmark against which an entire industry measures itself.

Speaker Cabs Galore

The Axe-Fx III features our exclusive, proprietary UltraRes™ speaker simulations with over 2200 factory impulse responses (IRs) to choose from including all the IRs from the Axe-Fx II in a convenient “legacy bank” for easy migration. The redesigned Cabinet block features a 4-channel mixer based on our popular Cab-Lab™ software, providing the capability to mix and remix IRs on-the-fly as you would with real mics on a speaker cabinet. Factory content includes selections from the best of today’s IR producers and artists, including Fractal Audio, AustinBuddy, Celestion, ML Sound Lab, Ownhammer, Chris Broderick, John Petrucci, Chris Traynor & James Santiago, Valhallir, York Audio, Dr. Bonkers, and more. An additional 2,048 “User Cab” memories allow you to load Cab Packs (including any of those compatible with the Axe-Fx II) or 3rd party IRs, and a built-in utility allows you to capture and save your own speaker tones (now with 16 “Scratch Pad” locations!) Our celebrated Tone Matching block is also improved, now with the impressive ability to clone the tone of an amp or recording in UltraRes™.

Astounding Effects

The Axe-Fx III is an incredibly versatile multi-FX processor able to reproduce the sound of a huge array of industry-leading stomp boxes and studio effects. Or push into new territory with the ability to design effect sounds never heard before. Most effects can be dialed in with a single knob to make all required settings, or tweaked at the deepest level. We’ve expanded the number and types of effects available from our already impressive inventory. Each preset can contain, for example, four Drive blocks (each with four channels), four Delay blocks (again each with four channels), and so on.

Not content with just repackaging our algorithms, almost all our industry-leading effects have been updated to take advantage of the increased processing power. A dedicated Plex block features up to 8 delay lines in a feedback arrangement for ethereal “shimmer” effects. Our award-winning reverb algorithm has been updated and improved to provide even thicker, smoother reverbs. A new Pitch block with improved pitch detection provides whammy, double-tracking, harmony, detune and more with astounding tracking and fidelity. A new Real-Time Analyzer block provides detailed visual feedback of the audio spectrum. A stereo Looper provides over five minutes of recording time at full resolution with overdub and undo capabilities. And much, much more…

The routing grid has been expanded to six rows and 14 columns to take advantage of the increased power and effects inventory. Put up to six effects in parallel. Create four separate and independent effects chains. If you can dream it, the Axe-Fx III can do it.

Perform Perfectly with Presets, Blocks, Scenes, and Channels

The Power of Channels and Scenes

The Axe-Fx III Mark II stores a whopping 1024 presets, each one equivalent to an entire rig, whether as simple as just an amp, or as complex as a massive pedal-board and multi-amp rack system.

Fractal Audio's “Channel” concept is a revolution in functionality. Each effect block has up to four channels with each channel containing a unique set of parameter values. Channel switching is instantaneous and seamless and can be done manually (via a foot controller, for example) or automatically when changing scenes. Channels can also be switched via MIDI for applications requiring automation.

Channels provide quick, easy parameter switching without the unwanted side-effects of preset changes (due to grid reordering). Set the Amp block so that Channel A is a “Deluxe Verb” model, Channel B is a “Plexi”, Channel C is a “Recto” and Channel D is “FAS Modern”. Then change channels instantly at the touch of a button.

Eight Scenes within each preset store the bypass state and channel for each block. Program each scene to be a different combination of channels and change the channel and state of multiple blocks rapidly at the touch of a button. Like channels, scenes can be switched via MIDI for automation applications.

By using channels and scenes a single preset can be used for an entire song, an entire set or even the entire show.  No tap dancing required.

Future-Proof Technology

Fractal Audio set a new precedent for the industry with the philosophy of free updates. Historically most companies have been content with one or two firmware updates over the life of a product (usually to fix bugs), or even charging a fee for updates. At Fractal Audio we believe a digital audio processor is a platform that grows as our knowledge and expertise grows. Just as personal computers receive frequent updates to improve performance and add features, we steadily release firmware updates to improve the capabilities of our products.

The Axe-Fx II series received no fewer than 29 major (and dozens of minor) firmware upgrades over its life cycle. The Axe-Fx III is designed with the same anti-obsolescence in mind. Our easy-to-use Fractal-Bot utility and robust update technology make firmware updates a breeze. A built-in backup firmware even allows recovery in the event of complications during update (power outage due to lightning storm, roadie tripping over power cord, electrician shutting off breaker, etc.).


World-Class Editor Software

Axe-Edit: Editor for Mac/PC

The Axe-Fx III would not be complete without Axe-Edit, our award-winning editor suite for Mac and PC. Axe-Edit is now presented in glorious hi-definition that scales cleanly to any size display. Veterans will find it very familiar, but more clean and comfortable. It includes a streamlined new interface with controls for all of the latest features of the Axe-Fx III, plus a convenient new “Quick Build” mode that allows you to build presets easily using drag-and-drop templates. Axe-Manage takes control of Presets and User Cabs, and a new Scene Manager takes charge of scene names and settings. Axe-Edit is offered for Windows 7 or newer and Mac OS X 10.9 or newer.
