Introduction (original FM9)

Press Release


Industry Leading Tone and FX in our Most Powerful Floor Unit Ever


Plaistow, NH – August 27, 2021 – FOR IMMEDIATE RELEASE: The new FM9 from Fractal Audio Systems is an all-in-one amp modeler, effects processor, foot controller, audio interface—and more—designed for professional use and personal enjoyment. With four DSP cores, the FM9 is the most powerful floor unit ever produced by Fractal Audio, and it features an impressive list of technologies and features from the award-winning Axe-Fx III, FM3, and FC Controllers. Highlights include our industry-leading amp modeling, UltraResTM IR speaker cab simulation, a suite of stompbox and studio effects, expandable FC foot switching, incredibly flexible I/O, 8x8 USB audio interface capabilities, a world-class Mac/PC editor, and more.

The centerpiece of the FM9 is “Cygnus”, the latest version of Fractal Audio’s critically acclaimed amp modeling technology. Cygnus uses Fractal’s proprietary SpectrumTrackTM technology, which improves the response of amp models across the entire range of input levels, especially for amps with cascaded gain stages. The result is truer and more dynamic “voicing,” remarkable touch sensitivity, and exceptionally satisfying “chugs.” The FM9’s two amp blocks each have four channels which can run any of 280+ vintage, modern, and original models covering everything from pristine clean, edge of breakup, and crunchy overdrive, to modern distortion, and insane gain. The FM9 also includes the entire Ultra-ResTM cab collection from the Axe-Fx III, with 2,200+ “Factory” cabs including selections from the today’s best producers, plus 1,024 “User” locations for loading your own Impulse Responses (“IRs”).

The FM9 is an outstanding multi-effects unit, packed with hundreds of incredible stomp box and studio effects, featuring accurate recreations of many classics, plus exciting originals. Selections include 57+ drive pedal models, dozens of delays, numerous choruses, flangers, phasers, tremolo, and other modulation effects, 50+ reverb types from classic spring to real spaces and beyond, multiple compressors, wahs, EQs and filters, a 2-minute looper, an entire suite of pitch effects including detune, harmony, and virtual capo, plus rotary, synth, “plex” effects including shimmer, and much more. With HumbusterTM and unity gain, the FM9 also works great with a traditional rig for “pre” effects, “post” effects, or both at the same time using the “four cable method.”

The FM9 features the same audiophile signal path design as the Axe-Fx III for the utmost in sonic performance and signal integrity. Physically, it is built tough for the road, with a rugged 16-gauge steel chassis and protective endcaps that double as feet. The unit is remarkably easy to use, with intuitive and comfortable controls, plus the same large, full-color main display as the Axe-Fx III and FM3. Nine on-board footswitches, each with its own vari-color LED ring and mini LCD display, provide both tap and hold functions that can be customized to control countless aspects of your rig in realtime. “Footswitch Layouts” provide nine different complete sets of tap and hold functions. At the same time, a FASLINK II port allows connecting up to two Fractal Audio FC-12 or FC-6 foot controllers for extended “pedalboard real estate” or remote control.

The FM9 has numerous inputs and outputs for a great range of different setups. Analog inputs include Fractal Audio’s “Secret Sauce” 1/4” instrument input, plus two separate stereo pairs of balanced 1/4” jacks for use as “aux ins” or “returns.” The main stereo output is equipped with both XLR and 1/4” outs, plus a headphones jack. Two additional independent stereo outputs — one XLR and one 1/4” — can be used as “aux outs” or “sends.” All 1/4” outs feature Fractal Audio’s HumbusterTM technology to help combat noisy ground loops. Digital I/O includes 48k SPDIF in and out, plus 5-pin MIDI In and Out/Thru. Finally, three on-board jacks each allow you to connect an external switch or expression pedal such as the Fractal Audio EV-1 or EV-2.

The FM9 also serves as a high-quality USB Audio interface with 8-channel recording and 8-channel playback capabilities. You can record processed signals, a “DI” for re-amping, and stereo aux ins. Audio can be played back directly to the unit’s outputs (for DAW monitoring or “backing tracks,” for example) or routed through the FM9 for re-amping or for effects processing like a virtual plugin.

FM9-EDIT, a full-featured software editor, is included free. The FM9 is also fully compatible with Fractal-Bot for preset sharing, easy backups/restoration, plus firmware updates in the tradition of continual improvement that has become a hallmark of Fractal Audio.

Above all, the FM9 was designed “by musicians for musicians” to deliver Fractal Audio’s uncompromising signature sound quality, fantastic features, and roadworthy reliability in a highly portable format that musicians are sure to appreciate and enjoy.

"The entire product line was conceived years ago. The goal was to maximize the number of parts shared between products. The footswitch PC boards do three switches each. An FM3 has one board. An FC6 has two. An FM9 has three and an FC12 has four. All products use the same LCDs, encoders, side plates, etc., etc. This reduces cost and repair inventory. The FC6 and the FM3 are basically the same enclosure. The FC12 and FM9 are basically the same enclosure. This isn't a huge market. Margins are thin so you have to think of ways to minimize development and product costs. Parts bin methodology is the route we took on this generation." [3]

You can take the plastic end caps off, but you need to keep air space under the unit and to the sides for airflow.

Model differences

Original FM9

See above.

FM9 Turbo

The FM9 Turbo, or FM9T, was announced in August 2022 and has replaced the first model. It uses two 500MHz processors versus two 450MHz processors in the original version. This provides 10% more CPU power. The Turbo unit looks just like the standard, but shows "TURBO" on the "Splash Screen" when it is booted (the same way Axe-Fx III turbo is distinguished.)

"The original FM9 used the 450MHz version as that was all that was available at the time. The Turbo uses the 500MHz version." [4]

Current FM9 units cannot be converted or upgraded to Turbo models. The size of the mini displays is the same as on the original FM9. All onboard memory is the same; presets are fully cross compatible between the two variants assuming sufficient CPU. The count of presets, blocks, channels, effect types, scenes, layouts, etc. is the same on both variants. Both variants will continue to be fully supported with new firmware, FM9-Edit editor, and other forms of support.

Comparison demo by Leon Todd


The FM9 uses the same processor type (Analog Devices “Griffin” DSP: one ARM and two SHARC+ cores) as the FM3, but two instead of one. [5]

The FM9 Turbo uses two 500MHz SC587 processors versus two 450MHz SC587 processors in the original FM9. The processor speed is displayed in Setup : Utilities : ADC Levels.

"The original FM9 used the 450MHz version as that was all that was available at the time. The Turbo uses the 500MHz version." [6]

Amp modeling, Delay blocks and Reverb blocks run in dedicated DSP cores.

Like the FM3, impulse responses (Cab block) are processed in the accelerator. [7]

"The III uses (1) dual-core Texas Instruments DSP. The FM3 uses (1) dual-core Analog Devices DSP. The FM9 uses (2) dual-core Analog Devices DSPs. The TI DSPs are much more powerful than the Analog Devices DSPs per clock and run at around twice the clock speed as well. So one TI DSP core is about four times more powerful than one Analog Devices DSP core. If we normalize processing power to the III it would be:

  • Axe-Fx III: 100%
  • FM9: 50%
  • FM3: 25%

So why not use the TI DSPs in everything? Power. The TI DSPs use more power and generate more heat requiring active cooling. They are also more complicated to use requiring dedicated clock generation units, multiple power supplies with specific sequencing requirements, etc." [8]

"It has twice the DSP cores of an FM3. Four SHARC+ DSP cores. So it has about twice the processing power. [9]

"FM3 and FM9 use the same SHARC+ family as the QC. FM9 has same number of cores so power should be comparable." [10]

(FM9) "USB is handled by a separate microcontroller (the same micro that the Axe-Fx III uses)." [11]

The internal and ambient temperature is displayed in Setup : Utilities : ADC Levels.


Latency should not increase with CPU load.

"Most blocks do not add latency. The only blocks that add latency are Drive and Amp. The reason being that they oversample and oversampling adds latency." [12]

Comparing the FM9



A single USB driver (for USB Audio and MIDI-over-USB) is required for Windows operating systems. Available here

No driver is required for Mac operating systems.

Note: when using a USB-C to USB adapter on a newer Apple computer, plug the USB-C adapter into a the port on the Mac first, allow it several seconds to “wake up” and then connect a USB cable and FM9 into the adapter.

Boot time

"The progress bar during boot indicates presets being copied from FLASH to RAM. If a preset is empty it is skipped so the more empty presets you have the shorter the boot time." [13]

Press and hold ENTER while the unit powers up to see system startup messages.

I/O connections


Read this:

The FM9 does not have onboard relays but it can transmit MIDI messages to a 3rd party amp or a dedicated relay switcher.

Pedal ports

The FM9 has three pedal ports for direct connecting to expression pedals and/or single external switches.

An expression pedal should have a linear resistance taper, max resistance of 10-100 kOhm, and requires a TRS-to-TRS cable. The pedal must be calibrated before use in the I/O menu.

An external switch can be a momentary or latching one, and uses a TS-to-TS cable (single button switch). Use the I/O menu to tell the hardware what you have connected.

External switches can perform the other or the same tasks as the onboard switches.

The Owner's Manual contains tutorials about connecting, calibrating and configuring a pedal, either connected directly to the device, or via another controller.

The FM9 allows selecting a pedal or switch directly as a modifier source (without assigning it to an external controller first).

The FC-6 and FC-12 foot controllers also allow connecting expression pedals and switches to the controller. These are configured in the Setup > Foot Controllers menu. Read this: FC-6 and FC-12 foot controllers
