INTRODUCTION

This is a FAQ for the Fractal Audio Axe-Fx (AFXII) II. I copied content from forum messages by Fractal Audio, Fractal forum administrators/moderators and other experienced users (Matman, Javajunkie, Bakerman, Jay Mitchell, Scott Peterson, Don Petersen, Rex, GuitarDojo etc.) and added missing stuff.

This FAQ is not officially supported by Fractal Audio.

Note: THIS FAQ IS STILL UNDER CONSTRUCTION! Only content from the forum is added for now. Bulk content will be migrated from the previous How-Tos and adjusted for the AFXII, after distribution of the Axe-Fx II has begun.

Enjoy your Axe-Fx and have fun.

Alexander van Engelen (Yek)


ABOUT THE AXE-FX II

Does it exactly model existing amps and other effects

What are the differences with Standard/Ultra

See AFXII Product Brief and Fractal Audio website.

What are the technical specifications

AFXII Product Brief

How do the unit and the circuit board look

  1. Circuit board
  2. High resolution picture of the front panel
  3. High resolution picture of the rear panel

Where is it manufactured

All units are made in USA. Source The units are identical for all global regions and support 100-240V.

What are the dimensions

19" x 3,5" x 14". An inch or two deeper than the Standard/Ultra. Source1 Source2 The depth according to the Product Brief is 12" but this is incorrect.

Which poweramp and speakers are used by Fractal Audio to compare the amp models to the real amps

Cliff: "A Mesa 4x12 with my Carvin F1200 power amp. The patches were dry because I do A/B comparisons using an A/B box. I run the cab stereo and put the amp being modeled into one side and the Axe-Fx II into the other side. I run my guitar to the A/B box. One output to the amp and one to the Axe-Fx. Then I can quickly switch back and forth to verify the model is working properly." Source

Are the rack ears removable

Yes. Source

Can I mount it in a rack or rackbag

The Axe-Fx is a 19” 2HE device. It can easily be mounted in a rack or rackbag. If necessary combined with a racked poweramp and/or power conditioner. You can put the rack or bag on a stand such as this or this.

STARTER TIPS

New users: how to get started quickly

How do I make sure everything is set up correctly for the gig

How do I experience the factory presets in the best way

Most factory presets are ported from the Ultra. Source1

CONNECTING TO A COMPUTER

Do I need a MIDI interface to connect to a computer

No, USB suffices (MIDI-over-USB). The AFXII itself is an USB-to-MIDI adapter. MIDI connections can still be used and editing over MIDI is still possible.

Do I need an audio interface to record

No. The AFXII already contains the required circuitry to send a digital signal into the computer over USB. If you're monitoring from the AFXII itself there's no latency. When monitoring the signal from the computer, the latency is determined by the host computer.

Which digital I/O connections are supported

  1. S/PDIF (RCA coaxial)
  2. AES/EBU (XLR)

Can I use the digital input simultaneously with analog inputs and outputs

You can use the digital input with analog Output 1 (and simultaneously digital out). You can use Input 2 and Output 2 while using the digital input. Source

Is the digital sample rate fixed

Yes, at 48kHz. Resampling is handled in software. Source1 Source2 Source3 Source4

How does it use USB

  1. The USB is Audio Class 2.0 compliant. On a Mac you don't need to install any drivers but you do need to install the firmware loader for the USB chip (it is a "soft" processor and downloads its code from the host on start-up). On a PC you also have to install the Audio Class 2.0 drivers. The driver supports ASIO, SRC, etc. etc. You can use the USB just for remote control via Axe-Edit if you want. You don't have to use the audio features. Source
  2. In the I/O > MIDI menu set "USB ADAPTER MODE" to ON and it functions as a USB-to-MIDI adapter. Source
  3. You can edit and simultaneously record through USB. Source
  4. It cannot connect to a USB stick. Source
  5. The Axe-Fx will respond to MIDI events sent over USB. Source
  6. You can update the AFXII over USB. Source

How does the unit show up in a DAW

As a 3-In, 2-Out device. Source

How do I use it for reamping

The 3rd and 4th channels on the USB stream from AFXII to the computer contain the raw data from the Instrument Input. This can be mono or stereo. You record this. You then play this track back into the AFXII and set Input Source to USB. Then tweak until you get the sound you want. When you are happy, record the first two channels which are the processed audio. You can save the raw tracks if you want to go back later and reamp the track again. Source1 Source2

The dry signal level is fixed, and for good reason. When you send that signal back in it is the same as the original signal sent to the grid. This means you don't have to adjust anything when reamping. You simply send the signal back. Source

USING AXE-EDIT

Where do I download Axe-Edit

Axe-Edit product page

Can I use Axe-Edit and the MFC-101 simultaneously

Yes. There's no need (anymore) to use a MIDI Merger.

Where do I find information about the upcoming Axe-Edit 1.0 release

Thread

SYSTEM, FIRMWARE

Where do I download the latest firmware

Fractal Support

How do I update the firmware

You can update it over USB. Source

Do I need to update the presets after updating the firmware

Only if instructed so in the firmware release notes.

How do I reset the unit

Which programming language is used to code the firmware

C and assembly. Source

What happens if Bypass is on

After A/D conversion the signal is routed directly to the D/A converters. Inbetween there's no signal processing. It's like a row of just shunts.

How do backup and restore work

The AFXII contains onboard backup memory.

Does it have a memory slot

No.

Is it bad to switch the power off just like that

Use the front panel knob to switch the unit on or off. Or disconnect the power. As often as you want, it doesn't hurt. Just remember to store your preset changes first, it saves all other changes automatically.

CONNECTING THE INPUT / INSTRUMENTS

How do I connect my guitar

The front panel input uses a proprietary circuit and dedicated A/D converter for low noise. Always use the front input for guitar, whether wired or wireless. Source

The front input does not disable the rear input (different from Standard/Ultra). Use the menu to select either the front or the rear for Input 1. You can leave everything plugged in. Source

The front input impedance is 1 Mohm, or less if Input Impdance is adjusted.

All rear analog inputs are balanced like the onboard XLR outputs. The inputs detect whether the incoming signal is balanced or not.

Do not use speaker cable to connect to the 1/4" inputs.

How do I connect a wireless receiver

The same way as with your guitar: to the front input, to take advantage of the front input's "special sauce" for noise reduction. The rear inputs (both 1 and 2) operate at line level, the front input operates at instrument level.

How do I set it up for two instruments with separate signal routings

How do I set the input level(s)

Instead of knobs on the front panel, there are soft Input knobs in the I/O menu. The input levels are controlled via digitally-controlled potentiometer. These work globally, not per preset. The setting doesn't affect the input gain of the Amp and Drive blocks. Source1 Source2

How do I use it as an external effects processor

How do I use the onboard effects loop (Input 2)

Can I connect a music player

Yes, connect the player to the USB slot. The signal will be mixed into the output signal. Adjust the volume on the player. Source

How do I get my guitar to feedback

CONNECTING THE OUTPUT / AMPLIFYING

How do I get sound from it (basics)

How do I use it with FR amplification

(tube / ss poweramp)

How do I connect it to a mixer

How do I use it with my own preamp or amplifier (4CM)

The AFXII supports unity gain when settings things up for 4CM: Four Cable Method. To obtain unity gain turn both Output knobs on the front panel fully up. Source

How do I use it with my own power amp and speaker cabinet

How do I get mono or stereo output

How do I use the onboard effects loop (Output 2)

How do I set up two separate output feeds

  1. FOH
  2. FR
  3. speaker cabinet

How do I set the output levels and avoid clipping

How do I adjust the overall tone and volume level

How to make my tone cut better through the mix

How does it obtain unity gain

The AFXII has digitally controlled potentiometers before and after the A/D and D/A converters. Therefore it knows what the input and output gains are. It compensates for these gains in the digital path. This allows "unity gain processing". If you set the Output Level knob to maximum you will get out what you put in (assuming the blocks have no gain). So if you were to make a preset with shunts from input to output and you put a 1V signal into the unit you would get 1V out. Source

How do the HumBuster outputs work

The 1/4" outputs have a "remote ground sense" feature. You take a TRS cable and on one end you put a TRS plug and on the other end you put a regular TS plug. On the TS end you tie the ring conductor to ground. Plug the TRS end into the Axe-Fx II. The ground noise of the attached equipment is sensed and added to the output signal thereby cancelling the common-mode noise (hum). This is especially useful when doing the 4CM since that's when you usually get the worst ground loops. Source

How do I adjust the headphones level

Use the Output 1 knob. Source

How do I mute the signal when using the Tuner

How do I deal with noise

See Noise Gate.

CREATING AND EDITING PRESETS

How many presets can I use

384.

Can I load Standard and Ultra presets

No. Source1 Source2

How does the DSP load compare to the Ultra

A patch that uses 94% of the DSP on an Ultra will use around 70% on the AFXII. Source

How do I prevent overloading the DSPs

Can I print the settings of presets

How do I keep my presets organized

How do I use the presets of other users

Does it have a Compare function for presets or effect blocks

No(t) yet. Source Alternatively you can set up two presets, use the X/Y function or use Axe-Edit's Snapshot to compare.

How do I use the Quick Control knobs

You can use them to quickly scroll through presets instead of using the Value Wheel. Source And they can be assigned to any modifiable parameter per patch. Source Or configure them to function as pedals. Source

What's the DIR tab on the main preset screen for

It lists preset names and numbers for quick recall. Source

What's the EFFECT tab on the main preset screen for

How does Input Impedance work

It is a parameter in the layout menu that affects a hardware switch. It can be set to automatic (detects the appropriate setting based on your first effect) or you can set it manually. Source Its range is 70k - 1Meg. Source The input impedance is selectable from a dozen or so values. It is done right at the instrument input using analog switches. Source It changes based on the amp model, however amps are always 1 Meg. If the first active effect is a Drive, for example, the impedance will change based on the Drive model. Source It can be saved per preset. Source The impedance feature will only have an audible effect if you are plugging your guitar directly in. It operates by loading down the guitar's pickups. If you have anything buffering the guitar then you won't be loading the pickups. Source

What are Global Blocks

An effect block can be saved as a Global Block. It then can be linked to from other presets, just like Global Amps. A change to the "master" will affect all linked blocks.

How do I edit presets on the computer

Use Axe-Edit.

How do I create a new preset

How do I make editing easier and faster

How do I use settings from other presets

How do I reset an effect to its defaults

How do I insert more than 12 effects in a preset

How do I add an effect to a preset

What's the advantage of putting an effect in a parallel row

How do I put effects before and after my own preamp or amplifier

What do I need to know about running an effect in mono or stereo

What's the correct Bypass Mode for an effect

How do I correcly set the level of an effect

How do I avoid output clipping

How do I globally control the Bypass Mode of an effect block

How do I insert an external pedal or effect device into my routing

USING PRESETS / PLAYING

How fast does it switch between presets

About 20ms.

Does it support spillover of delay trails and reverb between presets

Yes, in the same way as the 1st-generation units. (...)

How do I use a Master Bypass switch

Can I adjust the levels of presets during play

How do I boost the signal for leads

How do I switch between amps in a preset

How do I adjust effect settings globally to the room

How do I crossfade between effects

How does the X/Y function work

  1. You can set up certain effect blocks to switch between two sets of parameters. For example, with Amp blocks you can have 4 configured amps per preset, of which two can be active. Then use the X/Y knob on the front panel, or an IA switch (toggle) on a MIDI foot controller, to switch between the sets. This essentially doubles the number of those blocks within a preset. X and Y can be the same type of effect, say a RAT drive, but with different parameters. There's no transition between the two. Switching occurs at block level using a MID CC, not on preset level. Source1 Source2 Source3 Source4 Source5 Source6
  2. Cliff: "The idea behind X/Y is that people often have multiple distortion/chorus/delay/etc. pedals on their board but they rarely have more than one on at a time. So rather than creating more instances of effects, which sucks up CPU, have each instance capable of more than one sound." Source
  3. X/Y switching is nearly instantaneous. Source
  4. X/Y doesn't support spillover. Source
  5. On the MFC-101 X is green, Y is Red. Source
  6. The X and Y buttons also double as user-definable Quick-Jump keys, which can be set to open the EDIT menus of any 2 blocks without going through the grid.

AMP BLOCK

How many amp models can it hold

Lots. Source Each preset can have two Amp blocks. There's no impact on the DSP capacity because one of the two AFXII DSPs is devoted entirely to amp modeling. Each Amp block can also use the X/Y feature to switch between sets of parameters.

Can I rename the amp types

No. Source

How much DSP-capacity does an amp block require

One Amp block uses about 40%. One of the two DSPs is dedicated to Amp blocks. So you can run 2 of those. The other DSP is for other effects. Source

Does the amp modeling differ from Standard/Ultra

  1. Yes. It's called G2 and Virtual Vaccuum Modeling modeling. See Fractal Audio website.
  2. A part of it has been ported to Standard/Ultra firmware (firmware 11).
  3. CLiff: "As you listen to clips from modelers what you start to recognize is a certain "stationary" aspect to the tone compared to the every-changing tonality of a tube amp. Another thing is finger response. With a good tube amp you can vary the tone quite a bit just by how you fret the note and attack it. Modelers tend to make every note sound the same. So I tested some hypotheses and came to the conclusion that it's because a real vacuum tube has a transfer function that is not static. The transfer function is dependent on time, frequency and amplitude. Where you really hear it is in the in-between regions where the tube is just starting to distort. At first I tried some dynamic transfer functions but that was a lesson in futility. So then I created the VVT stuff. In VVT there is an actual vacuum-tube replica in software. You enter the values of the resistors and capacitors on the grid, cathode, etc. and it behaves just like a tube complete with Miller effect, cathode memory, etc. The problem is that it requires an obscene amount of horsepower so the only solution was a dedicated DSP. The other big part of the G2 sound is the output transformer modeling. The OT distorts and as it distorts its inductance decreases which changes the bandwidth and loop characteristics." Source

How do I know which cab type to use with an amp

Where is the 8-band EQ positioned in the Amp block

It's fixed in position at the very output. Source

What are Global Amps

(...) It supports 10 Global Amps. You can save Amp block settings to a Global Amp slot without being in that slot already. Source

Do amps still have negative presence

No. However for amps with no negative feedback (damp at 0) it turns into a Hicut parameter. Source

Can I split the preamp and poweramp

Are all amp parameters assignable to MIDI controllers

No. Cliff stated it now has the ability to do that for all parameters so maybe down the road. Source1 Source2

How do I dial in an amp

How do I set the Drive and Master controls

How do I use the Tonestack

How do I use the Boost switch

How do I use the Bright switch

How do I use Presence

How does Input Trim work

Changing the input trim doesn't affect the amount of distortion. This the whole idea. You set the trim to optimize the signal level into the converters. Internally the unit applies the inverse of the trim so that the signal into the grid is constant. In other words, if you put 1V into the input the input to the grid is 1V regardless of the trim setting. Source

What do I need to know about the advanced parameters

  1. Saturation switch: it switches in a zener diode clipping stage right before the tone stack. This is the "Arrendondo Mod". Source
  2. Warmth and Thump: these Standard/Ultra parameters haven been removed from the Amp block in the AFXII. Source

How do I add gain to the amp

What about Standard/Ultra amp types that are not in the list (yet)

Cliff: "The amps I haven't ported yet are because I don't have the real amp yet. I could use theoretical values but I would rather not." Source

Javajunkie: "Plexi2 on Ultra = Plexi 1 w/ different bright cap val, xformer hi freq, and presence freq. I have the values written down. You can do the same with the Plexi normal on the II. From what I understand (and Cliff can correct if I am wrong) - Plexi 1 and 2 are the same models with different default values. Source

Cliff: "As for Eggie... It's just a Blues Jr. with no negative feedback." Source

Which amps are modeled

  1. Below is the lst of modeled amps in the AFXII. Source
  2. Cliff: "Almost all the amps in the AFXII are based on actual amps. The amps I haven't ported yet are because I don't have the real amp yet. I could use theoretical values but I would rather not." Source

CAB BLOCK

How many cab slots does it have

64 factory (stock) cabs. 50 user cab slot for external IRs.

Which new parameters are added to the cab block

Room Level, Room Size, Mic Spacing, Low Cut and High Cut. Source

What are 2048-point IRs good for

Cliff: "Depends on the cab. Certain cabs benefit more than others. I started out with 8192 but didn't hear any difference so couldn't justify wasting all that space and CPU. You can hear it with room mics but the room simulation sounds nearly identical. There are a couple reasons for 2048. Probably most important is that it allows 1024 in stereo mode. To be able to do stereo 1024 requires a 2048 convolution engine. Secondly, some IRs benefit from longer IRs. Better to have the ability and not need it than the converse." Source1 Source2

A stereo cab (LoRes) now uses two 1024 IRs (instead of 512 on Standard/Ultra). Source

Jay Mitchell's comments on 512-, 1024- and 2048-point IRs: Source1 and Source2 and Source3 and Source4.

It's no use converting 1024-point IRs to 2048 since they don't contain the necessary data. You need a WAV-file to convert to 2048. A conversation utility is not yet available.

Where do I find 3rd-party IRs

Sources for 3rd-party IRs:

These companies create and sell high-quality IRs for Standard/Ultra as well as AFXII. You can load these IRs into the user cab slots using Axe-Edit. Some of their IRs are included with the AFXII as stock cabs.

Also included are IRs by Jay Mitchell.

Where is the Drive parameter in the cab block

This parameter has been removed from the Cab block in the AFXII. Instead, the Amp block has dynamic speaker modeling in the Amp block. Source

Does it have a cab type for acoustic guitar

No. But there's a thread on the forum that contains Fishman Aurex IRs (1024-point). And there's an IR available of an acoustic body that has been converted to 2048 points.

How do I manage the user cab slots

User cab slots is another name for external cab blocks, or impulse responses (IRs). (...)

Can I rename cabs in the user cab slots

Yes, using Axe-Edit. The AFXII uses the name contained in the sysex data of the IR-file to show on its display with a maximum of 32 characters. Source1 Source2

Can I make it sound more like an amp in the room

  1. Select a farfield cab type (not close-mic'd).
  2. Set the Mic Type to none, to keep tone colorizing by the mic away.
  3. Use the room simulation controls in the Cab block. These can be used with any IR. It's a special reverb algoritm.

Why are two cab blocks louder than a single one

Bakerman: "It depends on how you're panning. Assuming a mono signal sent to cabs: Stereo cab w/ Pan L and Pan R fully left & right will be the same output level as 2 mono cabs w/ balance L & R. If pans/balances are centered the 2 mono cabs will be 6 dB louder. Balance elsewhere would be between 0 and 6 dB louder, and balance doesn't correspond 1:1 to pan L/R for the same placement. Balances will need to be further toward -50 or 50. Source

How many external controllers can I use

12.

How many steps does the Sequencer have

16.

Can a modifier be set to min and max values

In the AFXII there are MIN and MAX values. These are the actual parameter values. For example, if you want to change the delay time from 500 ms to 700 ms, you simply set MIN to 500 ms and MAX to 700 ms. So 0% corresponds to 500 ms and 100% corresponds to 700 ms. Source

Can it act a MIDI source for MIDI Clock to other devices

No. Source

PEDALS, SWITCHES, FOOT CONTROLLERS

Where do I find tips and tricks for the Fractal Audio MFC-101

MFC-101 HowTos

Can I use the Quick Control knobs as pedals

Yes. Source

What's the purpose of the Rj45 port

Use this to connect the MFC-101, instead of using a MIDI cable. It uses a regular CAT-5 network cable and a propietary protocol. This supports bidirectional communication and phantom power. Source

When using the CAT-5 cable a 9V adapter is no longer needed to provide phantom power. Source1 Source2

When switching off the AFXII, the MFC-101 also switches off. Source

All four pairs are used. The two normally unused pairs are used to carry power and ground. Source
