Axe-Fx II FAQ

THIS PAGE IS UNDER CONSTRUCTION!

In time this page will contain questions and answers regarding the Fractal Audio Axe-Fx II. The content below is for editing purposes only at this time.

ABOUT THE AXE-FX II

What are the differences with Standard/Ultra

• See the AFXII Product Brief.

What are the specifications of the AFXII

• See the AFXII Product Brief.

Where are the units manufactured

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

Are the rack ears removable

• Yes. Source

CONNECTING TO A COMPUTER

Is a MIDI interface required to connect to a computer

• No, an USB connection suffices (MIDI-over-USB). The AFXII itself is an USB-to-MIDI adapter.

MIDI connections can still be used.

Can the digital input be used 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 sample rate for the digital output fixed

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

How is USB supported

• The latency of the "built-in" interface is limited only by the host computer. 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
• In the I/O > MIDI menu set "USB ADAPTER MODE" to ON and it functions as a USB-to-MIDI adapter. Source
• You can edit and simultaneously record through USB. Source
• It cannot connect to a USB stick. Source

How does the unit show up in DAW software

• As a 3-In, 2-Out device. Source

Can it be used for reamping

• The third channel on the USB output (to the computer) is the raw data from the Instrument Input. 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 track if you want to go back later and reamp the track again. Source
• 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

FIRMWARE, SYSTEM

Which programming language is used to code the firmware

• C and assembly. Source

CONNECTING INSTRUMENTS AND AMPS

Why are there no input level knobs at the front

• There are soft Input knobs in the I/O menu. The input levels are controlled via digitally-controlled potentiometer. Source

Does using the front input disable the rear inputs

• No, this is different on the AFXII. Use the menu to select either the front or the rear for Input 1. You can leave everything plugged in. Source

Does the guitar go into the front or rear input

• Always use the front input for guitar, whether wired or wireless. Source

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 are levels set in a 4CM setup

• See the topic about unity gain. Turn both Output knobs at the front fully up. Source

Can it play streamed music

• Yes, connect the player through USB. The signal will be mixed into the output of the AFXII. Adjust the volume on the player. Source

Should a wireless receiver connect to the front or rear input

• Front, to take advantage of the front input's "special sauce" for noise reduction. The rear inputs (both 1 and 2) operate on line level, the front input operates on instrument level.

Which knob controls the level of the headphones output

• Output1 knob. Source

Does it have a memory slot

• No.

USING AXE-EDIT AND OTHER SOFTWARE

Is editing over MIDI (instead of USB) possible

• Yes.

CREATING AND EDITING PRESETS

Do Standard and Ultra presets work

• No. Source1 Source2

How many presets are supported

• 384. Most are ported from the Ultra. Source1

What's the range of the Input Impedance per preset

• 70k - 1Meg. Source

How fast does it change presets

• About 20ms.

ABOUT EFFECTS IN GENERAL'

How does the X/Y function work

• 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 AFXII, 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

• 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
• X/Y switching is nearly instantaneous. Source
• X/Y doesn't support spillover. Source
• On the MFC-101 X is green, Y is Red. Source

AMP BLOCK

How many amp models can it hold

• Very many. Source

Can the names of the amps be edited

• No. Source

How much DSP-capacity uses an amp block

• 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

Where are the Warmth and Thump parameters

• These are removed from the Amp block in the AFXII. Source

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

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

How does the 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.

What amp is: Jose Marshall Mod

• (...)
• This is an AFXII-only amp sim.

CAB BLOCK

Which parameters were added to the cab block

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

What are the advantages of 2048 point cabs

• 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." Source

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 a Speaker Drive parameter.

Source

Does it contain a cab type for acoustic guitar

• No.

How are the user slots managed

• User cab slots is another name for external cab blocks, or impulse responses (IRs). (...)
• The AFXII uses the name of the IR-file (contained in the sysx data) to show on its display with a maximum of 32 characters. Source1 Source2

Does it do "amp-in-the-room" tones

• Use the room simulation controls in the Cab block. These can be used with any IR.

OTHER EFFECTS

Does it have a Bit Crusher effect

• No. Source

Can the Global EQ be turned off

• No. Source

About Delay

• The AFXII adds improvements to the Delay block: a two-band parametric EQ for the wet signal with low-cut and high-cut with adjustable slopes for the cut filters. The EQ stuff is on a separate GUI page with a graphical display. Source
• Delay blocks now have a master feedback that goes to 200% for oscillating delay effects. Source
• Delay types: digital mono, digital stereo, analog mono, analog stereo, mono tape, stereo tape, ping-pong, dual, reverse, sweep, ducking, vintage digital, 2290 w/ mod, ambient stereo
• Supports the X/Y function.

About Drive

• Number of blocks: two. No hopes for more Drive blocks. Source
• Supports the X/Y function.

About Chorus

• Chorus types: digital mono, digital stereo, analog mono, analog stereo, japan ce-2, warm stereo, 80s style, triangle, 8-voice stereo
• The Chorus block of the AFXII models bucket-brigade delay lines (BBD). Source

About Flanger

• Number of blocks: two.
• The Chorus block of the AFXII models bucket-brigade delay lines (BBD). Source
• Flanger types: digital mono, digital stereo, analog mono, analog stereo, thru zero, stereo jet

About Phaser

• Phaser types: digital mono, digital stereo, script 45, script 90, block 90, classic vibe, stereo 8 stage - plus vibe mode

About Pitch

• The Pitch block has a Learn function. Turn it on, play a note and the AFXII knows which note you played. Source

About Reverb

• The AFXII adds improvements to the Reverb block: there are improvements in the tail decay plus a two-band parametric EQ for the wet signal with low-cut and high-cut. The EQ stuff is on a separate GUI page with a graphical display. Source

About Wah

• Number of blocks: two.
• Supports the X/Y function.
• The Wah block of the AFXII models the Fasel Inductor. Source

SPECIAL SOUNDS AND ROUTINGS

Is there a Freeze or Hold effect

• Yes, it's built into the Delay effect. Source

Does it support spillover of delay trails and reverb between presets

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

CONTROLLERS, MODIFIERS

How many external controllers are supported

• 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

PEDALS, SWITCHES, FOOT CONTROLLERS

Can the Quick Control knobs be used 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 switching off the AFXII, the MFC-101 also switches off. Source

How many pedals can be connected directly

One.
