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 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
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
CONNECTING THE OUTPUT / AMPLIFYING
How do I use it with FR amplification
(tube / ss poweramp)
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 set up two separate output feeds
- FOH
- FR
- speaker cabinet
How do I set the output levels and avoid clipping
- The XLR outputs are line-level. Source
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
- Manual page ...
How do I adjust the headphones level
Use the Output 1 knob. Source
How do I mute the signal when using the Tuner
See Noise Gate.
CREATING AND EDITING PRESETS
How many presets can I use
384.
Can I load Standard and Ultra presets
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
- Manual page ...
Can I print the settings of presets
How do I keep my presets organized
How do I use the presets of other users
- Manual page ...
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
- They can be assigned to any modifiable parameter per patch. Source
- Or configure them to function as controllers. Source1 Source2
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
The amps are all 1Meg but if there's an active effect before the amp and it's default impedance is lower the input impedance will switch to that (if configured to "auto"). __________________
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.
