Q: All my presets suddenly sound harsh and bright. What’s going on here?
A: Check the CONFIG page of the Global menu to ensure that the Global Power Amp and Cab Modeling have not
been turned off. If a single preset is affected, make sure you haven’t set the SAG parameter of its AMP block(s)
fully counterclockwise. The Global Graphic EQ may also have an unusual setting.
Q: Many of my presets suddenly sound hollow and phasey. What could cause this?
A: These terms are sometimes used to describe the sound of problems caused when stereo sounds have been
summed to mono. Check the AUDIO page of the I/O menu to ensure that the
OUTPUT1 MODE
and
OUTPUT 2 MODE
are set correctly according to how you are listening to your Axe-Fx II. Listening with headphones while making this
change can also confirm or rule out this possible problem.
Q: The sound is distorted even on what should be “clean” presets.
A:
Check the input and output levels of the Axe-Fx II and check the input levels of any downstream amps/monitors.
See p.
9
for more on how to set levels. Also, try the obvious and turn
DRIVE
even lower on the amp, or consider
adjusting global
AMP GAIN
on the CONFIG page of the GLOBAL menu.
Q: The front panel CLIP LED is coming on. What does this mean?
A:
The two CLIP LEDs indicate whether the D/A converters are being overdriven. See p.
9
for more on how to set
levels. Adjust the output levels of your presets, or reduce the global BOOST/PAD setting for the offending output.
In a pinch, you can also lower the GAIN setting on the Global Graphic EQ.
Q: My screen is blinking EXCESS CPU UTILIZATION! REDUCE LOAD.
A: First, try undoing the last change you made by turning the value wheel in the opposite direction. You can also
return to the grid, navigate around the message, and remove one or more blocks. You can also load a different
preset or reboot the unit. Changing CAB mode to “MONO LO-RES” is also a good solution in many cases.
Q: I am pressing FX BYP, but the state of the selected block will not toggle. What gives?
A:
The BYPASS MODE parameter, available on almost all blocks, has a
modifier
slot to control bypass state. Once
attached to this slot, the modifier assumes total control over the block’s bypass switch. Either utilize the MODIFIER
to change the bypass state, or remove it.
Q: I loaded a preset from a backup and it sounds nothing like it did when I first saved it. What’s wrong?
A:
The most likely scenario is that something else changed: the guitar, the amp, or perhaps the settings of remote-
controllers. It is also possible, however, that the preset in question uses Global Blocks that have changed.
Q: When I play audio from the computer through the Axe-Fx II, the sound is processed by the effects, and I can’t
hear the guitar. What’s wrong?
A:
Change the MAIN INPUT SELECT from USB to ANALOG (IN 1). This will allow you to play along with audio from
the computer.
Q: Can I use the onboard MIDI ports to connect a keyboard/synthesizer/etc. to my computer?
A:
Yes.
Just turn on
USB ADAPTER MODE
in the MIDI page of the I/O menu.
Q: My Axe-Fx is warning me about presets not being installed correctly.
A:
This rare error can be corrected through a series of steps. Visit http://support.fractalaudio
