3.3.4
COMPONENTS:
Guitar
Axe-Fx II
Guitar Amp with a series effects
loop
1
and built-in or separate
Guitar Speaker(s).
Second Amp for Stereo (opt.)
Global Settings:
Defaults are OK,
since special 4CM presets should
not have AMP or CAB blocks.
I/O Settings :
Set
OUT1 MODE
as
required for mono or stereo
operation.
Notes:
This highly integrated setup allows you to use the Axe-Fx for effects “in front of” your amplifier, and in its
effects loop at the same time, where many effects work best. Head and cab are shown, but combos with an FX loop
work equally well.
Your guitar signal hits the Axe-Fx II first via the MAIN IN (INSTR or IN1/L) to be processed by any blocks you want in
front of the amp—compressor, wah, wah, and the like. Next, at the FX LOOP block , the signal makes a “round trip”
to the real preamp and back. It is then processed by additional blocks—maybe chorus, delay, reverb, etc. The Axe-Fx
II main outs feed your amp’s Return (Power Amp Input) and the amp powers your real speakers. To extend this
configuration for optional stereo, connect OUT1/R to the RETURN of a second amplifier, bypassing that unit’s
preamp altogether.
Using special cables with the Humbuster™ 1/4" outputs of the Axe-Fx II can significantly reduce ground hum. Visit
fractalaudio.com/cables for purchasing options.
The Boost/Pad functions in the I/O:AUDIO menu can also help run the OUT1 and OUT 2 D/A converters at optimum
levels, padding their outputs for even lower noise. To find the right setting, adjust either of these controls upwards
until you light the respective OUT CLIP LED on the front panel, then back off a few dB to prevent further clipping.
You’ll actually hear the noise floor drop as you make these adjustments.
The no-amp/no-cab presets required for this setup are not well-suited for headphone monitoring, as what you hear
in the headphones will not include any power amp or speaker simulations.

Note: If your amp’s effects loop is the PARALLEL type, the chain of post-FX-loop blocks should be mixed to output a wet-only signal.
