Fractal AXE-FX II Quick reference manual - page 8
LOW/HIGH CUT – Adjusts the cutoff point of first order low/high pass filters.
Increase the Low Cut if the sound is too “bassy” or “boomy.” Decrease the High
Cut for a darker cab tone. Common settings are 80-150 Hz for high pass, and
5-7 kHz for low pass.
PROXIMITY – Causes an increase in bass or low frequency response as proximity
is increased (closer to speaker). Disabled when MIC is set to None.
PROXIMITY FREQ – This allows tuning the frequency range over which the
proximity effect occurs. This parameter appears on the ROOM page for stereo
cabs.
DELAY – Delays the signal up to 1 second. With cab in stereo mode or with
two cab blocks in parallel, delaying one cab relative to the other can achieve
interesting comb filter effects. A common practice in studio recording is to use
multiple mics on a speaker at different distances to intentionally introduce it.
The effect is most pronounced when the cabs are summed to mono.
ROOM LEVEL/SIZE – Determines the level and size of room reverb that is built
into the cab block. Increase to add room ambience to the sound.
MIC SPACING – Increases delay times inside the room reverb by simlating the
distance of the room microphone from the sound source.
AIR - Mixes some of the signal going into the Cab block with the signal leaving
the Cab block.
AIR FREQUENCY – Sets the cutoff frequency of the mixed signal. Increase to
maximum value for a straight mix.
INPUT SELECT – Can be used to run two Cabinet blocks in parallel for stereo
processing by setting one to Left and the other to Right.
Cab Block
CAB – Loads a cabinet impulse response (IR). The older FAS and RW cabs were
recorded with neutral mics. OH, Kalthallen, and the Mix/Producer Pack series
have matching mics included in the IR.
SPEAKER SIZE (NORMAL/HI RES ONLY) – “Scales” the IR to simulate shrinking
or enlarging of the speaker. This effect can be used to shift where the tone sits
in a mix, or to create dramatic effects. Subtle settings (0.9-1.1) will sound most
natural. UltraRes IRs do not support size warping, therefore, this parameter is
disabled for UltraRes cabinets.
MOTOR DRIVE – Models the effect of high power levels on speaker tone.
Simulates the impedance and distortion effects that occur when the speaker is
pushed hard. Be aware this setting adds a little compression as you increase it.
This parameter appears on the ROOM page for stereo cabs.
MIC – Don’t feel that you have to add a mic unless you want to add EQ, which
is basically what you would be doing.
Scott Peterson Tip – When using headphones (I use Audio Technica ATH-
M50) use the Room controls in the cab block to simulate early reflections. It’s
a HUGE aspect usually missed with headphones.
