As tracks are overdubbed and doubled, there tends to be a build-up of midrange in the
presence region—from 2kHz to 8kHz. It tends to impart a "whistling" sort of sound to a
recording. The
IMF
is a notch

lter speci
fi
cally designed to clean up the whistle on electric
guitar tracks, but it works well to tame cymbals, keyboards and vocals as well. Click in the
LISTEN
button to hear exactly where you're tuning the
fi
lter. Set the center frequency of
the notch
fi
lter by adjusting
FREQUENCY
to the spot where the whistle is most annoying,
and then turn

OCTAVE RANGE
control
to also remove the whistle frequency's upper harmonic by setting it to 2. Remove both the
upper harmonic and the subharmonic by setting it to 3. You'll have to play with this control
to get the result you want.
The
HF COMPENSATION
is a gentle shelf boost starting at the center frequency of the
notch to restore some life to the high end.
ENABLE
inserts the IMF into the signal path. Be
sure to pop out the LISTEN button when you're done unless you want things to sound like a
broken iPhone. The IMF only has controls on the front panel, thank the Lord above.
FDR - FREQUENCY DEPENDENT REDUCTION SECTION
On the back side only, you have access to a nifty compressor that can be tuned to reduce
the gain of a small range of frequencies. Think of it as a cut only parametric eq with a
threshold control on it. It works great to keep chugging guitar parts from taking over your
mix, or taming resonant notes on a bass, etc. The
FREQUENCY
control selects the center
frequency, from 20Hz up to 600hz.
BANDWIDTH
lets you select how wide an area is

THRESHOLD
slider down to kick the compressor in—a red LED bar will
