03: ENHANCER
Controls the overtone structure of the high frequencies, adding
sparkle and brightness to the sound.

04: ISOLATOR
This is an equalizer that radically cuts the volume of selected
frequencies, allowing you to create special effects cutting the volume
in various ranges.

Description
These boost and cut each of the
High, Middle, and Low frequency
ranges.
At -60 dB, the sound becomes in-
audible. 0 dB is equivalent to the
input level of the sound.
Settings of the Anti-Phase function
for the Middle frequency ranges.
When turned on, a stereo copy of
the sound is phase-inverted and
added to the signal.
Adjusts the level settings for the
Middle frequency ranges.
Adjusting this level for certain
frequencies allows you to lend
emphasis to specific elements
within a sound. (This is effective
only for stereo source.)
Settings of the Anti-Phase function
for the Low frequency ranges
The parameters are the same as
for the Middle frequency ranges.
Turns Low Booster on/off.
This emphasizes the bottom frequen-
cies to create a heavy bass sound.
Increasing this value gives you a
heavier low end.
* Depending on the Isolator and
filter settings, this effect may be
hard to hear.

05: LOW BOOST

Description
Filter type
Frequency range that will pass
through each filter
LPF: frequencies below the cutoff
BPF: frequencies in the region of
the cutoff
HPF: frequencies above the cutoff
NOTCH: frequencies other than the
region of the cutoff
Amount of attenuation per octave
-36 dB: extremely steep
-24 dB: steep -12 dB: gentle
Cutoff frequency of the filter
Increasing this value will raise the
cutoff frequency.
Filter resonance level
Increasing this value will empha-
size the region near the cutoff fre-
quency.
Amount of boost for the filter output
On/off switch for cyclic change
How the cutoff frequency will be
modulated
TRI: triangle wave
SQR: square wave
SIN: sine wave
SAW1: sawtooth wave (upward)
SAW2: sawtooth wave (downward)
Rate of modulation
Depth of modulation
Speed at which the cutoff frequency
will change
This is effective if Modulation
Wave is SQR, SAW1, or SAW2.
