Isolator (3 Band Isolator)
This effect separates the input sound into three frequency
bands, High, Mid, and Low, and cuts or extracts them.
Low Level, Mid Level, High Level
Value: -60 dB–4 dB
These cut (or increase) each frequency band. At -60 dB,
the sound becomes inaudible. 0 dB is equivalent to the
input level of the sound.
AntiPhase Low MixSw, AntiPhase Mid MixSw
Value: Off, On
This turns the Anti-Phase function on and off for the low
and mid frequency ranges. When turned on, the
counter-channel of stereo sound is inverted and added to
the signal.
AntiPhase Low Level, AntiPhase Mid Level
Value: 0–100
This sets the Anti-Phase level for the low and mid
frequency ranges.The level setting allows you to achieve
the effect of extracting only a particular part. (This is
effective only for stereo source.)
• In this algorithm, the functions of the machines that make
up the basics for remix artists and pro DJs have been
minutely analyzed and reproduced. Whereas with ordinary
equalizers, some sound is still audible even when the gain
is turned all the way down, the Isolator completely cuts off
the sound. By turning this on and off and changing each
level in realtime, you can get the effect of having the sound
of particular parts appear and disappear.
Filter
These filters allow you to modify the frequency response of
the input sound widely and give sound a style.
Type
Sets the type of filter used.
fig.10-6e
Curve
Value: -12 dB/oct, -24 dB/oct
Sets the filter’s attenuation slope (-24 dB per one octave:
steep; -12 dB per one octave: shallow).
Freq (Cutoff Frequency)
Value: 0–100
Sets the filter’s cutoff frequency. Set this closer to zero,
the cutoff frequency becomes lower; set closer to 100,
the cutoff frequency becomes higher.

Explanation
LPF
Low pass filter. Passes frequencies below the
cutoff frequency.
BPF Band pass filter. Passes frequencies near the
cutoff frequency.
HPF High pass filter. Passes frequencies above the
cutoff frequency.
BEF Band eliminate filter. Passes frequencies other
than those near the cutoff frequency.
