Chapter 2 Using the XV-5080 Effects
87: ISOLATOR 2
This adds a filter to the ISOLATOR effect. Isolator is an
equalizer which cuts the volume greatly, allowing you to add
a special effect to the sound by cutting the volume in varying
ranges.

Boost/Cut
Low (Level Low) #
Mid (Level Middle) #
High (Level High) #
These boost and cut the High, Middle, and Low frequency
ranges. At -60 dB, the sound becomes inaudible. 0 dB is
equivalent to the input level of the sound.
Anti Phase Low
Anti Phase Low Sw (Anti Phase Low Switch)
Anti Phase Low Level
Anti Phase Mid
Switch (Anti Phase Middle Switch)
Level (Anti Phase Middle Level)
This turns the Anti-Phase function on and off and sets the
level settings for the Middle and Low frequency ranges.
When turned on, the phases of opposite stereo channels are
reversed and then added. Adjusting these levels for certain
frequencies allows you to lend emphasis to specific parts.
(This is effective only for stereo sources.)
Post Filter
Switch (Filter Switch)
Turns the filter on/off.
Type (Filter Type)
Selects the type of filter.
LPF: Passes frequencies below the cutoff frequency.
BPF: Passes frequencies near the cutoff frequency.
HPF: Passes frequencies above the cutoff frequency.
NOTCH: Passes frequencies other than those near the
cutoff frequency.

Cutoff (Filter Cutoff Frequency)
Sets the filter's cutoff frequency. The closer to zero it is set,
the lower the cutoff frequency becomes; set it closer to 127,
and the cutoff frequency becomes higher.
Resonance (Filter Resonance)
Sets the filter's resonance level. Raising the setting increases
resonance near the cutoff frequency, producing a uniquely
characteristic sound.
Slope (Filter Slope)
Sets the filter's attenuation slope (-24 dB per octave: steep; -
12 dB per octave: gentle).
Gain (Filter Gain)
Compensates for the volume dropped in the cut frequency
range with some filters. The level of compensation increases
as the value is increased, and raise the volume.
Low Boost
Switch (Low Booster Switch)
Specifies whether Low Booster will be used (ON), or not
(OFF). This emphasizes the bottom to create a heavy bass
sound.
Level (Low Boost Level)
Increasing this value gives you a heavier low end.
(Depending on the Isolator and filter settings this effect may
be hard to distinguish.)
Output
Level (Output Level)
Adjusts the output level.
88: STEREO SPECTRUM
This is a stereo spectrum. Spectrum is a type of filter which
modifies the timbre by boosting or cutting the level at
specific frequencies.
