PHASER

NOTE: The phaser effect is strongest when Mix is set to 50.
PHASER CLASSES:
Vocal
The Vocal Phaser is a traditional 5-notch phaser with the addition of dynamics sensing, which can be used to
fade the effect in and out when the Threshold level is crossed. Threshold is set with the Special parameter
and Decay sets the effect's fade times.
Instrument
An Instrument Phaser recreates the sound of the "classic" 2-notch phaser, like the MXR Phase 90 . Bandwidth
and LFO parameters are controlled to produce the characteristic sound and control action. For example, as
LFO Speed is increased, Width is automatically adjusted within a musical range.
Concert
The Concert Phaser creates a 5-notch studio phaser, like the MXR Phase 100 . It's the full-blown effect with
extended bandwidth and less linking between LFO Width and Speed.
Gated
The Gated Phaser is the 2-notch Instrument Phaser with the addition of dynamics sensing, which can be
used to duck the effect in and out depending on the Threshold level. Threshold is set with the Special
parameter.
Ambient
The Ambient Phaser is a "spatial" effect that can phase the difference information in a stereo mix. Difference
information is the part of a mix that does not occur equally in both of the stereo channels, often such as
guitars, backing vocals, and reverb tails. Instruments like lead vocals, bass, and some drums are often mixed
to the center, creating the common information (common between the left and right channels). This algorithm
processes either the difference information or the full mix (consisting of both difference and common
information), depending on the Difference Factor setting (see the Special parameter below). Try Factory
Preset #48 with your favorite CDs and then on your own stereo tracks or mixes. Due to its stereo nature, this
class is not available in Discrete 4 routing.
The Phaser effect sweeps non-harmonically spaced notches through a
signal's spectrum. The Low Frequency Oscillator (LFO) Speed determines
the sweep rate and the LFO Shape determines the sweep pattern. Some of
the Phaser classes have dynamics sensing, which can use input level to
switch the effect in and out or trigger the LFO.
