R Ctr Freq
The amount of notch depth or bandpass. At -100% there is a complete notch at the center
frequency. At 100% the Þlter response is a peak at the center frequency. 0% is the dry
unaffected signal.
The output gain in decibels (dB) to be applied to the Þnal output.
The phaser output can be added back to its input to increase the phaser resonance (left
and right). Negative values polarity-invert the feedback signal.
The nominal center frequency of the phaser Þlter (left and right). For a true phaser effect
you may want to modulate these parameters by setting up FX Mods.
LFO Rate
L/R Phase
The amount of phaser (wet) signal relative to unaffected (dry) signal as a percent. At
100% the phaser produces a pair of full notches above and below the center frequency.
At 200% the output is a pure all-pass response (no amplitude changes, but phase
changes centered about the center frequency).
The nominal center frequency of the phaser Þlter. When conÞgured for a maximum
notch (Notch/Dry is 100%), the CenterFreq speciÞes the frequency of the peak between
two notches. The LFO modulates the phaser Þlter centered at this frequency.
The rate of the phaser frequency modulating LFO in Hertz.
The depth in cents that the frequency LFO sweeps the phaser Þlter above and below the
center frequency.
The phase difference between the left and right channels of the LFO. A setting of 180
degrees results in one channel being at the minimum frequency while the other channel
is at the maximum.
