PHASER Function
The PHASER I/O parameter determines whether the Phaser is active for
the current preset.
The DEPTH parameter determines the modulation depth of the phase
shift effect. Higher parameter settings result in the sweep of the filtering
effect occurring over a wider frequency range.
The RATE parameter deterrnines the speed at which the phase shifted
signal is modulated.
The RESONANCE parameter adds feedback to the Phaser so that it has
a more pronounced effect.
The STAGES parameter determines how many stages of phase shift are
to be active. A parameter setting of "4" produces a result similar to a
vintage Phase 90, while a setting of "6" emulates other phaser pedals.
The PHASER function is available only in configurations displaying "PHAS" in the
configuration title.
Phase shifting involves splitting the input signal into two signals, then shifting the
phase of different frequencies of one signal and mixing it back with the original signal.
