ARTURIA – Matrix-12 V – USER MANUAL

4.3.2
Dual-stage Phaser
The following parameters are available independently for both Stage 1 and Stage
2:
Rate: Sets the speed of the phaser
Depth: Sets the depth of the phaser activity
Feedback: Controls the amount of phaser resonance
Shape: Sine vs. noise
Stages 1 and 2 share these parameters:
Sync: Locks both stages to the current tempo of the DAW and/or the rate of the
delay. (These are the only two FX modules with a Sync button.)
Mode: “Single” means Stage 1 is on the left side and Stage 2 is on the right. With
“Dual” both stages process both sides; the Phaser output is mono.
Mix: Alters wet/dry mix
The phase shifter was one of the most popular effects used with electric instruments
in the 1970s. It works by splitting the incoming signal, changing the phase of one
side, and recombining it with the unaffected signal. This creates a notch-comb filter
which can be swept through the frequency spectrum, causing the signature
“whooshing” sound of the phase shifter.
The sweep is caused when the phase of the affected half is modulated by an
oscillator, with the frequency determined by the Rate control. The Depth knob sets
the amplitude for the action of the filtering, while Feedback amplifies certain
harmonics.
