Controls
Sweep Generator 1
- Rate
- controls the speed/rate of the LFO wave that controls the effect
- Man/Ped
- switches the rate of the LFO between the setting of the Rate knob and the pedal.
- Shape
- switches the LFO between a square and a sine wave
Sweep Generator 2
- Rate
- controls the speed/rate of the LFO wave that controls the effect
- Shape
- switches the LFO between a square and a sine wave
Phasor A
- Depth
- controls the depth/amplitude of the modulation (the size of the range in which the effect sweeps).
- Feedback
- sets the amount of effected signal fed back into the effect (for a stronger effect)
- Sweep (Ped/Gen 1)
- switches the sweep control of the phasor between pedal control and LFO control by Sweep Generator 1
Phasor B
- Depth
- controls the depth/amplitude of the modulation (the size of the range in which the effect sweeps).
- Feedback
- sets the amount of effected signal fed back into the effect (for a stronger effect)
- Sweep Sync (Norm/Rev)
- switches between normal sweep and reverse sweep (if you use the same sweep source as phasor A, phasor B will move in the opposite direction).
- Sweep (Gen 1 / Gen 2 / Ped)
- switches the sweep control of the phasor between pedal control, LFO control by Sweep Generator 1 and LFO control by Sweep Generator 2
- Phasor B Input
- selects a source for Phasor B: input A (same input as Phasor A), output A (Phasor B gets the output of Phasor A as input), input B (separate input for Phasor B)
Information
a Musitronics ad
Because a dual phasor gives you creative effects not possible with two separate phasors. Like super-deep phasing,or stereo phasing, or synchronized phasing of separate instruments.
And that's just for starters.
Add the optional control pedal and the possibilities are limitless.Check it out and let your music fly.
The Mu-tron Bi-phase. From the innovators who brought you the Mu-tron III.
