 Model Prophecysound Systems Infinitphase
 Description Prophecysound Systems Infinitphase mk2 phasor sequencer effects pedal

Fully working and in very good condition with minor marks and one scratch in the side panel, see photos. Comes with correct UK voltage AC power supply and a copy of the manual.

It will not work with a normal guitar power supply and must be used with the supplied AC power supply.

Imagine the marriage of a phase shifter and analog sequencer, and you'll be imagining something like the infinitphase. The infinitphase's audio section is based on a Mutron Biphase channel (extended to a maximum of 8 phase stages) and, along with the simple yet flexible control section, allows users to emulate traditional phase tones or explore never-before-heard filtering / phase / vibrato / S&H effects.

extended LFO rate variable from .1Hz to 10Hz triangle / sawtooth / square / pulse / blended LFO shapes OR step-phased tones OR a blend of both for phased / filter sounds that are out of this world slew-rate limiting for step-phase control section producing classic sample-and-hold effects or meandering phase tones positive AND negative resonance adjustable via a single control a blend of wet and dry signals for subtle phase or outrageous vibrato AC-powered, internally-regulated +/-15VDC power supply providing a huge amount of headroom for any signal source (guitars / synths / drum machines / etc)

The dimensions of the infinitphase Mk II are: 20.5cm W x 15.cm D x 6cm H (to top of knobs): 8' W x 5.9' D x2.4' H

A brief overview of the 'standard' infinitphase Mk II's controls (more detailed information can be found in the user manual): rate - controls the rate at which the LFO cycles symmetry - controls the rise/fall or mark:space ratio of the LFO shape - pans between triangle and square LFO waveshape depth - adjusts the LFO depth range - determines how many phase depth controls are cycled through by the LFO smooth - adjustable sle-rate limiting of the changes between phase depth control settings cvmix - determine whether the phasing is controlled by the LFO, the phase depth controls, or a blend of both blend - controls the blend of clean / effected audio resonance - selects whether the phased signal is mixed in-phase or out-of-phase with the clean signal phase depth controls - 9 controls that are stepped through by the internal LFO, and which determine the phase depth when selected

This pedal had two factory modifications (done at time of original build) - 4/8 phase stage toggle switch A toggle switch selecting between 4 and 8 phase stages is added for this mod, allows a 'classic' phase tone to be achieved. - LFO speed toggle switch (for pseudo-ring mod sounds)

A toggle switch is added close to the stock rate control for selecting between two LFO speed ranges - normal and high. At high LFO rates the result is sorta like a ring modulator, only the resultant tones are far more tweakable via the multitude of controls on the infinitphase affecting both the character of the modulating voltage control signal and also the characteristics of the processed audio.

It was serviced earlier this year to replace a failed opamp in the input stage.
