Infinitphase MkII

Infinitphase MKII overview

All new appearance, new PCB layout, improved functionality, lower price!
Imagine the bastard child of an illicit union between a Mutron Biphase and a ZVex Seek Wah, and you'll be imagining something like the infinitphase. However, the infinitphase goes far beyond any existing phaser or sequenced device to offer:

• 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
• an blend of wet and dry signals for subtle phase or outrageous vibrato
• dimensions: 20.5cm W x 15.cm D x 6cm H (to top of knobs): 8" W x 5.9" D x 2.4" H

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.

Custom modifications

A number of modifications to the base model infinitphase are available as optional extras.

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 very similar to a true 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.

LFO speed 1/4" control jack
LFO depth 1/4" control jack
phase-step range 1/4" control jack
One, two or three 1/4" jacks can be added for external control of LFO speed, LFO depth and phase-step range control via either a volume pedal or expression pedal

4/8 phase stage toggle switch
A toggle switch selecting between 4 and 8 phase stages is added for this mod.

LFO height control
This mod consists of an extra control added to the rear of the infinitphase with which it is possible to adjust the centre frequency around which phasing occurs. This allows selection of phasing over lower frequencies only or higher frequencies only, or anywhere inbetween. On non-modded infinitphases the centre frequency is adjusted during the final stage of testing for optimum sweep range in conjunction with the depth control.

UPDATED! S&H LFO mod (with engage switch and rate control)
A toggle switch is added to allow selection of the internal step phase voltagesLFO, or the control voltages produced by a classic S&H circuit; a 'rate' control is also added to allow control over the rate of change of the random effect. This mod produces a close approximation of 'classic' sample-and-hold-type sounds, while still allowing the user to retain full control over the nature of the phase/filtered tones produced. When blended with the internal triangle or square waveforms via the CV mix control, many new and wonderful sounds are possible!

NEW! Expression pedal sweep mod
A 1/4" jack is added to which an expression pedal (Boss EV5) can be connected, allowing foot control over the sweep of the phase. A toggle switch is also added to allow selection of the internal tri/sqr LFO, or the expression pedal sweep; or you can choose to have the sweep pedal work all the time it is inserted into the control jack. Note that only ONE of the pseudo-random or expression pedal mods can be incorporated into each infinitphase.
