AXIOM PHASE-VIBE PV-1
Phase-Vibe PV-1 Analog Four Stage Optical Phase Shifter
The AXiom Phase-Vibe PV-1 is a 100% analog four-stage optical phase shifter that recreates the classic sounds of the most famous phasers of the 1970s, ’80s and beyond (without the low-headroom distortion that those classic JFET- based phasers were/are limited by). It doesn’t stop there, though. The PV-1 gives you extended control over phase sweep SPEED, DEPTH, RESonance (internal feedback level), CENTER frequency and WAVE shape (square to sine to triangle oscillation) and it has a MIX control that lets you dial in anything from a completely dry signal to a pure vibrato effect (that’s the “Vibe” part of the Phase-Vibe). The LEVEL control is configured as an input trim so even the hottest signals won’t overload the circuitry (such as when placed in an amp’s effects loop or after dirt and boost pedals). You can phase shift wide or narrow across all the audible frequencies or center the sweep in the high, mid or low-band. The PV-1 can provide anything from just a hint of texture to an all-out effect for everything from clean funk to electric blues to screaming leads.
- 100% analog circuitry
- Optical phase shifting
- True bypass
LEVEL: Adjusts the volume level by trimming the input signal. Use this to
eliminate distortion when using the PV-1 with high input signal levels such as
in an amp’s effects loop.
MIX: Adjusts the effect gradually from completely dry to maximum phasing
intensity to full vibrato.
RES: Increases the amount of internal ‘resonance’ feedback as the knob is
turned clockwise – from none to maximum intensity (from ‘script’ to beyond
‘block’ levels).
CENTER: Adjusts the frequency center of the phase sweep. Along with the
DEPTH control you can apply the phasing effect to any frequency band the
entire audio frequency spectrum or only the high, mid or low-band.
SPEED: Increases the speed of the phase sweep as the knob is turned
clockwise.
WAVE: Adjusts the shape of the phase oscillation gradually from square
wave to sinusoidal to traditional triangular modulation.
DEPTH: Increases the range of the phase sweep from narrow to full-range
as the knob is turned clockwise.
