Mu-Tron Bi-Phase

Mu-Tron

The Mu-Tron Bi-Phase is a dual phase shifter invented and marketed by Musictronics USA in the 70s. It has become well-known and well-loved for its 'classic' warm and deep sound, as well as the flexibility of its control and audio-processing capabilities. The Bi-Phase II seeks to accurately reproduce the sound and control layout of the original unit. The Bi-Phase II is all-analog and parts-accurate to the original, as much as is possible.

True-bypass foot-switching for each individual phase channel is built into the pedal. An expression pedal may be connected to the CV PEDAL socket at the rear of the Bi-Phase II. Alternatively, you can connect an external CV signal in the range of 0-5V for controlling the Bi-Phase II from a modular synth or modulation source. Either method – expression pedal or CV – allows controlling of LFO speeds and/or manual sweep of the phase sections.

A compact, modern representation of the legendary Mu-Tron Bi-Phase

The Mu-Tron Bi-Phase is a dual phase shifter invented and marketed by Musictronics USA in the 70s. It has become well-known and well-loved for its 'classic' warm and deep sound, as well as the flexibility of its control and audio-processing capabilities. The all-analog Bi-Phase recreates the creamy HiFi phase of the mythical Musitronics Bi-Phase pedal and packs it into a compact, pedalboard-friendly package. The new and compact Bi Phase is designed to fit into modern day pedal chain as it may be powered by standard power bricks, routes the signal from right to left to allow for easy patching, and an interface which is much more symmetrical and intuitive than the original. This Bi-Phase even retains its "bleed-bypass" onto-electronic switching adding some analog warmth to instruments whilst in bypass mode. This was a highly requested feature by many studio engineers who wished to process overheads and vocals through the unit. Just like the original, there is a pedal input that will allow for real-time control of the phase sweep. It may also be used to control the rates of either phasor to provide the musician utmost expression and "Leslie Speaker" type of sounds.

Features and Improvements:

• Modular optical design which allows for consistency across units.
• Optical bypass foot-switching for each individual phase channel is built into the pedal.
• Original +-15 volt internal operations ensures high headroom and low noise
• Square and sine wave operation
• Pedal control assignable to rate to achieve "Leslie" fast and slow control
• Pedal control is assignable to sweep phasors manually.
• LED (light emitting diode) indicators to show the operating status of effects.
• Routes signal from right to left to be more pedalboard-friendly.
• Operates on standard 9v or 12 v DC (negative center tip, 200mA power port)
• The same LFO synchronization and routing capabilities as the original

Controls:

• Feedback controls the level of phase feedback
• Rate controls the speed of the phase
• Depth controls the intensity of the phase effect
• Shape selects square or sine wave
• Pedal may be assigned to rate, or sweep on either Phasor
