Bi-Phase

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 it’s ‘classic’ warm and deep sound, as well as the flexibility of it’s control and audio-processing capabilities. The Bi-Phase seeks to accurately reproduce the sound and control layout of the original unit. The Bi-Phase 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. Alternatively, you can connect an external CV signal in the range of 0-5V for controlling the Bi-Phase 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.
