Buchla - 297 Infinite Phase Shifter
- Order number: 190103
The Infinite Phase Shifter is a voltage controllable phaser that works with four to ten filter stages. It comes with its own sweep oscillator for typical cyclic phase effects. If the "Barberpole" function is activated, the effect is as if the frequency notches and comb filter effects are being continuously shifted in only one direction.
The Infinite Phase Shifter shifts the phase of an incoming signal by up to 1800 degrees, depending on the frequency and number of stages selected. The phase-shifted signal can be combined with the original to create comb filter effects. The notch density and depth can be varied by feedback (resonance) and step selection. An extensive sweep oscillator provides the well-known cyclic phase shift effect. The parameters "Phase Shift Center Freq", "Notch", "Sweep Osc Freq", "Sweep Osc Depth" and "Resonance" are voltage controlled and may be equipped with an attenuator. An integrated envelope follower allows the creation of amplitude-dependent effects.
The 297 is capable of creating Barberpole effects, with the phase shift and the resulting filter peaks and notches (seemingly) continuously moving in one direction. The change rate can be varied up to 2.5 octaves per second in both directions and is voltage controllable.
This module is not a 200e series module. The missing "e" in the name and the absence of blue buttons already indicate that the parameters of this module can NOT be stored with the Preset Manager of modules 206e or 225e.

297 Infinite Phase Shifter @Buchla
Pioneering synthesizer design since the mid 1960s with Morton Subotnick and the San Francisco Tape Center, Don Buchla has been responsible for the invention of the sequencer, low pass gate, random voltage generators and the complex oscillator, among others. Shortly before his passing in 2016, his rights were acquired by Australian holding company BEMI (2012-2017) and since 2018 is operated by Eric Fox of Buchla USA, based in Minnesota. Buchla USA offers the whole 200e series catalog and boats, as well as the iconic Music Easel.
