The Electro-Harmonix Stereo Polyphase is a spectacular phase shifter that uses optocouplers to produce a smooth, liquidy tone that can elevate your playing out of this world. Unlike most phase shifters, the Stereo Polyphase feedback control gives you the ability to vary the sound of the phase shifter, so that you have the final say on the character of the phase shifter’s tone. The Stereo Polyphase allows for optimal user control in three modes of operation. In ENV mode the Stereo Polyphase is a phase shifter controlled by an envelope follower. In LFO mode the Stereo Polyphase is a phase shifter controlled by a low-frequency oscillator. In EXP mode use an expression pedal (not included) to control the phase shifter. You may also use an expression pedal in LFO mode or in ENV mode to control the range of the phase shifter. Hook up the Stereo Polyphase in stereo (each output to a separate amp/mixer channel) for a broad stereo image. Optical circuitry provides a wide dynamic range making the Polyphase ideal for hot output instruments, including keyboards.
