STEREO POLYPHASE
PHASE SHIFTER
Congratulations on your purchase of the Stereo Polyphase, an envelope
follower and LFO controlled phase shifter. The 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.
— POWER —
WARNING: Your unit comes equipped with a 24 Volt/100mA AC external power
adapter. Use only the power adapter supplied, and make sure it is appropriate to
your location (USA, Europe, Japan, Australia). Use of the wrong adapter can cause
damage to the unit or to you, and will void the warranty. Connect the included
24VDC/100mA AC Adapter to the Power Jack, located at the top-center of the Stereo
Polyphase.
— CONTROLS —
FEEDBACK Knob – Controls the amount of signal fedback from the output of the phase
shifter circuit back into the input of the phase shifter circuit. As you turn the feedback control
up, the phase shift effect will sound more pronounced and even sound 'peaky' at high settings.
The FEEDBACK knob is always active.
MODE Knob – When set to ENV the phase shifter is controlled by an envelope follower.
When set to LFO the phase shifter is controlled by a low-frequency oscillator. When set to
EXP the phase shifter is controlled by an expression pedal (not included).
