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-

-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).

GAIN Knob/OVERLOAD LED – Active ONLY in ENV mode. Controls the sensitivity of

the envelope follower circuit. In ENV mode, an envelope follower controls the phase

shifter. This means that the amplitude of the input signal (your instrument) will

determine the response of the phase shifter. Use the GAIN knob to set the amplitude

of the envelope follower circuit. When the output of the GAIN knob exceeds the

maximum amount of phase shift, the OVERLOAD LED will light up. When you first

begin using the ENV setting, we suggest you turn the GAIN knob up enough so that

the OVERLOAD LED briefly lights up on most of your notes. Please note the

OVERLOAD LED may light up when the mode knob is set to either LED or EXP modes

but the envelope follower will not modulate the phase shifter in these modes.

START Knob – Sets the START point of the phase shifter’s range.

STOP Knob – Sets the STOP point of the phase shifter’s range.

A Note on RANGE of modulation:

The difference between the START and STOP knobs determines the RANGE of

modulation. For maximum RANGE set and START knob to minimum and the STOP

knob to maximum, or vice versa. As you move the START and STOP knobs closer

together, you will decrease the RANGE of modulation. These knobs can also be used

together to voice the phase shifter. If you put both knobs at their minimum positions

and turn them simultaneously to the maximum position, while playing, you will hear

the range of sounds available to you.

A Note on DIRECTION of modulation:

The relative position of the START and STOP knobs also determines the DIRECTION

of modulation. For example, when using the ENV setting, if START is below STOP,

when you pluck a note the phase shifter will jump up from the START position to the

STOP position, then slowly descend back to the START. The opposite will happen if

STOP is set below START.

RATE Knob – Active in LFO mode only. Controls the speed of modulation by adjusting

the LFO’s rate of oscillation.

Toggle Switch – In ENV mode the toggle switch determines the speed at which the

phase shifter reacts to your playing. When set to FAST the envelope follower will

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.

respond quickly to your playing. When set to SLOW the envelope follower will respond slowly to your playing. In LFO mode the toggle switch determines the shape of oscillation. In the UP position the LFO will produce a triangle wave, giving the phase shifter a smooth modulation from the START to STOP settings. In the DOWN position the LFO will produce a square wave oscillation and the phase will jump between the START and the STOP settings.
