STEREO POLYCHORUS XO
ANALOG FLANGE/CHORUS
Congratulations on your purchase of the multi-purpose Stereo Polychorus.
Carefully reading these instructions will ensure full use of the tremendous
variety of superb effects, which have been engineered into this state-of-the-
art device.
WARNING: Your Stereo Polychorus XO comes equipped with an Electro-
Harmonix 9.6DC-200BI power supply (same as used by Boss® & Ibanez®: 9.6
VDC/200 mA). The Stereo Polychorus XO requires 110 mA at 9VDC with a center-
negative plug. The Stereo Polychorus does not take batteries. Using the wrong
adapter may damage your unit and void the warranty.
The STEREO POLYCHORUS’ s four switch-selectable modes are:
FILTER MATRIX- A comb filter, which creates “chime” effects. In this
mode, you can sweep the TUNE knob manually for “custom” flanging. FLANGE A
sweeping comb filter that creates a variety of modulation effects and
whooshing sounds.
CHORUS- A sweeping echo for moving sounds such as “12 string guitar” and
rotating speaker effects.
DOUBLE TRACK- A short-delay echo for spacious “stage effects”.
Plug the supplied AC adapter supplied into your Polychorus. Connect your
instrument or microphone to the INPUT jack and your amplifier to the MAIN OUT
jack (for an amazing stereo effect, connect a second amplifier to OUTPUT 2
simultaneously).
Press the BYPASS FOOTSWITCH to engage the effect. The status LED located above
the footswitch will light up. Press the footswitch again to switch back to
bypass mode, the LED shuts off.
FILTER MATRIX – Select FILTER MATRIX mode. The TUNE control will shift
the effect from a high airy tone clockwise (CW) to a rich tone
counterclockwise (CCW). While the RATE control has no effect in this mode,
turning the TUNE control will produce a manual or “custom” flange. The
FEEDBACK control determines how much of the processed signal is mixed in or
“fed back” to the input. In FILTER MATRIX, turning FEEDBACK CW will “sharpen”
or increase the intensity of the effect. CAUTION: In the extreme CW position
the FEEDBACK control may cause oscillation, a squealing or roaring sound. This
is normal and may be stopped by backing off the FEEDBACK control.
FLANGE – Turn the MODE switch to the FLANGE position. The RATE control
determines how fast the comb filter sweeps up and down through its pitch
range. Turned fully CW, the frequency is about ten cycles per second. Turned
fully CCW, the sweep is slow, about one cycle every ten seconds. The pitch
range of the sweep is set by the combined action of the WIDTH and TUNE knobs:
The TUNE control sets the center frequency, and the WIDTH control determines
how far the sweep goes. Maximum TUNE range is obtained by setting the WIDTH
knob fully CW. The FEEDBACK knob also operates as in FILTER MATRIX.
CHORUS – When CHORUS mode is selected, the FEEDBACK knob determines the
number of echoes: CCW for a single repeat, CW for more. The TUNE control will
increase the delay time of the echo as it is turned CW. The WIDTH control
maximizes the delay range of the TUNE control in its CW position and
emphasizes the modulating character of the CHORUS effect as it is turned more
CW. The RATE control operates as in FLANGE.
DOUBLE TRACK In this mode, all controls operate as in CHORUS mode,
except that this is purely an echo effect and the RATE control is disengaged.
SWEEP FILTER When set to ON, gives a smoother well rounded sound with a
“liquid” sensation, if you set your unit to a very slow flange effect it is
recommended to turn this off.
MAIN OUT & OUTPUT 2 MAIN OUT is for standard effect usage. For a total
spacious stereo effect, connect OUTPUT 2 to a second amplifier or a second
channel on the same amplifier.
9V PWR JACK Connect the output plug of the supplied AC Adapter into the
9V power jack at the top of the Stereo Polychorus. The Stereo Polychorus draws
110 mA of current from 9 VDC. The polarity of the power jack is center
negative. The maximum allowable power supply voltage is 12.0 VDC.
Use the following diagrams to quickly set up several of the basic dramatic
effects of the STEREO POLYCHORUS. When you have created these sounds, you will
be ready to tailor your own special settings of the STEREO POLYCHORUS’ s
many possibilities.
