User Manual

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.
