Instruction Manual

switch, and the manual describes the two positions as “sine-wave and square-wave sweep”. These terms are
somewhat misleading in that the hardware does not really produce either sine waves or square waves. When
the switch is in the sine wave position, the Sweep Generator oscillator actually produces a triangle wave.
When the switch is in the other position, the oscillator produces a square wave. However, subsequent filtering
circuitry, and the sluggish response of the phase shifters themselves, round off the corners of the square
wave fairly drastically. At higher rates the so-called square wave becomes a somewhat warped triangle wave.
All of these quirks are faithfully reproduced by PhaseTwo.
Phasor A
Phasor A is the first phase shifter. Its input is always connected to the plug-in’s left input and its output is
always connected to the plug-in’s left output. (In a mono context, Phasor A is connected to the plug-in’s only
input and output.)
6 The DEPTH knob determines the range over which the phasing effect varies. If the DEPTH knob is
rotated fully counter-clockwise, the effect moves through a small range of frequencies. As you turn this knob
clockwise, you’ll hear the phase shifter sweep up and down over a wider frequency range (assuming that you
have its SWEEP switch set to GEN 1—there’s more about this switch below).
The Bi-Phase manual makes the following suggestion about setting this control:
At lower speeds, the smoothest-sounding phasing is found at about “8”; as the rate is increased, it will
probably be necessary to reduce the depth somewhat to maintain a smooth-sounding phasing effect,
although this is a matter of taste and what effect you are looking for.
7 The FEEDBACK knob adds a variable amount of the phase shifter’s output back into its input. This
produces resonant peaks in the phase shifter’s frequency response, between the notches that it produces.
These peaks cause the phase-shifting effect to become more pronounced and somewhat more synthesizer-
like. If the knob is rotated fully counter-clockwise, no feedback is added. As you rotate the knob clockwise,
the amount of feedback increases. When rotated fully clockwise, you may hear a ringing effect as the resonant
peaks coincide with harmonics in the signal passing through the phase shifter.
