A sweep control allows you to adjust the range of
the frequency shift. And, keeping in the spirit of
the MOOG modular synthesizers, an integrated
LFO allows you to modulate the sweep control,
allowing for extreme effects.

Controls
LFO Section
Control the LFO using the Amount and Rate
knobs and the Lo/Hi selector switch.
Amount Amount varies the depth of phaser
modulation, from barely perceptible at the full
counterclockwise position, to the full sweep
range of the phaser (full clockwise or “Kill” set-
ting).
Rate Rate determines how fast the LFO oscil-
lates. The LFO light blinks to give a visual indi-
cation of the LFO rate.
Lo/Hi The Lo/Hi switch selects the range of the
Rate control. When the switch is Lo, the Rate
control varies from 0.01 Hz (one cycle every
hundred seconds) to 2.5 Hz (2.5 cycles every
second). When the switch is Hi, the Rate control
varies from 2.5 Hz (2.5 cycles every second) to
250 Hz (two hundred fifty cycles per second).
With such a wide range of rates available, obvi-
ously you’ll need to adjust Rate after you flick
the Lo/Hi switch to get the sound you desire.
Phaser Section
Control the Phaser with the Sweep and Reso-
nance knobs and the 6-Stage/12-Stage switch.
Resonance Resonance adjusts the feedback of
the analog filters. As you add more resonance,
the peaks caused by the filters get sharper and
more noticeable.
Sweep Sweep adjusts the center frequency point
of the filters. Use it in conjunction with Amount
to control the frequencies affected by the
phaser.
Drive
The Drive control sets the input gain.
LED Indicators
Three LEDs provide visual feedback.
Level Level glows green when signal is present.
LFO LFO blinks to show the LFO rate.
Bypass Bypass glows either red (bypassed) or
green (not bypassed) to show whether or not the
effect is in the signal path.
