The OSCILLATOR RATE control varies the speed of an Internal
oscillator which may be connected to the control voltage
bus by means of the push-ON/push-OFF switch located Immed
iately beneath It. This oscillator generates a triangular
waveform whose period Is nominally 20 seconds with the
RATE control fully COW (SLOW), and 50 milliseconds with the
RATE control fully CW (FAST). The control Is logarithmic
so that the speed can be easily controlled and set. An
LED (IN) located next to the switch becomes Illuminated
when the oscillator Is connected to the control bus.
This control may be used to control the flanging effect man
ually. A variable brightness LED located Immediately above
the knob gives a visual Indication of the control voltage
magnitude and thus the relative flanging frequency. This
LED Is operative regardless of the control voltage source.
The REMOTE CONTROL connector may be used to connect an
external signal source to the control voltage bus. The
jack Is a standard TIP-RING-SLEEVE, and the method of
connection Is detailed on the page titled "System Inter
connection". The remote control Is enabled by the switch
below the jack, and an LED becomes Illuminated when the
switch Is depressed.
When the push-ON/push-OFF switch Is depressed, the control
voltage Is varied by the amplitude of the audio Input sig
nal. The THRESHOLD control varies the amplitude of the
signal applied to the envelope rectifier. The calibrations
around this control Indicate the approximate signal Input
amplitude required for proper operation of the envelope
follower. The RELEASE control varies the control voltage
decay time following the removal of the Input signal. The
release time varies from several milliseconds (FAST) to
several seconds (SLOW).
