Amplitude Modulation
Level:
The
Level
knob determines the amplitude of the stereo
and
Sigma ( )
outputs.
•
Turning the knob anticlockwise will decrease the output amplitude.
•
Turning the knob clockwise will increase the output amplitude.
•
To eliminate any chance of hard clipping that may occur when
parallel sawtooth waves sum with perfect phase alignment, a soft
clipping circuit is implemented and limits the amplitude range to
~10Vpp. This essentially turns the built-in VCA into a voltage-
controlled saturator that can accentuate a nonlinearity of the
sawtooth waveforms.
Level CV:
The
Level CV
input is a bipolar control voltage input for the
Level
parameter.
•
Control voltage is summed with the
Level
knob position.
Level CV Attenuator:
The
Level CV Attenuator
determines the depth of
modulation applied to the
Level
parameter.
•
Turning the knob anticlockwise will decrease the depth of
amplitude modulation if an external signal is present at the
Level CV
input.
•
Turning the knob clockwise will increase the depth of
amplitude modulation if an external signal is present at the
Level CV
input.
