• Displaced: The start, center and end levels of the signal (above the threshold) are
offset, resulting in a distortion which is less severe as signal levels cross the threshold.
The center portion of the clipped signal is also softer than in Cut mode.
• Clip Level slider and field: Sets the point (below the clipping threshold of the channel
strip) at which the signal starts clipping.
• Mix slider and field (Extended Parameters area): Sets the balance between dry (original)
and wet (effect) signals.
Clip Distortion
Clip Distortion is a nonlinear distortion effect that produces unpredictable spectra. It can
simulate warm, overdriven tube sounds and can also generate drastic distortions.
Clip Distortion features an unusual combination of serially connected filters. The incoming
signal is amplified by the Drive value, passes through a highpass filter, and is then
subjected to nonlinear distortion. Following the distortion, the signal passes through a
lowpass filter. The effect signal is then recombined with the original signal and this mixed
signal is sent through a further lowpass filter. All three filters have a slope of 6 dB/octave.
This unique combination of filters allows for gaps in the frequency spectra that can sound
quite good with this sort of nonlinear distortion.
• Drive slider and field: Sets the amount of gain applied to the input signal. After being
amplified by the Drive value, the signal passes through a highpass filter.
• Tone slider and field: Sets the cutoff frequency (in Hertz) of the highpass filter.
• Clip Circuit display: Shows the impact of all parameters, with the exception of the High
Shelving filter parameters.
• Symmetry slider and field: Sets the amount of nonlinear (asymmetrical) distortion applied
to the signal.
• Clip Filter slider and field: Sets the cutoff frequency (in Hertz) of the first lowpass filter.
