54 Parameters
adjust the ratio of “dry” and “wet” signal in the output signal from the module. When the knob is
adjusted in the left position, only the original or “dry” signal is sent to the output while in the right
position only the processed or “wet” signal is sent to the output. The Depth knob is used to control
the amplitude of the effect while the Rate knob is used to fix the modulation frequency of the effect
if the Sync function is off.
6.4.3 Flanger
The Multi-Effect module includes both a mono and stereo flange effect. The flanger effects can
be controlled with the three knobs appearing at the bottom of the module. The Mix knob is used to
adjust the ratio of “dry” and “wet” signal in the output signal from the module. When the knob is
adjusted in the left position, only the original or “dry” signal is sent to the output while in the right
position only the processed or “wet” signal is sent to the output. The Depth knob is used to control
the amplitude of the effect while the Rate knob is used to fix the modulation frequency of the effect
if the Sync function is off.
6.4.4 Phaser
The “phasing” effect colors a signal by removing frequency bands from its spectrum. The effect is
obtained by changing the phase of the incoming signal and adding this new signal to the original.
The phaser effects can be controlled with the three knobs appearing at the bottom of the module.
The Mix knob is used to adjust the ratio of “dry” and “wet” signal in the output signal of the module.
When the knob is adjusted in the left position, only the original or “dry” signal is sent to the output
while in the right position only the processed or “wet” signal is sent to the output. The Depth knob
is used to control the amplitude of the effect while the Rate knob is used to fix the modulation
frequency of the effect when the Sync function is off.
6.4.5 Wah
The Multi-Effect module includes 2 different types of wah effects: wah wah, and auto wah. Both
of them are based on a specially designed bandpass filter with a 12 dB/oct slope. In the wah wah
effect, the center frequency of the bandpass filter varies at a certain rate. In the case of the auto-
wah, the variations of the center frequency is controlled by the amplitude envelope of the incoming
signal.
The Freq knob is used to control the central frequency of the filter. Turning this knob clockwise
increases the center frequency. In the case of the Wah Wah effect, the center frequency will oscillate
around the value fixed by the Freq knob while with the Auto Wah effect, the setting of the Freq will
fix the starting point of the value of the center frequency.
The Depth knob controls the excursion of the center frequency of the filter. In the case of
the Wah Wah effect, this excursion is applied around the value fixed by the Freq knob while in
