6.4 The Multi-Effect Module 53
and the effect module only delays the input signal. Turning this knob clockwise increases the
amount of signal reflected back at the end of the line. Finally the
Time knob controls the length of
the delay lines and therefore the delay between echoes.
6.4.2 Chorus
The Multi-Effect module includes both a mono and stereo chorus effect. The chorus 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 .
6.4.3 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 Vibrato
The vibrato effect introduces a periodic low frequency pitch modulation in the signal.
The Rate knob is used to set the frequency of the vibrato effect when the Sync function is off .
The Depth knob enables one to control the depth of the effect, or in other words the amplitude of
the frequency variations. In its leftmost position, there is no vibrato and turning the knob clockwise
increases the amount of pitch variation. The
Mix knob is used to determine the proportion of “dry”
and “wet” signals in the output signal from the effect. In its leftmost position, the output is “dry”,
turning the knob clockwise increases the amount of “wet” signal until, in its center position, there
is only “wet” signal. Note that turning further the knob clockwise has no effect.
6.4.5 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.
