Effects Descriptions

Flanger

A flanger is a very short delay line whose output is mixed back together with the original
sound. Mixing the original and delayed signals results in multiple frequency cancella-
tions known as a comb filter. Since the flanger is a type of filter, it works best with
harmonically rich sounds.
A low frequency oscillator is included to slowly change the delay time. This creates a
rich, sweeping effect as the notches move up and down across the frequency range. The
amount of feedback deepens the notches, intensifying the effect. You can invert the
feedback signal by choosing a negative feedback value. Inverting the feedback signal
creates peaks in the notch filter and deepens the effect.
Parameter Description
Initial Delay Sets the initial delay of the flanger in .01 millisecond increments.
This parameter allows you to "tune" the flanger to a specific
frequency range. Range: .01ms to 4ms
Depth Sets how much the LFO affects the delay time. Increases the
animation and amount of the flanging effect. Range 05 to 100%
Rate Sets the speed of the low frequency oscillator which modulates the
delay time of the flanger. Range: .01 Hz to 20Hz
Feedback Controls how much signal is recirculated through the delay line
and increases resonance. Negative values can produce intense
flanging with some signals. Range 0% to 100%
Through Zero On - Adds a short delay to the original signal to simulate the
classic "through-zero" flanger sound, which was originally created
using two tape recorders.
On (out of phase) - Inverts the phase (180°) and adds a delay
to the original signal producing additional phase cancellation.
If the feedback control is set to zero, complete cancellation occurs
when the flanger goes through zero

In order to hear a rich
f
flanging effect, the
original signal must be
mixed in with the flanged
signal. This can be
accomplished using the
Wet/Dry Mix control or
with the Main Send
(when using Aux effects).
