when set to 0% and at 200%, the signal is a pure (wet) allpass response. LFO Phaser Twin does not have
Out Gain or feedback parameters.
Figure 10-24 Response of LFO Phaser Twin with Wet/Dry set to 100%.
The Vibrato Phaser algorithm has a couple of interesting twists. The bandwidth of the phaser fi lter can be
adjusted exactly like a parametric EQ fi lter. The built in LFO can be made to run at audio rates by
multiplying the LFO Rate parameter with the Rate Scale parameter. Running the LFO at audio rates
produces strange frequency modulation effects. The In Width controls how the stereo input signal is
routed through the effect. At 100% In Width, left input is processed to the left output, and right to right.
Lower In Width values narrow the input stereo
fi eld until at 0%, the processing is mono. Negative values
reverse left and right channels. The dry signal is not affected by In Width. As described earlier setting Wet/
Dry to 50% will produce a full notch. At -50% Wet/Dry, you get a bandpass.
