Bass
teristics of the phase shifter and peak limiter have
been highly refined though extensive research.
The result of this combination of processing is a
variable amount of low frequency equalization that
slides through a range of shapes and frequencies
continuously as the note is played and decays. The
manner and direction of this dynamic EQ enhances
the note’s apparent depth while limiting the peak
energy level to what is about equal to the unaltered
sound. That means your amp and speakers are not
overloaded even when the sound is greatly magni-
fied.
