EFFECT ALGORITHMS AND PARAMETERS

Reverb algorithms
The DFX2000 offers 17 reverb algorithms, each of which is
named to appropriately match the effect the algorithm has on
your audio signal. Cathedral mimics the long, drawn out rever-
beration heard in Cathedrals which is appropriate for individual
instruments. Plate effects simulate plate reverberations and are
appropriate for use with drums and vocals. The Spring reverb
simulates the classic spring reverberation. Large Hall, Room
and Studio reverbs mimic the reverberations that would be pres-
ent in these various sized rooms. Gate Reverb algorithms syn-
thetically cut off the reverberation after a period of time.

Delay algorithms
Delay effects add a slight (or long) delay to one or both channels
at varying speeds.

Modulation and Pitch Shifter effects
There are various types of these effects; Chorus effects will de-
tune the input signal in conjunction with a slight pitch variation,
and is effective for dispersing signals. Flanger effects provide
slight delays and shifts in phasing. With Phaser effects, a sec-
ondary phase-shifted signal is added to the input signal. The
Pitch Shifter effect adjusts the pitch of the signal, commonly used
with vocals. Vibrato effects adjust the pitch (speed) of peak fre-
quencies of a tone and are used commonly used with guitars.
Tremolo effects are also commonly applied to guitar signals, and
involve applying fast or slow variations in the volume. Auto Pan-
ning does exactly what the title suggests: the signal is panned
from left to right and back again repeatedly, making great use of
the ability of stereo.
