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.
Parameter What it does
Pre-delay Adjusts the time until the first reflection
Early level
Adjusts the balance between early and
later reverb reflections
Hi ratio
Adjusts the reverb time of high frequency
sounds alone
High pass
filter
Adjusts the cut-off frequency of the high
pass filter
Density
Adjusts the density of the Reverb effect
between ‘spacious’ and ‘tight’
Gate
threshold
Adjusts the threshold of the gate effect
Gate hold
time
Adjusts the time it takes until the gate
effect is activated after the signal is over
the threshold
Gate release
time
Adjusts the time it takes for the gate
effect to deactivate after the signal falls
below the threshold
Reverb time
Adjusts the length/time of the reverb
effect
Delay algorithms
Delay effects add a slight (or long) delay to one or both channels
at varying speeds.
Parameter What it does
Delay coarse
Adjusts the delay time of the left and right
channels in 100ms increments
Delay fine
Adjusts the delay time of the left and right
channels in 1ms increments
Feedback
Adjusts the repetition of the left and right
channels
Delay
Adjusts the delay time of the left and right
channels
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.
Parameter What it does
L.F.O.
Sets the modulation speed
Pre-delay
Adjusts the time until the first
modulation
Depth
Adjusts the delay time variation (hence
the depth)
Phase
Determines the phase between
modulation delay 1 and 2
LPF
Adjusts the roll-off frequency of the low
pass filter
Pitch shift
Adjusts the pitch
Modulation mode
Determines the delay time
Wave type
Decides whether sine or triangular
wave types will be used to modulate
the signal
Way
Changes the panning of the effect
between left to right, right to left and
centered to left/right
