DTX900 Owner’s Manual
The DTX900 provides such a wide and extensive variety of
Effect types that it may be difficult to find the desired
Effect type out of the great number that are available. This
is why all the Effect types are divided into convenient
Effect categories.
This section explains the Effect categories and their types.
The Effect Type list described below for each category con-
tains the columns: REV (Reverb), CHO (Chorus), VAR
(Variation), INS (Insertion) and MEF (Master Effect). The
checkmarks indicated in these columns means the Effect
Type is available for each block. These Effect types (with
the checkmarks indicated in each list) can be selected from
the panel controls.
■
COMPRESSOR & EQ
Compressor is an effect commonly used to limit and com-
press the dynamics (softness/loudness) of an audio signal.
For signals that vary widely in dynamics, such as
vocals and guitar parts, it “squeezes” the dynamic range,
effectively making soft sounds louder and loud sounds
softer. When used with gain to boost the overall level, this
creates a more powerful, more consistently high-level
sound. Compression can be used to increase sustain for
electric guitar, smooth out the volume of a vocal, or bring a
drum kit or rhythm pattern further up-front in the mix.
■
LO-FI
This effect intentionally degrades the audio quality of the
input signal via several methods, including lowering of the
sampling frequency.
■
FLANGER & PHASER
The flanger creates a swirling, metallic sound. The phaser
modulates cyclically to add movement and animation to the
sound.
■
DISTORTION
This effect type is used mainly for guitar, adding distortion
with an edge to the sound.
■
WAH
This effect cyclically modulates the tone brightness (cutoff
frequency of a filter). Auto Wah modulates the tone via
LFO, Touch Wah modulates the tone via volume (note-on
velocity) and Pedal Wah modulates the tone the pedal con-
trol.
