Phaser; Tremolo; Autopan; Enhancer - Behringer DDX3216 Operating Manual

LFO Speed (0.05 to 20 Hz)
The LFO Speed parameter controls the speed (frequency) of
the modulating signal.
Mod Depth (0 to 100%)
This parameter governs the modulation depth, i. e. the amplitude
of the modulating signal.
Mod Delay (5 to 100 ms)
Mod Delay controls the delay of the modulated signal.

5.2.18 Phaser

This algorithm provides a mono version of the Stereo Phaser
algorithm (see chapter 5.2.13).
Fig. 5.19: Parameters of Phaser algorithm
Stages (2 to 7)
Stages determines the number of phase-shift stages.
Speed (0.1 to 10 Hz)
This parameter controls the LFO frequency and thus the
modulation speed.
Depth (0 to 100 %)
This parameter governs the modulation depth, i.e. the amplitude
of the modulating oscillation.
Feedback (-99 to +99 %)
The Feedback parameter feeds part of the output signal back
to the input.

5.2.19 Tremolo

The tremolo effect was one of the most popular effects during
the 60's, and many guitarists used it especially for ballads. And
today, tremolo is again experiencing great popularity. From a
technical point of view, tremolo is a modulation of the signal
amplitude, i. e. the effect constantly modulates the volume, with
the modulating oscillation being generated by an LFO. Since this
effect is actually an insert effect, we recommend that you route
the effect post-fader, but disable the channel's main routing. In
this way, only the processed signal will be audible via the FX
return path.

Wave (Sine/Tri/Squ)
The Wave parameter defines the type of the modulating
oscillation (sine, triangle, square).
Speed (0.05 to 20 Hz)
This parameter adjusts the frequency of the modulating
oscillation and thus the speed of the amplitude modulation.
Depth (0 to 100%)
Depth governs the modulation depth, i. e. the amplitude of the
modulating oscillation. High values produce a more pronounced
effect.
The Autopan effect produces a constant displacement of the
audio signal with reference to the stereo basis, i. e. the signal
wanders from the left to the right, and vice versa. This effect is
widely used for house and techno tracks, and you should
experiment with both percussive and pad sounds. As this effect
is actually an insert effect, we recommend that you route the
effect post-fader, but disable the channel's main routing. In this
way, only the processed signal will be audible via the FX return
path.
Wave (Sine/Tri/Squ)
The Wave parameter defines the type of the modulating
oscillation (sine, triangle, square).
Speed (0.05 to 20 Hz)
This parameter adjusts the frequency of the modulating
oscillation and thus the panning speed.
Depth (0 to 100%)
Depth governs the modulation depth, i. e. the amplitude of the
modulating oscillation. High values produce a more pronounced
effect.
Enhancers are based on a psychoacoustics' principle, in that
they add artificial harmonics to the original signal, thereby
increasing its presence and transparency. Also, the signal
loudness (the perceived volume level) is raised, without
increasing the actual signal level (at least to a considerably minor
extent). The Enhancer algorithm provides dedicated controls for
the bass and treble ranges, and also includes a noise reduction
(gate). As this effect is actually an insert effect, we recommend
that you route the effect post-fader, but disable the channel's
main routing. In this way, only the processed signal will be audible
via the FX return path.

High-Freq (1 to 14 kHz)
Use this parameter to adjust the cutoff frequency of a high-
pass filter acting on the high frequency range. Signals below
that frequency remain unprocessed.
Bass-Freq (50 to 500 Hz)
This parameter adjusts the cutoff frequency of a low-pass
filter acting on the low frequency range. Signals above that
frequency remain unprocessed.
High-Q (1 to 4)
The High-Q parameter controls the resonance of the high-
pass filter (treble enhancer). High values accentuate the cutoff
frequency.
Bass-Q (1 to 4)
The Bass-Q parameter controls the resonance of the low-
pass filter (bass enhancer). High values accentuate the cutoff
frequency.
Process (0 to 100%)
The Process parameter defines the intensity of the harmonics
generated for the high frequency range.
