Notes and suggestions
Reverb Reverberation consists of a series of “waves”, called reflections, which comprise
early-reflections and tail reflections. In the diagram, the early reflections are shown by the
letters a and b while the tail reflections are between c and d:
x = Time
y = Amplitude
x, y = 0
a
b
c
d
The DSP1 of the S Series can operate in two different ways:
• by keeping the distance that separates the early reflections constant, from point x=0 to
point c (reverbs with non- programmable ER);
• by varying the distances that separate the early reflections (reverbs with programmable
ER).
In the reverberation with programmable ER, the distance between x=0 and a is determined
by the “Room Size” parameter. The distance between points c and d is determined by the
“Diffusion” parameter. The harmonic quality of the reflections is obtained by combining the
“Attenuation” parameter with the equalisation filter (“Filter type”, “Filter freq.”).
In reverberation with non-programmable ER, while the distance between points a and c is
fixed, it is possible to edit the distances between x=0 and a with the “Delay” parameters,
between c and d with the “Rev. time” parameter, and the harmonic quality of the reflections
with “H.F.Decay”, “Filter type” and “Filter freq.”.
Types of reverbs In all effect processors (DSP), reverberation has standard names which
indicate the type of “room” simulated (Hall, Room, Concert...). The following is a descrip-
tion of the characteristics of the S Series reverbs:
Hall1, Hall2, Concert Concert hall.
Small Room, Medium Room,
Large Room Recording rooms of progressively larger dimension, respectively.
Vocal Vocal recording rooms with extremely attenuated reflections.
Church Cathedral with a high number of reflections.
Plate Imitation of a plate reverberation consisting of an oscillating metal plate that was very
popular in the past.
Types of modulation DSP2 can produce standard and very different special effects. Here
is a description of the different modulations that can be obtained with the “non standard”
modulations shown in italics:
Delay Repetition of the sound, with decreasing intensity and gradual diminishing of the high
frequencies.
Panecho Delay with alternating repetitions between the two stereo channels.
Dubbing Delay with repetitions on only one stereo channel.
Chorus Duplication of the sound and phasing between the two components. Produces a multiplica-
tion of the sound sources, as occurs in an orchestra section, creating a softer sound.
