Section 3 - Effects and Parameters
PARAM. DESCRIPTION
FX Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%.
Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%.
Dry: Balance Controls the left/right positioning of the dry signal in the stereo soundfield. Varies from
-99 (all left) to 99 (all right).
Type Selects the Module's reverb type. Reverbs can be one of ten reverb types or variations,
including Studio Room, Wood Room, Vocal Plate, Concert Hall, Plate Reverb, Chamber,
Cathedral, Arena, Cement Shelter, or Infinite Spring. Each room type has a different decay
range (just as real rooms do), so changing TYPE also changes the decay time of the room.
Gated reverbs can be one of twelve different types, including Flat, Shelf,Decaying Linear,
Decaying Logarithmic, Decaying Exponential, Decaying Sine, Reverse Linear,Reverse
Logarithmic, Reverse Exponential, Reverse Sine, Peaking Linear, and Peaking Exponential.
Density Controls the number of discrete room wall reflections during the early portions of DECAY.
Higher settings produce more reflections while low settings yield fewer initial wall echoes. Use
this control in conjunction with DISPERSION to build or reduce the thickness of the early
reflection clusters heard near the beginning of the reverberation. Varies from 0% to 99%.
Dispersion Controls the distance (time) between the echoes set by DENSITY. If DENSITY is set low and
DISPERSION is set high, the initial room echoes can be heard as discrete echoes followed by
smoother room reverberations. Set DISPERSION low for a dense cluster of reflections during
the early portions of DECAY. Varies from 1 to 5.
Simulates the presence of different room materials by controlling the smoothness of
Diffusion
reverberations through the course of DECAY. Low DIFFUSION settings are great for simulating
hard, flat surfaces like concrete or marble, while higher DIFFUSION settings can be used to
simulate the presence of irregular surfaces in the room such as natural rock masonry or
man-made diffusers. Unlike flat surfaces, these materials reflect (diffuse) the sound in many
directions because of the irregularity of the surfaces themselves. This builds smoothness over
the reverb progression. Ranges from 0% to 99%.
X-Over Selects which crossover type will be used for the Primary and Secondary reverb stages.
Type The two crossover types are High Pass (HP) and Low Pass (LP).
X-Over Selects the Frequency where the crossover begins to function. Ranges from 25Hz to 20kHz.
Frequency
These two Parameters allow the crossover to be turned On or Off for each reverb stage. When
Prim & Secd
Off, that particular reverb stage will be full bandwidth, otherwise its frequency response is
X-Over
limited by the X-Over Type and Frequency Parameters.
Prim & Secd Adjusts how quickly the room absorbs the high-frequency reverberations. In a real room,
Damp things like carpet, draperies, acoustic foam, or other absorptive materials can be used to
dampen the natural high-frequency reverberations of the room. High settings of DAMP cause
the reverberations to darken tonally and become less defined over the course of DECAY. Low
settings cause less dramatic room effects on the tone of the reverberations. Ranges from 1 to 7.
LowPass Appears only in Gated Reverbs. Selects the frequency above which all frequencies are rolled
off. This control can be used to darken the response of bright-sounding gated reverbs. Ranges
from 100 Hz to 8 kHz in the Gated Reverb and from 100 Hz to 20 kHz in the Stereo
Gated Reverb.
Time Appears only in Gated Reverbs. Controls the length of the gated reverb in milliseconds (much
like the DECAY control of a normal reverb). Ranges from 25 milliseconds to 300 milliseconds
(or 500 milliseconds on the Stereo Gated Reverb).
