Input Level
The Input Level slider adjusts the input volume
of the reverb to prevent the possibility of clip-
ping and/or increase the level of the processed
signal.
Wet/Dry
The Wet/Dry slider adjusts the balance between
the dry signal and the effected signal, giving you
control over the depth of the effect. This param-
eter is adjustable from 100% to 0%.
Algorithm
This control selects one of seven reverb algo-
rithms: Hall, Church, Plate, Room 1, Room 2,
Ambience, or Nonlinear. Selecting an algorithm
changes the preset provided for it. Switching the
Size parameter changes characteristics of the al-
gorithm that are not altered by adjusting the de-
cay time and other user-adjustable parameters.
Each of the seven algorithms has a distinctly dif-
ferent character:
Hall A good general purpose concert hall with a
natural character. It is useful over a large range
of size and decay times and with a wide range of
program material. Setting Decay to its maxi-
mum value will produce infinite reverberation.
Church A dense, diffuse space simulating a
church or cathedral with a long decay time,
high diffusion, and some pre-delay.
Plate Simulates the acoustic character of a
metal plate-based reverb. This type of reverb
typically has high initial diffusion and a rela-
tively bright sound, making it particularly good
for certain percussive signals and vocal process-
ing. Plate reverb has the general effect of thick-
ening the initial sound itself.
Room 1 A medium-sized, natural, rich-sounding
room that can be effectively varied in size be-
tween very small and large, with good results.
Room 2 A smaller, brighter reverberant charac-
teristic than Room 1, with a useful adjustment
range that extends to “very small.”
Ambient A transparent response that is useful for
adding a sense of space without adding a lot of
depth or density. Extreme settings can create in-
teresting results.
Nonlinear Produces a reverberation with a natu-
ral buildup and an abrupt cutoff similar to a
gate. This unnatural decay characteristic is par-
ticularly useful on percussion, since it can add
an aggressive characteristic to sounds with
strong attacks.
Size
The Size control, in conjunction with the Algo-
rithm parameter, allows you to adjust the over-
all size of the reverberant space. There are three
sizes: Small, Medium, and Large. The character
of the reverberation changes with each of these
settings (as does the relative value of the Decay
parameter). The Size buttons can be used to vary
the range of a reverb from large to small. Gener-
ally, you should select an algorithm first, and
then choose the size that approximates the size
of the acoustic space that you are trying to cre-
ate.
Diffusion
Diffusion sets the degree to which initial echo
density increases over time. High settings result
in high initial buildup of echo density. Low set-
tings cause low initial buildup. This control in-
teracts with the Size and Decay parameters to af-
