Rocktron Xpression - Manual (Page 30)

Functions and Parameter Descriptions
Reverb is a multitude of echos spaced so close together that, to the human
ear, seem as a single continuous sound. These echos gradually decrease in
intensity until they are ultimately absorbed by the boundaries and obstacles
within a room. As the sound waves from the sound source strike the boundaries
of a room, a portion of the energy is reflected away from the obstacle while
another portion is absorbed into it - thereby causing both the continuance of
sound as well as the decaying or “dying out” of the sound.
The PARAMETER SELECT control will allow you to access each of the following
Reverb parameters.
The PARAMETER ADJUST control allows you to adjust the selected parameter:
REVERB
Function
The REV INPUT parameter determines whether the reverb circuit is
active or bypassed for the current preset.
The R-MIX EFFECT/DELAY parameter is used to define the ratio of
direct signal to delayed signal to be input to the reverb section.
The REVERB LEVEL parameter allows you to control the level of the
reverb signal at the output of the Xpression relative to the direct signal
and other effect signals.
The REVERB DECAY parameter determines the length of time that the
reverb signal will sound before it has completely died out.
The REVERB HIGH FREQUENCY DAMPING parameter is used to
control the decay rate of high frequency information in the reverb
signal. Higher parameter settings will result in a faster decay of high
frequency information.
The R>SPILLOVER parameter determines whether reverbs generated
in the current preset will continue decaying when the next preset is
recalled.When switched off, reverbs will be abrubtly cut off when the
next preset is recalled.
REV INPUT
R-MIX EFF/DLY
REVERB LVL
REV DECAY
REV HF DAMP
R>SPILLOVER
Note!
When reverb from the
current preset is spilled
over into the next preset
recalled (SPILLOVER
"ON"), the reverb
parameters for the new
preset will be changed to
match those of the previous
preset (except for the REV
INPUT and SPILLOVER
parameters) - even if the
Reverb effect itself is
switched "OUT" in the
previous preset.
The EFFECT LEVEL
parameter in the next
preset recalled does not
change, therefore reverb
spilled into it may be of
higher or lower volume -
depending on the EFFECT
LEVEL setting in each
preset.
Also, recalling the same
preset twice via MIDI will
cancel the Spillover effect
and reset the new preset to
its stored parameter values
(only when the
SPILLOVER parameter in
the recalled parameter is
set "OFF").
