V-VERB PRO REV2496
4.2 Concert hall, cathedral, theater
These three effect algorithms are designed exactly the same,
and differ only in the early reflexion pattern of the ER generator.
Fig. 4.2: Effect design for concert hall, cathedral and theater
This algorithm features a very natural, soft reverb tail like you
would hear in large concert hall. The early reflection echograms
are derived from an acoustically superior concert hall that has
been used for many high-quality recordings.
A sound controller is located ahead of this effect.
LO CUT
(low cut filter) determines the frequency of the high pass filter,
and
HI FREQ
(high frequency)/
HI GAIN
(high gain) adjust the
frequency and the lowering of the shelving filter, used for
adjusting high frequencies.
Using
ER/REV
(early reflections/reverb mix), you can adjust
the mix ratio between early reflections and late reverb tail. A
value of 0% creates only early reflections, while the value 100%
creates only the reverb tail.
The parameter
DRY
determines the signal level of the direct
signal, provided that you have activated the INTERNAL mode.
FX
LVL
(effect level) controls the volume of the effect signal.
Together,
DRY
and
FX LVL
control the effect mix ratio.
Using
ER TYPE
(early reflexions type), you can determine the
physical location of a recording microphone that is being used in
a room. Available are BACK, MIDDLE, FRONT (near the sound
source) and BALCON (elevated position). Using
ER SIZE
(early
reflections size), you can increase or decrease the size of the
simulated space.
Using
ER DIFF
(early reflexions diffusion), you can adjust the
diffusion degree for early reflexions. Value 1 makes individual
reflexions clearly audible, while value 30 produces the highest
density. With
ER DLY
(early reflexions predelay), you can further
delay early reflexions (depending on room type, size and
microphone distance).
The
SIZE
(room size) parameter determines the size of the
simulated space for the reverb generator. This parameter also
influences the maximum decay time (RT60) that is adjustable
using the
DECAY
(decay time) parameter. Using the
PREDLY
(reverb predelay) parameter, you can delay the trigger point for
reverb tail.
The
DIFF
(diffusion) parameter determines the reflection density
for reverb tail. Low values increase the transparency, while
high values produce a softer, more dense reverb tail. The
SPREAD
parameter strengthens the room impression.
Just like with decay in real rooms, reverb tail dampens higher
frequencies. The
DAMP
(dampening frequency) parameter
determines the frequency above which dampening kicks in. Decay
time for lower frequencies can also be separately adjusted. This
is done using
BASS
(bass multiply). The BASS value describes
a factor that refers to the decay time determined using
DECAY
(decay time). The
BASS F
(bass frequency) parameter determines
the frequency above which BASS no longer engages.
Reverb tail can be modulated on this page in two different
ways, selectable with
MTYPE
(modulation type). LINEAR creates
chorus-like modulation, while RAND produces random
modulation.
MDEPTH
controls modulation depth, and
MSPEED
controls modulation speed.
CATHEDRAL was optimized for very long decay times. Early
reflections cover many big spaces with different structural
shapes. The design of this effect is identical to CONCERT HALL
and differs from it only in the
ER TYPE
parameter on the second
EDIT page. The following types of spaces are available: CHURCH,
CHAPEL, CATHDR (Cathedral) and CASTLE. The SPREAD
parameter is not available.
The THEATER algorithm is also based on the CONCERT HALL
effect and contributes a surprising degree of liveliness.
Unlike with the CONCERT HALL effect, the following room
types are available for early reflexions (
ER TYPE
, second EDIT
page): THEAT. (Theater), ARENA, CLUB, STADI. (Stadium),
STAGE, STUDIO, OPERA and AMPHI (Amphitheater).
A special feature of this effect is the
ATTACK
parameter that
lets you determine how quickly the reflections in the reverb tail
fade out. Low values produce a sudden fadeout, while high
values result in a gradual fadeout with the highest density.
SPREAD
influences the progression of the reverb tail. Low
values describe a relatively linear curve, while high values create
a less linear curve progression. This lets you create very
interesting decay characteristics.
4.3 Gold Plate
This algorithm is particularly well suited for drums and
percussion. However, singing parts also benefit from the
particularly dense reverb tail. The additional four-fold delay lets
you create your own early reflexion patterns.

With
ER/REV
(early reflexions/reverb mix), you can adjust the
mix ratio between early reflexions and late decay. The
DRY
and
FX LVL
(effect level) parameters control the mix ratio between
the dry signal and effects signal.
DRY
determines the level of the
direct signal (if mix is set to INTERNAL), while
FX LVL
controls
the effect volume.
Using
DECAY
, you determine the decay time, whose maximum
value depends on the reverb room size selected using
SIZE
.
With the
PREDLY
(reverb predelay) parameter, you can delay
the point at which the reverb tail is delayed.
