Stage; Spring Reverb; Gated Reverb - Behringer DDX3216 Operating Manual

ER/REV Bal (0 to 100%)
Use this parameter to adapt the ratio of early reflections and
reverb tail to suit the audio signal processed.
Diffusion (0 to 20)
The Diffusion parameter allows you to edit the density of the
reverb tail.
Size (1 to 50)
Size determines the room size with regard to the early
reflections. The number of early reflections is always the same.
HiShv Cut (0 to 30 dB)
Use this parameter to determine the attenuation of the low-
pass filter wired to the input of the algorithm.

5.2.6 Stage

The Stage algorithm emulates the "Live Concert" character of
a stadium. The early reflections ensure a particularly "live"
atmosphere.
Fig. 5.7: Parameters of Stage algorithm
Decay (2 to 20 s)
The Decay parameter controls the duration of the reverb tail,
which is the time needed for the level of the reverb tail to drop to
-60 dB.
PreDelay (0 to 500 ms)
This parameter controls the delay (in ms), until early reflections
and reverb tail can be heard.
Hi Damp (0 to 100%)
This parameter controls a low-pass filter, which is effective
on the reverb tail only. If used moderately, the filter makes the
reverb sound more natural.
Rev Delay (0 to 500 ms)
This parameter controls the delay between the early reflections
and the reverb tail.
ER/REV Bal (0 to 100%)
Use this parameter to adapt the ratio of early reflections and
reverb tail to suit the audio signal processed.
Diffusion (0 to 20)
The Diffusion parameter allows you to edit the density of the
reverb tail.
Size (1 to 50)
Size determines the room size with regard to the early
reflections. The number of early reflections is always the same.
Stereo Width (0 to 20)
Controls the basic stereo width of the reverb.

5.2.7 Spring Reverb

This algorithm emulates the typical sound of a spring reverb,
which is known from countless guitar amps. However, here you
don't have that shatter sound produced when the amp gets
knocked over.

Decay (2 to 5 s)
The Decay parameter controls the duration of the reverb tail, which
is the time needed for the level of the reverb tail to drop to -60 dB.

PreDelay (0 to 500 ms)
This parameter controls the delay (in ms), until early reflections
and reverb tail can be heard.
Hi Damp (0 to 100%)
This parameter controls a low-pass filter, which is effective
on the reverb tail only. If used moderately, the filter makes the
reverb sound more natural.
HiShv Cut (0 to 30 dB)
Use this parameter to determine the attenuation of the low-
pass filter wired to the input of the algorithm.
Hi Freq (0.2 to 20 kHz)
Controls the cutoff frequency for the HiDec Damp parameter.
HiShv Freq (1 kHz to 10 kHz)
Controls the cutoff frequency of the low-pass filter controlled
with the HiShv Cut parameter.
Stereo Width (0 to 20)
Controls the basic stereo width of the reverb.
Metalres (0 to 20)
This parameter determines the structure of the reverb spring
and controls the reverb attack. Low values emulate a reverb tail
that builds up gradually, while high values make the reverb appear
much faster, and give it a rather metallic character.
This type of reverb, which is cut off abruptly, has become
famous through Phil Collins' "In the air tonight". You can determine
the duration of the reverb tail, the reverb intensity, and the
threshold for the reverb to come in. The effect produced
corresponds to a gate, which is wired pre-output and is controlled
by the reverb input. Hint: when used for rhythmical patterns
(snare), adjust the length so that the reverb is cut off just before
the next crotchet that follows (e. g. bpm = 120, 1/4 note = 0.5 s,
reverb length less than 0.5 s).

Decay (1 to 10 s)
The Decay parameter controls the duration of the reverb tail,
which is the time needed for the level of the reverb tail to drop to
-60 dB.
PreDelay (0 to 500 ms)
This parameter controls the delay (in ms), until early reflections
and reverb tail can be heard.
Hi Damp (0 to 100%)
This parameter controls a low-pass filter, which is effective
on the reverb tail only. If used moderately, the filter makes the
reverb sound more natural.
Gate Threshold (-60 to 0 dB)
This parameter adjusts the threshold for the reverb to come in.
Diffusion (0 to 20)
The Diffusion parameter allows you to edit the density of the
reverb tail.
Gate Hold (50 ms to 1 s)
The Gate Hold parameter determines the time which the gate
stays "open", after the signal has dropped below threshold. Use
this parameter to delay the reverb decay.
Stereo Width (0 to 20)
Controls the basic stereo width of the reverb.
Gate Response (2 to 200 ms)
Controls the gate response time.
