Wet/Dry The amount of the stereo reverberator (wet) signal relative to the original input (dry)
signal to be output. The dry signal is not affected by the Bass Gain control. The wet signal
is affected by the Bass Gain control and by all the other reverberator controls. The balance
between wet and dry signals is an extremely important factor in achieving a good mix.
Emphasizing the wet signal gives the effect of more reverberation and of greater distance
from the source.
Out Gain The overall output level for the reverberation effect, and controls the level for both the wet
and dry signal paths.
Decay Time The reverberation decay time (mid-band "RT60"), the time required before the
reverberation has died away to 60dB below its "running" level. Adjust decay time
according to the tempo and articulation of the music and to taste.
HF Damping Adjusts low pass Þlters in the reverberator so that high frequencies die away more quickly
than mid and low frequencies. This shapes the reverberation for a more natural, more
acoustically accurate sound.
Bass Gain Shapes the overall reverberation signal's bass content, but does not modify the decay time.
Reduce the bass for a less muddy sound, raise it slightly for a more natural acoustic effect.
Room Size Choosing an appropriate room size is very important in getting a good reverberation
effect. For impulsive sources, such as percussion instruments or plucked strings, increase
the size setting until discrete early reßections become audible, and then back it off slightly.
For slower, softer music, use the largest size possible. At lower settings, Room Size leads
to coloration, especially if the Decay Time is set too high.
Pre Dly Introducing predelay creates a gap of silence between that allows the dry signal to stand
out with greater clarity and intelligibility against the reverberant background. This is
especially helpful with vocal or classical music.
Build Time Similar to predelay, but more complex, larger values of Build Time slow down the
building up of reverberation and can extend the build up process. Experiment with Build
Time and Build Env and use them to optimize the early details of reverberation. A Build
Time of 0ms and a Build Env of 50% is a good default setting that yields a fast arriving,
maximally dense reverberation.
Build Env When Build Time has been set to greater than about 80ms, Build Env begins to have an
audible inßuence on the early unfolding of the reverberation process. For lower density
reverberation that starts cleanly and impulsively, use a setting of 0%. For the highest
density reverberation, and for extension of the build up period, use a setting of 50%. For
