Rvrb Time is the RT60—the time it takes for the reverb to decay to 60 dB below its initial
level—in seconds. It is accurate assuming that several other parameters (HF Damping, Di
Scale, Size Scale, and Density) are at their nominal levels. It is adjustable up to “Inf”, which
creates an innitely-sustaining reverb.
LateRvbTim adjusts the basic decay time of the late portion of the reverb after diusion.
L Pre Dly and R Pre Dly (Pre-Delay) is the time between the start of a sound and the output
of the rst reverb reections from that sound. Longer pre-delays can help make larger spaces
sound more realistic. Longer times can also help improve the clarity of a mix by separating
the reverb signal from the dry signal, so the dry signal is not obscured. You can set a separate
time for the left and right reverb signals using L Pre Dly and R Pre Dly.
EarRef Lvl adjusts the mix level of the early-reection portion of eects which oer early
reections.
Late Lvl adjusts the mix level of the late-reverb portion of eects which oer early
reections.
Di Scale scales the “diusion“ of the early reections, that is, how spread out they are as a
group over time. At very low settings, the early reections start to sound quite discrete, and
at higher settings the early reections are seamless. It is adjustable from 0.00 to 2.00, with
1.00 being nominal for the given Room Type.
Density controls how tightly the early reections are packed in time. Low Density settings
group the early reections close together, while higher values spread the reections for a
smoother reverb. It is adjustable from 0.00 to 4.00, with 1.00 being nominal (and usually
optimal) for the given Room Type.
Expanse controls the amount of late reverb energy biased toward the edges of the stereo
image. A setting of 0% will bias energy towards the center. Moving away from 0% will bias
energy towards the sides. Positive and negative values will have a dierent character.
Build adjusts the envelope of certain portions of the reverb. Positive values speed up the
envelope, and negative values slow it down.
Size Scale changes the size of the current room. Altering this parameter will change the
reverb time and also cause some coloration of the reverb. It is adjustable from 0.00 to 4.00,
with 1.00 being nominal (and usually optimal) for the given Room Type.
InnDecay, when turned “On”, causes the reverb tail to decay innitely. When it’s “O”,
the decay time is determined by the “Rvrb Time” or “LateRvbTim” parameters. is is a
good parameter to control with a footswitch.
Wet Bal (Wet Balance). Some reverb eects are actually two stereo reverbs in one, with each
one receiving a dierent mono signal. is balances the outputs of the two reverbs—0%
means they are being mixed equally.
