UAD Powered Plug-Ins Manual - 140 - Chapter 12: EMT 250 Electronic Reverberator
Reverb Reverb program mode offers the same all-time classic reverb algorithm that
made the EMT 250 famous.
Decay Time (Lever 1)
Lever 1 controls the main reverb tail decay time. The red LEDs on the left side
of lever 1 indicate the current decay time; the green LEDs on the right side of
lever 1 are inactive.
The decay time range (at 1 kHz) is 0.4s to 4.5s, selectable via 16 steps.
LF Decay (Lever 2)
Lever 2 controls the low frequency decay time (at 300 Hz). The red LEDs on
the left side of lever 2 display the current value; the green LEDs on the right
side of lever 2 are inactive.
Four multipliers are available: x 0.5, x 1.0, x 1.5, and x 2.0. The multiplier
refers to a factor of the main decay time (lever 1). Higher values (upper lever
positions) generally result in more low frequency content in the reverb tail.
HF Decay (Lever 3)
Lever 3 controls the high frequency decay time. The red LEDs on the left side
of lever 3 display the current value; the green LEDs on the right side of lever
3 are inactive.
Four multipliers (at 6 kHz) are available: x 0.25, x 0.33, x 0.5, and max. At
the max position, the HF decay factor is x 1.0 at approximately three sec-
onds. The multiplier refers to a factor of the main decay time (lever 1). Higher
values (upper lever positions) generally result in more high frequency content
in the reverb tail.
Predelay (Lever 4)
Lever 4 is used as a typical reverb predelay parameter. See
“Lever 4 Predelay” on page 137 for more information.
Front/Rear
In Reverb mode, the Front/Rear Outputs switch is illuminated. Changing the
switch setting will yield a slightly different effect. See “Front/Rear Outputs” on
page 137 for more information.
