UAD Powered Plug-Ins Manual - 251 - Chapter 20: EMT 250 Electronic Reverberator
Note: Levers 1 and 2 both control the echo time, but these parameters are
not individually exposed for external control surfaces and automation. In-
stead, a single echo time parameter is exposed, and levers 1 and 2 in the
plug-in interface are both updated to match the value.
HF Decay (Lever 3)
Lever 3 controls the high frequency damping in Echo mode. The red LEDs on
left side of lever 3 display the current value; the green LEDs on the right side
of lever 3 are inactive.
Four multipliers are available: x 0.25, x 0.33, x 0.5, and max. Higher values
(upper lever positions) result in more feedback.
Predelay (Lever 4)
Lever 4 is used as a predelay to the echo processor in this mode. The predelay
time is added to the echo times, but not to the HF decay feedback loop. See
“Lever 4 Predelay” on page 243 for more information.
Front/Rear
The Front/Rear Outputs switch is not illuminated in Echo mode (the same
monophonic signal is generated at the front and rear outputs). However, the
Front/Rear Outputs switch has a special function in Echo mode.
In the Front position, the program behaves normally. In the Rear position, the
input to the echo processor is muted, while still allowing the echo output to be
passed. This feature is useful for adding echo to specific passages only, by
flipping the switch to Front when echo is desired. The behavior is identical to
the popular “dub” switch on the Roland RE-201 (
“Echo/Normal” on
page 510 ). See “Front/Rear Outputs” on page 243 for more information.
Space
Space mode is a special reverb program with an extremely long decay time
and linear distribution of the reverberation time with frequency (all frequen-
cies decay at the same rate). Because this condition doesn't exist in nature,
and the program was originally intended for science fiction productions, the
“reverberation in outer space” moniker was derived.
The reverb decay time is approximately 10 seconds in Space mode. Predelay
and Front/Rear are the only adjustable parameters in this program mode.
Note: Levers 1, 2, and 3 have no effect in Space mode.
