UAD Powered Plug-Ins Manual - 303 - Chapter 27: Lexicon 224
Important: When Immediate is off and a program is changed, previously
modified parameter values are lost, unless the settings were saved as a preset
or if the session file was previously saved so it can be recalled.
System Noise
This UAD-only control enables or disables the modeled inherent dy-
namic system noise of the original Lexicon 224 hardware. Disabling
System Noise enables a more modern-sounding (i.e., cleaner) 224.
Click the button to toggle the state; System Noise is active when the
button LED is lit. The default state is ON.
The elements of the modeled System Noise include quantization effects (at in-
put A/D, output D/A, and within the algorithm), zipper/stepping noise when
adjusting parameters, transformer distortion, and the quiescent noise floor.
Zipper/stepping noise when adjusting parameters can be defeated by dis-
abling System Noise. However, zipper/stepping noise in delay modulation
(i.e., Mode Enhancement) can only be reduced, but not completely defeated,
by disabling System Noise.
Note: System Noise is a global (per instance) parameter; its state does not
change when different programs are selected.
Rear Outs The Rear Outs control is available to select the alternate pair when
the algorithm has alternate sonics at outputs B and D. See
“Inputs &
Outputs” on page 296 for an overview of the hardware implemen-
tation.
Rear Outs Notes
• The left/right outputs of the plug-in always reflect hardware outputs A and
C respectively when Rear Outs is inactive, and outputs B and D respectively
when Rear Outs is active.
• Outputs A and C are “recommended” for stereo use (the rear outs are gen-
erally not used in typical applications).
• Outputs A and C are identical to D and B respectively in the following pro-
grams: P2 Vocal Plate A, P5 Percussion Plate A, P8 Constant Density Plate
A, and P9 Chorus A. Consequently, the Rear Outs control effectively swaps
the left/right outputs in these programs.
