UAD Powered Plug-Ins Manual - 295 - Chapter 27: Lexicon 224
Operational Overview
Graphical User
Interface
The original Lexicon 224 consists of two hardware elements. The “main-
frame” rack-mountable 4U chassis contains the power supply, circuitry, and
audio input/output connectors. The remote control unit has a display, buttons,
and sliders which control the 224 parameters and functionality. Some of
these buttons and sliders have dual and even triple functionality, which makes
using certain “buried” functions a tricky procedure.
The UAD Lexicon 224 interface resembles the appearance and functionality
of the original hardware remote control. Operation has been simplified how-
ever by reassigning the buried “shift” functions to the buttons that are no
longer necessary in a plug-in (such as managing saved programs). Additional
parameters are exposed by opening a panel cover.

Programs
The original Lexicon 224 hardware has “programs” that are defined by the
firmware ROM (“Read-Only Memory” chip) installed in the unit. A Lexicon
224 “program” is comprised of a unique DSP algorithm and an initial set of
factory parameter values voiced by Lexicon. In modern terminology, these ini-
tial values would be called a “preset.”
In Lexicon 224 hardware-speak, a program is “called” (loaded) which selects
the DSP algorithm and sets the default “recommended” factory parameter val-
ues. These settings can then be modified with the various controls and saved
in a user “register” for later recall. The plug-in behaves the same way, except
user “registers” are not implemented. Instead, user settings are stored within
the session file or they can be saved as a preset for later recall (like all other
UAD plug-ins).
Lexicon 224 version 4.4 firmware contains nine programs (the maximum
available for the unit), consisting of eight reverb programs and one chorus
program. Descriptions of the various programs can be found on
page 309 .

Algorithms
The active algorithm determines the inherent sonic character of the current
program. Algorithms are changed by selecting a different program; the algo-
rithm cannot be changed within the same program.
Lexicon 224 v4.4 contains seven unique algorithms. All seven algorithms and
the nine factory programs have been authentically modeled in the UAD Lexi-
con 224 plug-in. There are more programs than algorithms because some
programs use the same algorithm. See
“Program Descriptions” on page 309
for details.
