You are about to begin using the most advanced digital
effects system available—the Lexicon 480L. The 480L
is engineered for the all-digital production environ-
ment. Digital audio places strict requirements on every
link in the signal chain, and the 480L meets those
requirements. With its unique 18 bit A/D and D/A
converters, the 480L produces a dynamic range of 98
dB in the wet signal path. It is probably the only effects
system available that doesn't raise the noise floor of a
digital master. And the PCM 1610/1630 compatible
digital I/O interface lets you add true stereo ambience
and effects without leaving the digital domain.
The 480L doesn't just sound better—sheer computa-
tional power allows it to perform multiple audio tasks at
the same time. And what tasks! In the current glut of
throwaway digital devices with ever-cheaper versions
of the same sounds, the 480L offers remarkable new
effects and reverb sounds.
Its innovative reverb algorithms reflect a more accurate
and natural model of the acoustic and psychoacoustic
phenomena of reverb and ambience. Put the 480L up
against any other reverberator—you'll be amazed at
the difference.

Introduction
Introduction
Reverb is only part of the story. The 480L produces
astonishing effects you haven't even begun to dream
about yet. And its sampling programs offer a variety of
useful and unique features.
The present software is powerful and comprehensive,
a dramatic step forward in digital signal processing
technology. Yet it hasn't explored the limit of the 480L's
architecture, which is itself configured for future hard-
ware expansion.
If you are familiar with the venerable 224XL, you'll feel
right at home with the LARC used to control the 480L.
However, there are enough differences in the way the
two units operate that we strongly suggest that you
read this manual as soon as possible. In it, you'll
discover that the 480L's two high speed processors
can operate in a variety of configurations. Samples can
be processed with reverb or effects, all in the digital
domain. Two 480Ls can be connected through their
digital I/O ports for even wider creative horizons. The
480L can even be connected to a 224XL and both units
operated from a single LARC. And that's just the
beginning of what you'll discover--when you read this
manual!
