Informationen:
                                    The Lexicon 480L is the most advanced digital effects system
available. With its unique 18 bit linear 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 computational 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.
Reverb is only part of the story. The 480L produces
astonishing effects you haven't even begun to dream about
yet. And its sampling program offers a variety of useful and
unique features.

The present software is powerful and complex, 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 hardware 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. One 480Lcan serve two
control rooms. Or 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.
