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.
