Lexicon 480L Digital Reverb and Effect Processor
The 480L is engineered for the all-digital production environment. 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 98dB 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 1 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.
