    Lexicon 480L Owner's Manual Levels in the Digital Domain Analog signals, by nature, have an infinite range of level. During conversion to digital, levels are quantized to absolute values, and expressed as a number of bits. The 480L provides 18-bit resolution in both the analog and digital paths.

    Banks 1-4: the Reverb Programs In this chapter we'll discuss the original Reverberation and Plate programs created for the 480L. Two different algorithms are used to create these programs. The primary difference between the two is the density of the reverberation. The algorithm with greater density is used primarily for Room and Plate programs.
