The Lexicon PCM60 is a stero reverberator from the mid-eighties. While there certainly have been advances in DSP, AD/DA converters, and overall processor design, the PCM60 still can hold its own. The simple user interface is unmatched in today's market (although dbx tried to copy it a few years back) and requires little effort to dial in the right sound. The PCM60 doesn't have too many parameters, so there's really no need to go to great lengths decribing it. There are input, mix, and output controls along with a five segment input meter. A bypass button is provided to take the PCM60 out of a mix. Two reverb types are provided: room and plate. For each type there are four settings for size, and four settings for decay. High and low contours can be applied to the reverb, although they are on/off, not continously variable. The reverbs are lush and work great on drums. If you're looking for realism look elsewhere. If you want fat, pick up a PCM60.
