Much of a  high–end studio's equipment budget in the 1980s would have been spent on high–quality algorithmic reverberators and delays — pictured here are an AMS DMX 15-80 S delay unit (middle), the AMS RMX 16 reverb (bottom) and, just making it into the 80s, the Lexicon PCM70 reverb (top). But even high–end studios would try to make the most of their investments by using these as send effects that could be applied to many tracks at once.
