The Yamaha REV500 delivers extraordinary reverb depth and resolution for ambiance that can only be described as “alive”.
The Dynacord DRP 20 Digital Reverb Processor is without a doubt the most popular digital reverb in the Dynacord range from the 80s period.

We have very little information on the Dynacord DRP 20 other than the information below which was translated from a German document. If you have anything in English on this processor please let us know.
The Dynacord DRP 20 is really two channels constructed. with stereophonic inputs and stereophonic outputs. They allow him as a true stereo device (stereo in stereo), as a transformer balanced two-channel device (2x mono to mono) or as a normal Stereo device to use (mono in stereo).
The digital signal processing is performed in a new, developed and manufactured by NEC Dynacord signal processor with 32 bit floating point technology, which achieves a dynamic range of 770 dB internally.
Thus consuming internal operations are performed quickly and accurately even imperceptibly. The 16 bit A/D and D/A conversion corresponds to the current CD standard and allows the excellent studio moderate sound quality.
There are 100 factory presets and 128 additional free user memories available. You can complete the data users benches along with their Midi settings stored on compact cassette or the like, or warden loaded into the Dynacord DRP 20. The Dynacord DRP 20 has a very comfortable Midi department that the advanced user Midi offers completely new possibilities themselves.
For example, the external control of all parameters in real time (sequencer, keyboard) or simultaneous control of multiple parameters with a control function, or creating 5 different midi mapping tables, or more.
This subroutine allows individual, for the user freely definable presets (eg parameter values 0 “100 or in dB), and a variety of tests, including White Noise – and Pink Noise generation and more.

I had a white-face DRP-20 for many years, and even though I really loved its huge-sounding reverb ambiences (and I mean *huge*), I decided to part with it because its noise level was really annoying. There was a constant hiss, running reverb tails through an RSP Hush 2000 would help with shorter reverbs, long reverb tails would sooner or later start to flutter.
The build quality is quite good although I encountered problems with sticky keys and erratic enconcers — I am sure the Dynacord people would refurbish one for you if you are prepared to send it to them. Programming is easy and straightforward, combining various different types of delays and reverbs makes for some really rich sonic palette. Now if there weren’t that noise problem… the Cathedral algorithm run through a Dimension D was simply stunning, and I confess I really miss that.
