Digitally processed reverberation effects
With the advanced digital technology employed in the Sony DRE 2000, high-quality reverberation effects with a better signal-to-noise ratio, better frequency response and wider dynamic range can be added to incoming signals.

Reverberation not susceptible to external vibration
Unlike conventional mechanical reverberators, the Sony DRE 2000 is unaffected by external vibration or mechanical shock because all operations are performed electronically. Because of this, the Sony DRE 2000 can be installed almost anywhere.

Reverberation parameters easily programmed
The reverberation parameters which determine the reverberation characteristics are easily programmed with the parameter buttons on the supplied remote control unit.

Programs can be memorized
Up to 10 programs can be stored in the non-volatile memory for later recall.

Delay modes
The delay function produces a delay between the sound source and the delivered signal, with delay times of from 1 to 999 milliseconds (for each channel) in mode-1 and delay times of from 1 to 999 milliseconds (channel 1) and from I to 499 milliseconds (channel 2) in mode-2.

Echo modes
Echos can be added to incoming signals in two modes. In mode-1, the same echo pattern is added to both channels and in mode-2, different echo patterns are added to each channel.

Pre-prograrned reverberation, delay and echo modes
Four modes of reverberation, two modes of delay and two modes of echo have been pre-programmed in the unit.

Compact and lightweight
The Sony DRE 2000 is more compact and lightweight than conventional mechanical reverberation units.

sony dre 2000 mystery

Wazup fellas, What's actually all the fuzz about sony's 80s dre 2000 reverb unit? Isn't a contemporary digital plugin reverb much better than those old rack units? Mike

...figures. I know Sean sent him the AES paper. The algorithm described in the paper isn't really related to the DRE 2000 design. I've only run into weird things like that when dumping mask ROMs, usually because the chip enable pin is active high rather than active low (this allows two ICs to use the...
