Sony DRE-2000
Fifteen thousand dollars of 1981 digital reverb that engineers kept reaching for long after the spec sheet went stale.
Overview
The DRE-2000 is a digital reverberator. It is not a synthesizer, despite how it's filed here. It comes out of Sony's early-1980s push into professional digital audio. The company's PCM-1610 and PCM-3324 processors went after the recording chain. The DRE-2000 went after the effect: a rack-mount main unit driven by a hand-held 10-key remote, built around a microcomputer, and priced at fifteen thousand dollars when Sony introduced it at the 67th Audio Engineering Society Convention. That is not a typo, and it is not a price inflated by inflation math. The figure appears in Sony's own introduction copy and is repeated in period trade coverage. Mix (May 1983, p.95) confirms the $15,000 figure in a roundup of digital reverb options.
The money bought a machine that could talk to both worlds. The DRE-2000 has provisions for analog and digital system connections. Onboard A/D and D/A converters let it sit in a conventional analog console's effects loop or interface directly with a digital chain. Sony's introduction materials called this "unprecedented flexibility." That's marketing language, but the capability was real and unusual for 1981. The unit processes 16-bit quantized digital signals, and Sony's copy claims the conversion path doesn't degrade the quality of the original signal. That's a claim, not a measurement.
The architecture is where it gets odd. The DRE-2000 runs four modes, two reverb and two delay, with a reverb time range of 0 to 9.9 seconds and delay times from 9 to 999 milliseconds. Frequency response is specified as flat from 10 to 15,000 Hz, adjustable with variable low-cut and high-cut filters. The reverb modes expose pre-delay time, level, and the delay time of both early reflections and sub-reverb, plus the outgoing signal's frequency response. The echo modes give you feedback factor, delay interval, and output response. The delay modes strip it down to delay time and output response. Mix (October 1981, p.21) noted that the unit displays all selected parameters, so you can read the reverb you're running and recall it.
Recall is the headline feature. Sony built in a non-volatile user memory holding up to ten programmed combinations of parameters, with factory presets for each mode on top. Non-volatile means an accidental power failure or a yanked cable doesn't wipe your programs. Power the unit back up and you're either in a factory preset or straight back into your stored work. You can change any single running parameter instantaneously or step program-to-program while operating. Modern Recording (March 1981, p.25) flagged the ten-program memory and hand-held control scheme as the defining features of the announcement. Factory reverb programs covered spring, plate, and typical concert hall, plus a fourth program Sony described as unique; Mix (May 1983, p.95) lists those same categories. Period coverage also claims the DRE-2000's dynamic range and frequency response substantially improved on mechanical reverberation. Again, that's a period claim, not an independent bench result.
Physically it's a heavy rack unit: 5-3/16" x 16-3/4" x 8-1/6", 28.8 pounds including the hand-held control. The remote runs on a 10-metre cable, extendable to 100 metres with an optional adapter. Sony evidently expected the box to live in a machine room while the engineer sat at the console.
The DRE-2000's reputation was built in the studio rather than in the review pages. It shows up in the gear lists of major rooms. Kajem Recording Studios outside Philadelphia took delivery of one and rented it out alongside studio work. It also turns up in session interviews as a first-call snare reverb. Ed Thacker, engineering the Sugarcubes, named the DRE-2000 his favorite for snare drum on that record. Dan Levitin called it one of his favorites for drums generally. It also appears in the credits for Bob Dylan's Shot of Love, used across all cuts for echo and reverb to give a live feel to a controlled studio acoustic.
Here is what this page does and does not know. The DRE-2000 is documented as a 1981 introduction with a $15,000 price, and it was still listed at that price in 1983 trade coverage. Production end date is not documented here. No independent laboratory measurements of the reverb algorithms, noise floor, or converter performance are available in the sources consulted. The frequency response, dynamic range, and 16-bit figures all trace back to Sony's own materials, so treat every spec as manufacturer-stated.
