The EMT 250 Electronic Reverberation Unit is a real time audio signal processor, exhibiting high memory capacity and extensive mathematical possibilities. The 250 was introduced in 1976, and it's still regarded as one of the best-sounding reverb units ever made, the EMT 250 was the first digital reverberator to operate through a purely electronic system.
Although only around 250 hardware units were ever built, the EMT 250 continues to leave an immeasurable mark on record-making history appearing on countless records, including Prince & The Revolution’s Purple Rain, Elvis Costello’s Spike, and modern classics like The Red Hot Chili Pepper’s Stadium Arcadium.
It provides a variety of signal processing functions, namely:
High quality reverberation with adjustable decay time and frequency response, as well as determination of the first reflection delay for mono, stereo and quadraphonic signals.
Pure delay of an audio signal by as much as 375 ms available at four separate outputs, each with individually selectable delay time.
"Chorus" with independent pitch variation at four fixed delay taps.
Echo with repetition time adjustable between 5 and 315ms.
Special effect reverberation (SPACE REVERB) with approximately 10s decay time.
