Eventide Audio has announced the golden anniversary Omnipressor Model 2830*Au, a faithful recreation of the iconic compressor that introduced the concept of dynamics processing for special effects.

Originally unveiled in the early 1970s, the Omnipressor was the first dynamics effects processor of any kind, suddenly making possible a new, wide range of dynamics effects unlike anything that had come before it.

Fast forward to today, the original hand-drawn schematics were in the Eventide archives, and the new model is a faithful replica designed with the same circuitry and the same sound as the original 2830. Additionally, the new *Au model features the ability to link multiple units and is fitted with input and output audio transformers, which were a costly option on the original. Other improvements include a universal power supply and a backlit meter. More convenient TRS/XLR connectors replace the original terminal strip.

Omnipressor Model 2830*Au features

  • Dynamics Processing: Capable of creating otherworldly sounds.
  • Dynamic Reversal: The first of its kind, soft signals come out loud and loud signals come out quiet, simulating tape reversal, a near unique attribute of this versatile compressor.
  • Function Control: Sets a ratio over a continuous range allowing extreme expansion, to infinite compression, and is even able to push further into dynamic reversal.
  • Variable Control of attack and release time, and maximum gain and maximum attenuation..
  • Gating: Amplitudes of signals that fall below a set threshold are ‘squooshed’.
  • Expansion: Widen a signal’s dynamic range, louder gets louder, softer gets softer.
  • Compression offers variable control of compression ratio.
  • Infinite Compression: If you want everything to come out at the same level, this is the feature for you.
  • Limiting: A fast, versatile limiter, useful for maintaining a loud sound.
  • Intuitive Interface: Clean and easy to operate.

Priced $1,999 USD, the 50th Anniversary Reissue is now available to pre-order. Shipping will start in January 2024.
