Eventide Omnipressor 2830Au 50th Anniversary Reissue

50th Anniversary ReissueEventide commemorates the 50th anniversary of the legendary Omnipressor by introducing the golden-anniversary Omnipressor Model 2830 Au, a truthful recreation of the iconic compressor that introduced the concept of dynamics processing for special effects.

Omnipressor was the first ever dynamics effects processor, suddenly making a new, wide range of dynamics effects possible, unlike anything that had come before it. Originally invented by Eventide’s founder, Richard Factor (and later redesigned for production by Jon Paul), the Omnipressor hosts a range of dynamic effects possible. It featured variable control of all aspects of dynamic modification. It also introduced the notion of the ‘side chain’ and foretold techniques that are taken for granted today like a ‘look ahead’ of processing.

Eventide now introduce the golden-anniversary Omnipressor Model 2830*Au. The original handdrawn 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.

amazing 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 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 maximum gain and maximum attenuation
• Variable Control of attack and release time

unique effectsIn 1973, Eventide Clockworks introduced the Omnipressor, the first studio product to encourage the use of dynamics for special effects. It joined the Instant Phaser® in studios across the world, with the Instant Flanger® following shortly after. All were used on countless recordings and are now considered truly classic products.

Unlike the Phaser and Flanger, the Omnipressor, with its still-unique dynamic reversal, infinite compression, variable gating and separate “side chain,” was discontinued a few years later. It had become difficult to obtain some exclusive parts and even more difficult to explain it to an industry that was much less sophisticated than it is today.

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 back-lit meter, as well as more convenient TRS/XLR connectors replace the original terminal strip.
