The legendary Omnipressor® returns with a vengeance in its 50th anniversary Model 2830*Au edition, bringing together four essential dynamics processors in one groundbreaking unit. This professional-grade dynamic modifier seamlessly combines analog compression, expansion, noise gating, and limiting capabilities, whilst its unique dynamic reversal feature creates the fascinating effect of making high-level signals quieter than their low-level counterparts. Musicians will find this particularly striking when applied to plucked strings and drums, as it reverses the natural attack-decay envelope, or when used on vocals to create that distinctive "talking backward" sound.
The anniversary model has been significantly enhanced with professional Lundahl transformers on both input and output stages, plus a switchable active-balanced side-chain for maximum flexibility. Stereo and master linking capabilities are included alongside a dedicated mix control specifically designed for parallel compression applications, whilst balanced and unbalanced XLR and TRS connections are provided throughout the unit.
Breaking new ground in the early 1970s, the original Omnipressor was the first dynamics effects processor ever created, opening up an entirely new realm of sonic possibilities that had never existed before. Originally conceived by Eventide founder Richard Factor and later refined for production by Jon Paul, this revolutionary device introduced variable control over all aspects of dynamic modification and pioneered concepts like the side-chain and look-ahead processing that are now industry standard. Among its first adopters was a young Brian May of Queen, whose guitar sound was permanently changed by incorporating the Omnipressor into his rig.
- Switchable External Side-chain — fully integrated version of the original
- Mix/Blend Control — allows for built-in parallel compression
- Configurable Stereo/Master Linking — useful for bus compression and multi-channel dynamics processing
- 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
- Variable Control of 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
