The 50th anniversary Model 2830*Au Omnipressor® is a professional-quality dynamic modifier, combining the functions of an analog compressor, expander, noise gate, and limiter in one convenient package. Its dynamic reversal feature makes high-level input signals lower than corresponding low-level inputs. Musically, this reverses the attack-decay envelope of plucked strings, drums, and similar instruments and gives the effect of “talking backward” when applied to a voice signal.
The new 50th anniversary model incorporates professional Lundahl transformers on both input and output, a switchable active-balanced side-chain, stereo and master linking capability and a mix control for parallel compression applications. Balanced/unbalanced XLR and TRS options are provided throughout.
Introduced 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.
Originally invented by Eventide’s founder, Richard Factor (and later redesigned for production by Jon Paul), the Omnipresssor made a host of 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 today we take for granted like ‘look ahead’ processing. One of the first customers was a young Brian May, lead guitarist of Queen. With the Omnipressor in his rig, his sound was never the same.
