More than a Compressor
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.
Features
- 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

Reviews
Aggressive and shouty.
Omnipressor is a compressor and expander/gate dynamics plug-in that goes about the business of compression in a very aggressive and shouty way. If you are looking for a subtle transparent compression then look somewhere else, if you want a compressor with bags of pump, depth and character then look no further.
