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
