ACQUA - Erin

Erin represents the state-of-the-art of plugin suites dedicated to mastering. This bundle, consisting of three different studio processors, embodies the luxury mastering equipment as manufactured by one of the most prestigious and appreciated designers in the world, who has been known since the early '70s for his innovative approach in the field of tube-based systems for the high-end, hi-fi market.  Erin includes three different plugins: a 5-band stereo tube equalizer, a stereo tube compressor/limiter and a mid-range tube equalizer.

Erin is our first plug-in to introduce a new technology called ULTRAGAIN™ matching, which consists of an extremely accurate mapping of all gain values in all frequency bands, providing even the most demanding mastering engineer with a perfect resolution, consistency and response. 

The Erin suite consists of:

  • Erin Stereo Tube Equaliser (ERIN EQ ST)
  • Erin Passive Tube Mid-Range Equalizer (ERIN EQ MID)
  • Erin Stereo Tube Compressor/Limiter (ERIN COMP ST)

Each plug-in included in the Erin suite comes in a “Standard” version and an alternative “ZL*” version which operates at *zero latency and is thus suitable for use when tracking, at the cost of extra processing resources. For further details consult the Erin user's manual in the Overview section.

Erin Stereo Tube EQ

The Erin EQ ST is a faithful emulation of an 'esoteric' 5-band stereo parametric equalizer mainly used in mastering facilities. Its utterly prohibitive cost makes it one of the most revered equalizers out there for musically shaping tracks of any genre. We sourced an immaculate unit and carefully sampled it to give you the same creative firepower than only high-end mastering rooms had previously access to.
Both channels of the EQ feature five bands, hi-shelf and low-shelf filters with gain and fixed Q controls. It is also equipped with three boost/cut filters with adjustable center frequency. The preamp and each band can be bypassed at any time using the dedicated button controls.

Erin EQ ST features our new ULTRAGAIN™ matching technology, ensuring extremely accurate gain mapping on all bands and providing even the most demanding mastering engineers with perfect resolution, consistency, and response, all of this while retaining the original behavior and character of the hardware.

Erin Mid EQ

ERIN EQ MID is designed for use on the mid-range, focusing on frequencies from 200Hz to 5kHz. It is a faithful emulation of an extremely intuitive tube unit made in the UK and reminiscent of Pultec-style tube designs.

It features a limited number of selectable frequencies, placed closer to each other compared to other EQ designs, to give you more precise control over this critical part of the spectrum. Finally, a colorful preamp stage and dedicated Mid/Side, Left/Right controls make it a truly versatile processor for more specialized uses. It is therefore a very useful plug-in for all those sources who live in the midrange of a mix like violins, guitars, and vocals.

Erin Comp

Erin Comp is a stereo tube compressor/limiter derived from an esoteric mono unit manufactured in the UK and designed to limit or compress the signal with the minimum of interference below the threshold. It is very simple to operate and features standard attack and release times. A deeply optimized behavior around the 'knee' of the attack/decay envelope and a euphonically transparent dynamic action, makes this compressor a top choice for mixers, mastering wizards, and extremely demanding artists. It is not by chance that legendary Pink Floyd frontman and guitarist extraordinaire David Gilmour owns two of these luxury processors in his unique Astoria recording studio.
