High Performance Discrete Mastering EQ

This module is based on what is considered to be the “golden reference”, the absolute standard in mastering equalizers. This piece of hardware was the brainchild of two of the most ingenious minds in music recording technology, true pioneers (whose ideas were key to many other designs) who joined forces to create what was the first parametric EQ ever invented. The design quickly became the basis for most of the following parametric EQs from manufacturers the world over.
On top of the fully parametric   totally independent bands with almost no interaction (something that was not available until this circuit topology invention), its success derived from its no compromise quality level, based on discrete high-performance custom op-amps   totally transformer-less signal path which made for a transparent   pristine audio quality: this level of sonic excellence, superior transient response, almost non measurable non-linearities   extremely low distortion together with some perceivable "magic" in the circuit design makes it practically ubiquitous in mastering engineers` set of tools, from its origin to present days. The latest   advanced techniques used in the DSP design of this module allowed the perfect rendition of this major league audio quality in the digital DAW format, a level of a sonic sameness that simply wasn`t possible before. The instantaneously noticeable result is that the EQ has a pleasing sound of its own, its high transparency notwithstanding, which is far over the standard "digital" EQ called to perform the same tasks.
On top of this, the analog nature of the hardware is empowered by some digital-world handy features like total recall, full automation,   switchable gain ranges, originally available as three different hardware versions,   now included in a single model.
This last feature is particularly powerful as it allows to use the best resolution of each band`s gain range with extreme precision.
