Based on the monumental mastering grade EQ
The original MEP 250 EQs were among the first parametric EQs available. Legendary for their flexibility and sound quality, they are still considered among the best EQs ever made, and fiercely sought after even today by the best studios in the world. 

A painstaking emulation of an ideal analog device
Just like the AMEK EQ 200, the AMEK EQ 250 plugin is inspired by the sound of Dirk Ulrich’s own analog devices, and one of his personal favorites: in this case the Sontec MEP 250ex. It’s a model that has been heard on countless hit records, and renowned for its sweet sounding top end and tight, focused bottom.

High end analog audio history in your DAW
The MEP 250ex is a direct descendant of the original parametric EQs created by the pioneers of this technology, made without inductors or switches for an uncompromising signal path. Closely related to the MES 430B EQs found in high end mastering studios, the MEP 250 style of EQ features fully variable controls to provide the freedom and control mixing engineers demand.

Made even more powerful with plugin-only features
Brainworx’ familiar “Extra Unit” adds features to this “holy grail” EQ that cannot be found on the original analog units. This retractable module includes Tolerance Modeling Technology, M/S Processing, Mono-Maker, Stereo Width, THD, Auto Listen for all five bands and more, providing everything you need in the modern digital domain.

    The 250 does everything. The tight low-end and sparkling clean highs are a magical broad stroke mastering paint brush I will be using daily on my masters.
