Manley Massive Passive Stereo EQ Mastering Version has a simple, passive design – not a standard parametric design – for more natural, organic shaping. It also gives you mechanically detented knobs for both Gain and Bandwidth controls, so you can easily repeat your settings. On the Massive Passive Mastering Version, both the Gain and Bandwidth controls intentionally interact, and the bands interact, as well – this creates an incredible-sounding result without sounding “colored” or “processed.” Also, both higher and lower than the normal version, the Massive Passive Mastering Version’s filters are tailored to mastering purposes.
