Classic Shelving Character With Dynamic Mid Bands
The low and high shelving filters model a classic passive EQ unit and include separate boost and attenuation controls. Setting both boost and attenuation above 0 dB on a shelf reproduces the 'Pultec' style of simultaneous boost and cut that the developer highlights for low-end shaping.
The two parametric mid bands work differently. Each has gain, Q and dynamic attenuation controls, and a compression algorithm makes these bands react to the signal rather than applying a fixed cut. This is the main point of difference from a static EQ.
