03In depth

Sound and Character of the Custom Series EQ

Each band of the Custom Series EQ is modeled on a different classic analog equalizer, and each has its own boost and cut design. Because the plugin is not bound by analog circuit limits, bands can behave in ways the original hardware could not.

Slate Digital describes the result as an EQ that can add air to dull tracks, reduce harshness in vocals and add low-end body without sounding boomy. The analog-modeled output section is intended to add musical harmonics and a natural tone.

The developer positions it as a hybrid design that still aims for transparent, natural-sounding results.

Custom Series Lift and Workflow Controls

The Custom Series Lift section is a boost-only parallel filter. It is designed to add life and weight to a track without replacing the main EQ bands.

High Lift opens the top end, and its Present and Silky buttons change how forward the high frequencies sound while keeping them smooth. Low Lift adds bass energy, and its Big and Punchy buttons shape the transient and low-end character in two different ways. Slate Digital suggests trying both options to see which suits the track.
