Passeq is a passive equalizer plugin designed to deliver precise control over your audio's frequency spectrum. It offers three distinct frequency bands for both boosting and cutting, with separate frequency options for each, resulting in 72 selectable frequencies per channel. This extensive range allows for highly detailed and sophisticated equalization curves tailored to your specific mixing needs.

The plugin faithfully recreates the characteristic sound of the original hardware, capturing the subtle interactions between passive filters. It includes an emulation of input and output transformers to enhance tonal richness and warmth. Passeq also features a switchable mid/side mode, enabling independent processing of the central and side elements of your stereo signal for more creative control over your mix.

Users can choose between two graphical interfaces: a dual-channel view for comprehensive stereo editing and a compact single-channel view that conserves screen space. This flexibility makes Passeq suitable for a wide range of production workflows, from detailed mastering sessions to dynamic mixing environments, all while maintaining the unique character of the original passive EQ design.
