SPL Passeq

The Most Powerful Passive EQ - EVER!

Overview

The most powerful passive EQ ever! The original hardware Passeq was the first passive EQ to provide three separate frequency ranges for both boost and cut. The Pultec EQ, the famous passive EQ from the 1950’s and 60’s featured just two frequency bands, and had very limited switchable frequencies. SPL’s Passeq has 12 switchable frequencies per band, totaling 36 boost and 36 cut frequencies! Boost and cut frequencies are NOT identical, thus the resultant 72 frequencies per channel offer an enormous choice for the most elaborate EQ curves. The Passeq offers, for the first time, passive filter control possibilities with an unheard of abundance of filter choices.

The fantastic quality of SPL’s Analog Code programming faithfully reproduces the unique sound characteristics of the original hardware Passeq. All the complex interactions between each single filter are faithfully preserved in every detail. One of the unique qualities of passive EQ designs is that the audio signal reacts to the multiple bands as one big filter. Whenever a setting changes, the entire interaction between EQ bands occurs. This provides the unique characteristics and very special sound of these EQs — something that simply does not happen with active EQ designs.

The combination of all this filtering power, mastering grade sonic quality, and advanced M/S processing (a software-exclusive feature!) make the SPL Passeq THE plugin to have for mix busses and mastering.
