1. Introduction

Pultec’s simple and effective filter features two knobs: one each for passive low-cut and high-cut filters at carefully selected frequency intervals. With 10 frequency selections available per band, it is the perfect tool for creating space in your mix by eliminating unneeded frequencies at the extremes of the audio spectrum — while ensuring a musical analog tone.
Even if you don’t intend to use the cutoff filters, try inserting the VEQ-HLF in your processing chain to obtain its peculiar and highly sought-after sound coloration.

5. Glossary

5.1 Shelving EQ
A shelf type EQ is the boost or cut of all frequencies above or below the cutoff frequency. It is most commonly found on the top and bottom bands of a parametric EQ.
5.2 Bell Curve
All equalizers with peaking filters use a bell curve which makes the EQ smoothly process a range of frequencies. With the bell curve, the center frequency occurs at the top of the bell curve and is the one most affected by equalization.
5.3 Low-cut Filter
Also known as high-pass filter. There are two types of pass filters in equalization. A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. Thus, it is commonly used for cutting low frequencies. A low-pass filter (LPF) works the opposite – it attenuates content above a cutoff frequency, letting lower frequencies pass through the filter.
