1. Introduction

Having imparted its sound signature on generations of artists and hit recordings for more than 50 years, the VEQ-4K series are based on a rock-solid analog design — now brought to life in Antelope’s FPGA FX modules.
The Antelope VEQ-4K series is complete with four different-colored hardware-original revisions, each delivering its own unique sound shaping characteristics. The revisions are Black, Brown, Pink, and Orange. This manual will deal with all four versions.

2. VEQ-4K Black

Likely the most popular version of the EQ module, this unit was designed following the recommendations of many of the world’s top engineers. The ‘original black’ has a louder EQ with +-18dB cut/boost and a steeper High Pass cut off slope (18db).

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.
