The Wolff Audio FREQ is a high-precision stereo equaliser with four fully parametric bands per channel, delivering transparent, mastering-grade tonal shaping with robust build quality and discrete, relay-switched signal paths.

Wolff Audio FREQ 500 Series Equaliser Details

The Wolff Audio FREQ is a precision-designed stereo equaliser that brings mastering-grade performance into any studio environment. Created by Paul Wolff, whose legacy includes decades of pioneering audio designs, the Freq was developed with the goal of delivering the cleanest, most musical equalisation possible without compromise.

The Wolff Audio FREQ offers four fully parametric bands per channel, covering a wide frequency range with broad adjustability. Each band provides sweepable frequency selection, adjustable Q (bandwidth), and boost or cut controls. The equaliser’s sonic character is extremely transparent, allowing engineers to shape tone without imparting unwanted colour or phase distortion. It is capable of making bold tonal shifts or subtle enhancements while preserving the integrity of the original signal.

A high-pass filter is included to remove unwanted low-frequency rumble, and each channel features a true hardware bypass to ensure the most direct signal path when EQ is not required. All controls are fully discrete, and switching is performed using sealed relays to maintain perfect signal integrity and long-term reliability.

The Wolff Audio FREQ’s front panel layout is clean and intuitive, designed for fast, precise operation. Its mechanical design is equally robust, with a heavy-duty steel chassis built to withstand the demands of daily professional use. High-grade components are used throughout to guarantee consistent performance, making the Wolff Audio FREQ a trusted tool for mixing, mastering, and critical listening applications where sonic precision is essential.

The Wolff Audio FREQ represents the culmination of decades of engineering expertise, offering true high-end equalisation in a flexible, reliable, and musical package.
