The Wolff Audio FREQ is a Sweepable 4-Band Proportional Q Parametric EQ for the 500 series, combining precision, flexibility, and advanced engineering to deliver exceptional audio performance for any professional application.

Exceptional Audio Design Heritage

Designed by Paul Wolff, a renowned engineer with over 40 years of experience in EQ innovation, the FREQ embodies decades of expertise and dedication to superior audio quality. The name “FREQ” was coined by its first adopter, Terry Lewis, and this heritage cements its position as a premium product for audio professionals seeking unparalleled control and precision.

Innovative Proportional Q Technology

At the heart of the FREQ is its Proportional Q functionality, a feature highly sought after in classic EQ designs. The Proportional Q design offers a wide Q that narrows dynamically as the user applies boost or cut, allowing for highly musical results. However, Paul Wolff has elevated this feature by extending its capability beyond one octave to include 1/3-octave precision. This enhancement enables tight notching for problem-solving alongside broad, smooth tonal shaping within the same unit.

Flexible and Accurate Performance

The FREQ's four sweepable bands allow precise targeting across the frequency spectrum, making it suitable for fine adjustments and broad tonal changes alike. Its flexibility ensures it adapts seamlessly to diverse tasks, from addressing subtle tonal balance issues to solving challenging audio problems. With its unmatched accuracy, the FREQ delivers consistent and reliable results in both studio and live sound environments.

Built for Professionals

Wolff Audio has designed the FREQ to meet the needs of modern professionals who demand versatility, reliability, and superior sound. Its robust construction and cutting-edge technology ensure long-lasting performance, making it an indispensable tool for audio engineers across all disciplines.

The Wolff Audio FREQ is not just an EQ—it is a groundbreaking evolution of classic design, providing the precision and musicality audio professionals need to elevate their craft.
