Product Description
The Wolff Audio FREQ is a sweepable 4 band proportional Q parametric EQ in 500 series format, created for engineers who need surgical precision and musical tone shaping in a single module. Designed by legendary console designer Paul Wolff, it delivers everything from broad, flattering curves to ultra-tight notches, making it equally at home on critical mix duties, problem-solving tasks and tone sculpting on the way in.
At its core, the FREQ combines a classic proportional Q topology with modern refinements, extending its range down to 1/3 octave accuracy. As you boost or cut, the Q automatically tightens, letting you carve out problem frequencies without wrecking the surrounding tone, or open things up for smooth, natural shaping when you work more gently. The result is an EQ that feels intuitive, sounds musical and responds exactly as your ears expect.
With four fully sweepable bands, the FREQ gives you precise control across the spectrum, whether you are sweetening a vocal, taming harsh cymbals or pulling out room resonances on a live rig. Its accuracy and consistency make it a trusted tool for repeatable results, while its inherently musical behaviour encourages bold, creative moves without the usual fear of phasey or unnatural artefacts.
Built specifically for demanding professional environments, the FREQ slots straight into your existing 500 series ecosystem and is engineered for long term reliability. It distils over four decades of EQ design experience into a compact, powerful module that can handle everyday corrective work and high end tone shaping with equal authority.
Designed by Paul Wolff
With more than 40 years of EQ innovation behind him, Paul Wolff has poured his design heritage into the FREQ. That pedigree translates into an EQ that behaves exactly how seasoned engineers expect, with familiar, musical responses and a refined sound that flatters sources rather than fighting them.
Advanced Proportional Q Topology
The FREQ uses a proportional Q design where the bandwidth starts wide and narrows as you apply more boost or cut. This gives you gentle, natural curves for subtle shaping and progressively tighter control as you dig in, so you can fix issues or emphasise character without introducing harshness.
Extended 1/3 Octave Precision
By extending proportional Q behaviour down to 1/3 octave, the FREQ moves beyond classic designs to offer genuinely tight notching alongside broad tone shaping. That means you can remove specific resonances or feedback frequencies with confidence, while still using the same unit for wide, musical boosts and cuts.
Flexible 4 Band Control
Four fully sweepable bands give you the freedom to work anywhere in the frequency spectrum. From subtle tonal balance tweaks to more assertive sculpting, the FREQ adapts to whatever the session demands, making it a versatile choice for tracking, mixing and live sound.
Features
- Sweepable 4 Band Parametric EQ - Four fully sweepable bands provide precise control across the frequency spectrum, allowing you to target problem areas or enhance key tonal regions on any source.
- Proportional Q for Musical Response - The bandwidth automatically narrows as you increase boost or cut, delivering smooth, natural curves for subtle work and tighter, more focused action when you need to be assertive.
- Extended 1/3 Octave Capability - Enhanced proportional Q behaviour down to 1/3 octave enables both tight notching for problem solving and broad, flattering tone shaping within a single module.
- Professional 500 Series Integration - Designed specifically for the 500 series format, the FREQ drops into compatible racks to offer premium EQ performance with a compact footprint and streamlined workflow.
