Sweepable 4-band parametric EQ with Proportional Q, 1/3 octave notching, Cinemag transformer, and bypass switch for precise, clean, and flexible audio shaping.
The Wolff Audio FREQ is a highly versatile 4-band parametric equalizer designed for the 500 Series format. Engineered by Paul Wolff, a legendary name in EQ design, and named by Terry Lewis, this unit blends classic Proportional Q EQ characteristics with modern enhancements for surgical precision and tonal shaping. Whether you're making broad tonal adjustments or tight notches, the FREQ delivers exceptional accuracy and flexibility, making it a must-have for any professional audio setup.
Key features include Proportional Q, where wider Q settings are used for subtle adjustments, and narrower Q settings are applied when making deeper cuts. The HIGH and LOW bands offer a WIDE mode, acting as a gentle 3-octave-wide filter instead of a traditional shelving EQ, minimizing unwanted out-of-band clipping. The two MID bands feature a 1/3 Octave lock for precise frequency notching, helping eliminate problem frequencies with surgical precision. A Cinemag nickel and steel blended output transformer ensures transparent signal integrity with minimal coloration. Additional features include a hardwire relay bypass, a green signal indicator, and low distortion (<0.03%) for clean, high-headroom performance. Whether used for subtle tonal shaping or aggressive correction, the FREQ is built to handle it all effortlessly.
