Product Highlights

The Wolff Audio FREQ boasts a uniquely sophisticated design that redefines tone-shaping versatility for the modern studio, allowing you to freely combine broad, flattering curves for subtle tone shaping and deep hi-Q notches for surgical sculpting. Traditionally, proportional-Q curves are determined by the amount of boost or cut (i.e., the larger the boost/cut, the narrower the Q). Venerable design wizard Paul Wolff’s fresh take on the sweepable 4-band proportional-Q parametric equalizer, FREQ employs a more useful implementation, giving you control over the Q across all four bands, regardless of the amount of boost or attenuation. Featuring impeccable build quality and Cinemag transformer-balanced output that lends gravitas to its sound, the Wolff Audio FREQ deserves a space in every well-stocked 500 Series rack.

EQ flexibility — redefined

FREQ’s high and low bands offer up to 15dB of boost or cut at 2kHz–20kHz and 75Hz–700Hz, respectively. Both bands feature a Wide mode button which, when pressed, changes the default 1/3-octave shelving to fixed-Q 2.5-octave bell curves. The high-mid and low-mid bands, spanning 350Hz–10kHz and 25Hz–2.2kHz, respectively, also offer ±15dB of boost/cut, but they operate a bit differently with respect to Q. Here, the default is proportional-Q, which can be switched to a fixed 1/3-octave hi Q with a press of the 1/3 notch button available on both midrange sections. As the two midrange bands overlap each other, as well as the HF and LF bands, you can employ an age-old studio trick that involves broad boosts combined with narrow cuts. On kick drum, try a broad boost at, say, 60Hz and a narrow cut at 400Hz. Adding bottom-end weight while attenuating frequencies that crowd the lower midrange allows the kick drum to punch through the track without obscuring other elements in your mix. While your mileage may vary as to exact frequencies, the Wolff Audio FREQ gives you complete freedom to sweep around and zero in on your target sound.
