Step into a new era of tonal precision with the Wolff Audio FREQ 500 Series Parametric EQ with Proportional Q. Designed for the discerning audio engineer, this EQ module marries innovative proportional-Q design with the charm of vintage analog warmth. Tailored for versatility, the FREQ allows for intricate tone sculpting, from broad, smooth curves to precise, surgical cuts, offering unmatched flexibility in shaping your sound.

The FREQ's design allows seamless control over the Q factor across its four bands, independent of boost or attenuation levels. This unique approach, along with the Cinemag transformer-balanced output, ensures that each note you shape is delivered with pristine clarity and added depth. Whether you're seeking to add subtle enhancements or need to carve out specific frequencies in the mix, this EQ is your go-to tool.

Perfect for both studio veterans and budding producers, the FREQ's high and low bands offer up to 15dB of boost or cut, while the mid bands provide proportional-Q curves that can be switched to fixed-Q with ease. The overlapping frequency ranges encourage creative techniques like broad boosts combined with narrow cuts, allowing instruments like kick drums to cut through the mix with precision.
