FREQ is a Sweepable 4 Band, Proportional Q Parametric EQ packaged for 500 series. It is very flexible, extremely accurate and will deliver exceptional audio performance for every project type and size.

Designed by Paul Wolff, a prolific engineer with four decades of EQ design experience and given the FREQ name by early adopter Terry Lewis, this product has serious audio heritage.

The FREQ possesses the desirable features of classic Proportional Q EQs with characteristic wide Q that narrows as you boost / cut. Paul has taken it a step further. Rather than stopping at one octave he has added 1/3 octave capability. With it you can notch tightly with the same EQ that you can use for gradual wide boosts.
