From the Manufacturer
Congratulations on your purchase of an Ashly GQX series graphic equalizer. The GQX series equalizers are a second generation design including many refinements on our original GQ models. Lower noise and distortion, greater accuracy, and additional output options are the result. We continue using “Q” enhanced Wein bridge filters and interleaved summing for constant “Q”, low ripple, and minimum filter interaction. A servo-balanced output stage simulates a true transformer output to allow interfacing with virtually any type of load.
