Thus, the Holy Grail of graphic equalizers is a device with a response that truly matches the slider settings. For years, this seemingly unobtainable goal resulted in products based on the fine art of compromise … until now … until the DEQ 60. It’s not Constant – not Proportional – It’s Perfect! Digital Signal Processing (DSP) allows filter technology not possible with analog designs. Rane coined the term Perfect-Q™ to describe the results (U.S. & international patents filed). The DEQ 60 is the world's first true graphic equalizer (i.e., one providing real mechanical front panel slide controls) whose output response precisely matches its front panel settings. Perfect-Q features virtually no band interaction and extremely low ripple between adjacent bands. To keep things flexible, fear not proportional-Q lovers, each channel of the DEQ 60 is selectable between Perfect-Q or Proportional-Q response. For all the details, read the RaneNote “Perfect-Q, the Next Step in Graphic EQ Design” available at the Rane website. The DEQ 60 is available in two versions: The DEQ 60 with 25 mm sliders, and the DEQ 60L with 45 mm sliders. The DEQ 60L also features a switchable Cut-Only mode. The DEQ 60 Graphic Equalizer provides the most complete set of pure EQ functions ever offered in an analog controlled equalizer.
