When the term "graphic equalizer" was first coined, the intent was
to provide a device that allowed the user to "draw" the desired
frequency response using slider controls on the unit's front panel.
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-QTM 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. Just to keep things interesting and flexible, fear not proportional-Q lovers, for each channel of the DEQ 60 is selectable between Perfect-Q or proportional-Q response.
