Data Sheet; General Description - Rane DEQ 60L Manual

General Description

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 the DEQ 60L.
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. patent 7,266,205). The DEQ 60L is the 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
60L 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 rane.com.
