DEQ 60L
GRAPHIC EQUALIZER
General Description
When the term “graphic equalizer” was rst 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.
us, 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
ne art of compromise … until the DEQ 60L.
It’s not Constant—not Proportional—It’s Perfect! Digital
Signal Processing (DSP) allows lter technology not possible with
analog designs. Rane coined the term Perfect-Q™ to describe the
results (U.S. patent 7,266,205). e DEQ 60L is the rst 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
exible, 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 the Rane website.
DATA SHEET
e DEQ 60L features 45 mm sliders, a switchable Cut-Only
mode, additional Cut lters, and additional 3-band Tone con-
trols. e DEQ 60L provides the most complete set of pure EQ
functions ever oered in an analog controlled equalizer.
