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 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 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 60L is selectable between Perfect-Q or Proportional-Q response.
We know you know how to use a realtime analyzer, but using PERFECT-Q mode will make that a lot easier. Since there is no interaction between filters, the multiple adjustments through all the bands just to get the analyzer to read flat is a thing of the past. One pass should do the trick. Then use the TONE controls or CUT FILTERS for general sweetening. We know your sound is important and your time is valuable.
If you want to compare the sound of your old (non-Rane) EQ to this one, and you are used to the way the slider bands interact, then use PROPORTIONAL-Q mode. It's your choice with the front panel switch.
LOW, MID, and HIGH TONE controls provide independent, Accelerated-slope™, 3-band Tone controls allow easy, intuitive adjustment of tone response without the hassle of adjusting 30 bands. The Tone controls use 12 dB per octave Linkwitz-Riley filters. As with the EQ sliders, center detent provides a guaranteed flat response.
Additionally, the LOW CUT and HIGH CUT FILTERS remove the unheard and unwanted extremeties.
The LOW CUT FILTER is adjustable over four octaves with a frequency range of 15 Hz to 240 Hz.
The HIGH CUT FILTER is adjustable over two octaves from 5 kHz to 20 kHz.

DEQ 60L Data Sheet DEQ 60L Manual Safety and Compliance DEQ 60L line art without sliders for record-keeping DEQ 60 Review in EQ Magazine by Craig Anderton, May 2003 DEQ 60 Review in Live Sound Magazine, July 2003Note: The DEQ 60 model has been discontinued. Though it shares most DEQ 60L features, It had shorter faders and did not have the Cut-Only mode switch.
Each unit is shipped with a booklet containing the Manual with Safety and Compliance information, the Data Sheet, the RaneNote "Sound System Interconnection," Declaration of Conformity, and Rane's 2+ Year Warranty information.
Can I use the XLR and 1/4" and Euro outputs at the same time?
Yes. Both sets of output connections may be used simultaneously. However only one input may be used at a time. If you combine a unbalanced 1/4" with a balanced XLR you could create a ground loop problem. See "Sound System Interconnection" below.
