QUICK START
We know you know how to use an equalizer. Just read this section for the unique things to be aware of in the DEQ 60.
We know you know how to use a realtime analyzer (Rane makes a great one, the RA 30), but using PERFECT-Q
mode will make that job 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 sliders
interact, then use PROPORTIONAL-Q mode.
The Aand Bswitches are like memories or control assigns. Normal stereo use would set the top row A (Left), and the
bottom row to B (Right). But if you are running in stereo, and both sides use the same EQ curve, you can set both switches
to A. Now the top EQ curve controls both left and right channels. Switching these to Bwill use the bottom EQ curve for
both channels. This is great for switching EQ when a source changes. Just be aware of where these switches are, an
unassigned EQ row will have no audible effect. These switches also affect the CUT FILTERS, TONE CONTROLS, and
LEVELS.
The Channel BYPASS switches have two modes, set by the rear panel switch. When set to FILTERS, the BYPASS
switch only bypasses the EQ, TONE and CUT FILTERS. The LEVEL controls and other switches remain active. When
set to ALL, the BYPASS switches ignore everything including the LEVEL controls.
You have several connector choices on the rear. However, use only ONE type of INPUT on each Channel. These Inputs
do not sum. But you may use any combination of OUTPUTS simultaneously if desired. Polarity convention on the XLR
jacks is pin 2 positive, pin 3 negative and pin 1 shield (chassis ground).

햲Graphic EQ controls: Thirty bands of EQ are provided for each channel. Each EQ slider has a resolution of 256 steps. The
center detent position guarantees a flat response. Slide control travel is 25 mm. Comfortable, easy to read, soft touch knobs
are provided.
햳LOW, MID, and HIGH TONE controls: 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. The Low/Mid crossover point is 300 Hz. The Mid/High crossover point is 4 kHz. As with the EQ sliders,
center detent provides a guaranteed flat response. The range of control is +6 dB to off. Control resolution is 256 steps.
햴LOW CUT and HIGH CUT FILTERS: The LOW Cut Filter is adjustable over four octaves in 64 steps with a frequency
range of 15 Hz to 240 Hz. The HIGH Cut Filter is adjustable over two octaves in 64 steps from 5 kHz to 20 kHz.
햵LEVEL controls serve two purposes, when used with the Meters (햺):
1) Adjust the INPUT signal level to 0 dBu for good headroom and signal to noise.
2) Compensate for changes in signal level due to filter boost/cut settings by adjusting the OUTPUT signal level to 0 dBu.
The operation of the OUTPUT LEVEL control is reversed. Pushing the control up reduces gain. Pushing the control down
increases the gain. This allows the user to easily adjust sensitivity without affecting the output signal level. Simply grasp
both input and output controls and move together. The ranges of both controls is ±12 dB with a resolution of 256 steps.
햶BYPASS switches have two possible modes of operation. If the rear panel switch is set to BYPASS ALL, all filters and
level controls are bypassed. If the rear panel switch is set to BYPASS FILTERS, only the filters are bypassed. Filters
include EQ, TONE and CUT. Automatic relay bypass hardwires Inputs to Outputs in the event of a power failure.
햷A / B switches determine which set of controls is used by the A-Channel or B-Channel. Controls affected by the A / B
switch are EQ, TONE, CUT FILTERS, LEVEL, Q switches and ±12 / ±6 dB switches. Bypass switches are not affected.
햸PERFECT-Q™: What you see is what you get. PROPORTional-Q: Classic smooth response. Most users will prefer this
switch in the PERFECT-Q position. Some users may prefer the PROPORT-Q setting. See Graphic EQ Controls on page
Manual-4.
햹±12 / ±6 dB switch changes the boost cut of the Graphic EQ (햲) for each Channel. Use the ±6 dB unless you really need
±12 dB, the resolution is better.
햺Input and Output Meters are peak responding and indicate the signal level in dBu. Peak-dBu is held and displayed for 1.5
seconds. Attack is instantaneous. Decay is 500 ms for a 20 dB step.
햻When the POWER indicator is on, it indicates that power is turned on. This works with 햵on the Rear Panel (next page).

햲CHANNEL A and B INPUTS: Plug the outputs of the mixer or other source to these Inputs. Choose between the XLR, the
¼" TRS, or the Euroblock Input jack—use only one—they do not sum.
Rane adheres to the international and U.S. standard for balanced pin configurations: Pin 1 is chassis ground (neutral), pin 2
is hot (positive), and pin 3 is signal return (negative).
Avoid the temptation to use unbalanced tip-sleeve ¼" TS plugs, but if you must, keep them short as possible, 10 feet (3
meters) maximum. Long unbalanced cables invite hum, noise and other undesirables. Balanced TRS ¼" are much better at
rejecting noise.
The Euroblocks normally connect the cable shield to the ground terminal. For those installations where the internal shield-
to-chassis connection causes interference, connect each shield directly to the chassis grounding screw located above each
Euroblock connector, keeping the shield wrapped around the audio conductors as much as possible. For optimum Electro-
magnetic Interference (EMI) immunity, connect the shields at both ends of the cable to chassis ground.
See the RaneNote “Sound System Interconnection” for more information on system connections and proper grounding
practices.
햳CHANNEL A and B OUTPUTS: Any Output can be used simultaneously with the others, take your pick. Same wiring as
above...keep cables short, always wire balanced when possible, eat your vegetables, yadda yadda.
햴BYPASS mode switch: See 햶, Front Panel, previous page.
햵Power connector: Uses the standard cord provided. Inside the DEQ 60 is a universal internal switching power supply that
accepts 100 to 240 VAC at 50 to 60 Hz, allowing it to work in most countries.

Graphic EQ Controls
Control each of the thirty bands of EQ with high resolu-
tion, 256 step slide controls. The center detent position
guarantees a flat response. Slide control travel is 25 mm.
Custom soft-touch knobs are comfortable and easy to read.
Perfect-Q™ filters guarantee accurate graphic response and
no band interaction.
The elimination of band interaction means the DEQ 60
EQ filters are suitable for “ringing out a room” and capable of
the very subtle adjustments required by the most demanding
user. Unlike previous designs that act upon a bandwidth of up
to one octave when cut 12 dB, Perfect-Q only affects the
intended 1/3 octave. For the first time, the user is able to
adjust a single 1/3 octave band with no affect on adjacent
bands. The lack of band interaction guarantees slider settings
accurately indicate frequency response.
For full details and comparisons to previous EQs, see
“Perfect-Q: The Next Step in EQ Design” included with this
manual.
