ULTRA-CURVE PRO 	
DEQ2496
ULTRACURVE Ultra High-Precision
Digital 24-Bit/96 kHz EQ/RTA
Mastering Processor
Ultra-high resolution processor for all
EQ, RTA and dynamic applications,
especially for PA and
audiophile mastering
4 concurrently selectable EQ modules
(31-band graphic EQ, 10-band
parametric EQ, Feedback Destroyer
plus 3 Dynamic EQs per
stereo channel)
Flexible compressor/expander
function with peak limiter per stereo
channel as well as additional stereo
imager and stereo delay for
delay line applications
Unique VPQ (Virtual Paragraphic EQ)
option allows parametric control of
graphic EQs

The DEQ2496 is a high-precision
digital 24-bit/96 kHz EQ/RTA mastering
processor, ideal for sophisticated live
sound trouble-shooting or audiophile
mastering. Whether you’re putting the
finishing touches on recorded material
or creating an optimal live sound for a
multi-way PA, the DEQ2496 is built to
provide meticulous control.

Dual 31-band Graphic Equalizers, 	
31-band Virtual Paragraphic Equalizers 	
and 10-band Parametric.

Equalization? Dynamics? Feedback
correction? Yes, yes, yes. You can have
it all with the DEQ2496. Automatic
FFT analysis with Auto EQ? We added
that too.

Naturally the DEQ2496 has phase-neutral
digital graphic EQ…but in addition we’ve
added a function that allows you to change
the bandwidth of each frequency from
standard 1/3 to as much as 59/3.

The DEQ2496 is a whole rack of
flexible equalization, dynamics and
time correction functions designed to
fix problems and generally optimize
sound quality.

Ultra-high resolution 61-band

DEQ2496

Or, if you prefer the old-school
approach to variable bandwidth, we’ve
included 10-band parametrics that can be
fine-tuned in increments down to 1/60 of
an octave.
Dynamically-activated EQ

Ultra-high resolution 24-bit/96 kHz
A/D- and D/A converters
(113 dB dynamic range)
Open architecture allowing future
software updates via MIDI
2 high-performance 32/40-bit
floating-point DSPs for ultimate
sonic resolution

Dynamic EQ automatically raises or
lowers a defined frequency range based
on volume level. It’s literally a
combination of an equalizer (with
frequency center and bandwidth controls)
and a dynamics processor (with ATTACK,
RELEASE, THRESHOLD and RATIO
parameters).

With the digital capabilities we’ve just
listed, it’s easy to see why we were able
to include a highly-effective Feedback
Destroyer (FBD) feature — it’s essentially a
dynamically-activated parametric EQ that
“watches” the whole frequency spectrum
in 1/60-octave bands and then instantly
identifies and notches out feedback.
FBD can be run in AUTO mode
to compensate for movements of
performers on stage, or in SNGLE mode
that locks onto individual frequencies and
then varies the amount of attenuation
and bandwidth depending on feedback
stimulus — more suited to fixed
microphone installations.

Balanced inputs and servo-balanced
outputs with gold-plated XLR
connectors, stereo aux
output, AES/EBU and S/PDIF inputs
and outputs (XLR and optical)

We also included a LEARN mode that
generates short audio pulses, raises their
gain until feedback occurs and then
locks into potential trouble-causing
band centers.

Internal switch-mode power
supply for maximum flexibility
(100 - 240 V~), noise-free audio,
superior transient response and
lowest possible power consumption

Stereo Imager (WIDTH).

High-quality components and
exceptionally rugged construction
ensure long life

DEQ opens up a world of both creative
mastering and PA problem solving
possibilities. We’ve given you total control
with multiple filter types including
bandpass mode. And of course you can
store DEQ settings for recall at any time
manually or via MIDI.

Conceived and designed by
BEHRINGER Germany

Feedback Destroyer with 	
Learning Mode

While usually considered a mastering
technique, the ability to widen the stereo
image can be useful in live sound work,
too. When you hear it in action, we think
you and your audience will be impressed.

The DEQ2496 WIDTH processor provides
control over STEREOWIDTH (how clearly the
two sides of the stereo image are separated
from each other), ASYMMETRY (relative volume
of left/right stereo signal), ROTATION (panning
of stereo + mono in the stereo image), and a
multipart SHUFFLE function than can generate
an additional low-frequency Stereowidth effect.
Compressor/Expander and Limiter
The DEQ2496 has a comprehensive set of
dynamics processing tools that can be used as
two independent channels or stereo linked.

Not only can you specify time delay
in feet or meters but simultaneously
compensate for ambient temperature
which affects sound speed!
RTA/SPL/FFT Analyzer with 	
Auto EQ function
Graphic equalizer with frequency response
correction (TRUE RESPONSE)

Easy to set up and use.
The DEQ2496 features an FFT real
time analyzer for precise graphic display
of 61 frequency bands. You can monitor
main or digital inputs and outputs,
AUX/digital out or a feed from an RTA
microphone and display the results in a
multitude of ways including funky retro
VU meters.
You get all of the usual peak/hold,
display rate and scale features you would
expect from a professional measurement
tool, plus our user-definable AEQ (Auto
EQ function), which allows you to analyze
and adjust your system’s frequency
response automatically (perfect for
“roughing out” initial room adjustments).

The DEQ2496 has balanced inputs and
servo balanced outputs with gold-plated
XLR connectors, stereo aux output,
AES/EBU and S/PDIF inputs and XLR and
optical output. Configuration is intuitive,
with on-screen block diagram displays
and you get a separate RTA mic/line input
with phantom power, a professional
wordclock input and MIDI connections for
full remote control, as well as preset
dumps and system updates.

Digital Delay

You can maintain up to 64
comprehensive user presets at a time
and of course dump and load as needed.
You can also save and recall individual
modules such as DEQ, PEQ, WIDTH
or DYN. These subsets of complete presets
let you maintain most of a preset’s
settings but vary a few (such as graphic
EQ) without having to generate a whole
new preset.

You can delay either the DEQ2496’s Main or
AUX outputs anywhere from 0 to 300ms and can
process left and right channels independently.

Built tough for the road,
precise for the studio.

Everything you’d find on a dedicated
compressor/expander is here including variable
rations from 1:1.1 to 1:100, ATTACK times from 0
to 200ms, 0-3dB variable knee and 20 to 4000ms
RELEASE, all adjustable from a coarse/fine
adjustment scale. The built-in separate LIMITER has
Threshold, Hold and Release functions.

In Graphic EQ mode, you can choose
between UNCORRECTED response,
which shows the mutual influence of
adjacent bands, or select TRUE response
to apply a specially developed algorithm
that displays the actual results of the
equalizer setting.

Graphic equalizer without frequency response
correction (UNCORRECTED)

The DEQ2496 features high-quality
24-bit/96 kHz A/D and D/A converters
and two high-performance 32/40-bit
floating-point digital signal processors
for incredible sonic resolution and 113 dB
dynamic range.
The internal switch-mode power
supply assures maximum flexibility
(100-240V~), noise-free audio, superior
transient response, lowest possible power
consumption and freedom from power
surge damage.
