DEQ2496
ULTRACURVE Ultra High-Precision
Digital 24-Bit/96 kHz EQ/RTA
Mastering Processor
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.
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
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.

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.
Flexible compressor/expander
function with peak limiter per stereo
channel as well as additional stereo
imager and stereo delay for
delay line applications
The DEQ2496 is a whole rack of
flexible equalization, dynamics and
time correction functions designed to
fix problems and generally optimize
sound quality.
Unique VPQ (Virtual Paragraphic EQ)
option allows parametric control of
graphic EQs

Not only can you specify time delay
in feet or meters but simultaneously
compensate for ambient temperature
which affects sound speed!

DEQ2496
RTA/SPL/FFT Analyzer with
Auto EQ function
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.
Graphic equalizer with frequency response
correction (TRUE RESPONSE)
Easy to set up and use.
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.
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.
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.
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).
You can maintain up to 64
Everything you’d find on a dedicated
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.
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.
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.
Digital Delay
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.
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.
Graphic equalizer without frequency response
correction (UNCORRECTED)
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.
