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). 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.
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. 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.
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 Stereo Width (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 stereo width effect.
The DEQ2496 has a comprehensive set of dynamics processing tools that can be used as two independent channels or stereo linked. 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.
You can delay either the DEQ2496’s Main or AUX outputs anywhere from 0 to 300ms and can process left and right channels independently. Not only can you specify time delay in feet or meters but simultaneously compensate for ambient temperature, which affects sound speed!
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). 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.
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. 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.
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.
Quite frankly, we believe that the DEQ2496 is the best multi-function processor value in the pro audio industry. So, why pay much more for a status name?

Panel Features:
1.) The LED METER indicates the DEQ2496's input signal.The top CLIP LED lights up as soon as the input signal level is too high or the peak limiter in the Dynamics menu.
2.) Use the METER key to select the METER menu.
3.) The DEQ2496 features a built-in real-time analyzer displaying the entire frequency range.Use the RTA key to select the corresponding menu and adjust the various settings.
4.) Depending on the currently selected menu,the COMPARE key allows you to compare either complete presets or individual modules.
5.) Press the MEMORY key to select the MEMORY menu
6.) The PAGE key allows you to select the various pages within one menu.
7.) The functions performed by the keys A and B depend on the selects menu and are indicated in the display,
8.) This is the LC display of your ULTRA-CURVE PRO.
9.) The DEQ2496 has three DATA WHEELS,which can be used to select and edit various parameters-again depending on the currently selected menu.
10.) With the menu keys you can select the individual menus of the various modules.They can also be used to select specific pages from these menus.
11.) Use the POWER switch to put the DEQ2496 into operation.This switch should be set to "OFF"before you connect the unit to the mains.
12.) The FUSE HOLDER holds the mains fuse of the DEQ2496.Blown fuses must be replaced by fuses of the same type and rating.
13.)The mains connection is made using the enclosed power cord and a standard IEC receptacle.
14.) The MIDI jacks enable the DEQ2496 to communicate with a computer or other MIDI equipment.Incoming MIDI data are received on the MIDI IN,outgoing MIDI data are sent via the MIDI OUT.Received MIDI data are also present at the MIDI THRU jack,so as to pass them on unmodified to other devices.
15.)Use the WORDCLOCK input to synchronize your DEQ2496 to external equipment via a wordclock signal.This connector is on a BNC coaxial jack.
16.)Your DEQ2496 features a digital optical optical interface for the transmission/reception of data in both AES/EBU and S/PDIF formats.
17.)The digital AES/EBU interface (XLR connectors) also sends/receives AES/EBU or S/PDIF signals.
18.)The AUX OUT phone jack is an additional stereo output,which allows you to tap the audio signal present at the digital outputs in analog form.
19.)The RTA/MIC IN XLR connector can be used to connect a measurement microphone providing an input signal for the real-time analyzer or SPL meter.
20.)The MAX switch raises the maximum level present at the MAIN inputs/outputs from +12 dBu to +22 dBu.
21.)These balanced XLR connectors provide the analog output signal of the DEQ2496.
22.)These balanced XLR inputs are used to connect analog input signals.
