Behringer DEQ2496 EQ w/RTA Roadshow

Recommended Posts

I have a Behringer DEQ2496 Ultracurve Pro EQ with RTA available for a roadshow if anyone’s interested. It has a 31-band graphic EQ and auto EQ function. A Behringer ECM8000 microphone and XLR cable are included for use with the RTA. Forum membership and 200 posts required.

Zumbini has the unit right now, and is getting ready to sent it out. It has only balanced XLR connections, but Z has graciously offered to loan out some XLR cables and XLR-RCA adapters. He’s also printed out a copy of the manual (which I forgot to send emembarrassed.gif).

Cool Harryfan - these are nice - had one a while back. eusa_clap.gif
 
I have a bag of XLR-RCA & TRS/RCA adapters if anyone wants them.
 
Split the freight and the're yours.
 
Adapters gone - enjoy!!

This is a very capable and flexible unit and all that technology was a bit overwhelming AT FIRST.
It's an RTA, SPL meter, graphic EQ AND parametric EQ with adjustable bandwidth (1/100 octave to full scale).
It took me a week just to learn where all the screens and controls are but it was well worth the time and effort.
I would plan on keeping it for at least 2 weeks though a month would be better.
 
Thanks again for the loan Harryfan! This was the most fun I've had with a new toy in a long time!

You know what? I think I'd like to get on that list if Harryfan doesn't mind. It would be nice to experiment with to see if there's something I'm missing in my new audio room. Sure, it sounds good to me but I have no comparison at the moment.

 

Zumbini, I'll PM you my address and gratefully receive the DEQ with Harryfan's permission, of course.

How the Heck did I miss this! I would also like to be included on the list if thats OK. There has Got to be room for improvement and maybe it will be able to show me exactly where I need to add acoustic treatments.

I also use this for room equalization. The manual stinks, it’s awful.

Well, it’s a pity that this software is not able to control this equalizer. If it did, it would automatically generate all the parameters for the equalization. I’ve spoken with the author of this software to see if I could help and I cannot. It seems that the problem is that the Midi protocol implemented in the DEQ2496 is different of the protocol implemented in the FBQ2496 also from Behringer.

Otherwise it does a competent job for the cost. I’m happy with it.

I read the owners manual to this unit once. I realized this was not my 1970's slider eq. If I remember correctly, it also will compress and expand?

Now that Zumbini has planted the seed of lust in my mind over this thing, I've been reading the manual, which I downloaded from the Parts Express website.  It does appear that in the 'dynamic EQ' mode you can engage a compressor to reduce the volume above a selected threshold and an expander to reduce the volume below a  selected threshold.  So, yes, it can expand and compress the input signal.  RTA with parametric, graphic and dynamic EQ, digital delay, adjust width of the image by controlling channel separation---damn, it does just about everything but wash your socks.

  • Open architecture allowing future software updates via MIDI
  • 2 high-performance 32/40-bit floating-point DSPs for ultimate sonic resolution
  • 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)
  • Internal switch-mode power supply for maximum flexibility (100 - 240 V~), noise-free audio, superior transient response and lowest possible power consumption 
  • Dual 31-band Graphic Equalizers (stereo linkable)
  • Dual 31-band Virtual Paragraphic Equalizers (stereo linkable)
  • Dual 10-band Parametric EQ’s per stereo side
  • Dynamically-activated EQ
  • Feedback Destroyer with Learning Mode
  • Stereo Imager
  • Compressor/Expander
  • Limiter
  • Digital Delay
  • RTA/SPL/FFT Analyzer with Auto EQ function
Audio Quality / Clarity

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

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. 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.

EQ

Dynamically-activated EQ

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.

Special Feature

Feedback Destroyer with Learning Mode

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 dynamicallyactivated 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.

Ease of Use

Stereo Imager (WIDTH)

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.

Power / Wattage

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. 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.

Effects

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

Versatility

RTA/SPL/FFT Analyzer with Auto EQ function

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.

Ease of Use

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. 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.

Construction / Craftsmanship

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. 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.

Yes, that's kind of an interesting read.  I'd not seen that before.  Thanks for posting that, Jazzman.
It was concern about the analog-digital-analog conversion downstream that prompted me to pull this unit and the DCX2496 crossover out of my system and live with it for awhile.  Overall, my system seems a little warmer now but may be missing some of the punch it used to have.  Purely subjective observations.  Not really better or worse, just different.
The Behringer manual does recommend excluding frequencies up to 100 Hz from auto EQ (in that it may produce inaccuracies).  I'm wondering whether this guy's method of doing the lower frequencies separately would be more accurate.

I've been using a 10-band EQ to compensate the dipole phase cancellation and the diaphragm resonance in my hybrid electrostats.  I'm thinking the Behringer EQ's finer resolution would allow surgically attenuating the diaphragms' fundamental resonance (somewhere between 100-150 hz) without killing adjacent bass frequencies.
I guess I'll find out how well it works because I just went online and bought the Behringer DEQ 2496 with a mic, 25ft mic cable and XLR-to-RCA adapters.
All of you guys are enablers you know....

This DEQ2496 is a dandy little processor that I think I'm only beginning to fathom.  The jury is still out but so far I can make my system sound different in myriad ways.  Right now I'm stuck with "different" and have no judgement as to whether I can make it sound "better."  But it sure is fun to play with.

Questions:
 
1.  Do you have the unit between the preamp and amp or in your preamp's external processor loop or tape loop?
 
2.  Are you using the analog inputs on the Behringer or bypassing the unit's internal DAC thru the digital inputs?
 
I'm just curious because I just bought the same Behringer EQ, which arrived a couple of days ago.  I've got it hooked up in my preamp's external processor loop and I'm using the analog inputs, since I don't have a digital source to feed into it.  Unfortunately, I fried a woofer with pink noise right off the bat so now I have to wait for a new woofer to arrive before I can get the Behringer tuned in and hear how it really sounds.
