Room Acoustic Equalization/Correction with Behringer Ultra-Curve Pro DEQ2496
ฝัง
- เผยแพร่เมื่อ 17 ส.ค. 2017
- Apart from having great sounding studio monitor speakers, to achieve a well balanced mix, it is important to have balanced acoustics in a room as well. Even the best speakers will sound different when placed in a different size and shape room.
To achieve a balanced room, you still need to ring-out the room to find out the response of the speakers and then adjust to correct it.
One way of achieving this outcome is to use Pink Noise to ring out the room and use Equalization to correct it. And the easiest method is to use Behringer's Ultra-Curve Pro DEQ2496.
The Behringer's Ultra-Curve Pro DEQ2496 is a digital (24bit/96Khz) equalizer and dynamics processor that can be connected between the Audio Interface Studio Monitor Outputs and the Studio Monitors' Inputs to digitally EQ the speakers.
In this example, I demonstrate how the DEQ2496 works and affects the speaker output to give me a flat response. I use Room Eq Wizard to test the results before and after.

Thanks for the demo, I have a few comments that might help you in your journey.
1) That initial dip in the 75hz region is typically found in the center of the room and is called "the center null". The center null is caused by the corners reflecting the low frequencies back to the center. The treatment you are doing in the corners will not attenuate the lower frequencies. A few limp mass absorbers could help, and those can be built fairly cheaply. Limp mass absorbers are built tuned to a specific frequency range. If you are able to tame the lowest frequencies, then their harmonically related frequencies up higher will also come into line. There is a fellow named John Brandt, that can help you with specific room treatment options, but honestly in a small room, like the one that you are in, you won't be able to do much about it by treatment, as the treatment will eat up too much of your room space.
2) Ideally your best listening point is about 36.5% from the front or back wall. The center should be avoided for both measurement and listening/mixing unless you are using point 4 below.
3) The thing that will mess up your mixes is how long those frequencies hang around. Using the REW application you can display those with the "waterfall" function.
4) There is a third option (besides EQing the signal and surface treatment) for killing the center null. That option is placement of subwoofers at the corners or centers of the walls. It takes four subwoofers, but will create a zone in the center of the room that is much flatter in the low frequencies.
5) Mixing in the cans (headphones) might actually be your best option. Waves nx can tune your headphones to the measurements of your head and specific model of headphone. This will give you a 3D spatially referenced mixing experience. This is probably the cheapest option and should give you the best mix outcomes apart from building a room with the proper ratio's etc..
Thanks for your detailed comment. I have now used option 1 and this has reduced that dip quite dramatically. Using Sonarworks Ref 4 helps even further, but not 100%.
As you mentioned, any room size like mine, there will always be issues, so you get to learn them and correct them from experience.
Or,
I can go in the middle of the desert with no walls :P
P.S. John Brandt helped me during my studio soundproofing stage. Again, due to the restricted size I could build, I had no choice with the internal acoustic response. It would eat up half of my already small room!
This was amazing. Thank you. 5 years later, I am about to own a DEQ2496 for my room and I can't believe how perfectly helpful and educational this was.
You're very welcome!
Remember, correct room acoustic treatment is recommended before fine tuning of DEQ2496
@@teckno_senpai Room treatment is the first option. Room correction is the finer details of that room treatment. No room treatment, DEQ2496 can make it worse. DEQ2496 is balancing the tone, Room treatment is not only balancing the tone but also room reverberation, resonance build up and more.
DEQ2496 is the polish application of a car paint job :)
The best way to position the microphone directly in the centre is to:
1. Play mono whitenoise
2. Use a spectrum analyser (a plugin like Pro-Q 3 is a good one)
3. Move the microphone left and right in small increments
What you'll see on the spectrum analyser is the comb filtering artifacts (big nulls in the frequency response) moving across the spectrum. When the microphone is equidistant from both speakers, the harsh nulls in the spectrum will disappear. This technique is by far superior to the tape measurement technique, where one measures the distance from each speaker to the microphone with a tape measure. It'll give you a much more accurate frequency response measurement when using both speakers at the same time.
Hope this info is useful. Thanks for the video. :)
Makes sense. I MUST try it one day. Thanks for your valued comment.
@@RecordingStudio9
You're welcome. I stumbled upon it when setting up my studio room. I found out that moving the mic a few mm either direction is enough to see comb filtering artifacts. It improved my frequency response measurement once I had it set up perfectly. 👌
That was pretty slick, thanks for showing this. Really like the digital eq.
Thanks. You can achieve similar result with software EQ as well, like EqualizerAPO.
wow this is amazing I have been looking everywhere for a good descriptive video on how to set up my mic and use REW ! thank you :)
very helpful... excited to get my hands on DEQ2496 very soon!!
Fantastic tutorial. Thank you so much for doing this.
Thankyou for the revive, it realy saved my life, it’s now been 15 days buying and useing the behringer deq2496, auto room correction corrected my Major room faults and flatten my Adams A7 monitors, especially 160hz and 400hz was to much hearing inside the room and the phaze problem after the 10Khz, now i’m succeded with my mixis. Thank you.
160Hz & 400Hz can easily be corrected using acoustic panels, which is better option and give you wider listening sweet spot, then the DEQ2496 can level it perfectly, to +-3db.
So you take a picture wearing a mask. Wtf
This is incredibly helpful! Going to use that unit to treat my music room
Glad it was helpful! This video might be a great follow-up th-cam.com/video/8Y5vvE61Lic/w-d-xo.html
Dobra robota. (good job) greetings from Poland.
Very clear explanations, thanks
Thank you for this video, I am tryng to flatting the response of my speakers with only the tone controls because I haven't an EQ like yours and I can see the graph of my speakers changing in the right way...I see a limitation on the mid frequencies I think is due to the nature of the speakers, I use Creative Gigaworks T20 (first version) they sounds good but is clear that the mid frequencies are a little under the bass and the highs, are lower around 6-7dB than others frequencies but I think is a good result for the price...
Thanks for the video! Wishing you make a tutorial of stereo system include one subwoofer!
Very helpful thanks !
Great video thanks
Great video... Good starting point...Now get Dirac room correction and experience time domain correction as well... Much much better focus and sound stage when you deal with temporal distortions, which simple EQ cannot.
Thanks for the comment. I already use Sonarworks Ref 4.0 Pro.
nice process
Thank you very much.
Excellent thanks
I'm your fan
Thanks a lot!
Thanks for the amazing video. Ever experimented running response tests while you are sitting at different positions. I wonder if you block some reflections from the wall and alter the test results when you sit close to the mic.
Here is a video of testing the speaker response in my room from 2 different locations. th-cam.com/video/Lr1xkWJexP8/w-d-xo.html
Interesting video. But it's not clear to me what happends around 7kHz. If you eq both added it's only ok in a mono situation. May be you can try inverting the fase of one of the tweeters and equalizing each one separated. Thanks
Thanks for the very informative video. I would like to see more in depth videos on the fantastic DEQ2496. There are a few scattered around but your step by step method is easy to follow. So, how about starting with the feedback removal and the DEQ features. Keep up the good work. 👍🏼
The DEQ2496 is quite a complicated unit. Some parts, I'm not even 100% confident. I'll see what info I can give out.
could there have been any absorption with your body to one side of the mic? Love your vids btw, you are always incredibly clear and so are your processes.
Thanks for the feedback. Not sure as I was not inside the triangle (I think) , but since both speakers, when measured separately showed very close similar results, I'm not sure that would have been the issue with 7Khz slight dip.
Very nice thx 👍
Welcome 😊
Can the older Ultra Curve DSP 8000 do the same room correction processing? (The 8000 manual says it can do RTA (real time analyzer))?
It's a secret!
Great video content and delivery! I am using 2 JBL 305's with the JBL 310x Subwoofer. Both 305 are plugged into the 310 subwoofer... Would the DEQ2496 work with this setup? Thank you!
I have a question, how do you setup the microphone gain in your audio interface? I am using Behringer XR18 as an audio interface and would like to do the same test.
My experience with the Behringer DEQ2496 is completely different. I performed a room EQ in my studio with Genelec 1032 speakers, and after the room EQ everything sounded worse than ever before! I used a Daytona measurement microphone.
I removed the DEQ from my setup and now I am happy again with the 'old' (uncoloured) sound!
(I sold my Behringer DEQ2496 in the meantime.)
I have the same experience with room EQ equalizers.
You simply can''t tune a room or speakers like the pipes of an organ...
Your room is the one that colours the sound.
Isn't that why they call it "Room EQ"?
I have tried this before and everything sounded worse after using the DEQ2496.
After removing the DEQ2496 from the signal chain, the sound came back to normal.
And yes, I used a good quality calibration microphone!
Maybe we just don't `hear` like mics do.
How long did you folks live with the "fixed" room EQ? Of course it is going to sound like crap after fixing it because we are use to the bad sound. Live with it for a week or so, remix some tracks you are happy with and compare them out in the real world (car, living room, etc) and then make a judgment.
also, i have a question... if I am finalizing everything in my DAW logic pro, and if i want to utilize mastering plugins like izotope ozone, how should i best apply my DEQ2496 in my workflow? I am a producer/artist using outboard gears to make music, and all the signals flow through some compressors like FMR RNC, Elektron Analog Heat and ART PRO VLA II (for vocals). I am not quite sure where DEQ2496 fits and shines the best. My initial plan is to sum everything and run through DEQ2496 as the mastering chain before it hits my DAW. My curiosity is if it would be better to sum everything to my DAW first, then run through DEQ2496, making the final output come out from an analog gear...
Without fully understanding your workflow, I can't comment on your question, but one thing I can mention is that the DEQ2496 is not analog. It converts inputs into A/D 24bit/96Khz digital audio, process and back D/A.
It's a great mastering processor for its time, especially for live performances, but these days I use it as my hardware room correction section only. But having said that, being on my patch bay, I can use any of its processing as an outboard gear in my DAW.
Hey man, thank you for this amazing video! Loving that DEQ2496. What do you think about room correction programs? Lately I've been demoing the sonarworks reference 3 Do you think the results would be comparable or would one be better then the other?
I didn't already buy it but for educational discounts I would get the reference 3 for about € 150 which is €100 less then the behringer. What do you think?
Thank you in advice
Thanks for your comment. I haven’t tried Sonarworks yet, but have plans to demo a copy.
One advantage of DEQ2496, it’s a hardware just before my speakers, meaning I can never forget to have it on, and I don’t have to worry about disabling Sonarworks on my master bus when I’m exporting/printing my song.
RecordingStudio9.com And thank you for answering too!
Yeah, that's the first thing I tought... reference 3 can be set to work on all you computer system, which is a good thing (same thing as u said)
Reference on the other hand can also be used to change the speaker/ headphone frequency response to emulate other monitors
Give it a try ;)
Is there any way to get the eq correction from the deq2496, so we could use any equalizer, and use the deq2496 for another room/occasions.
There are user preset you can save the eq curve and recall.
Hi ! excellent video and thank you very much for it I have a silly question ... the sound from the speakers with equalization is clearly better than without ? It would be interesting to listen to a same track equalized and not equalized Some purists say that equalization is bad We dont ever see equalizer at high end audio fairs for instance I am still confused Thanks again and kind regards, gino
EQ-ing your speakers does not mean clear audio, but more balanced. Speaker EQ is the last final balancing of the speakers to the room. If you don't already have proper room acoustics, EQ is pointless. It's like the seconds hand on a clock, without it, you can still tell time, but you get better resolution. But with no hour and minute hands, seconds mean nothing.
Most high end studios have speakers with built in DSP that correct the speaker EQ to the room.
Hope this answers your question.
Great video presentation. I was just wondering if you've had any reliability issues with the DEQ2496. I've been through 3 of them since 2006 - each has had some degree of quirkiness. The current one mutes the speakers shortly after powering up. But as soon as I turn it off and back on, the unit runs fine for the duration of my performance. (I use it for live performance.) Your thoughts please.
I have to say, I have not had any issues thus far and I had it for a few years now. It's on most of the time. But since I got Sonarworks Reference 4 Room Correction software, it's been off.
The three DEQ2496's I've had were pretty early versions (circa 2006-9,) so maybe the more-recent units are a bit more reliable. I'm thinking of getting another one for backup, 'cuz there just isn't anything out there comparable!
Hi Vatche, i have the same Monitors (Eris E 8) did you change anything in the back? I'm thinking of getting the IK MUltimedia System ARC 2.5 to calibrate my room.
I have my setting at -4db since they are close to my back wall. Other than that, all default.
Hello. do you know if it is possible to create a negative correction curve? selecting maximum +2 or 0 and correcting most frequencies for example -3 -4?
Yes, you can set the gain/reduction amount for all frequencies as one setting, eg. only apply +3/-3 db max. You can also manually update the gain/reduction amount for each band after.
Bought the behringer ultracurve long ago couldt figure out how to work it until now. Thanks
Do you think the behringer ecm8000 its a viable option?
Me too!
This tariq i m using pa800 arranger and using daw calke walk sonar x3 but its not sync to daw plzz help me sent video how i sync.
This video might help you th-cam.com/video/wXD5qjEafSQ/w-d-xo.html
Hi, does the Ultra Curve Pro DSP8024 the same as your DEQ2496?
Yes, pretty much, less the added features in the DEQ2496 like compression etc.
Hi. I have 2 audio interfaces in my little room. Both only have stereo outs. Can I take the output from say the left and route it into one of the input channels?
You will loose 1 input and one output. This video might helkp you better option. th-cam.com/video/EczMDEFZdRM/w-d-xo.html
im thinking to buy this to use with with my home theatre for my subwoofers would it be easy to set up as a sub filter ?
You might need an Active Crossover unit, not DEQ2496. Just Google Behringer Active Crossover and choose a model that suits your needs.
Tnx man
When yo did this calibration missions, your speaker calib sittings they was flat or what?
Yes, and no. The speakers have room wall proximity switches as well as bass & treble gain levels. I have the room switches set to the correct setting and the gain levels to 0db.
I also have my audio interface volume set to mid point and adjust the speaker's input gain till I get about 75db, this way, I can always have my interface volume same position and expect the same level from the speakers.
Hi Vatche,
Mere curiosity... do you believe that the ultracurve eq creates a different auto equeing for left and right or just a main stereo one?
Thank you
As far as I'm aware, it is a link stereo processing, so you can't set left or right channels individually. But I will investigate further.
@@RecordingStudio9 thank you. This info would actually be much appreciated if you find the time ;)
the left and right channels can be set individually
Very interesting. I looked up a wavelenght frequency calculator. At 7k the wavelenght is 4.85 centimetres, so half that lenght is 2.425 cm. Is it possible that the speakers and the microphone are not perfectly aligned? 2.42 centimetres off would be enough to cancel the signal
Possible. I have not investigated further.
The idea is to get as close to flat response as possible, then train your ears to learn the response of the speakers to audio.
I am new to all this, but that is the question I was asking myself, is a very specific microphone position now optimised
Right after the process do you unplug the mic and put it away? I wouldnt imagine you leave it not sure when in the process to unplug it
Correct. Once measurement is done.
Halo, I just bought DCX 2496, how do u run pink noise? do i need to connect to a PC? Thanks
No offence ment, but you just purchased a complex and expensive audio gear with no clue on what it is and how it works, SO, read the manual.
I do have another video on my channel that might help.
Hi! Can you equalize your speakers to colorize your sound to emulate a hifi equipment? Then you save it as a preset so you can switch from a flat studio sound to a more pleasure-oriented hifi sound using the same speakers. Thanks!
Yes you can with DEQ2496, as it has settings memory store and recall.
@@RecordingStudio9 thank you!
How does this compare to minidsp hd
How can I use the measurements later in an equalizer. Is there an equalizer that can use that
For DEQ2496, it already has built in EQ to correct. For REW, here is the video you may find helpful. I use a software to EQ the audio output of Windows Audio th-cam.com/video/8No1v__3Pr8/w-d-xo.html
hi, nice video. you use the yamaha ag03 in this video. how do you calibrate it with the room EQ wizard?
Link the Left TRS output to Mic Ch1 line input and adjust the gain with the mode switch in Dry position.
hi thanks, which cable do I need and are settings EQ wizard AG06 / AG03 default output and default input oké?
Nice Video Sir I hàve a question before this lovely thing would I be able to store different graphic equalizer settings for example all 1 1 1 flat frequency graphic equalizer to page 7 , increase low frequency graphic equalizer to page 8, increase low mid high frequency graphic equalizer to page 9. Now supposed I playing a song would I able to load any of this save page like 7 setting or page 9 setting with stoping the song. I thank you in advance for reply
Yes, you can. It does have lots of user settings save options.
@@RecordingStudio9 Thank you very much appreciated. Your reply was Supper fast. GOD BLESS YOU
So for us normal people... Does room EQ offer an equalizer that we can correct the room ourselves by moving sliders? Or does it have any auto calibration functionality? Can we then leave it on in a PC so that all music played through the PC will be room-corrected? ... Would this sound better than say Audyssey XT32 built into my receiver? Is it a better replacement for me to buy an $80 microphone and download free Room EQ?
Your first option to balance your room, is to use appropriate Acoustic treatment and panels. Once you have done that, or you like the "lazy" option, then this video might help you. Use Room EQ Wizard and Equalizer APO software th-cam.com/video/8No1v__3Pr8/w-d-xo.html
Have you found the best place for the speakers in the room? This could possibly improve the frequency response even further.
I can keep searching for a perfect position for my speakers, if there is such a thing, or look at the practical side and adjust my senses to it. 😊
HEY MAN ! do you think you could show me the link for the room eq wizard videos ? I can't find it ahah you have a lot of videos !
th-cam.com/video/dYOlC1onguI/w-d-xo.html
Sir i only have one condenser mic so can i use it to measure my room !!
You need a measurement reference microphone, not just any microphone.
Is this product overkill for just hooking up to a 2 channel stereo amp?
Depending of its purpose. Possibly.
Do you see every band changes that is made in decibels?
Yes, once the measurement is complete, you can go and edit any of the 64 bands in 1db increments. You can also choose the frequency range to correct. Eg. If your speakers won't go any lower than 50Hz, there is no point trying to correct 20Hz as it will never get there and might even push the speakers beyond capability.
Do you need a computer to get good results or is it for showig us the difference?
Showing the difference.
Can you eq each speaker individually?
As a digital EQ, not RTA, yes.
I don't know why, but it's callibrate and turn HF too high and LF too low, even with Room Correction- doesn't matter. ECM8000 sounds nice. I callibrate with parametric EQ and Sweep-tone manually. Sounds acceptable flat. (Tannoy 802)
Room correction software is NOT your secret weapon!
Alas, you can’t simply apply digital room correction to fix your acoustics.
Room EQ can tame some issues, but it can’t correct for long reverberation times or comb filtering caused by strong early reflections (like those nasty reflections produced by speaker-boundary interference).
To tame these problems you have two weapons in your arsenal: smart room layout and acoustic treatment.
I don't think he said Room EQ is magical. But with very small rooms acoustic treatment is simply IMPOSSIBLE in the bass region. It requires lots of space and bass traps in the corners are not magical either. You need to treat mediums and highs for sure but bass in home studios will benefit a lot more from EQ than putting bass traps like I see in the video. It's still better than no bass traps though but in my experience small rooms have HUGE modes in the 50-100hz range, wherever you seat in the room. Anyway Room EQ for the win unless you mix in a >25m² room (unlinkely to happen in a home studio).
Will it process variable volume levels or fixed only?
Best set at around 75db listening levels
What I mean is where in the system thus should be installed, between pre and power amp or between source and pre amp?
@@robertj606 Your question should have been "Where in the signal chain do you place DEQ2496".
The unit is Line Level in and out. I have it on my patch bay, normally between my Audio Interface's output and powered speakers' input. But, I can also patch it to be used as hardware EQ, Compressor, Gate, Stereo Image processing.
For speaker management, it should be before the powered speaker or amp that drives passive speakers.
Never thought about it. I purchased Sonarworks Monitor Reference and its pretty good. Have you tried it ?
I know of Sonarworks and ARC 2 by IK Multimedia do it in software, but the great advantage having it in hardware that, I can plug any audio player into my patchbay and listen with flat response, compare and adjust etc.
RecordingStudio9.com Yes. I wish you would've uploaded this video a couple of months before. This is a much practical solution. I've seen this eqs for less than 200 us dollars. Might give is a try and add it to the sonarworks chain.
By the way.. What do you think about Sonarworks?
Your studio is looking great!
What is better? Sonaworks or Behringer ultra Curver to get flat frequency response?
I use Sonarworks during mixing, but because my ears are used to the Ultra-Curve Pro, I master with them on (Sonarworks off). DEQ2696 being hardware, I don't have to worry about adding plugings and remembering to disable during mixdown/rendering etc.
@@RecordingStudio9 thx. I have sonaworks reference only for my headphones. And now , price for Deq2496 is almost the same like price of sonaworks . What is better to buy?
And with one is more useful ?
@@ilumovieminaty8085 It's a personal workflow thing. It's up to you. One thing I would add, is that Sonarworks is a new technology compared to DEQ2496.

Good music director
I'm not a sound guy, but I've always loved sound, sound effects and of course music. I couldn't help but notice how much your equipment reminded me of my job which is often as a network engineer. The patch panel and the rack and the networked equipment, hah -it was like the Bizzaro World version of what I do. I wondered if you might be able to direct me to some easy to learn resources on what it is you know. I like science, and technology obviously isn't a problem for me. I thought I'd take this on as a hobby perhaps and if I'm any good... well, I'll cross that bridge when I get to it. Like my Commercial Graphics degree (that is hardly used) I don't usually regret the things I learn and find ways to make use of the knowledge.
It's 5db dip at 1/3 octave smoothing, but in reality it's more like 25db dip...no smoothing and 1/48 give accurate results. One tip i can give to people staring out is....You need to treat room with broadband absorbers, bass traps....even before you start thinking about room correction software. Acoustical foam captures only hi frequencies and it's useless in the bass and mid area. When you eq your room, eq only peaks, big null (dip) isn't very clever to eq....dip is made from phase cancellation, room modes...You will be amazed how speaker positioning can even out the frequency response.
Thanks for your comments.
One thing people watching this video is that, they have not watched my prior or follow-up videos talking about room acoustic treatments.
Also, when I did this video, I had just finished building my studio and there are no acoustics installed yet, hence the big peaks and dips in the graph shown.
Yes, the EQ is for final fine tuning. I normally run it when I add or remove objects in my studio, like a drum kit or a shelving etc.
Your accent sounds half british/aussie and half italian?
1.5x speed flow smoother for me
I heard EQ'ing doing above 250 Hertz is not very good
True. You need to be gentle with settings above 250Hz so you don't effect the curve too much.
The room treatments on your walls does nothing suppressing echo. Your voice is echoed all over.
My room is as much a "live recording room" as a control room. I don't have all my walls covered with absorbers and reflectors. My drums sound real punchy and live at the same time.
Thanks for watching.
I'm India from Punjab Patiala
So? Who cares, really.
I'm sure he is just saying hello from India.
You could easily be trying to correct room modes here instead of unflatness - in fact, listening to this room, I can guarantee it. You need to take multiple measurements on each speaker, moving the microphone all around your listening area, then average them all. That will give you something closer to what you really need to equalise. And of course what you are actually equalising is your speakers. You can't equalise a room.
While I agree with your comment, it is near impossible to have perfect room, no matter what acoustic treatment or speaker equalisation you apply. You try to get close and then over time, learn your speakers and your room response.
You are sitting in front of the right speaker. So the rooms resonance is not correctly measured and it looks like the right speakers curve is way better. 😉
I guess you can say I have a 'good influence' LOL
thats the frequency response of your room ..not your speakers
It’s the response of those speakers in my room, generally average room size of a bedroom, unless I place them in an Anechoic Chamber. But, I get what you mean. If I place a $50,000 reference speakers, then I will get my room response close to 99%, then again, the speaker placement will still make a difference.
It’s about getting as close as flat and teaching your ears 😊
RecordingStudio9.com yeah as i am trying to flat my Bluetooth speaker, i realized that where i place the microphone is different, i just forget it to flat many others speaker
Are you a fireman?
Different speaker Different watts
Your room is very boomy
Most small rooms are. With the correct room acoustic treatment of low frequency absorption and fine tuning with EQ, will end up balanced.
Let me tell you , aint no way to get flat response in a Room . If you Correct it for one position , move a little and then its even worse then it was . So , if you are not going to move your head not even 1cm , then ok . But who does that while listening to music .
So , that is impossible to do . Its possible to measure the room and then make a camera to falow you then send you position to DSP and then EQ it for your position ,but that is very complex .
• "Flat Response" is always referanced as average levels, within a 12db dynamic range along the frequency spectrum.
• The 1cm distance you reference is dependent on the frequency you are measuring. Eg, low frequncies have wider area then high frequencies, which are more directional.
It all depends on first finding the best listening position in your room and then placing the speakers for best results before any acoustic treatment or EQ.
After measuring your room renponse and managing issues with acoustic panels, using some type of EQ correction will try to further adjust the response for certain frequencies with extreme peek or dips and bring them to managable levels, at the listening position.
And finally, once you have good average result, you train your ears to learn how your speakers react to sound to make the best judgement during mixing.
Thanks again for your input.
That is not done like that!!!
If you have to equalize some studio monitors, what is really wrong is the acoustics of your control room. Start by correcting the acoustics of the room first.
This process allowed me to locate the problem frequencies and correct them with acoustic panels, otherwise you are blindly placing panels.
When you speak, your room sounds very boomy....it's very revealing. You have some work to do, fixing the acoustics.....
Yeah foam especially on first reflections isn't going to cut it. Even less so when its a small area.
Doesn’t sound boomy in my small 2€ headphones.
sorry but there is NO way you can get anything CLOSE to 'flat' from ANY loudspeaker - especially in that proximity to the wall and esp. sitting on a SHELF .. ludicrous

yes i can appreciate that - we all live and learn - technically speaking you COULD 'equalize' for just about any situation - even having a speaker driver firing down a copper pipe. or keeping it underwater ... and it might even work for room analysis software ... but audio signals and room interactions are a lot more complex than that ... and when we have some really 'live' resonators in the room - it's going to affect the end product in a fairly harsh way ...I just wanted to point that out so people could avoid battling demons they might not need to if they pay attention to the setup first - there are lots of pretty good guides on doing so out there - a lot of really horrible ones too ... i've been struggling with these issues for thirty something years now since setting up my first studio. there's quite a lot of tail chasing involved! good luck to everyone
Your room sounds too reverberant, you need to treat your room more.... best luck
Yes, because then I had just moved into my new studio.
@@RecordingStudio9 great!!! good luck at the new studio
I can already hear that the acoustics of the room you are in are horrendous.
That's because this video was made just a week after I finished constructing/building my studio and there are no proper acoustics. Perfect way to demonstrate the process.
This process allowed me to locate the problem frequencies and correct them.
Lol, why to make a video about smth you don't understand a crap. If you read 1 SINGLE decent article or book...oh man, trying to solve time event by correcting amplitude...good luck

Maybe you can teach me. Let's correct time event, I'm listening...
Sure, but not for free. Cause I see dozens of fails just from your room setup and methods - that's will take a while.
That's what you making by EQ the time matter - non-minimum phase.
So you telling me you cannot even sum it up in a sentence? Must be a big secret.
Have you read manual from REW? Nope
I've explained in my first comment.
The DEQ2496 is a piece of crap, like all Behringer products! I've tested it at my home and concluded that the DACs are crappy. The miniDSP 2xHD sounds much better.
With DEQ2496, you don't need a PC to set it up. It does lot more than just EQ. Never had any issues.
You noticed it comes with a digital input and output? Hook up your own DAC! I actually have a miniDSP 10x10HD as well and use the DEQ2496 as a loopback EQ for it.
I personally don't use the digital option myself.
The Behringer uses Asahi Kasei AK4393 dac chips which are used in a lot of high end studio equipment. You may not like the unit for any number of reasons but the dac chips aren't one of them. The primary complaint with the DEQ2496 is that it's a 10 year old design which hasn't been updated since it was introduced. BTW the miniDSP 2xHD uses an AK4396 dac from Asahi Kasel too. There's more to sound than dac chips.
EQ fixes NOTHING - only makes things far worse - you want to modify your response by changing your listening environment
i learned nothing. he doesnt make it understandable for beginners. dont waste your time watching. he doesnt show in basic elements with understandable explanantions.
Room correction software is NOT your secret weapon!
Alas, you can’t simply apply digitalroom correction to fix your acoustics.
Room EQ can tame some issues, but it can’t correct for long reverberation times or comb filtering caused by strong early reflections (like those nasty
reflections produced by speaker-boundary interference).
To tame these problems you have two weapons in your arsenal: smart room layout and acoustic treatment.
