DIRAC LIVE Room Correction GUIDE | Taking MEASUREMENTS, adding a HOUSE CURVE (PART 2 of 2)

In this video, I'll show you how to set up the volume within the Dirac Live app to take proper measurements (without clipping), some tips and tricks for taking measurements to ensure you get the best results and some notes on applying a house curve to your subwoofer and speakers. Huge thanks to Dirac for gifting me software licenses and a measurement microphone in order to make the review video and these tutorials!

The best series of setting up and running Dirac. Thanks so much

[arielrodriguez]

When you say that frequencies below 100hz requires all speakers to be set the same, below 100hz that would be like 60, 50, 40 etc if I boost or lower them correct?

In order for me to install my Dirac room correction, I have to run an Ethernet cable from my router to my Home Theater Processor. After I have installed my room correction and the Hartman curves, once I disconnect the Ethernet cable, will the Dirac Process still be able to change curves in real time?

[Wrecked]

Great video. How do I go back and adjust each saved curve? Thanks!

[forrestwagg]

Finally a simpler explanation! Thank you. I have an Onkyo TX-RZ50 This DIRAC setup doesn't seem to detect my subwoofer. It's delay is 0.0 ms. (like its right next to me) or it thinks its 30 feet away. Its 15 ft. Any suggestions?

A couple of questions.Those Haman Curves from Youthman, do they only effect bass? Don't the typical Curves reduce treble by more?
Could I add my own PEQ from REW, and add to the curve screen instead of using Diracs measurement?
Can I only cut and not boost using Dirac like REW? So, can I adjust the volume of the target curve?
Can I only measure one position?

Thanks.

I have two filters saved for my Integra DRX-3.4 but I can’t find them in the integra setup menu to select. How do you find these filters on the receiver?

I just got dirac live on my Marantz AV10. My issue that no matter what I do it's set the subwoofer trim on the AV10 in the positive...the lowest I can get it to go is +5 and +6 on by subs. I have 2 SVS PB4000s, so the subs aren't the problem. I've always heard that you want a negative trim on the subs. When Audyssey set it it was -2 and -4. Any pointers on how I can get the trim down?

Just purchased Onkyo receiver tx rz 50 and I'm setting up Diract first time and I really like where you demonstrate the actual mic placement.

Umik1 w/90 calibration + RZ50 + klipsch R115SW subwoofer: Everytime I try to calibrate, it sets my sub DB to -13ish. With that config, while watching a movie, the sub doesnt even turn on (its so low). I set it the same as the other speakers during volume calib. I figured maybe it finds it too loud while doing the tests, so I clear the points, set the sub 10DB lower volume in the volume calib, try again... same result. Ive found tons of comments with people having same issue, but have not found a solution. Any ideas?

[shanewilliams]

I want to start off by saying thank you for making such easy and simple videos to follow along with! Huge Help. However, I'm still stuck/lost on the following process. I have the Onkyo RZ50, Def Tech BP9060 set up (built in subs) and a third M&K Sub behind my theater seats. And, the RZ50 has diraclive built it, which I've use and it's working. I want to use the mini dsp 2X4 HD to set the subs up correctly/better. But, after I get the subs all set how I need them, when I run diractlive after, how do I make diraclive not mess with the sub set up, or am I making this to complicated!? :)!! Any input will be helpful. I'm certainly a novice at this, but I do want things to be correct in my theater room... Thank you again!

Should you calibrate your subwoofer with the included microphone before you start Dirac live calibration?

On my Velodyn SPL-1200 (old model) I have a included microphone and remote. In the instructions Ther is something about phase. Should you do that before you calibrate?

[sierranuestra]

Great Brad, its the video I always was looking for.
How do I set the LFE channel? I own an ARCAM avr and doesnt have the LFE option on the menu. Should I set it manually on my subwoofers the crossover to 120hz?

[eduard_spb]

Hello! I bought a UMIK 2 microphone and I have a very short cable (2 meters) in my kit. I see you have a cool long USB cable in your video. What is the brand and model of the cable you are using? And tell me if a long cable does not distort the measurement?

[keithiegee]

Great video. If you don’t have the head room to apply the house curve do you increase the volume on the individual speaker or Subwoofer at the very first menu? If so do you then have to go back and re-measure?

[photominion]

So, that Harman 10dB house curve... It only affects the bass?
Because most users prefer to only use Dirac up to maybe 600 Hz?
I kinda like the Dirac default setting with +5.3dB bass shelf and -3.2 dB treble roll-off.

But I'll have to measure again. I have the LFE gain at 9 o'clock so the auto-switch gets triggered sooner. With that, the sub is barely audible in Dirac. But I missed the part where you can just lower the volume of all channels and keep LFE at 0.00 so that a higher master volume would raise it enough to register.
(e.g. lower the speakers all by -8dB roughly and leave the sub at 0 so they play the same SPL?)

[BhavikPatelhr]

How do you connect Denon with Dirac. Means use of Dirac for denon avr. Older model are not supported with Dirac.????

[DesireU]

Question: If you’ve run Dirac already, but you later decide to change the subwoofer’s crossover, do you need to run Dirac again? Please help!

[shanenewton]

Hi just trying out dirac, trying to load the house curve that you show but having trouble loading it
When I go into dirac menu it is not showing the Harmon curves
Any advise would be appreciated

[jacobwiqvist]

What volym should you have on the receiver when starting to calibrate?
