Got 8ch to work

Get the levels too low message before it would even take that measurement, something seemed weird .....but let’s wait. I’m going to do my gains the right way tomorrow. I know there a mess right now I can hear it and see it.


OTOH , oh my !!!!!! A entire new level of clarity
It’s unbelievably amazing. Much better than a plethora of devices.... and this is the first go round and it’s amazing.

There’s definitely something special about this Unit. I’ve been diracing for a minute and this is entirely different. Like , way way way to the extreme on point and very good.

(I should’ve bought a 88BM Year’s ago! )
But this is better!

Wow :kiss: :woohoo:


Super to hear this feedback. :-)

For the low level error, please send us more info (Screenshots of your measurements along with Dirac live projects), we will feed it back to Dirac team so they can review it. Something is to be investigated so we can remove that little annoying pop up. :-)

About that level too low message: what Windows are you using? I'm using Win 7 Pro 32bit.
I'm going to do more Dirac measurements later today and put levels almost to the max just to see if the low message still appears and also if there is any audio signal output before the message.

Ok, make sure it's not too loud though... :laugh: please send us some feedback on the RMS meter reading you're seeing when you're doing a test tone on the OUTPUTS&LEVELS page. Take some screenshots of the measurement level and also share your project so we can see what's the measurement like.

Just did a short Dirac test, will send full info to Support soon.
I set levels on all channels between -12 and -6. Started the test and there was no sound before the low level error appears, I think I heard only a small click. Maybe a firmware bug, its not enabling outputs at this stage?

And plugin's subwoofer level display still doesn't work correctly. Now it seems to jump to 8dB after adjusting...

Dear All,

Thanks for the feedback! As mentioned separately separately to some of you, this is officially a bug! :-)
It's been looked at by our team and Dirac for the past 2days and we'll report asap we have more information. We didn't see this error before as we were using a modified DDRC-88A Dirac Live build so it could work with the 8x12. Something in this new multichannel build isn't right..

Stay tuned for an update and thanks for your patience. In the mean time, it's just a couple of clicks only to be done during the measurements.. As some of your may (or may not know), you actually don't need to redo the measurement all the times.. Simply save your project. You can edit that target curve however many times you want and reload the DSP settings. Typically, one do measurement few times till he gets some right measurements but after that, unless you're messing with the routing/crossovers of your DSP, you shouldn't need to perform measurements for "tuning" your target curve... Most of you might know but I just wanted to clarify few newbies who are not all familiar with Dirac. :-)

And also notice that you can do the editing without the c-dsp or mic connected. So do the measurements, save the project, go inside and use a proper mouse&monitor and edit/save few projects with different curves to test out.

Exactly what I do on hot days, take it inside, spent some time working on projects and then just sync it to the DSP when back in the car.

It actually works, you have to do a firmware upgrade with the sdcard, not a DSP upgrade via the plugin.

But the way it works is a little confusing. It effects to the output level (of selected channel/s) exactly at the same place as the output sliders. But adjusting via the subwoofer setting is "hidden" i.e. not shown in the output level settings. So you could have there channel output set to +12dB and still have adjusted the same channel to -20dB via the subwoofer function.

Got a new tune set up to a curve I like, the stage is absolutely amazing. @devteam you guys have knocked it out of the park, it is so so good. My center is high and nailed to the center of the dash, the stage width makes it seem as though I have no sides to the car, I have no clue how it works but it is incredible.

But.... (always a but).... I might have discovered another bug sadly. I loaded a Dirac project to preset 3 that uses 7 of the 8 channels. It works nicely, sounds great. If I then move to say preset 1 and then back to 3, it's like Dirac suddenly cuts the output of my mids / mid-bass and sub, but leaves the rears and tweeters the same. If I delete the preset and reload it, then its good, but as soon as I move to another preset and back to 3, its gone again.

I am not sure if somehow it is getting confused as on Preset 1 and 2 I am using 5 channels, and on 3 I am using 7. I'm going to email support and see if there is a way to log the behaviour though as it's odd.

Great Feedback! So on this tune - You used a Dirac channel for each driver?... How does it compare to using a Dirac channel for each set of speakers?

Almost, I used:
Dirac 1 - L Tweeter
Dirac 2 - R Tweeter
Dirac 3 - LMid and LMidBass
Dirac 4 - RMid and RMidBass
Dirac 5 - LRear
Dirac 6 - RRear
Dirac 7 - Sub

I have only listened for a few minutes with the 7 vs 5, so take it with a grain of salt, in addition microphone positions may have been different between them. I also can't switch from one to the other due to the problem I described above, but, based on the quick listen the 7 is a definite improvement vs using sets of speakers. I think with the distance to the tweeters being much closer than my mids/mid-bass it just allows the Dirac to set the delays more accurately. If you were closer I'd say come get a demo, but a 12 hour round trip is obviously not feasible. It's kind of tough to really describe how it sounds, IIRC at the NC meet last month you said my tune was the best it has been, this is much much better.

No need.... Your review here is the straw that broke the camels back - Pulled the Trigger on it :woohoo:

Will hear it for myself this weekend :)

With 5ch Dirac have you adjusted each front channel element's delays before running Dirac?

How are you making the measurements, do you sit inside and hold the mic? Do you point the mic up or forward?

Nice. I will be looking forward to your thoughts on it, pretty sure you will be pleased.

I did not adjust any delays beforehand, so far have not felt the need to do so, it does it all just fine. I am sitting inside the car, at the moment all my measurements have been with the mic pointing up, I may try in the coming days with it pointed forward.

But Dirac can't (or can it?) adjust the time difference between each element of a 3-way channel. That is, unless you use more Dirac channels.

I'm just thinking maybe that is the reason why 7 channel sounded better and with correct delay adjustments 5 ch would be as good. Who knows.. I'm definately going to try with 7 Dirac channels.

That's what I don't understand, how does it measure the delay on grouped sets of speakers, even using 7 Dirac channels, I still have 2 channels that are in a group (midrange & midbass).

I may try some experiments with the 5 channel and adding pre-delay to the speakers in a group, but in all honesty once I get the 7 channel dialed in fully I don't know that I will bother with a 5 channel again. Will likely just end up with 2 presets saved, possibly 3.... one for daily driving, one for competition and one to show the difference with rear fill on vs off.
