Inputs don’t master Its 8ch of Dirac correction and 12 channels of output So yes you’ll have more then plenty of correction You only need 2 Dirac correction channels I would do 4 2 Dirac correction on fronts and sub 2 on rears, and then use the output filters to pre-tune it and get the phase coherent first and then do two channels of direc over everything
It’s a full Dirac 8ch tune Dirac does TA , gains , and eq and phase correction I used 2nd order APF with crossovers off , measured all drivers Made entirety of response the driver can do with crossovers off follow same target, after measurements, turn off all pass filters and turn crossovers on The APF is q.7 AP2 centered at where the crossover will be , that makes Dirac see a crossover and correct the phase shift of the crossover, even tho the crossover isn’t applied yet
@@mountain.audio247 Better in most cases because Dirac can do some time alignment per frequency and remove group delay , where helix can’t But that entirely depends on the system and tuner , no replacement for proper install and placement and execution…. So a helix can be very good , this is probably miles and miles better for a novice tuner with unequal path lengths
@slateraudio hey bro...am havingbhell getting the dirac to (hear) the impulse signal...keeps.saying too much back ground noise ..any help? Can u dona remote tune?
I've always wanted to try active crossovers, is it worth it over using included crossovers (assuming good speakers and crossovers). Seems like the crossover setup with Dirac Live is easy, just wondering if it actually worth getting and fitting another 4 channel amp to run the tweeters.
Not sure what u mean You can use the 8x12DL in a home with a simple 12V wall wart that can do 10A It’s actually really easy and it will be perfectly quiet
Actually no it shouldn’t….. The speakers are to the sides, that’s about 30deg ish that’s mic pointing straight forward , tilting mic up adds a tiny bit more… all the way up is fine also , because in a car , it’s reverbant field is pretty intense, there’s sound coming from all directions , so it doesn’t matter where the mic is pointing and only affects about 1db in the very top octave… In a free filed Situation we know the exact source of the sound so a cal file is important to use the correct one, in a highly reflective field, a cal file of zero or 90 will work with mic pointing about any which way you want in a 180 deg x and y axis pattern…. As Long as mic isn’t pointing to the back window the polar response of the mic is of no concern as well…
As many as you want, if you wanted the dsp to be a sub only dsp , we’ll there’s 12ch and 8ch of Dirac live So 8 sub locations and 12 total amplifier ch
@@BIGBASSSAMA_4 You can use as many as you want, you only can use 8 Dirac ch So that’s 8 locations in the room , tech location you can hook up multiple amps and have as many subs as you can fit and fed off each ch using a pre amp This Unit does 12ch of audio , that’s 12 rca jacks into amps , and 8ch Dirac ch You can split the ch and add more , make since It’s over kill tho and I don’t recommend it but , you can
Why wouldn't you sit in the driver's seat, or have someone else sit there, while you run the setup? A body in the seat will play a big role in absorption and reflections, ultimately changing what the tuning software should be doing in relation to amplitude and EQ.
The 1st preset was all in driver seat This customer wanted a passenger side tune , (I think he makes his wife drive on long trips) Also , the Dirac tune yet is good , isn’t anywhere near as good as a mult mic array in smaart. But still pretty good. Its phase correction works nice tho. I noticed almost no difference weather tuning in or out of the car, in some ways its better out because the body isn’t blocking reflections that otherwise needed to be in the measurements. Apples to apples , I heard no difference weather in or out of car, and that’s with a few hundred different cars I’ve done with Dirac
@@slateraudio Thanks bro. If I get the one with DL, and one day I decide to manually tune the system (without Dirac), will I be able to do that? Asking because I'm still not sure of how the whole workflow works.
@@slateraudio Bro, it's me again. I've been considering your advice, and been finding non-DSP amplifier solutions to pair it with C-DSP 8x12 DL is very challenging. 1. I need 12 or at least 10 channels amplified, so that's either 2 units of 6 channel amp, or 6+4 channels, or 4+4+2. It either gets expensive, or take a lot of space. 2. Using TPA3255 boards meant for home theater call for the use of bulky 12v to 36v DC boost converter. And the cost of 2 pieces of 6xTPA3255 boards + 2 boost converter is not cheap either. Plus it doesn't have all the noise and clipping protections. So I'm wondering what do you mean by the "low level conversion is goofy" for the Harmony one? The harmony unit only takes USB input and also SPDIF. There's no low-level input. Are you talking about the low-level output?
Great video for those of us learning to use DL. Thanks for creating and posting it.
i wish more ppl covered automotive dirac, do you know if its any different than like DIRAC for home theater processors / avrs?
It’s the same exact version as a home avr …. It works decent in a car
I want to use this DSP for 3 way active, 2 rear fill and 1 sub. Will it be able to do that? If I understand correctly it only allows 8 input channels
Inputs don’t master
Its 8ch of Dirac correction and 12 channels of output
So yes you’ll have more then plenty of correction
You only need 2 Dirac correction channels
I would do 4
2 Dirac correction on fronts and sub
2 on rears, and then use the output filters to pre-tune it and get the phase coherent first and then do two channels of direc over everything
Very cool, did you pre enter measurements for time alignment to the mic?, or was compete DL tune?
It’s a full Dirac 8ch tune
Dirac does TA , gains , and eq and phase correction
I used 2nd order APF with crossovers off , measured all drivers
Made entirety of response the driver can do with crossovers off follow same target, after measurements, turn off all pass filters and turn crossovers on

@@slateraudio can't wait to get my cdsp 8/12 in and tuned
@@slateraudio how would you rate the overall sound quality compared to let's say a helix or any others along those lines?
@@mountain.audio247
Better in most cases because Dirac can do some time alignment per frequency and remove group delay , where helix can’t
But that entirely depends on the system and tuner , no replacement for proper install and placement and execution…. So a helix can be very good , this is probably miles and miles better for a novice tuner with unequal path lengths

great video! where did you get the mic stand from? did u buy the DL version of the DSP or did you upgrade a non-DL version? can't get mine to upgrade.
It’s a customer car , it’s DL.

Yeah Dirac does a fine job at summing crossovers… yes it’s very good
Wonder there be any hum if I use from oc to avr. The cheapest way to do 5.1 audio.
Not sure what u mean

Hi what’s the cheapest pre amp with 6 channel in and out via rca or amp with sub out. Thank you sir.
The mic should be pointing directly up.
Actually no it shouldn’t…..
The speakers are to the sides, that’s about 30deg ish that’s mic pointing straight forward , tilting mic up adds a tiny bit more… all the way up is fine also , because in a car , it’s reverbant field is pretty intense, there’s sound coming from all directions , so it doesn’t matter where the mic is pointing and only affects about 1db in the very top octave…
In a free filed Situation we know the exact source of the sound so a cal file is important to use the correct one, in a highly reflective field, a cal file of zero or 90 will work with mic pointing about any which way you want in a 180 deg x and y axis pattern…. As Long as mic isn’t pointing to the back window the polar response of the mic is of no concern as well…
Where can I get the program? Could you send it to me?

How many hometheater subwoofers can I connect I have 9 small subs lying around my house I'm a sub collector

You can use as many as you want, you only can use 8 Dirac ch
So that’s 8 locations in the room , tech location you can hook up multiple amps and have as many subs as you can fit and fed off each ch using a pre amp
This Unit does 12ch of audio , that’s 12 rca jacks into amps , and 8ch Dirac ch
You can split the ch and add more , make since
It’s over kill tho and I don’t recommend it but , you can

A. C-DSP 8x12 V2 (No Dirac Live)

Don’t get the harmony
The low level conversion is goofy

WTF is all the noise ....
so many things wrong with this video I don't know where to start
That it’s not complete ?
There nothing wrong with it , the car won in comps …
It keeps the minimum phase in the crossover, it works tremendously good
