This is from the Emotiva Dirac Manual. Does it still apply? If so, this would preclude the possibility of using one set of measurements for both speaker presets and then turning off a center channel or subwoofer in one of the presets. Correct? WHEN YOU CHOOSE TO USE A DIRAC FILTER SET IN ONE OF THE SPEAKER PRESETS IT IS VERY IMPORTANT THAT THE CONFIGURATION YOU HAVE SET IN THE SPEAKER PRESET MATCH THE CONFIGURATION THAT WAS USED TO CREATE THAT DIRAC CORRECTION FILTER SET. Failure to do so may result in some speaker sets failing to play entirely or playing with incorrect correction filters applied to them. You may change speakers from Small to Large, or from Large to Small, but you should not add or remove speakers from the configuration. Let me address this with a twist to what geebo and marcl said. If the Speaker Config has changed, ie you deleted or added a speaker, AND you want to edit the Dirac Filter again later, this will fail in Dirac. But, any speaker in a Filter that Dirac calibrated can be set to None and all the other speakers will get the calibration assigned to them. So you can turn them on or off as you wish, but only those speakers in the filter get the calibration that was assigned to them when Dirac created the filter.

That is how I understood it to work but after remembering that portion of the manual I was unsure. The reason I brought it up was that I have preset 1 set up for 7.1.2 and preset 2 set for 6.1.2 with no center channel. I measure and calculate filters in Dirac in 7.1.2 mode and then just turn off the center channel in preset 2. Yesterday I had some strange sounds coming out of the center channel when in 7.1.2 mode. I was wondering if that was the issue but it seemed unlikely. I would expect problems in the 6.1.2 preset if this was an issue.

I too have tried to turn off the center channel, assuming that Center=None would force a downmix of center to L/R. I found that sound still came from the center channel. If I recall this could be related to another issue that has been reported where Dolby Surround Upmixer does not work with sample rates greater than 48KHz. I don't think this issue is related to Dirac at all. I'll do another test to confirm.

It fails at the end of loading a project, without doing anything else to trigger it. I haven't tried making new measurements, I must wait until my neighbours (apartment) go out, because of the noise. No microphone attached. /b What is the size of the file you're loading? If it's 7k, or actually anything less than 50k, it's probably corrupt and all you need to do is make new measurements and save a file successfully. It's 159,548 kb, and successfully loaded in the previous version of Dirac. The backup project file also fails. /b

You may change speakers from Small to Large, or from Large to Small, but you should not add or remove speakers from the configuration. Removing speakers should never be an issue. Dirac does its magic on each speaker without knowing about the others. However adding is not such a good idea. It will make the added speaker play without Dirac filter. It could sound really strange. But nothing will break though..

I was wondering if that was the issue but it seemed unlikely. I would expect problems in the 6.1.2 preset if this was an issue. Yesterday I confirmed that you can set Center=None with either User or Dirac Equalization Slot and the result is the same. However ... setting Center=None does not always work as you would expect. With Multichannel content that has a high sample rate (>48KHz) the center channel will play whether it's set to None, Small, or Large. If the sample rate is 48KHz or less (i.e. for Dolby 5.1 content or multichannel PCM) the center channel will NOT play if Center=None ...... BUT, I have not confirmed that it is downmixed to the L/R as we would expect. With 2-channel source upmixed with DSU or DTS:X, if Center=None the center will not play. I can't think of a way to confirm if any content is lost in the upmix with the center channel disabled.

I can confirm this marci. The center channel does play when set to none with a sample rate >48hz and it is a multichannel source. This happens regardless of what up mixer is used. Same results with Dolby and DTS and Direct. I know you have reported this before. Does Emotiva know about it?

But as with my report several months ago of upmixing not working at all with multichannel sources with sample rates >48KHz, it may take a long time to acknowledge and total crap shoot on whether it will ever be fixed.

Hey guys, i need some help. I have the latest Dirac installed and when i go to the volume calibration page and click on any speaker, i get no sound. Even if i raise the master volume all the way..any ideas?

Even if i raise the master volume all the way..any ideas? Which type of computer are you using, PC or Mac? If Mac, I initially had trouble with the microphone when I moved the mic slider within the Volume Calibration screen. So I discovered a work-around. After starting Dirac and going into the Vol Cal screen, I'd go immediately to System Preferences and adjust the microphone from zero, yes Dirac set it to zero, and moved it to 100%, then go back to Dirac and DON'T TOUCH THE MIC SLIDER. This allowed me to get through the calibrations using all the other sliders, just not the mic slider. Dirac has some work to do on this latest and greatest.

I'm using a pc, but i don't have a problem with the mic. It's picking up sounds in my room, but when i press play to any speaker, the speaker level meter goes up and down in sync with the mic.

Strange thing is i got the 1st speaker to make sound and then i got up to do something for a minute, and now i get no sound again.

Which firmware version on the processor?

Did the version previous to Dirac 3.0.11 work ok? Which firmware version on the processor? After 3 and a half hours of messing with it, i finally got it to work. I had to do a hard reset and unplug it from the wall. It was worth the trouble though, because after listening to music and movies with Dirac it sounds incredible. I did just get a new JTR captivator RS1, and listening to my favorite demo scenes i kept saying this is insane over and over. I listened to the same scenes right before Dirac engaged, and it was day and night difference.

Hi. I just got my XMC-2 a week ago. I have questions about dirac live. After I ran dirac live, is there anyway to see about what dirac live live did, for example distance of the speakers, level and crossover. Cause I checked levels, distance all is at default value. Also is there any neccesary steps to take before running dirac live, for example set the crossover etc. thanks.

Thanks for the info. I have another questions. I have 2 subwoofer connected to center sub using minidsp. I ran dirac with left/right sub set to none. When I am done with dirac live, the only way to change center sub to lfe is by turning on left/right sub to mono or dual mono (even there is no sub connected to this output) My questions is for dolby atmos movie, does it make any sound difference running center sub LFE (with left/right sub set to mono or dual mono). Or running center sub MONO (with left/right sub set to none)?

Or running center sub MONO (with left/right sub set to none)? LFE is the .1 channel and has no bass management. Bass Management is sent to any subwoofer channel set to Mono. If the Left/Right Subs is set to Mono or Dual Mono, and the Center Sub channel is set to None, then Bass Management AND LFE is sent to Left/Right Subs. If Left/Right Subs is set to Mono or Dual Mono, and the Center Sub is set to LFE, then Bass Management is sent only to Left/Right Subs and ONLY LFE IS SENT TO CENTER SUB. If Center Sub is set to LFE and Left/Right Subs is set to Mono or Dual Mono but there is no subwoofer connected to Left/Right Subs, then the bass meant for any Small speaker will not be heard. Only LFE, the .1 Low Frequency Effects sound will be heard in the Center Sub. If Center Sub is set to Mono, the Bass Management and LFE will be sent to the Center Sub. edit: My system is set for Bass Management going to Left/Right Subs set to Dual Mono with subwoofers connected to the Left and Right sub outputs, and Center Sub is set to LFE with subwoofers connected to the Center sub output. The overall sound is better when LFE is sent to dedicated subwoofers and Bass Management goes to different subwoofers.
