We see REW running at the background. Most likely that it's the reason here. Make sure that you close all applications now making use of the microphone as they are holding the state and won't allow access to the mic.

Also, make sure that your Win10 has the microphone security feature turned off as per here:

Do you have any software running (autostart) that might take control of the mic? Like Skype etc.


Not that I'm aware of... the only apps I have opened are DLCT, Microsoft Edge, and Adobe Acrobat but perhaps there is something running in the background I don't know about. Don't have this issue when using the mic with REW,

REW is pinned to the taskbar at the bottom but it is not open (running).
I did check the security feature for the mic and the "Allow apps to access Mic" is on. That was the first thing I checked as that setting is what corrected the mic not working with REW last year after a windows update.


==========================

I'm going to try again today at lunchtime - this time I'll make sure all other apps are closed and I also check task manager to see if there is anything running in the background that may be an issue.

I just noticed my bass management is missing 48db slopes. Is anyone else’s like this. I can’t find anything in manual talking about this.

Thanks in advance

Same here, also DDRC88A is missing those. Then again, I fail to see any use for the bass management with the CDSP. I just tested without it and used routing to mix signals to the Dirac sub channel.

I agree... don't think it is really necessary in our applications... and again just think it is just a carry over from HT where that feature is perhaps sought-after.

The only thing I can think of is when using the Bass Management xover instead of the xover on the sub output tab - There will be no xover filter applied to the sub when doing Dirac measurements as the Dirac test signal entry is post bass management. Perhaps Dirac needs a fullrange signal on the sub to correct for it properly?

Having an issue with DLCT and the mic. The mic is plugged in, the blue led is on, and it's showing up in and is selected under "recording device" - See first attachment

But when I click proceed I get a pop up window that states: "Could not open recording device. Make sure it is not in use by another application." - See second attachment

When I click "ok" that same message box pops up again - then I click "ok" again and it takes me to the next section (Output & Levels). But when I go to adjust levels like stated in the manual - I can't get the blue bars to show up at all... like the mic is not picking up the pink noise.

Any help appreciated.. guess it's not meant to be for me to get this thing working tonight :(


I figured out the solution to this. I noticed that there was no "chime" when I plugged in the UMIK. I had to open windows settings > devices and clicked on the UMIK under the audio section and clicked "remove device". Then I re-plugged the mic in and windows "re-set" it up. No issues after that.... now off to measuring.

Well to get the HPF before Dirac and the LPF before Dirac should allow those filters to be made linear, however , the mic is the where Dirac truly starts , so I don’t see why it wouldn’t do the same to all other channels. It should ,
But the phase shift for sure gets applied to all channels the same when the 1st HPF is done in bass management. So even if it dosent linearize the phase on the crossover , the shift is the same across all channels so you wouldn’t even notice it’s there really except against the sub. And also allows me to have lower crossover on my midrange because that 2nd HPF is missing the bass all together. It’s in one out the other , dosent really matter how it’s done, but I find it useful

But....per the manual , the sub channel has a added 10db , when messing my sub it sure is nice to not loose that in the target. I noticed I get back all my lost sub from cutting target.
And for me with a optical input I don’t have a dedicated sub input. ,

If I remember correctly, Dirac adds that 10dB only when you select 5.1, not in the custom mode. It's not a sub channel's function.
I also use just 2 channels for input. I still would like to have an option for PEQ instead of the Bass management. That would allow tuning without touching the Dirac curve and worrying about if you added too much and Dirac can't compensate and then you have to lower the whole curve etc. Output PEQs after running Dirac should not be touched.

So im having a serious mixer issue that i think might be a bug. Can you verify?

Single pair of rcas into the Dsp.

Left and right midbass on output 1-2
Left and Right midrange on output 3-4
Left and right tweet on output 5-6

This all worked last night and then i opened Dl one time and it all just stopped working.

This is my mixer and routing.

I open up Dl and set it to 6 channels. No matter which of the six channels i choose to run tones thru. It always goes to my left midbass.(did a full uninstall and reinstall and now get no audio out)


If i play music, i can mute individual channels and have each speaker play individually but Dl is now completely dead to me. WTH
Am i missing something?

Okay I’m lost than,


Edit:

In my matrix I have left and right turned on for channels 7&8 so 4 boxes turned on two per channel , that would be a 6db gain overall.
Maybe that’s where my gain is coming from?

But you can right click on matrix and boost into each channel as well on the input

Sub frequency’s I don’t mind turning up a little as long as I’m not boosting, but summing I find ok


I think maybe in the 5.1 you would sum from all the channels ? Each box adds 3db to the signal (if it’s just as strong as signal as the other channel)

For surrounds maybe could boost a little if weak output , but maybe a total of 10db in a surround sum , where I am +6db by having 4 inputs checked on for two outputs


So I’m using bass management in custom

I set my LFE lowpass to 60hz and it sends that to input 7a and 8a , I selected Dirac 7&8 for my bass management channels , and have my sub on channels 7&8, when I add the low pass in LFE I can hear the sub changes, on my matrix I can clearly hear the sub turn on/off , so the signal path is good ,

In DLCT i made custom and set channels 7&8 as “subwoofer “

Run my measurements and , it all seems to be working. I am getting much more gain and the sub seems way sharper when I do it this route

So I’m not sure what I’m missing

Is it just a lowpass before Dirac ?

We could be wrong but I think that you're maybe using an old firmware/plugin for a bug that was solved last week.
a) Please go to your user downloads section,
b) Download the latest version and install it
c) Connect to your unit and click "Restore" - > Upgrade DSP program. It will reflash the DSP binary.

That should do the trick here.

Got my first listen in.

I set it up using separate Dirac channel per driver. I also put in delays on the outputs using the same numbers I used in my previous non DL tune that sounded very good to me. Dirac tab after optimization still show delays though.

Generated driver target curves with Justin Zazzy's spreadsheet using an overall Half-Whitledge Curve. They loaded right up and levels were close enough.... though I think I should of dropped them down more to meet up closer with the bottom of the nulls.

Imaging across the stage was spot on. Need to listen more but definitely heard some details that I hadn't heard before on familiar tracks. Tweeter levels were wayyyy low... not sure why but may be something I did wrong. Need to listen some more and try some different things before I pass judgement.

You should not put those extra output delays if you use Dirac per driver. Only put them if you use one Dirac per multi element active channel.

Where is this spreadsheet available?

Turns out it was the mic not being connected. If you skip past the Mic set up page and just go to test tones. For whatever reason, nothing works the way it should. Outputs come out wrong and matrixing is all over the place..just cuz i skipped past the mic set up.
