I just re-read your set up guide. I will give that a try and let you know. Thanks!

I think the problem is that @Doyanole doesn’t have the .DLL file that is required. I made the old DLCT file available for download, but did not have a copy of the .DLL. If you could make that file available for download, I think that would get him up and running.

Sure, @Doyanole Software folder DL : https://www.dropbox.com/sh/8e4dedm2m...8lvZYMVua?dl=1


This is the entire package and includes readme file instructions & both 32bit, 64 bit miniDSP.dll files.

Nice, thanks. I downloaded it as well in case someone needs help in the future.

You are using a Mac? Strange that you did not reveal that earlier. It makes a lot of difference.

This has me confused. I don't recall any other user who has encountered as many issues as you have, and it makes no sense. The 88A is such a simple device.

Let's re-visit the sub check box issue once again. When you use the latest version of DLCT, connect to the second 88A (which has no sub, if I am correct), and un-check the sub checkbox, can you continue with the calibration? Specifically, can you properly set the level for the speaker connected to channel 3? If yes, and you proceed to outputting the calibration sweeps, is the sweep for channel 3 the same as the other sweeps? If the 88A still thinks channel 3 is a sub, the sweep sounds different for a sub, I believe. If all this seems to be OK, then why can't you successfully complete the calibration? What goes wrong?

I did say it before. I use both , PC and Mac , and i also tried on both . However i did find the lib for the Mac to change it , it's in the readme of mbrown's link. I installed it now . I will try it 2morrow morning.

With my Marantz 8802a the difference between speaker distances could not be more than 20ft. I needed 30ft (because I have 4 subs on a 2x4HD, adding additional delay) between speakers on Dirac 88-a and the height speakers through AVR. I purchased another 88-a and now have 16 channels of Dirac Live (Problem solved )

Thank you both. I'll take a closer look at the levels from all the speakers with and without Dirac on using REW as soon as I get a chance. I was fortunate to have a little more latitude in that setting on the Denon I'm using. I think I'm at 27.3 feet when running through the 88A if I remember right.

I finished setting up my system going through each step of your guide. I also realized I had my new amps at the wrong sensitivity setting. Everything came out just as you described. Negative values on the output tab for all channels but the subs. I had to adjust the level on eac sub because I maxed out at +12. It sounds great.

Question about the crossover settings. At the beginning of your guide you talked about finding the crossover for all the speakers. For my set up it is 90 Hz. Does that value get put into the HPF and LPF filter settings?

I also maxed out at +12 for the sub channel, and had to adjust the levels externally, so we have had a similar experience. The crossover is set for each channel on the LFE Mgt tab. Use the same value for both the HPF and the LPF setting. Except to the LFE channel. In my setup, the AVR provides a 120Hz LPF for LFE, which cannot be defeated. It would be undesirable to have cascading LPF's, so both the LPF and the HPF for the LFE channel on the 88A are in bypass mode.

You wouldn't believe what happened ......




IT WORKS !!!!!

it was indeed the DLL file , or for Mac the dylib file. Changed that , took the old version of DLCT , and baaaam , everything worked. The subwoofer ticker is gone , i can save and load back up , etc....

So i measured both of my Minidsp's as they should , and it sounds' kick ass now ...... really really sweet.....

in case your interested @AustinJerry , here are the REW Measurements of 2 of my curbes i made.

1. is like Dirac measured
2. is Dirac Measurement with a "Fun" DBA Peak and a linear curve on high frequency's (that is really dope)

https://www.dropbox.com/s/qksgsdpp4e...INAL.mdat?dl=0

thanks to all that helped me solve this....

Quick question about licensing again. I purchased a used 88a from a forum member. He purchased it from another forum member here. Neither member ever used the device or registered it. Both exclaimed that since it is not tied to an account I should be able to plug in and go. Issue that I have is #1 is that true and if so how do I get the software. Its not available on my mini-dsp account and I searched the internet trying to find it and can't. I sent an email to mini-dsp but it's the weekend and I probably won't hear back until sometime next week. Wanted to fool around with it this weekend if I could. Any thoughts?

I think you should include the serial number of the unit in your email - I think MiniDSP are only reading and responding to emails/forums once per week - or it feels like that, but their support for issues like this should be quicker.

Do you know if your units need FW updates? If so, you will be best served with dealing with MiniDSP. I think I still have the latest software and prepared to load in Dropbox - but currently running an older version and not next to my PC to check.

Definitely understand. I sent the email to mini-dsp on Friday which was Saturday in Hong Kong. If you don't mind, could you send me a Direct Message with the Dropbox link. I will try it out and if it doesn't work then I will wait to hear back from them. Patience is not my strong suit. Especially after hearing about how awesome Dirac is.

This what you want?

I downloaded it from MiniDSP straight to Dropbox....not my version but should be useful to you. Let me know when you have it so I can delete.....

I would be interested to hear whether you are able to install the software, run a Dirac Live calibration, and save the results to the 88A. Or whether you ran into an obstacle that requires additional support from MiniDSP. Your experiences may allow us to provide guidance to someone in a similar position in the future.

I am in the process now. I downloaded the software. It allowed me to setup and install. I then set up my mic. Just troubleshooting why I keep getting clipping in my measurements even after I properly set my levels. But cant get past the clipping in my measurements. Any help would be great.

You could take a look at the 88a calibration guide linked in my sig to make sure you are doing things correctly.

Just finished my first calibration. Everything loaded and working. I simply downloaded the software from @wl1 and it automatically connected to the 88a. Loaded the calibration to the profile and it works. I also have the Bass Management with the unit. However I have not had a chance to set that up. Will try in a few hours.

I will say that this 88a had 2 owners but neither of them actually hooked it up. So I am assuming that it never was registered to a user, hence no transfer is necessary. I am still wanting mini-dsp to connect this device to my account whenever they reply next week. I never had to login to anything. It just worked. I will keep everyone posted when I hear back from them.

From the 88A User Guide section 3.2: "As of version 1.2.0 of Dirac Live Calibration Tool, license activation is done automatically when DLCT recognizes a valid Dirac Live license code in the hardware unit itself. No separate manual activation step is required."

As you say, you need to make sure your device is registered with MiniDSP. That way you will be able to download future software releases directly from your account.

Edit: What was the issue with clipping?

Simple gain issues on my amps. Got it straightened out pretty quickly with some minor adjustments. Sounds amazing! Can't wait to keep tweaking. Thanks for all of the advice you have given on this device. Your information has been valuable.

I am looking for some ideas on what happened. So my center channel sounds bad and I haven't found a fix for it. Recently to try and resolve this I have moved its location around and taken some REW sweeps on them in full range so that before I do the dirac calibration so I they don't have many obvious issues. I just tested some 5.1 content and the voices sounded like they were whispering and muddled. I had to raise the center channel gain 3db to get them to match up with the rest of the system. I have tested this same content on a friends system who has the exact same amp and speakers and 88a and AVR but his sounds great. Any ideas on what would cause my center to sound so low?

Any chance you played with the wiring and accidentally re-wired it out of phase with your fronts?

That is interesting. I have always said that one of the best results from a Dirac Live calibration is how good the center channel sounds. I listen to a lot of music using Dolby Surround, so my center channel gets a good workout. Have you measured the speaker levels using REW after the calibration has completed? While the levels may not be exactly 75dB, the levels across the front three speakers should be the same. And have you measured the three front speakers by themselves with REW after the calibration? If yes, can you share the measurement results? There must be an explanation.

And you can also use REW to confirm that all three front speakers have the same polarity.

I should have all of those. I will upload them when I get home. And yes the LCR are all perfectly level with each other.

Here is the Left, Right, Center, and L+R rew file: https://drive.google.com/file/d/1kZz...ew?usp=sharing


Here is the DLCT file just in case you wanted that: https://drive.google.com/file/d/15Fo...ew?usp=sharing


If you need anything else let me know.


Thanks

Looking at the Dirac project and applying the Auto Targets, Dirac has no trouble flattening out your four channels. I don't see an issue with the Dirac calibration, although I am not seeing any custom target you may have applied.

The REW measurements show quite a big dip in the 250-300Hz range on both the center and the left channel. I am not sure the dips are bad enough to affect dialog intelligibility. Try switching the audio output to stereo and listen to dialog without the center channel. Does it sound different, or the same? In my system, it is actually hard to distinguish whether dialog is in Dolby Surround or 5.1 (coming from the center channel), or in Stereo (balanced between the left and right channels). This is how it should be, if the center channel is functioning properly.
