Obsessive Compulsive Audiophile "OCA" Corrections - Categorization Tools Assistance

There's no eq beyond 200Hz and there's no boost in eq with default AcoustiX settings. Make sure you are not using the system in Audyssey Reference mode which has boosted filters for low volume listening.

Thanks for the reply. I checked and it was not in reference mode.
It was however in flat, but turning that off didn't chance anything.
In the past I remember the Restorer setting doing similar funny things, but that is turned off as well.

If there is no EQ beyond 200hz I wonder where the issue suddenly came from, because aside from the subwoofer nothing in the system changed. Neither did any of the denon settings.

This sounds like the filters were never transferred to your AVR. Audyssey Flat vs Audyssey off would have made a very audible difference otherwise. Seemingly successful transfers silently failing is not uncommon with A1, I'd suggest to repeat the transfer process of the optimized ".oca" file to your receiver.

Much appreciated for the quick feedback, I will give this a try later.

Need some help. I've completed the A1 Acoustix calibration with the OCA script last night. I have a AVR-x4800H running in 5.1ch/Zone 2/3 configuration with the Surround channels turned off in the web control for a 3.1 setup. I've previously run Audyssey and also completed the manual configuration process using OCA's video using Multi-Eq android app to load to the receiver. OCA reported the Amp Assignment as FL, C, FR and SWMIX1 which is correct

I ran the A1 Acoustix using 1 position (MLP) and 8 sweeps to create the OCA file for loading. This all worked after loading to Speaker Preset 2

Yesterday I completed a 3 position around MLP and 8 sweeps to create a new OCA but I can't get this file to load as the Acoustix script is complaining about Amp Assignment. I've made no changes to Amp Assignment - I'm still running a selected 5.1ch/Zone 2/3 setup as the first load. I've tried turning on/off the Zone 2 and Zone 3 loading in each configuration (i.e. 4 times) and still get the same error message. I've also tried loading to Preset 1 again with the same error message.

I was going to try and just retake all the measurements after doing an AVR settings in the Acoustix main menu but now I've got the dreaded "Audyssey mic failure"occurring with SW volume reporting below level and FL speaker not found. Tried to rerun an Audyssey calibration using the Receiver and Multi-EQ app but get the same results. Looks like the Audyssey mic has failed.

Does someone know what the OCA script is looking for in the "1" vs "0" of the error message. So I can make the receiver go to this configuration and load the Acoustix calibration run I just completed. I need to sort out the Audyssey mic issue with Denon as this is a new receiver from them directly via Amazon fullfilment.

On an alternative note - If someone can outline what the A1 Acoustix script expects to have completed in REW set of waveforms processed manually. I can retake my measurements using my miniDSP UMIK-1 and REW to have measurements created for and Acoustix processing via the main menu. But I don't want to do all that processing and end up with the same Amp Assign error.

If I remember correctly OCA mentioned in the video for acoustix to not use the web-ui for settings as it can cause issue.

Why don't you run the optimization with all speakers? In the end might as well use the few minutes extra to have those run through the calibration.

Amp assign info reported by your AVR at the time of transfer is different to the one reported at the time of initial configuration (and saved to receiver_config.avr file). If you have checked and confirmed every setting in Amp Assign and Speaker config are identical, then there are some other possibilities (yet to be confirmed) including preset number going into that info string. or directional vs standard bass mode difference. If you generate a new config file and repeat optimization with the same ady file, then it should go through. You can also edit the string in the .oca file if you don't mind where that difference is coming from.

A new Audyssey mic failing so quickly is quite rare but not impossible. You can use Umik and REW and use rew_averager tool (you can find in the video download folder) but that code is not 100% optimal at the moment.

There are quite a few Denon users out there reporting the Audyssey mics failing some within short ownership timeframe's and other's longer. I believe the Audyssey mics may be ESD sensitive. In the US Northeast right now we get a lot of static discharge and I wasn't particularly careful about grounding myself to the AVR-x4800H unit before bringing the mic plug to the receiver. Could have generated a spark that killed it.

I'm quite comfortable editing files as long as I know the form it needs to be in for editing vs output format (i.e. txt, xml or something else). I haven't tried to look at the OCA file in a native format.

On this latest with Acoustix I wanted to get the 3 mic positions recorded with 8 sweeps and incorporate Carl's (HD MOVIE SOURCE) method for the post 500Hz section into the calibration file. That all went well during the run so I was looking forward to the resulting measurement.

I think I can do the required Averaging as long as I know the parameters and expected waveforms that need to be resident in REW to finish running the Acoustix script. I've copied a not so little crib notes version of OCA's walkthrough in the original 3 year ago method for manually processing the waveforms with dspMINI UMIK-1. If someone wants to coach me on where to stop and/or modify the output file required to complete an Acoustix run.

 

[cruisinforgold]

I was finally able to edit the OCA file from my PEQ filter run based on Carl's added method and get the OCA file to load in the receiver.

Thank's OCA for that hint to edit the outgoing file.

Now for the listening part and eventually I need a new Audyssey mic.

But I would like to tackle this with a dspMINI UMIK-1 as I believe the beyond 4kHz region is not well represented by the Audyssey mic measurements. Just an guestimate with no data to back it up.

Good to hear that. FYI all these files (.avr, .ady. .oca) are json files and you can edit them in any online json editor.

They are really cheap build quality mikes but I've got 3 here that still work without issue, but I do try not to knock them around too hard.

A1 Evo AcoustiX can now use custom calibration files with the ACM1-X mics (MultEQ-X). Details in the YT video description.

 

[Fahzz]

But you still need to pay for Audyssey MultEQ - X to use the ACM1-X microphone, correct?

You need MultEQ-X app to download a calibration file for the serial number of your mic. I am not sure if you need to pay for the app to do that or if even trial version can do. It's also unknown if the paid version still does that since Audyssey seems to have abandoned the app for sometime now. Asking someone with the paid app to do that for your mic serial number is also an option.
