Audyssey One - Nexus (Automated hi-res Denon/Marantz calibration with REW/Umik-1/2)

You only need to repeat the transfer, sometimes filters seem to transfer fine but they don't. There are no known issues with x3800 though.
 
@OCA Question for you, while we have your attention. I've been very happily running with A1 Evo Maestro MJ for a while now, which set my mains to full range with LFE+Main. I really found this to be a big step up in bass performance and have stuck with it ever since.

But I've noticed that somewhere along the way you've dropped this as an option. Not having followed all of your more recent versions, do you mind telling us why you've made this decision?
 
I wanted to master crossover algorithms which I have now completed. I will add LFE + Main option to Acoustica at some point. But I can assure you Acoustica will beat MJ LFE + Main calibration easily in clarity and probably also in bass.

Update: Did a quick new 8 point measurement set using audyssey mic + neuron's measurement tool, ran a new optimisation with acoustica, and all speaker polarities were good and it correctly transferred the crossovers to the AVR.
Only thing still not working for me is the auto launch of REW, I do get a message stating that REW seems open (even though it's not), yet without the API server started. It was already happening on first test, though an easy one to get around by manually opening REW and starting the server.
Will give it a test now ;-) Thanks again
 
Rew can install itself to different places in different operating systems, with every update compatibility will increase though. Someone added a lot of new Mac paths this morning in github.

Hi. V2.5 is setting negative distances... Is this a bug or a new hack?

One minor bug left in v2.7:

sub inverted? returns a numerical value istead og true/false


Also, when the scripts reports the dip revoval efficiency, it always skips the front channels starting from SLA/SRA. It was like this since Neuron v1

Edit: I'm just gonna try the short ports right now since it's the only real practical mehtod right now. I'll report back in a follow up post about the new results! Also: Please bring back the performance table. I really liked that.

Edit2: Nope, Long Port it is. Short port also settled for 40 Hz, but sounds a bit muddy overall now. Probably because my uncalibrated 43 Hz peak is even worse with short ports and the port phase shift happens a few notes higher.

Hi @OCA !

I am wondering lately: In every case, my optimization results 40 Hz crossovers. Even with stock Audyssey and listening tests before using A1 it appeared that this is actually the best crossover for my system. Of course, 3.1 (still currentlly using that, will try Acoustica later) makes a day and night difference compared to stock Audyssey already, but I'd like for my system so use 60 Hz instead of 40 Hz since 40 Hz is already pretty low for my Reference 3 Metas and I'd like to "free" them a little more.

Now I have three options:
a) Just pick 60 Hz als lowest crossover search -> did that, 60 Hz actually has a low performance score of 73 % if I remember. 40 Hz has 82 %.
b) Use the Short Port plugs for the KEF Reference 3 Meta on the ports to make the rolloff in the bass harder and keep the speaker more linear up until 43 Hz. The long ports provide a longer roll off with the tradeoff of a little less bass strenght overall. I am currently using the latter.
c) Use port plugs to turn those speakers in into closed ones. I would sacrifice a lot of bass performance, but maybe it's actually a good thing for phase/subwoofer integration?

What would you recommend? What would you personally use?
Thanks in advance for your answer!

I always get 40Hz for my fronts, too because they are quite large full range-ish towers. You could get 40Hz even with smaller speakers if they are too close to walls. The algo optimizes maximum energy with 2 fronts and all subs combined and is unique. I wouldn;t recommend capping fronts, all other speakers are suitable to play with XO caps but not fronts.

So how is that going? intuitively does not seem right though. Also any attempts to add LFE distribution to the equation?

Unfortunately no progress in that front yet because I am still dealing with compatibility issues of the filter transfer function with some lower models. Do you use LFE distribution? I have an old 6011 which doesn't have that (has a hidden bass extraction frequency and directional bass mode) and haven't heard many people use it so little info about it.

Also, multiple mic position measurements may change the selected crossovers one notch up or down depending on the pattern.
 
Hello All,

Im new in the world of optimizing my Marantz with REW, UMIK and NEXUS. I've whatched multiple video's of OCA before starting, thanks for your nice work!
I've done multiple measurements with my Umik-1 in REW ending up with 6 measurements that i want to use in Nexus.

When using the scripts it keeps telling me that the target curve needs to be selected in -> REW/EQ/House curve, however i've selected the house curve, tried different curves all with no succes.
I've reinstalled REW, latest BETA. That also didn't help.
In Part 2 of OCA's nexus video he also forgots to select the target curve, so he ended up with the same error. But after selecting the right "house curve" he reloads the script and succesfully moves on with the proces.

Is there someone that can tell me what i'm doing wrong?

My Marantz is now at factory settings, so it doesn't sound quite good at the moment

REW changed house curve API endpoint in the latest beta 78 and Nexus will not work with it. Use Acoustica which can also work with manual REW measurements.

Yes, use both LFE+Main and LFE distribution. Have pretty big bed channel speakers and bunch of amps, so works well.

Thanks for the quick response! Acoustica was the solution, i was able to run the script. What a difference so far! The only thing i see is that all my speakers are set to large in my Marantz. I thought i read somewhere that the script sets them to small? Do you have any idea what is happening?

Upload it to the avr again. My x3800h didn't take the XO settings the first time.
