To me that's 1 thing that differentiates ARC from all but the most expensive full-blown RC systems like Trinnov or Lake.
Yeah, my room looks like a space station. But that's another (long) story, and it is a FACT that below 100 Hz or so, no reasonable acoustic treatment can do as much as needs be done. Like many others, I find it best to do as much as feasible with acoustics, the rest with DSP.

Regarding Trinnov, I considered the Amethyst, maybe used as it would be a big stretch for me. But being (basically) built on a computer chassis, it has a fan; and at least one reviewer found that fan audible. That crossed it off my list right away. I think I'm happier with ARC, with fewer knobs to twist. I actually do like music as well as fiddling with the hifi.

Cheers!

Everyone's situation is different right?
I have a dedicated music theater room built from the ground up in my basement.
In there everything goes as far as what I want to do tooptimize the A/V experience for home theater & multi-channel music.

In the living room I have to take into account the asthetic opinion of myself and others.
Since it is 2-channel, it won't be extreme and I don't think it needs to be that way.
No coffee table or glass furniture. Vicoustic makes attractive, effective treatments but measurements will taken after everything is configured.
The treatment decisions will be made then.
I like as clean a living space as possible while still being comfortable, inviting and not sterile.

Cheers to you too!

Correcting above 500hz doesn't automatically involve the speakers themselves but the room and to an extent placement, right?

That's exactly why it's problematic, i.e. trying to correct the effects of boundary reflections and comb filtering, which vary wildly with location.

I don't know why more RC systems don't do what my lowly HK 635 receiver did - take a measurement directly in front of a main speaker to capture its intrinsic response.

The STR is in a different class to my ears, in that I do not notice any adverse effects from its DSP.
If that's true for STR, then the ARC implementation on STR is much better than on MRX/AVM.
I would really like to hear STR.

Doesn't a system that measures at multiple points (like ARC) address that issue, at least to some degree?

Yes, but the resulting averaging may not be better than nothing.

Granted; that's always a possibility. In my experience, it has been a lot better than nothing. Perhaps that's because the rooms have been treated acoustically.

Question

Has anyone here had the opportunity to try ARC Genesis? I've been hoping for it, but the Web site still says "Coming Soon -- Available April 2019."

(I suppose I shouldn't be surprised, as in my experience, audio companies are always late with hardware and later still with software.)

If you have tried it, comments on how it differs, please?

Well AVM-60 owners likes myself are having issues with Genesis....Surprise:

https://www.avsforum.com/forum/90-re...hread-297.html

I gave up on my Windows 7 Premium laptop (Acer Atom), yes it's old by todays standards so I purchased a new HP laptop running Windows 10 Home Edition but it's been tied up doing updates for over an hr so I wont be running Genesis (if it even works) tonight.

Very disappointing release Anthem.

In case the new ARC Genesis software doesn't present a meaningful error message about missing capabilities of ones Laptop/PC they should add that to minimize support requests.
I'm not ready to remotely guess where someone complaining about the software doesn't meet the requirements.


In case it won't work on my system I might just wait another 1 or 2 new version releases, it's not like the old software didn't do the trick...




So did I get this right? The STR specific feature is automatic phase alignment of Mains and Subwoofer. That should help some clueless or in case there is a strain in the back and you can't reach those subs phase knobs...

Is it worth running again for an MRX 1120?

Hi,

What's the consensus on re-running ARC Genesis? Would it improve on anything?

Thanks

Looks like it doesn't have a true curve editor, just some more adjustment options for the standard curve.

I was expecting to be able to fully adjust the curve. I am disappoint.

Yes, but it's quite enough to create a Harman/house target curve.

It's definitely an improvement from almost no options in ARC2. But I'm not sure why they didn't finish the job and allow full customization like their competitors.

That's my understanding, too. With my 70-yr-old back and knees, and the need to take the grilles off the subs to adjust phase, I am delighted to have an automatic option. Eventually, I may take independent measurements to see if I agree with its computer-brain.


And, THANKS for the link to the download. M.

Is there a plot available anywhere showing those two targets overlaid?

Tonight I made my first measurements and corrections with ARC Genesis, running on a Windows 10 laptop and working with an STR Preamp. Some observations:
  1. The increased flexibility in the target curve is welcome. One thing one can't do is add a 3kHz dip ("Gundry dip") to a profile or other arbitrary PEQ.
  2. The GUI is different and it will take a while to figure out where everything is.
  3. The auto phase adjust is a nice feature. I hope the next version won't use very loud sine sweeps, which activated my (usually slight and occasional) tinnitus way more than the main calibration sweeps.
  4. I have no idea how the "listener distance" settings on the STR interact with the automatic sub phase adjustment. Presumably if the former are changed, the latter must be run again (which I'm hesitant to do because of the high sound levels).
  5. To me, the sonic results are better than ever, both through the midrange and HF and in the bass -- perhaps partly because I forgot to reset phase after putting the STR into my system.

It's not a lack of a feature...here is a quote from this article:

https://hometheaterhifi.com/reviews/audio-accessory/audio-calibration/anthem-room-correction-arc-system-part-1/


ARC does not calculate distances between the speaker and microphone. These need to be manually entered using the on screen display of an Anthem AVR or Pre/Pro. This is the one downside of the USB microphone. It is not possible to accurately estimate the delay from the ADC and USB encoder in the microphone, and the USB decoder in the computer. If an analog microphone and preamp were connected to one side of a stereo USB sound card locally at the computer, then the other channel could be used as loopback for a timing reference.

I see a major upside in placing the entire analog signal processing inside the microphone, and little downside in having to use a tape measure, especially since some room EQs appear to make significant errors in the automatic distance measurement.

It's not strictly measuring physical distance. It's for setting delays, so the auto measurement is compensating based upon that, which often results in a distance measurement being reported that doesn't match the actual physical distance.

Bottom line: I hope you haven't been manually "fixing" the measurements that the auto EQ has been providing!

I don't think ARC gives you the option for tweaking the timing..just inputting the speaker distances that you manually measure.

Arc Genesis First Run. Most channels set +3 or more DB? Thoughts? PDF File included

Hi Everyone,

I just tested my first Arc Genesis run on my AVM-60. I noticed that almost all the channels were set to +3db or more after the run. Does that seem right?

I'm kind of new to this whole room correction.

Any chance someone can check out the PDF file I attached and give me any feedback?

Thanks everyone!

From what I have learned, a +3db is fine but any more than that then ARC would be utilizing too many of its resources to combat the issue. You could set the system wide level up a notch and re-run to try and bring it down closer to 0 db if you felt like tinkering. That said, I have yet to run Genesis my experience is with ARC (earlier generation).

Your sub is to loud, 5dB louder than the mains. (-3 to 2 dB).

So ARC is cutting the sub and boosting the rest to balance them out. It could have cut the sub more (-5) then the mains would be 0 and the others +1 or 2.

Turn the volume/level on the sub down and run ARC again.

I'd tweak until sub and mains are zero.

But it not to bad (no -12's) and usable as is.

Bottom line: I hope you haven't been manually "fixing" the measurements that the auto EQ has been providing!
Yes I know that changing the timing measurements would mess with the results and as far as I know you can't change those measurements from within ARC anyway. My comment was just that having to manually input your speaker distances is not a feature that they left out.

Ok. I only mentioned it because it's not an uncommon misconception by newbies (in general, not specific to the ARC procedure as you've already mentioned).
