The answer is your laptop's processor is far more powerful than the processors inside the Receiver. This allows Anthem to develop more sophisticated software that requires more processing power and memory to run. Secondly PC's can run pretty much anything you throw at them. So if Anthem decides to make a large change in the software they can be confident a PC will still run it. The processors inside audio equipment tend to be very specialised, no hard disk and limited memory. Many of their rivals rely on the audio equipments processors and as a result are not as effective. I've heard of certain manufacturers using their own correction software widely regarded as inferior in order to use cheaper processors.

It's not the prettiest piece of software but other than the networking issues I haven't had to many problems. The network side of it is a little clunky but hopefully once you've figured it out you can put this behind you and enjoy the benefits as I am now.

Here's a question that's had me pondering for a few days. Anthem instructs users when running ARC to be mindful of not positioning yourself so that you interfere with the measurements (understandable). However surely the most optimum readings would be obtained by ensuring that you march your family or friends in to occupy the typical listening positions. Moving them out of the way when necessary for a particular measurement. Surely the best result will be obtained in an environment that replicates the actual listening conditions? Bodies on seats will no doubt change the room response... Wondering if the answer is yes, but Anthem realises marriages and friendships could be on the line if you subjected them to lengthy calibration sessions! :) Maybe they could bundle a few dummy bodies with the same acoustic properties as humans... :cool:
I've been wondering about this myself.

More fascinating to me is that ARC has been around for 10 years now, and is this clunky to implement. How is it not built into the software of the receiver? I feel like they've had plenty of time to develop a Mac version and a Linux version but the fact that you have to be online and they have so much trouble with that is crazy in 2017.

The real bummer is, this is a review sample for my Beginner Audiophile podcast.

ARC runs on the PC to utilize the processing power of the PC to calculate the corrections rather than an expensive additional DSP chip. As for the Mac or Linux versions, I can't say.

When ATMOS came out Denon/Marantz decided to add a second DSP chip so they could continue provide Audyssey. Onkyo chose not to add a second DSP chip and subsequently dropped Audyssey in favor of the lackluster room correction built into the DSP chip they buy. That's what Chris K said on the Audyssey FB page.

For any existing users, have you tried the soft reset? My network connection went dead as a door nail a couple of weeks ago for several days and the soft reset took care of it. To perform a soft reset, turn the receiver off, unplug it, press and hold the power button for ten seconds (or you can press it multiple times) then plug the receiver back in and power up. This was part of the troubleshooting I went through a year ago. At that time, it didn't help, only a firmware upgrade took care of it but when my networking went down a couple of weeks ago the soft reset fixed it right up.

FWIW. I have a 520 (no wifi) so I can't offer any help there. My receiver also has the IP assigned VIA DHCP.

One thing I might offer up...and it's a bit of a guess but particularly if you are connecting the receiver or trying to connect to it via WIFI you might check to be sure that your router or access point doesn't have "block multicast" turned on. Some do to reduce excess traffic to wireless devices. I'm not sure how the Anthems broadcast their presence but I'd say there is a fair chance that it's multicast.

I've been auditioning the Arcam 850 the HT system at my weekender for a few weeks now. So far to date I've been underwhelmed, even post the last firmware update for that unit and significant issues with bass management that were partially addressed. After initially being excited about a receiver sporting Dirac Live and digital amps, I'm now thinking the 1120 may indeed be the better option. I think a few here have auditioned both units? The reviews on the 1120 have certainly killed it. This would by my second foray into Anthem since my unrelated brief ownership of an MRX-510 that I tested in the role of pure processor in a larger system. I didn't really like ARC back them in that particular situation, but as I understand, the current generation of ARC really steps things up a notch. Judging by some of the other owners here the 7.1.2 ML Motion based system with SLM XL fronts, 50XT, FX, and SVS PB 13 would work pretty nicely with the 1120.

Have you tried the same port number I used?


I just switched it to that, and had my fingers crossed. :) Same result.

I've seen this exact situ a number of times and so far everyone had ended up with the Anthem including myself. I am running a full ML system (very hard to drive) and the MRX does it nicely.

It does this forever.



Then gives me a "Failed..."

I have tried about five soft resets at this point. I cannot find the "block multicast" on my router, but I will dig into that a little bit more.

I found changing the max eq frequency made a big difference. The default with ARC is 5khz, I'm currently down at around 1khz (and still playing around). For those willing and with the knowledge ARC offers a manual mode where you can play to your hearts content.

The frightening thing for me was discovering my 6 year old had stuck his finger through the tweeter of a surround speaker and that a front Martin Logan electrostatic panel wasn't working correctly - yet I didn't notice! :eek:

As you can see a massive drop in the front left after about 1k and same for the surround left after 2k. Just goes to show how things can go unnoticed! The system is only used for movies and to be honest not very much over the last few years for a few reasons. Only just getting back into it now.

EQ is still at 5khz for these screenshots.

Not trying to get OT, but could someone post (or PM me) step-by-step instructions on how to print/post the ARC curves? I'd like to get others' opinions on mine, but am a Mac guy and easily confused by Windows.

Thx.

When you perform a calibration you get a report produced at the end of it. You should be able to print that out as you would any normal document. If you want it in an electronic form then just print it as a pdf file (you may need to install a pdf print driver first). However, if you want to play around with the eq etc and then print the result all you need to do is open the ARC file (.arc2), click on the target button (in the screenshot below I've changed the max EQ frequency to 500Hz) - then press the calculate button to show the resulting curves (then upload if you want to apply the changes to the Receiver). Press print and if required save as a pdf file if you want it as an electronic form. The beauty of ARC is as long as nothing in your room has changed you only need to perform the calibration once - you can then just open the calibration file, make and test changes quickly.


Max EQ target now set to 500Hz and Calculate button pressed. File now ready for printing and or uploading to the Receiver.




Here is the original with the eq set at 5kHz - (note ARC has applied correction all the way out to 5kHz).

Hope that's helpful.

Hi,
Where does one set speaker impedance in the setup menu? I can not find it.

Thanks in advance
Are you looking for a place to tell the receiver what impedance the speakers are so it can adjust for a higher or lower loads? If so there isn’t a place for that. The amps in the MRX models are already rated to handle 4 ohm loads so there isn’t any need to set a switch for it. It sounds like you may have used Onkyo in the past were people had to manually switch the amps to a lower ohms. The amps in the MRX are similar to external amps where they are already designed for lower loads so there isn’t any need to manual set a switch.

Just wading into the process of replacing my aging receiver (Onkyo 5008) and the MRX1120 is among my top choices. I see that many folks seem to lower the top frequency range when using ARC. What's the logic behind this? I would think that the more of the frequency spectrum you cover, the better. This seems to be doing the opposite - covering less of the frequency range. Unless I'm missing something.

Sorry if this is a dumb/obvious question.

TIA.

Not everyone feels that room correction or should be making adjustments above the schroeder frequency which is the transition of sound dominated by room nodes (low frequencies) to high frequencies. Anthem give you the option to set it up to your preference.

Ah! Seems intuitive enough. I'll have to research that, thanks!
