It s not necessary to redo or upload ARCbafter this fix.

^^^^^^^^^^^^
Anthem have not released any official statement with regards to the models affected.
Various forum members have stated that their MRXs are working fine.
Other members who have taken measurement have confirmed that their MRXs were affected, and the beta DSP2 code corrects the issue.

My personal view is that all MRXs running firmware v50.23 are affected, unless the DSP2 code has been updated.
I can not give an opinion of other firmware as I do not have access to it.
I'm no expert, but have dealt with DSP devices, and firmware, and can not understand how some MRXs would not be affected.

Anthem have responded magnificently, and I believe a full firmware update will be posted some - and this matter will be put to bed.
Anyone looking at Anthem should be happy to continue a purchase - I certainly was smile.gif

Hope I don't get attacked too much for expressing a view.

Regards, Mike.

I'm pretty close to returning my 700. has anyone heard back from Anthem in the last few days? I've sent e-mails for support twice now and have not heard a word in response. Not even a "we have your e-mail".

Have you checked your spam folder to make sure it did not end up in there? I'm guessing that a short email with just a link to a file cold get flagged pretty easily by some spam filters.

You should be able to call them as well, this would be a good idea. If you are not in North America, there may be some delay on getting the beta, you should work with your local Anthem Distributer if you are not in the US.

I've had a few emails that did not get responded to immediately, but probably becasue they were more complex. Simple requests like this Anthem is indeed usually pretty responsive. smile.gif

I initially contacted tech support here: http://www.anthemav.com/Contact-Technical-Support

My initial contact was on June 13 @ 20:56 and received a reply on June 14 @ 9:37.

I'm not sure why it's taking them so long to reply.

Since I don't have any test equipment, I played a bass-heavy audio track with all speakers disengaged except for the sub. There is no question that I can hear a difference with ARC on and off. With ARC on, the bass is more clearly defined, tighter, and I can barely hear any vocals coming from the sub. With ARC off, the bass is more boomy and vocals are more clearly audible. I didn't make any changes to the setting, including volume, during my tests.

Based on my informal testing, I concluded that ARC is working on my 500 with 50.12, at least for the sub. Or am I wrong to make such an assumption?

Anyone have other ways to test for the issue?

That seems like a good way to test the sub correction and the result seems to confirm ARC is working.

Thank you for the feedback.

Maybe this is a test that other mrx users could use before deciding to install the beta firmware.

I have upgraded to 50.04, I realized the audible subwoofer level has lowered to a more reasonable level, my ARC sub charts shows the target and calculated curve is much lower than the measured, I would say its working now!

I got my MRX300 just over one month ago, and it already had the latest firmware installed (v50.23), so I would assume all new stock to be the same. You might want to contact Anthem Support to request access to the DSP2 beta (v50.04) if you find that the ARC bug is affecting you. Or you could wait a few weeks for the Official update to be posted.
Enjoy the new toy,

Regards, Mike.

I didn't realize that updating to the new firmware required a re-measurement.

Based on posts I have read so far, users were just uploading the new firmware without re-loading their ARC settings.

I sent an email a few days ago for the beta DSP 50.04 but heard nothing back so today I called a spoke to Andrew who promptly sent me 50.04 to my email. I had to select the Com port manually, firmware went very easy. I played some 2ch music and some of Jurassic Park T-rex scene from the Blu-ray, everything sounds great, I can't tell a difference from my previous 50.03 DSP firmware. Looks like certain numbers of MRX receivers have a problem but not all.

I think that Nerd is simply stating that his original ARC graphs showed that the calculated response should have been lower overall than the measurement response, and with the DSP2 update his ears are confirming that is the case.
No new measurement or upload should be required, according to Anthem.

well finally got it set up, and ran ARC, was pretty simple to do so, i have my results here and i need to turn sub up next time i run it. But a few questions first, i haven't had time to sit and read through manual, but i run my fans on 12v trigger, and i tired to set it so i could run the trigger on the zone 2 so i could control my fans separately, but it doesn't seem to switch them on when i change the main trigger to - and have the z2 at *. But when both are set to * it works. Also on the display beside dobly true HD, there was a 3/2 what does the 3/2 mean? Other then that i was very pleased with the results, unfortunately i wasn't able to use sub as when i was finished and popped a movie in my landlord came home and figured i better not run the sub lol. Now when i ran ARC i had to use my desktop, wich is 6ft away from the couch to the side. The fans were pretty noisy, does anyone think this could affect my graphs? I have a serial port so i didnt need the usb adapter, but i could always pick it up and borrow someones laptop. Anyways, let me know what you guys think, thanks!!

If there had been a change in the ARC software itself, than you might have had to re-measure. For a firmware update alone, no need to re-measure (unless the firmware directly impacted something that was key to how the ARC software measured your original mic measurments, for example if the sweep tones where changed or something along those lines).

A few thoughts:

1) Yes, if you run ARC again, turn your sub up just a little bit. However where it is now is good, so no need if you don't have other reasons to re-run ARC.
2) You may want to consider setting your sub to "Flat" under the advanced options.
3) You posted your graphs without the calculated curve. Re-post with the calculated curve and make sure that what you uploaded was after you hit the "Calculate" button.
4) I don't see any reason you couldn't run the trigger from Zone 2, however this would mean you need to turn Zone 2 on when ever you want your fans on. Is this what you were doing?
5) The desktop should be fine. ARC attempts to remove any constant fixed noises before it runs its calculations, so the fans (assuming they were constantly running) should have had little impact.
6) 3/2 is normal. I'm not an expert on the meaning of what the front diaplay is showing. But I think it means 3 Front speakers (Left Front, Right Front and Center) and 2 Surrounds (Left Surround, Right Surround). In other words, 5.1. But If I'm wrong on that, I'm sure someone here will correct me! smile.gif

^^^^^^^^
With regards to the front panel display, it is telling you the input configuration, as in it is receiving signals for 3 mains and 2 surrounds.
How many channels it is driving will depend on the processing mode you're using, and the speaker configuration connected.
Repeated presses of the Audio button, or Info button will show both input and output settings.

During playing DOLBY, DD/DTS DRC setting is set to AUTO by default , I found NORMAL is always the same effect as AUTO, while [Late Night and Reduced] will suppress the dynamic range, my question here is, what is the meaning of setting it AUTO if it always equal to NORMAL? How acutally this AUTO works in switching to other modes - if it does swtich?

2- I didnt see where it says flat but i will check into that
3 - i will also have to re post, i guess i took the pic before i calculated.
4 - I was trying to turn zone 2 on and off, but come to think about it, is there 2 trigger outs on the back? 1 for zone 2 and 1 for main?
5 - yes fans were constant, and i figured since they were that it would be fine
6 - i also figured it meant 3 front 2 rear but was just curious, i also toggled through the info button and is that ever handy!

here is the graph calculated

Open up the target window in ARC and in the Advanced menu you'll see Set HPF, set this to Flat from Auto.

ARC looks like it has done a nice job with the four speakers you posted!
