Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 431

Based on the spec on the SVS site, 23-270 Hz +/- 3 dB, I would say no. But, I do agree with Shrike645, set it up in your room, run ARC, post your chart, and let's decide from that. Specs are one thing. Reality is something totally different.

Yes. It's a sealed box with appropriate limiting. And a very, very good sub. Can't honestly believe that SVS managed to put Peerless's excellent XXLS driver and a properly NRTL safety-certified plate amp in a well-constructed box for that price. Even assuming free labor, you can barely build a SB12-NSD for that price. So you did well.

One only really needs a highpass on vented subs, because they go dipole below their tuning frequency and unload.

I run an MRX 300 as a pre pro using an Anthem Statement A5 to power the 5.0 side of things. The lows are handled by a Studio Sub15. Speakers are MA Apex. The system sounds stunningly detailed and airy. I found that adding the power amp even though small speakers allow me to play to insane levels with complete control and composure whilst being remaining detailed and airy. The sound never gets congested or overbearing.

I think AVmike was right!!! I was overthinking things. However, I have tried running ARC a bunch of times and each time I get an error message (0x01). It also says there is too much background noie which there isn't. It's absolutely quiet.

Any ideas?

thanks atabea

"Anthem should be able to better address your concerns since Anthem has OPPO players for compatibility testing and should have their entire line of receivers at their disposal. OPPO only has one Anthem in their office, the AVM50, and if they are not able to confirm the issues on that receiver, they will not be able to offer further assistance. Anthem, on the other hand, will be able to use your exact receiver and the same Blu-ray player and be better suited to replicate the errors. Once replicated, they can have their engineers look at the data and see if they (Anthem) must resolve the error, and if not, can then inform OPPO of what is causing the error so they (OPPO) can resolve them through a future firmware release."

From the Oppo 103 thread, the 103 does not bitstream DTSMA/THHD. How is this an Anthem issue if the 83se, 95, and the Panny 500 work fine?

Hrian HD, I am not sure if you are referring to my last post but, if you are, I do not have a oppo player (yet).

If you want your player to bitstreams, don't get the new Oppo 103/5. LPCM works.

Hi atabea,
Could you post a screen shot of the error message?
Have you tried running ARC in Manual Mode, then go to Tools - Quickmeasure, where you can test each connected speaker and view a real time updated graph - that may indicate what ARC is seeing to give you the error.
I had to completely uninstall the ARC-1 microphone driver, and reinstall before ARC would play nice, but now it works first time every time time.
Regards, Mike.

My 2nd post here.

Anyone having had issues with Vtuner? I have the latest Media revision 1.1.0 software upgraded. I was able in the past to look at various genre, stations in that country so forth. Now I cant look up stations ,especially in Australia. I can only play " Recently Played" stations which work but as soon as i go looking for new, the screen then goes blank and then freezes (cannot go back to home directory). Only way is to shut off and and turn on the reciever to get back to Vtuner.

Yes i have reloaded software again to no avail. Any suggestions?

A number of improvements have been made, if you plan to upgrade, than go to v50.25, the latest version.

AV-MIKE ( a few posts prior) was right. I did have my logic "back to front." WIth that in mind and on the advice of others in this thread, I did call Anthem. As usual, Anthem was friendly and helpful. Man, they really know they ****!!. In a few minutes, Anthem diagnosed my problem: the baud rate in my com port settings needed adjustment. After that, everythig worked as intended. I have since ordered a keyspan usb adapter to avoid future conflicts (I was using a generic cheapy adapter). In my experience witht the MRX 500, and from reading the various "problem" posts, I am more and more convinced that most of the issues are user related and only a small percentage is actually hardware/software related.

Now that things are back to normal, I ran ARC as I had rearranged the seating position as well as the surround speakers. Perhaps the ususal suspects in this thread could take a look-see at the charts and let me know what you think.

My trims are as follows:

Dolby volume level: LOW (not sure what that means----am i supposed to turn this off?)

Dolby volume calibration offset: OFF

Front Left: +1

Center +2

Front Right +2

Surround Right -1

Surround Left -1

Sub -4


In consideration of the charts and the Trims, is my sub a suitable cnadidate to be run "flat?"

Thanks

atabea

Your levels look very good. I would recommend not changing your sub to Flat. Your sub reaches down nicely 25-30Hz, but it is really dropping off at that point. I think what ARC has selected is probably very good.

Your charts look excellent, the only thing I can see that seems a little off are your fronts. You have a very large null at 100Hz and a bit of a low area 1k-4kHz. I'm assuming your speakers are toed in a bit and pointing toward your listening area. If not that may help the higher frequencies a bit. As for the null, I'm not sure there is much you will do to change it. Regardless, ARC has done a nice job helping your fronts out. I'm guessing things are sounding really good right now

Thanks, Tigger, I could never fully figure out how to interpret the graphs but by your comments I think I am getting the picture now. I wonder what is causing the null at 100hz. My sub specs say it should be good to at least 20 hz but the graphs don't lie. Despite those anomalies, it sounds great---Lovin it. Front mains are toed in.

Thanks for all your help!!!!

Moving my sub worked a bit, but it is still setting the crossover to 80 Hz. I tried to bring down some of the low end peaks on my fronts and surrounds by putting in my port bungs, but it didn't seem to change the graphs much. My SBL has a vibration coming from something, I may have to fill my stands with sand to dampen them.

Trims are all now at 0 except for:
FL +1
C +2
FR +1
SBL -1.

I finally installed in-ceiling surround speakers to go with my GoldenEar Triton 2 fronts, and so re-ran ARC. Because the main speakers have built-in subwoofers and GoldenEar recommends to use the amplifier's full frequency feed (configured as Large, sub: yes) I am using different Movie and Music settings, with a 5.1 and straight stereo configurations, respectively. I have connected the main speakers via LFE which is necessary as the MRX 300 otherwise strips the low frequencies in multi-channel sources when configuring the mains as Large, sub=yes.

Here are the charts:

ARC Movie 112312.png 64k .png file
ARC Movie (ctr & sub) 112312.png 21k .png file
ARC Music 112312.png 34k .png file
Targets 112312.png 67k .png file

ARC set the levels at:

FL +1dB
C +1 dB
FR +2 dB
SR -1 dB
SL 0 dB
Movie sub 0 dB
Music sub 0 dB

A few observations and questions:

1. The slight differences between the Music and Movie measurements for the fronts are surely due to slight differences in placement of the microphone during the two rounds of measurements.
2. RL is by an open hallway, about 1 ft or so from back wall; RF is close to a corner, about 1' from the right wall. I have acoustic panels behind the mains, and to the right of FR against the right wall (that don't appear to be that effective, actually)
3. SR is also in a corner, in the ceiling slightly to the right and behind the listening position
4. Before running ARC I tried to match the levels of the two subwoofers with a sound level meter and the built-in level noises in the MRX. I got FL to 71dB but even lowering FR's subwoofer's level control to the min it got to about 80dB
5. I seem to have a massive null happening between ~35Hz-150Hz. What's going on there? ARC doesn't appear to be able to correct this very well at all
6. Why is there a discrepancy in what ARC is doing around 450Hz on FL between Music and Movie modes?
7. Any other observations? What do you think of this?

Thanks!

I have the same problem with the Vtuner on my MRX-500. I didn't try it before updating firmware and media software to the latest versions of each so I can't say whether it worked with older revisions. I know there was an earlier mention of the problem in this thread, but I never saw any answers. I work around it by using the vtuner website to add favorites, but it's frustrating to not be able to browse stations.

Hello to all,
is there any ios/android control application for the mrx series? or soon to be one?

thanks

Been awhile since I have contributed (ok truth be known, quite some time actually)

Thank you Jayray for your prompt response to my query back than. Am relaxing to music on my MRX 500..and wanted to take the time to comment by saying ....wow ! , just wow !

This AVR just blows me away man Rock solid switching, outstanding timing, excellent bass control, tonal characteristic I prefer, incredible support - Anthem really nailed it with the MRX series, IMO

Glad you're enjoying it.
John

Similar issue here. Prompted by your post, I switched to vTuner and did some listening to various "countries". (Antigua, Cayman Islands, Dominica). All worked great until I got to a point where the screen just went black and I couldn't get the remote to do anything. If it was on a station when it went black it continued to play that station but I could not change it. Another time the screen went black and it locked up during the search process and I never got to a station (remained silent). vTuner is great but it is quirky. I wonder if this has been reported to Anthem?

I agree. You should send Anthem an Email.

Email sent.

Same here now. Weird.
John

Hey John...Why don't you run down the street to Anthem and ask them what's up?

I sent an email too.

Sorry for the late reply. I had to take some time away from working on the theater project. I just wanted to thank everyone for their help in setting my MRX-300 which I posted about 3 weeks ago. Despite by room limitations all I can say is WOW. We had a houseful of people over for Thanksgiving weekend watching the Avengers and The Amazing Spiderman. We really tested out the theater room and everyone was blown away. The whole system sounded great and never missed a beat. Thanks again for everyone's help. You guys are great.

Larry

That's funny. Anthem is working on it.

Thanks!

Ive been following this thread for some time. I have a very odd set-up in that I cannot place the center speak in a perfectly centered position. Basically, I have a projector screen that comes down over a doorway and in theory the center speaker would be in the doorway. If the center speaker is a bit off to the left, would this be a huge issue? Also, the right and left speakers would be to the extreme right and left of a 12 foot wall. This is because they need to be to the ends of the screen which is pretty wide. Any advice is appreciated. I can post pictures and additional dimensions if necessary. The room is pretty much a square about 13x13'.

I've been running a MRX-500 for the past 18 months without issue, big fan of the MRX and ARC. I'm thinking of upgrading/changing my box speakers to a set of Maggies, specifically either the MMG or MG-12 for the front L/R, and MMG-C / MMG-W for the center and surrounds. Anyone have some experience using an MRX receiver with Maggies without a separate amp? I could add a separate amp down the road, but don't want to have to add the amp at the same time I get the Maggies. The loudest I ever listen to is approximately -20 to -15 on the MRX volume display. Thanks!
