Happy MRX 700 owner who has experienced no problems in my year of ownership.

As you noted, anyone who spends any significant amount of time on internet forums knows that the percentage of posters who complain of problems is not representative of the actual percentage of owners who experience problems with a particular product. Forums a a great tool for either problem solving or venting, which tends to present a distorted reality of the overall level of customer satisfaction.

For those who have had an unsatisfactory experience, I'm not trying to dismiss your problems or the frustration that you might feel. Rather, the point of my post is to bring a little perspective to those who might view this thread and think that the majority of MRX owners are unsatisfied with their purchase.

jayray,

Is there a list or page that shows what each firmware upgrade has fixed/implemented for the last few releases?

Thanks
post #11764 of 16452
If you download the latest firmware from http://www.anthemav.com/support/latest-software there is a "Read Me" txt file that has the change list.

50.24 fixed the most problematic issue ie. with ARC and 50.25 fixed an issue for Zone 2 use.
Try the anthem website.

I love my MRX 500 to death, when it's not giving me problems. I love ARC, Internet Radio and the sound is incredible. I've been aggravated from the start with Lock Up issues, but haven't experienced any of the other issues with hiss, popping or what not that others have mentioned over the past 19 months since I first picked mine up. Firmware issues I can understand. I even stated in one of my earlier posts, that I've learned to accept the Lock Up when being too anxious to switch to the desired source at power up.
But now I'm dealing with a very real Hardware issue with an input channel being dead. And I'm going to eat up another $35 in gas driving to the retailer to pick up a replacement. When I kiddingly made the suggestion of giving me a deal on getting into a 700 after all the problems I've had and the price of gas... the shop owner commented that he was sick of these problems and that he had gotten 3 receivers back in a little over a month. In fact...their store demo was down as well. eek.gif
The MRX is a great bang for buck, and I'm not looking forward to having to research other receivers at this price point all over again. Actually...I threw a dollar number out there, the local sales person said Anthem MRX, and that was all I needed, because I bought the majority of my system from them and had had no problems at all. If you Google "Anthem MRX Problem or Issues"...you won't find a lot of links to read up on. But then again...how many people have even heard of Anthem let alone have spent money on their product. Actually...if you just Google "Anthem MRX" you'll find even less discussion overall. People tend to shy away from $1000+ items that nobody knows anything about. WE ARE THE FIRST OWNERS. The fact that any discussion links...come back to this forum, is evidence of it. If I have the chance...I'm opting out of this science experiment. If you had a serious hardware issue from a 2 month old unit that was specifically tested before it left Paradigm...I'd be willing to bet you'd feel the same way. Keep in mind...I haven't even had a single problem with hiss, popping or anything else that other members are talking about......yet. I'm posting this as an obligation to others that are thinking about dropping over a thousand dollars on an MRX...that Paradigm is still trying to get the bugs out of. Some folks don't want to be test subjects.

I miss my money. I've never had such a bad experience like this before.
Hey, they want to do the "tested before it left Paradigm" routine too. But then I called my dealer 2 weeks later and he told me they had supply problems and they thought they could start the "2 week test" on the 19th of July. On the 26th I called (my dealers phone doesn't call out, I guess) and found out they hadn't started yet. Got more of the "tough industry, tough economy" routine from my dealer. Today I found out my dealer is just getting back from vacation on Wednesday. Yeah, times are rough.
Doesn't sound like the "tested before it left Paradigm" helped you in any way. Oh boy. I've found CS to not like to go past "what FW version do you have?" then it's "contact your dealer". Who contacts THEM again. rolleyes.gif

I have yet to take delivery of my 300 due to an extended vacation but can you tell us when the build date of your unit was?

Mine is one of the first produced and I have no issues. Some of these are just luck of the draw.

ARC was run by my installer a couple of months ago. This is my first shot at re-running it due to some furniture and rug additions in the adjoining dining room (was empty when Anthem was set up). I like my Sub graph but I'd like your opinions. All this was done on the auto, not manual mode.



Level calibrations are LF 0dB, Center +1dB, RF +1dB, Surround R 0dB, Surround L -1dB, Movie Sub -2dB

Honeslty, I feel i've paid 1600 dollars for something that will need to be fixed or replaced and it's only a month old, well a month since i purchased it. I personally, don't want to go through a period of unhooking, mailing, testing, fixing, waiting, installing again this piece of equipment.

I 'upgraded' to have a better quality product than I have previously used based on my painstaking research and careful reading of this products potential and benefit. It is disheartening and dissatisfying regardless if it is covered under warranty or not. I would much rather get my money returned but unfortunatley Sound Components' policy is exchange or in store credit only.

When I watch a move it isn't really enjoyable anymore because voice dialog is constantly overshadowed by static/hiss from my center channel.

So sorry to hear about your issues with the MRX. I can honestly say that my 500 is the quietest receiver or preamplifier I have ever owned. I would expect you to get a new unit with zero problems. If you still have his then I would look elsewhere in your setup. What you describe is very rare or non-existent from what I've read. Good luck.

Sorry yours isn't working correctly. Why haven't you exchanged for another unit? There is no point in going through a warranty repair process while in a return / exchange period. This shouldn't be any different than getting a cheaper receiver that doesn't work correctly and returning it / exchanging it.

Sorry, I don't even have the receiver yet. I was just curious if you had an early model.
post #11775 of 16452
I'm in the process of trying to integrate HT and 2 channel audio in the same setup with a couple different amps. I look forward to trying the arc out with a pair of tube monoblocks which I will use for 2 channel listening, and will only use the receiver's amps for HT.

I understand that two arc modes (measurements) can be saved: music and movies. I hope to be able to measure both amplifiers from top to bottom. Will arc allow me to measure the full frequencies for the tube amp, after I've already done my first measurement for HT, or does it just alter the low end for house curves, boosting the lower end and saving that as your second mode? The ability to do two comprehensive and independent measurements would be ideal.

The ARC application allows you to take two separate sets of measurements (up to ten mic positions in each set), and will then compute correction profiles for each set, they are called Movie and Music - but the names are arbitrary, they could have been One & Two.
The two profiles are loaded into the MRX, and can be selected on an input by input basis. The problem is that there is only one set of speaker distances, and one set of channel trim levels (two for the Sub channel, movie & music). So if your configuration changes between Movie and Music and that affects the channel trim levels, or distances you are stuck. (I wanted to use Movie for a wide seating area, and Music for a single seating position - but the single position is not dead centre of the wider area, so I had to compromise)
The Movie and Music profiles would be more useful if they had independent distances & levels associated with them (although for most people they work perfectly fine)

Regards, Mike.

Thanks for your detailed response Mike. I'm relieved to hear that. This is why we need manufacturers to offer us real world features and not all of those horrible frills we never use.

Finally, regarding setting crossovers. Where best to do it: main menu, ARC, or both?

I assume that when using ARC, it's better to manually adjust the sub or mains crossovers in the ARC software only, and not in the main settings menu as well (conflict)? Or perhaps, when one engages ARC, it over-rides the main menu setting so that they work independently? I know, these questions are tedious, but such is the province of A/V calibration (it's the price we pay for the life we choose -- lol). Thanks for taking the time to clarify.

I would be carefull about changing crossovers since ARC usually knows better than we do what settings are correct. Btw, crossovers are changeable in the ARC program.

post #11779 of 16452
I'm looking for verification from someone that I'm using Dolby Volume (modeler only) correctly on the MRX. I'm coming from an Onkyo SC886 that had MultiEQ so I'm missing some of the surround boost that MultiEQ provided.

NOTE: I don't want the volume leveling feature of Dolby Volume, I'm trying to achieve the Volume Modeling feature as described on page 3 of http://www.dolby.com/uploadedFiles/Assets/US/Doc/Professional/dolby-volume-tv-techpaper.pdf

I normally listen to movies at -20 and want to make sure I'm not missing any of the surround effects by not listening at reference.

I have my MRX configured as such:

Speaker Configuration->Level Calibration->Dolby Volume Leveler Amount: Off
Source Setup->Advanced Source Setup>
Dolby Volume Mode: On
Dolby Volume Half Mode: Off
Dolby Volume Cinema Reference Mode: Off

With the above settings and the instructions in the MRX manual it sounds as though I'm only utilizing the modeler feature of dolby volume. Does anyone know if this is correct?

FWIW, I've listened to a scene I'm familiar with and it does seem to boost the surrounds a little bit (or I may just be listening harder). The boost is not as much as MultiEQ, but I'm willing to acknowledge that sometimes MultiEQ's boost seemed excessive.

Do I want to enable those other 2 Dolby Volume features? I never listen above reference so I'm not sure having Half Mode Off or On would make a difference. I'm not really sure what the Cinema Reference mode setting would do. I figure the less "modification" of the signal the better.

Any Dolby Volume "modeler" experts out there?

I've contacted the dealer and I really have to find the time to uninstall and take it over there. Working 12 hours shfts and don't have much time. And to be fair, it WAS the quitest I've heard initially, I couldn't hear anything.

Here is what I did do though: I disconnected the center channel wires and connected the left speaker wire to th the center input. The result: absolutely nothing.

I hook the Center into the left speaker channel. The result: absolutely nothing.

Nothing meaning no hiss/static/popping/crackling etc.

I just calculated my first ARC settings for my new MRX 700.Would someone look at them and make any suggestions e.g. subwoofer placement etc.?

Speakers are Focal 816V for frond. 807 V for surround and 800v Center.

post #11783 of 16452
I posted mine a couple of pages back. The experts are perhaps taking the weekend off and hopefully we'll get some free advice soon!
post #11784 of 16452
Has anyone experienced any loss of audio recently?

I have been having increasing problem with my 700 losing audio suddenly, usually when there is a sudden surge of volume take place in a movie, eg, Cruise and IMF Director got ambushed in a SUV in MI4, and then all 7 channels will be cut off for an agonizing 5 seconds or so and also quite erratically, which means it doesn't always happen at the same spot. I have updated my FW to 50.25 from 50.23 without any real success. All sources have the same issue and regardless of multi-channel audio format.

Any suggestion to test what went wrong? mad.gif

Your charts look good except for your sub. It's freq. response drops 10dB from 50-20Hz which misses the area where you get some good thumps. If you have anything on the back of the sub which may be interfering with it's low freq performance, turn it off. The crossover should be set to it's highest value, generally 150 or 180Hz. If there is nothing that is interfering, another sub that can go down to 20Hz, flat from 100-20Hz, is what you need.

I looked on the unit and box. Can't see anything, and the serial number doesn't give any indication that I can tell.

My first unit was from the dealer Mar 8, the second was a week later. So I've had the second one almost 5 months.

I "think" the second one worked great when I first got it. I remember thinking how much better it sounded than the first one (gurgling noise in LS channel). I had suspected an overall SQ reduction in the first one, so it was reassuring. I'm sure I listened for channel noise when I first got it and don't remember anything. So problems (initial LC noise) started about a week after getting the second 700. I believe I have a SQ reduction here too and I can't tell ANY difference between ARC on or off. I remember noticing ARC quite a bit at first.

In film it is mostly inaudible (or you just ignore it in the sound effect mix), but in several music peaces, e.g. low organ pedal tones it is audible. For me still the one and only real problem with the otherwise great Anthem. And I will not rest badgering them until it is fixed. I want my organ music undistorted!


In case anybody is still interested: The cause for this problem that has been bugging me since I bought the mrx300 is finally found: Andrew from Anthem pinpointed it to a "rounding error inherent to single precision floating point processing". In other words, it is a byproduct of the normal DSP function in the Anthem and cannot be fixed. Everybody here has it, even if most don´t seem to notice it. According to Anthem It is still inside the distortion specifications, but audible under special circumstances like a loud, isolated bass tone, since it is modulated with the bass tone and has much higher frequency. Normally, it is masked by other frequency content. Just for your information. I have decided to live with it, since the pro of ARC outweigh the defect. I managed to reduce the noise by lowering bass level (with which the noise is correlates in volume) by 4 dB and raising for compensation the sub by 8 db. The result has more deep bass below 60 Hz and lacks in midbass around 100-200 Hz, but on the average it gives a similar bass impression without the noise.

Did Andrew state if this is a problem in the D2Vs too? Maybe a processor upgrade or firmware upgrade should fix this I would think. I know that when Intel releases a processor and there are problems a lot of times they will upgrade the BIOS for the motherboards that will address these issues.
