Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 395

post #11821 of 16451
Hi there - first post guys - just asking a question about the MRX300 paired with a PVA 5 driving a couple of Sunfire CRS-3's with a Sunfire TS-EQ12 sub. There will also be a Sunfire CRS-3C centre speaker and a couple of CRM-2BIP in rears.

I'm limited by space so can't get towers, speakers must be wall mountable, thus the Sunfire choice.

I know very little about hi fi and am worried about being guided to purchase equipment that isn't ideal for what I want. I listen to music/theatre prob 50/50 and music taste is usually rock/metal so whatever I buy needs to be punchy and fast and strong.

I've pretty much decided on the speakers, do people think this amp/receiver combo is a good one to do the job with these speakers?

Thanks in advance for any thoughts.

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.

When you say "when a loud bass is played," what kind of decibels are we talking about here, at your listening position? Would this be noticeable in an average size room where audio is set at 75db at the listening position?

Dang, I pick up my 300 tomorrow and there seems to be a flurry of issues being reported. Just my luck. I wonder if new batches of manufactured product will have these hardware issues fixed, and if I should cancel my order and wait a few more months for a newer model.

Not too many people have noticed this so I'm not sure...

I recently purchased an SVS SB-13-Plus (not currently available in the US, I am in Aus) and it's a great sub, in the limited listening of subs that i got to do i certainly preferred a sealed sub, although this means you need to pay more for the performance. I did get to listen to either a paradigm sub 12 or sub 15, i can't remember which is was, it was way out of my budget (prices over here are a bit higher than you guys) and it was very good. I can't say how mine SVS compared to these, I tend to think the Paradigm might be a little better but the SB-13 is very good. Anyway, if i was in your position I would look at either the paradigm Sub12/15 or SVS have a new SB13 coming out very soon, i think it will be an Ultra and will be better than I have. In the price range you are looking at, I think SVS will out perform the Paradigm Monitor subs but the Sub 12/15 are exception from what i heard in my limited listening (maybe someone like Jayray will be able to explain the difference in performance)

I hope this gives a little bit of help. I was in your position a couple of months ago and wanted to chime in about the SVS, they are great subs for a great price, especially over in the USA the service and upgrade options are great. Paradigm in the higher end will also be a great choice.

Also if you are open to the idea of two subs then you will certainly be able to get great results if you add a second sub to any of these as they are all very good on their own, two of them would be mind blowing.

Good luck with your search and enjoy the process.

I have no decibel measurement available. I play from a test CD sinus tones at above average levels. Normally the Anthem says between -30 and -15 on the display when I listend to music, dependent on the recording and my mood. The test tones I play at -15 to -10, but they do not seem to be overly loud subjectively, because the hearing is not sensitive in this low region; then I start hearing the distortion in the high frequency region where the hearing is very sensitive, unfortunately :-).
As I said the distortion is only obvious in very few cases: test tones and isolated very deep and loud sounds like an organ pedal or maybe a large drum. Mostly there is enough high frequency content to mask the noise. It is significant, that nobody else here seems to complain about it, so I would not cancel the order because of this. I kept the Anthem, too. But I thought it only fair to let people know that there is some small bug that cannot be fixed by firmware update and may be audible once in a while.

Noticed there's not too much top clearance for the anthems. Ever have any heat related issues?

The posters here who have issues is not representative of the failure rate overall. Anthem moves relatively fast to fixing issues as they're reported.

Ouiff:

Thanks for all the great Sub feedback. I am definitely leaning towards a JL Audio f113, UNLESS I find a smokin' deal on a used Sub 25. Unlikely as that is! I'm thankful for John and all the others that have offered advice here. Great forum!

Usually it works through the dealer in conjunction with Anthem.

Well your speakers look good but the sub needs some positioning help. The trough from 100-50Hz drops down by 10dB and is robbing you of some good kick drum bass that your sub can easily produce. Use Quick measure to move the sub until you get the measured curve to be flat from 100-20Hz. You then run ARC again and your cutoff will go from 80 to 120Hz. Inches can make a big difference.

This was before and after the 50.24 beta firmware upgrade.
I would have to reset the unit in order to see or hear anything.

Thanks, my issue is slightly different, there was no cracking sound, just dead silence for about 5 seconds, WITH video, and then everything come back, and then it could happen again, very annoying.

If it persists I agree I just might have to reset it to see, Anthem has also asked me to do so but with kids running around need to find time for the ARC.

Thanks for the input.

Did Anthem ask you to remeasure ARC too. If not you could just upload the result that you already did from your computer saved file.

SERIOUSLY! Talk to your dealer about reliability concerns. while you're still new into the sale. I'm on my 3rd MRX500 and this ones going back due to a dead component input channel. New problems seem to be growing instead of becoming fewer from what I'm reading in here. I'm not trying to start trouble...I'm just being realistic.
post #11844 of 16451
I had the same issue that I had earlier with the new firmware. I was watching a new ST TNG blu-ray and I had the CBS sound but when the DTS intro came up all sound went away. It stated that I was getting DTS - 3/4 but there ewas no sound at all. I then started an episode and got nothing so I turned the BD off and back on and nothing. I had to turn my MRX off and on again. I had this issue before I upgraded to 50.23 and now again. Very strange!

My dealer....

I hear NOTHING! NOTHING!!!!

"Well, they are ALL like that"

"You should hear what some of these units do"

Nothing interests him, nothing concerns him, I'm just picky. I think he's lost all interest and passion for what he does.
Just waits for the next "Locate Dealer" to walk in, particularly Anthem. He has no other product line up to date.

I had this same issue on Monday night: put on Saving Private Ryan to demo the opening scene to a friend but stopped it right before the scene started to go have a smoke......when we came back in and started playing it again the sound was out. My MRX700 said "No Signal" but video was being properly displayed from my projector and the display on the MRX said "1080p24" with "3/2" underneath it, indicating speaker output. I turned the blu-ray off first thinking it was the problem and tried a new movie, along with turning on my DirecTV receiver but sound stayed off until I turned my MRX off then on again. Didn't happen the rest of the night.

But then later that same night, while watching "Paul" on blu-ray, the sound cut out for 2 seconds but video kept playing normally and when the sound played again it was still synced up correctly. First time my MRX has done that since I have had it.

I have been running the 50.24 firmware since July 10th and these two issues above are the first I ever have had. Going to update to 50.25 and see what happens.

All in all still incredibly happy with my Anthem :-)

Hello,
I have a rythmik 12SE. I posted my charts earlier on in this thread. The sound is Amazing!biggrin.gif I have my MRX 700 sub setting set to flat. The sub go's way down. I here and feel all the Subsonic info from my LFE channel. Great Sub!

Hello all smile.gif

Own a MRX 700 - loving it! But I am having an issue I was hoping you guys could give me some thoughts on.

Pretty simple ... It's the lip sync (sync of the sound actually).. The sound appears to be ahead of the movie, and I cant correct that through the receiver confused.gif Not all blu rays are affected, and to my knowledge streaming is never affected - this is very confusing. Atm the delay is set to 0.

I use a PS3 > HDMI > MRX 700..

Well that is it. Thanks in advance!

Regards

Anthem fan

Why can't you correct this through the receiver using the lip sync delay? I had to do it with my Oppo. Actually had to use the max value to delay the audio 150ms. It's right there in the setup menu: Setup, Audio/Video Setup and Presets/Advanced Source Setup/Lip-Sync Delay.
