So if mains are set at 80hz then 80-120hz is the no flying zone. biggrin.gif


It had my mains set at 80hz.

If Anthem wants to live up to it's reputation it better. wink.gif

I've been sitting on the sidelines contemplating whether or not to replace my AVM20 with an MRX. I must say reports here of bugs and service issues (as well as the lack of any official firmware fixes for some time) has me leaning towards not going with Anthem this time. frown.gif

Audio blackout is absolutely normal when you connect a new device to the MRX, as it needs to remake the handshake (else your player would not know what kind of TV you have).


 

Funny thing is with this 710 power issues, that my 510 has none of these problems. I experimented in the past months, so there was a run with 5 db room gain. Combine that with the ELV1S 5.1 audio DVD (quite bass heavy), and I was in the (-5) - (-10) db range. That is with two Dyno A52SE fronts, (4 ohm, ouch, and 85 db sensitivity). I played at least three songs before stopping, thats ~ 12 minutes. No problems whatsoever, although ventilation turned on of course. A wild guess: maybe it's the voltage? I have 240V here, the last time I heard Canada was mostly 120V.

I don't have any power problems with my MRX-510.

I've had it up to 0 on the dial for close to 10 minutes without issue. This volume is unbearable for me though. My iPhone was showing over 103dB on an SPL meter app.

I quit long before my MRX does.

Funny. I haven't turned it past -15, but I'm using a dedicated power amp with mine.

-25 is the loudest i've cranked my 510 up too... I thought that was loud enough, and had no need to be any louder...

I already said it earlier but yeah, the 710 for me is not different.  -25 is LOUD, -15 is EXTREMELY loud and feels like it is causing damage, and -5 is well beyond deafening

Especially with Klipsch speakers! I may be wrong, but I thought the user in question had mentioned his Klipsch speakers were RF-7s which are rated at 102dB @ 2.83 volts/1 meter .

Hearing loss would definitely be a concern at those high of volume levels.

Hearing loss would definitely be a concern at those high of volume levels.

The reference levels on the 510 seem much louder than my onkyo 875, again, using the same Rotel RMB1565 dedicated amplifier. The onkyo, in the DB scale, we would push into the positive 5+ db range whereas I cannot see going close to 0 on the 510.

You also must take into account the size of the room and the listening distance from the speakers.

I'm currently running legacy signature 3's as my front mains. They're not normally my main speakers in my surround setup but I blew a crossover on my RS850s and I'm still breaking in the new crossovers. The legacies are 23 years old, rated at : 93 dB @ 2.83 V/1m, The RS850's are 6 years old, rated at 90.5dB @ 1 watt / 1 meter. Again, I'm not using the internal amp. The Rotel is more powerful than the internal amplifier on the 510 (especially all channels driven) and the legacies are 4 ohm speakers whereas the 850's are 6 ohm speakers.

Playing music, in 2 channel or all channel stereo, I've never turned it past -20. Reason being, music is generally continuous audio output, whereas movies tend to be bursts of loud and soft content.

I seem to recall that, at least on the first-gen MRX, if you calibrated speaker trim levels to 75 dB of output (in order to calibrate to reference levels), then you are achieving reference level output when the master volume control is set to -10 dB. Whereas on most other AVRs with relative volume levels, if you calibrate the speakers to 75 dB then you would be at reference level at a master volume setting of 0 dB. Why Anthem decided to do this is beyond me, but I think that is the case.

Now, whether the user in question calibrated speaker trims before playing at -5 dB I don't know, but if he did and if the above is true, then -5 dB on typical sources would be ear-splitting indeed! And if a speaker has a dip in impedance at some frequency and you're playing it that loud with lots of content around that frequency, I suppose that might be why it is shutting down.

Does Klipsch publish impedance curves for their speakers? A quick search did not find any, and most consumer gear companies don't publish them. That would be interesting to see one for that speaker though.

No impedance curves published that I have ever seen, and only listed as 8 ohm impedance (or 8 ohm compatible).

Are you kidding me. -15db is EXTREMELY loud?

Dayakch & Frank: I use the MRX510 with no external amplifier as I find it has more than enough power for my needs. Right now, I am just experimenting with the ARC settings and using my ears to judge the difference based on my room acoustics. Your results may vary of course. Right now, I tend to prefer the higher frequencies uncorrected, rather than trying to get the "perfect" flat response for my music listening. I set mine to 500 Hz as there was a significant enough dip around that point that I wanted to correct.

My room is approximately 17'x14' and does not have an open floor plan to another room. It is actually a "bonus room" above the garage with wood floors. It has 8' ceilings that slant at the sides to follow the roof line. I chose the SB-2000 as it was smaller and had a much better WAF (Wife Approval Factor). I am limited on subwoofer placement and the PB-2000 was a bit too big for the room. I called SVS a few times and spoke to three different operators. Two of them recommended the SB-2000 for my room size and one actually recommended the PB-2000 if I could manage it. I played the opening scene of Star Wars Episode 3 and the rumbles did shake the room well enough using the SB-2000. It was much cleaner and more detailed than my previous subwoofer and integrated easily with the ARC room correction software, which makes me a happy camper! The PB-2000 definitely would have more "punch" for movies. Hope this helps!

I've been (and still am) an Onkyo & Integra fan since the 90's. I've only owned Onkyo/Integra equipment and it has always worked flawlessly for me. Just like any appliance, it's usually the people who are unhappy who voice their opinions the loudest, which affects all brands. As someone who is completely new to Anthem and I consider it a "boutique" brand from where I am coming from, I am very happy with my MRX 510 purchase so far. I've contacted their support by phone and they are pretty quick to answer and are very polite. It appears to me that they are actively working on issues and it can often take time to find root cause of a problem. Unfortunately, issues are always a constant in the world of electronics.

I have a 310 and while i would like more power for 2.0 listening for superior dynamics, i feel even the 310 get very loud compared to anything else i have used with similar specs. I van go to -0 for as long as i can take it. I also notice more warmth with movies vs. music. I do not use arc for music either. No need. Not sure what the 710 issue is here. Hard for me to fathom unless there is a design flaw somewhere.

Just unboxed my MRX-510 and hooked it up, replacing my Yamaha DSP-A1. My first reaction was, "where's the volume?" Comfortable movie volume is -20dB and if I were to watch something more at theater volume it would be around -15 or more. I'm driving B&W DM604 S2 mains, CC6 center and little Celestion rears. This is very surprising to me as my A1 would blow the roof off the house with the knob at 12:00. There was no dB indicator so I have no idea where that fell relatively speaking. If I turn on the test sound and do speaker levels, the white noise is SUBSTANTIALLY louder than normal content. Is this normal?

The sound is probably a bit cleaner and warmer but I might just be hearing things. Surround sounds great and I have not run ARC yet. Can't seem to get TrueHD out of my Sony 5100 but I'm sure that's a setting somewhere.

Still getting my Harmony tweaked...

I wonder if the problem has to do with the toroidal transformer ? From what I understand the 310 and 510 don't have the issues but the 710 do and isn't that really the only hardware difference between them? Didn't the 700 have loads of issues too? Everyone I know who had the 700 had to send it back to Anthem, but my 300 has been fine.

I should note that my own personal experience with Anthem (bought my AVM20 new about 10 years ago) has been positive. That combined with some features unique to Anthem has me wanting to stick with an Anthem product (unfortunately, the AVM pre/pro is now WAY out of my price range). Primarily I'm interested in what ARC may offer, otherwise I'm perfectly content sticking with my AVM20.

I must admit though that issues raised here about the MRX series is giving me pause.

It should be noted that not everyone has issues with their 710... for instance I do not.

With the new iPads and iPhones having 64 bit power, I wonder if Anthem will release an app for ARC as I'm sure these new 64 bit iPads and iPhones and soon Androids will all have enough power to run ARC.

If you buy something and it works perfectly, you're less inclined to write a review than if you buy something and you're unhappy with it. Anybody reading these posts might jump to the incorrect conclusion that the MRX 310/510/710 has a lot of problems. I seriously doubt that. Anthem sold boatloads of MRX 300/500/700 receivers and it wasn't because they sucked and people enjoyed overpaying for them. They bought them because they were the best sounding AV receivers on the market and they worked well. That's not to say that a new unit, like the 710, can't have bugs. I'm sure it does. But these problems are resolved with software updates and a bit of patience on the owner's part. There's no point being an early adopter of technology if you're not willing to live with a few minor problems. Of course, if you're having major problems I understand your frustration.

I had an MRX 700 for 2 1/2 years and never had a problem. I replaced it with a 710 because I like new technology. So far, it's been problem free too. Both units powered a 5.1 zone of Totem speakers (rated at 88db sensitivity) and a second zone consisting of 2 Revel F208s (88.5db sensitivity). I've played the MRXs at near reference levels for prolonged periods and have never experienced a shutdown despite the modest sensitivity of my speakers.

I wonder if the problem has to do with the toroidal transformer ? From what I understand the 310 and 510 don't have the issues but the 710 do and isn't that really the only hardware difference between them? Didn't the 700 have loads of issues too? Everyone I know who had the 700 had to send it back to Anthem, but my 300 has been fine.

My thoughts exactly!

I'm also using an MRX 510 with Axiom speakers and a SVS PB13 Ultra subwoofer. No problems running movies/music on a -10/-15 dB volume level. The MRX is positioned inside a closed cabinet, but I'll tend to keep the door open when running it at that volumes. I even haven't heard the fan inside ever...

Same here. I've pushed my 310 pretty hard and never had a problem.

Wonder if the toriod is high enough capacity? Generally they're quite large, larger than regular PSU so in the same size chassis/area? Try fitting this in the Anthem

maybe next generation following x10s. The current mic comes with USB interface, it would need to change to Blutooth or Wifi to be a one-fits-all for handeld devices.... but that might still be too complicated for most audio enthusiats to setup, then it would need NFC for automated setup of connection, but then there are no NFC devices at large.... so maybe two or thee generations after x10s... biggrin.gif ... I doubt they enter that field of tech any time soon...

and btw is there an app for remote control now? the app store didn't find anything "Anthem" last time I had a look! I thought this would be part of the package some time - to be honest - I don't care tongue.gif

-5 db is indeed deafening (even with my A52SE speakers, which are not really efficient) with normal CD content, however SACD and DVD / BD-A are usually much quieter. In normal usage -15 is the max I go, but my 510 can handle even -5 without problems (and with 5.1 content).


 

At the moment the IOS control app is not available, you can request the android one (beta) from support I believe.
