Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 461

The crossover is disabled and the dial is set to 120hz just in case.

And many thanks for the extra information & link, I won'd ask any more questions about room treatment on this thread.

Looking at your quick measures I think if you run ARC with the sub in the front left corner, by the bookcase or with the door open you'll have a graph that rolls off at 25Hz.. Can you run ARC so we can see the ARC corrected graph with it in one of these locations. I think if you see the ARC graphs in one of those locations you might not feel you need bass traps.

The ARC corrected graph for the sub by the bookcase is here http://www.avsforum.com/t/1289533/anthem-mrx-receivers-300-500-700-owners-thread-tweaking-guide/13770#post_23009742

The only other possible position (after I sell my sofas) is front left, which isn't currently possible as the sofa would start to block the door. I can move the sofa and try it there on Friday and re-run ARC.

Thanks for your help and suggestions.

Hello all,
I have to re-run ARC, because of new AV furniture. Can someone please post a graph of what to look for when you take a quick measurement of a sub. What is the ideal graph to look for? Would it be the red line in Johns, perfect graph? Please post if available.

Having trouble finding a setting for the following (on an MRX-500):

Playing music on a USB thumb drive through the front panel; the screen display has all the info for what's playing (Album, song list, etc.)...after about 90 seconds or so, screen goes blank (dark). I have to hit play button on remote to get info back on screen. I looked thru the setup menu, couldn't find a setting....I got to plead guilty about not looking at the manual yet (lazy) figured someone on here would have a quick answer, plus I'm just getting ready to watch a Bruins hockey game.......

if you open ARC and look the graphs(or anyone's graphs in the thread) you see three lines,red, blue and green. The blue is the target your are trying to achieve. The red is how your sub measured before ARC and the green is how it measured after ARC. You want the green to track as close to the blue as possible.

Just a slight amendment to the above - the Green trace is a calculated response, it's what ARC assumes the response will be after the correction is applied. ARC does not actually measure the after response.
Red = measured response averaging all the microphone positions
Blue = target response given perfect measurements, and/or perfect correction
Green = calculated response allowing for red data and processing resources available to the target device (D2v has twice the processing of MRX, as an example)

I know this has been asked before, but does anyone know if Anthem is planning on releasing a new model of these AVR's any time soon?

I'm getting serious about upgrading my Denon 3808, but would hate to buy an MRX-700 now only to find out that in the fall a new model was going to be released. One of the dealers I talked to told me that Anthem isn't in the buisness of releasing new models of their gear just for the sake of selling their customes the newest thing, but rather waiting until a significant upgrade makes it worth the effort.

I understand what you guy's are saying. But I was referring to the quick measure tool. When you choose the sub it projects a graph in real time and I am trying to figure out what I should look for.

In my limited experience it wasn't what I was expecting - if I changed the room, opened doors etc. the graph didn't change until I stopped Quick Measure and re-started it.

Not sure why..

Hello all,

Is there anyone here that owns an Anthem MRX receiver who also owns the PB12 NSD Sub from SVS? If so, i'm interested impressions and how well it pairs with the room correction. Would really appreciate any feedback.

Me too. No matter what i did with speaker placement, no change in the graph. It did not occur to me to try stopping and starting. :-)

However, if i moved things around to where i thought i would get improvement and re-ran ARC, there would be a difference in measurements and corrections, though no change on quick measure.

The PB12-NSD and mrx pair quite well. Your listening room will also have an effect on the overall sound too.

When pairing the PB12 with an mrx, disable the PB12's internal crossover and set the sub to flat after running ARC.

I don't know the answer to your question, but I can say 4 HDMI inputs is not nearly enough. frown.gif

Just a tip of the hat to Anthem customer service. I recently replaced my AVM40 with an MRX700 that had no ARC mic. I'm in Australia. My emailed query to Anthem overnight resulted in a response from them in hours, and from the distributor here shortly after.

As a result a new mic will be with me in a couple of days.

Well done Anthem.

Hello fellow Anthem fans!

I got a 700 and i love it deerly. Lately though, it has been giving me some headaches...

In november my gf and i bought a house, and the former owner of our new house was a model train enthusiast.. He had closed up the garage, so he had a place for his trains.. Long story short, the garage is now my home theatre! I finnished building it about two weeks ago, and here is where my headache began.. I have had the 700 out of its box a few times, put power on it during the 2 months + wait before i could use it again.. Anyway, It started with some odd behavior when loading brd on my ps3. I would get a flash of pink or visual static when it switched modes. I notiched it, but dident think more of it as everything was working - but that was then.. This week i ran my first ARC, and everything was awesome for about 5 mins and i started to hear a scratching sound from my left rear.. I turn off ARC but it is still there. It appears sporadicly, i can not provoke it, sometimes its there sometimes it is not allways in the same scene, but all movies (blu ray, havent tried dvd) Frustrated i turned it off as it was getting late.. Next day i turned on the system and the second the movie started i was blasted by static from all speakers as high as i had the volume.. To fix it i returned it to factory settings and was fine.. After that i updated the firmware and uploaded a brand new arc.. After 5 min the scratching sound was back - left rear.. Now i switched the cabels on the rear speakers to rule them out and scratching moved to the right side. It is 100% sure it is the receiver thats producing the scratching.. I have tried new hdmi cabels, dident help. Checked terminals, nice and tight.. Everything is updated.. I use a keyspan USB adapter.. Im out of ideas.. Is it broke? :-/

Just wondering if this has happened to anyone else before. Was watching a movie tonight and about just over an hour into our movie, my mrx 300 just randomly shut itself down. I quickly checked for heat (i have 2 120mm fans drawing hot air away from the top) but as usual it was luke warm if that. I turned it back on and all was good. Just found it a little odd. Maybe a ghost?

Somebody reported this before and it turned out they had turned on the sleep function.

I've definitely put my MRX to sleep by accident.
post #13820 of 16457
ahhh, does it stay on or just the one time until it shuts off?

It's a one time thing. I believe in my case there is some code on my universal remote that triggers it. Happens maybe once a month and i haven't figured it out yet. You will see Zzz on the Anthem display before it shuts down in Sleep mode.
post #13822 of 16457
Apologies if this has been asked before but am I OK to connect a power amp (Yamaha P3500s) into the MRX pre-outs, which is connected to my to front speakers and run ARC calibration?

Will ARC attenuate it's signal so it doesn't suddenly try to put 360W into each speaker and blow them up (to be blunt)?

Unfortunately it does sound like the unit is defective.

No. That won't do anything.
post #13827 of 16457
In what way won't that do anything?

My methodology in the past with other AV receivers has been to connect one front speaker to the receiver, set the microphone equidistant from both front speakers and play a test tone and adjust the volume until it read 75dB on the sound meter; disconnect that front speaker and connect the other speaker via the power amp to the receiver, play the test tone again and adjust the gain control until it reads 75dB. The MRX will adjust the pre-out voltage to reduce the gain of the power amp during ARC calibration? Impressive smile.gif

I almost bought the 700 last week, but I opted for the Marantz AV 7005 processor instead. My dealer even acknowledged that these receivers were 'buggy", but they do sound great.

I'm not sure what your dealer meant by "buggy" but I have had my unit for 14 months without any problems during my entire period of ownership.

I must admit that the AV7005 looks really nice. I used to use a Marantz sr7002 in my home theatre.

Your dealer said the MRX was buggy???........hmmmm, mine's fine, totally user friendly.. I was also seriously thinking about the 7005....but I also use an Outlaw 7500 amp with my MRX-500. But I started reading about Outlaw amp owners having ground loop/hum problems with 7005 and Outlaw...so that's when I decided to go with Anthem (and also demoing before buying)....
