I think most or the problems were in the 700 so you'll probably be OK. If it's from an authorized dealer you're covered if it does have any problems. BTW what sub did you get. Sounds like a Hsu if the sub amp is at 9:00.
post #15902 of 16451
It's from a private seller, which got it in 2011, and haven't used it, because he didn't got to build his HT.
It's an MK sound MX350, in a 3x5 meter room or something.
post #15903 of 16451
Nice sub, sounds like you're going to have a really nice system.
post #15904 of 16451
I hope so. After the calibration, it should play better than the Denon atm. The Denon can't really handle the sub :S.

Got the sub for a nice price of 1530 $ of an authorized dealer, so again a nice deal biggrin.gif

Hi I have just picked up an MRX 500 (ex display) and im trying to update the firmware.

 

I have the keyspan usa-19hs adaptor sset to com port 1 on windows 7 64 biit,

 

the problem im getting is it runs the first 2 parts of the update but stops on the video update the third update it comes too, and pops up data receive error and stops I have to power the amp off to get it back to normal. Any ideas what's going wrong?

 

Also when I change source (ps3 or TiVo box) I get a "pop" from the speakers mainly noticeable in the left front but have herd it from the right front too.

 

When running the arc at first I got error message "could not find anthem processor" but after a few try's it worked.

 

This is my first post so please be gentle!!

 

Thanks for all help Mick

Welcome to the world of Anthem....I had a MRX 700 but ended up selling the thing cause it was too complicated for me. I didn't think the sound was that good anyway,even with the ARC done.

 

To come back to one of your problem when you were running the ARC you got error message " could not find Anthem processor". I had the same problem. I'm surprised it finally worked. The problem that I had was I bought the receiver used and I didn't have the cd programming my computor for the rs-232. I had to call a Anthem technician so he could come with his computer and his rs-232 to get the ARC going.

 

If you are not an electronic genius,forget it. I couldn't even find how to change for ARC sound to regular with my own adjustments on this receiver. I passed way too much time trying to find this and that,try to adjust this and that...forget it...

 

Anyway,I hope you have better luck then me....Enjoy your receiver...

What did you replace your MRX with? I too am finding it so difficult to change any settings!!!! When I bought mine 2 years ago, I had to hire a tech to run the ARC as I found it to be too complicated!!!! When it comes time to upgrade, I will look for another brand which will be much simpler to set it up. I am just wondering which brands will be a lot more user friendly!!! I like the Anthem sound though.
post #15908 of 16451

Sound was ok,but not what I was expected. I read so much about the great sound and everything. I think it's just "houpla" for a little sound difference,not worth the price difference. Right now,I went back to a basic Pioneer 5.1 receiver,which I had no problem making all the adjustments. And truth be known,the difference is there in sound quality but not worth it for me for the price difference. I sold my Anthem receiver the same price I paid for it. I guess I was lucky.

 

If I wanted a better receiver,I would still go used but I like NAD which I thought was the equivalent of Anthem,or very close too anyway. I think the speakers have a lot to do with the sound you get from your receiver. I have Martin Logan speakers and I think those speakers need a class A separate amp=preamp for me to get the best out of those. Can't afford that,so I will sell my speakers and buy regular Polk,or PSB or Paradigm...

 

Let me know what you do.

Also once we get things running there are a few settings I can walk you through to help you tune things.

Thanks Legairre,

 

I'll give that a go and see if it helps with the firmware update and I'll let you know how I get on,

 

I did manage to run arc so hopefully I got that right in the end, was just strange that I kept getting "cannot find anthem processor" message, found it quite easy to set up and run arc in the automatic mode and it dose sound good.

 

What are the best settings for the keyspan? what's the best speed to run it at, are there any other settings to check to make sure I've got it set up correct?

 

Thanks Mick

Make sure the keyspan is configured to run on com ports 1 through 6 with a speed of 115200 . Also check the second post of this thread. There are lots of setup tips that are very useful. BTW are you running a 5.1 or 7.1 system?
post #15913 of 16451
It's too bad people were having such trouble running ARC.

I had no problem at all and this is probably due to the fact that I have a HTPC running Win7 and it has an on-board com port.

With the HTPC, I found running ARC to be no more difficult that running Audyssey or YPAO.
post #15914 of 16451

Thanks for the help

 

I have a 5.1 set up.

The firmware version its on is 50.19 the latest is 50.25

I tried a factory re-set and tried to update the firmware again but it still stopped at the same place, it runs DSP 1 and DSP 2 ok but when it gets to Video Ram Wrighting it still comes up with Data Receive Error and all I can do from there is power the amp down to get the amp working again.

After the factory reset I have been able to reload the ARC file with no problems, so its just the firmware update that's not working.

Mick

post #15915 of 16451
I haven't had any problems with updating firmware either but I also use a serial port that is on the docking station.
post #15916 of 16451
I just did a factory reset, then a firmware update, then ran ARC calibration. I forgot two things before running ARC:

1) Turning off Dolby Volume (Why is this enabled by default even with the latest firmware? Why are all the weird Anthem surround modes set as default for 2.0 audio? But I digress...)

2) Setting the speaker distances

My question is: Should I rerun ARC after this or do they not interfere with ARC or ARC calibration?
post #15917 of 16451
You can set the speaker distances either before or after running ARC, I'm not sure if Dolby volume affects ARC, so I would just run it again.

My good luck has finally run out. I was having an intermittent problem where my MRX-500 would not turn on. Disconnecting and reconnecting the power to the unit solved it for a couple of weeks at a time. Since Thursday night, it has happened every single time I attempt to power it up. I can still cut the power and re-power to get it working, but it's not optimal.

Really don't want to send my beloved MRX to Canada for an extended winter vacation. Anyone have any ideas on what this may be and if there is a known fix or perhaps a DIY part swap?

Disconnect EVERYTHING from the MRX. Move the MRX and just its power cord to a different room -- i.e., a different wall power circuit -- and see if it will power up there (based on the Front Panel display). If not, then it likely needs service. The most likely fault is in the power supply itself, which is probably not something you can fix.

If it DOES power up there, then move it back to its normal location. With ONLY its power cord attached, does it power up? Now, still leaving the MRX uncabled from everything, power up the OTHER devices you normally have on when the problem happens. NOW does the MRX power up? If the answer is NO to either of these, then you have a wall power problem.

If the MRX DOES power up correctly, with the rest of your gear also turned on, but still uncabled, then power down and start recabling things a little bit at a time.

Start with the speaker outputs. While you are at it, check the other end of each speaker cable. Even one stray hair of wire can short that cable and cause the MRX to go into protection shutdown.

If the MRX will still powers up without problem with all speaker cables reconnected -- check using the built in test tones -- then start connecting your other stuff to the MRX one cable at a time. Start with the TV. If the problem returns upon cabling a device then you have found the culprit. That device might be faulty, OR you might have something like a "Ground Loop" putting unwanted voltage on that connection cable.

Thanks for the great trouble-shooting advice Bob! Here is the history, and in all three set ups I experienced the same power up problem.

1. MRX straight into the wall.
2. MRX into a Power Wedge, then...

3. All components were disconnected to introduce a PS Audio Power Wave P5 Power Plant and do some good cable management separating audio cables from power.

The MRX has never tripped off while in use, nor does it "attempt" to start and then fail.

I'm guessing based on how you would have me troubleshoot that this is indeed likely to be a bad power supply. Waiting to hear back from my local dealer for next steps.
post #15921 of 16451
^ Another thing to try is to see if it powers up reliably using the Front Panel buttons. I.e., is the problem limited to using the remote control? If so, then obviously the first thing to do is replace the batteries in the remote.

--Bob

Front panel power button doesn't power it up in this state.

My quick fix is to cycle the power to the MRX via the Power Plant. There is one circuit dedicated to the MRX. Quick off then on and everything works great until I power down the system.
post #15923 of 16451
Having a nightmare of a time running ARC all day. Sometimes the computer does not recognize the microphone, other times it does. Ran calibration 3 times on 2 different laptops & all three times the measuring & calculation part went fine but upload of ARC calculations stopped in the middle giving me an error that its not recognizing the Anthem processor. Nothing has been disconnected or moved. I was able to run ARC without problems on same laptops last week. Any suggestions are greatly appreciated. I am ready to throw in the towel.

The fact that it works fine for normal use AFTER your workaround shifts the blame away from the power supply.

There is a portion of the system which stays alive even while the MRX is "off". That's the portion that senses Front Panel button presses and Remote Control commands. It sounds to me like that is failing. Pulling the wall power of course shuts that part down as well, and evidently that's enough to get it to work normally after wall power is restored.

There is a small chance that a firmware re-install could fix this, but odds are the MRX needs service.

post #15925 of 16451
Changed COM ports on the Keyspan adapter. Still same problem. Just says "failed to upload coefficient xxxxxx-xxxxxxxxx". Should I change any other settings for the keyspan adapter? Settings show FIFO buffer size of 16 & baud rate of 230400. The test failed. But when I changed the FIFO buffer size to 8 & baud rate to 115200 test passed. Too much to digest for a computer novice.

Failed to fully upload the ARC settings again. I am wondering if the the problem is with the Keyspan adapter or the Anthem receiver. I am guessing the problem with the Keyspan adapter is less likely as every step went fine except for the ARC upload to the Anthem receiver.
post #15927 of 16451
^ Double check that the USB cable is fully inserted at both ends for the Keyspan. The connection into the Keyspan is typically pretty loose and it is easy for the USB plug to partially come out there.

Also, screw down the Serial cable, both where it attaches to the Keyspan and to the MRX. Serial plugs tend to not make good electrical contact unless they are screwed down.
--Bob
post #15928 of 16451
I double checked the connections for serial & USB cables at both ends. Strange part is that everything works fine until the upload process without anything being moved or touched. The upload just stops in the middle with error message therefore I am thinking its perhaps more than just a loose connection.
post #15929 of 16451
Has anybody compared the preamp section of their MRX receiver to an Anthem AVM SSP? I've had an MRX 300 with a Bryston 9bst and recently got hold of an AVM20v2. Using everything the same including the amp, and listening only to 2 ch music in direct analog with ARC in the MRX, I was surprised the noticeable difference in sound quality in how much better the preamp on the AVM20 vs the MRX. Everything, the instruments and vocals were a big step up. With MRX, the sound was very good, but with the AVM, it transformed me into another universe. Most likely, I will use the AVM20 for music and the MRX300 for movies.
post #15930 of 16451
My only other options are to either get a different USB to serial adapter or reset the MRX & start over. Hopefully the partial upload of ARC data has not corrupted the DSP in MRX. Does resetting MRX erase previous ARC data?
