Your audio rack will have more stuff in it, and your power bill will likely be higher than with just AVR running. You will need an extra power outlet. You may have to buy interconnecting wires for signal and the 12V trigger. Also, you may get noise or ground loops.
Both brands make good - i.e. sonically transparent - stuff. You will get the sound of the recording either way.
Ok great, i already have the wires ready to go and always shut power down at night. Do the amps need unplugging? I may run dedicated circuits, I'm an electrical contractor and might run the dedicated stuff myself. A can do job for me. Thanks again guys. Much appreciated.

Not needed. By "extra outlet," I just meant a physical outlet, as on a power strip or something. As for unplugging, I've never unplugged an amp in use. Even to swap speaker wires or something, if it's a competent design powering it down and waiting a few seconds for the caps to discharge is adequate.

I recently picked up an open-box MRX 300 from an authorized dealer, but can't seem to find the CD. Does anyone know if Anthem can supply with a mic calibration file if I give them the serial?

I think they would as long a you showed proof of purchase from an authorized dealer.

Well that's good news. I was worried I just made a costly bad investment. I've emailed them, so hopefully they get back to me soon.

I have an MRX 300 driving a 7.1 system.
The spec sheets shows 80W RMS / channel for 2 channels and 60W RMS / channel for 5 channels.

I just bought a 5 channels X 200W amp that will drive the front LCR and the 2 side surrounds, i’m going to use the MRX internal amp for the 2 back surrounds.
Because there’ll be only 2 speakers hooked to the MRX, will it deliver 80W/channel or 60W/channel to the back surrounds ?
I mean, is the 80W/channel is available for the main front LR only or it can be delivered to any other set of speakers, as long as there’s only 2 speakers hooked to the MRX ?

I’m trying to understand how the speakers power management is working but did not find anything in the MRX manual.

Thanks

I'm not positive but I think it is 80 to all channels. Meaning that each channel has the ability to produce 80 watts.

Ok who actually uses dolby volume? Up until now I've left all of it off since I notice it sometimes obviously molesting the sound pretty badly. What I want to achieve mostly is to boost dialog since we watch movies at night when the baby is asleep.

Am I correct in this interpretation of the manual.

[Level Calibration Menu]
Dolby Volume Leveler Amount - sort of like the main volume knob. It adjusts how much of it's normalization it's doing. Only works if you have Dolby Volume Mode set to 'On' in the [Advanced Source Setup Menu]

[Advanced Source Setup Menu]
Dolby Volume Mode - Enables or Disables Dolby normalization.

Dolby Volume Half Mode - Per manual "When on, frequency response is not adjusted when playback level is higher than reference level." So I'm guessing it only boosts the quiet frequencies, but does not 'tame' the loud frequencies?

Dolby Volume Cinema Reference Mode - This mode will detect whether it is a movie or music you are watching/listening to. If it is music, it wont perform any frequency response changes. If it is a movie, then it will?

Anyone have any suggested settings for just boosting dialogue without altering other frequencies too much? Maybe disabling Dolby Volume altogether and simply cranking center channel up in Level Calibration Menu?

My guess would be increasing the center channel level.

I'm pretty sure that would be the case. Any two channels driven at the same time should be able to produce 80 watts each, if no other channel is pulling any current from the power supply.

According to Home Theater magazine's bench tests, the MRX300 clips at ~120W/8Ω with two channels driven, and ~165W/4Ω/2ch.

Since the amp channels are (I believe, at least) identical, the limit is how much current the powersupply can offer.

I use it for loudness compensation ("volume modeler"), but have never had a use for dynamic compression ("volume leveler").

I wonder if those figures were at 1kHz? I read the article, but they didn't say at what frequency they reached those numbers?

How do you enable "volume modeler"?

I have a quick question about ARC. I calibrated my system and the left front speaker came in around 2 db's higher in output vs the right front speaker. It is a noticeable difference in two channel listening. All my distances are set correctly. Can I manually calibrate the listening levels and still maintain the ARC room correction or will this mess ARC up?

This is the 3rd time I have calibrated my system with ARC and it has happened all three times with the left front speaker being 2 db's higher.



Thanks,
Ted
post #14716 of 16451
My right front is 2dB higher than my left front but it's been that way with all the receivers and pre/pros I've had. Mine is due to the the room and my ceiling being lower on the right than the left due to the AC duck work I ve manually calibrated over the years with my spl meter and it always shows a 1 or 2dB difference. I would manually check the calibration with an spl meter before over riding ARC just to make sure it's not really off by 2dB.

Thanks Legairre,

I manually calibrated with my spl meter and it showed the 2 db difference. I could also hear the difference. So I went into the manual calibration and adjusted all the levels to 71 db's which ARC had for all the other channels except for the right front channel which it adjusted to 69 db's. I guess by setting the channels manually to 71db's it should not affect ARC, correct?

By doing this it definitely had a big improvement with imaging and the soundstage and I know longer hear the left front as being louder.

I just want to make sure if you adjust the levels manually to be equal ARC still works.

ARC calibrates using a very broad range and is much more accurate than be done with a SPL meter. I wouldn't have messed with ARC.

I agree with shrike645 I wouldn't mess with ARC's settings. Is it noticeable with just 2 channel or movies as well?

I agree but it was definitely not acceptable with two channel. It was like sitting two seats to the left when you were in the MLP. So what should I do. I also noticed it drastically with SACD multi channel disc but not so much with Blu-rays.
post #14721 of 16451
Hi Ted, one thing I always try to remember is that this is a hobby and if it doesn't sound right to the user then to hell with what ARC or any other room correction system says. If it doesn't sound right then change it to the setting that makes you happy. In the end all that matters is that you're happy. There's no use leaving it at -2 if you're not happy. While I prefer to leave ARC alone if mine didn't sound right I'd change it.

Adjusting the trims will not affect the 'shape' of the correction 'filter' calculated by ARC, just move it up or down in level accordingly. In your circumstance, I think I would initially do as you have already done, but longer term I would investigate why ARC measured such a difference, but that will require the use of independent acoustic measurement equipment - and that's a whole new ball game.
If you could post your ARC graphs, others may be able to see why ARC did what it did, and offer some advice as to possible speaker position changes or measurement techniques.
Regards, Mike.

How many positions did you measure from? When setting up the mic, are all interfering, near-by reflections (couch back, pillows) accounted for. You should have at least a foot of room from every angle. Also...this may be a stretch, but are you sure there's no damage to either speaker?

Hi All,
I'm in a great dilemma and confuse to core to decide between Cambridge Audio Azur 651r or Anthem MRX 300/500. Let me put some facts here for your consideration before you suggest.
I have been using CA Azur 551r for quite sometime and can't be more happy with the SQ but due to few reasons i decided to upgrade to next model which is Azur 651r (For sure reason is not power rating, happy with 551r power as well).
during my research i came across Anthem MRX series and thought of considering MRX 300/500 against Azur 651r as i already own Azur 551r for change.
Unfortunately there's no local seller who has Anthem on demo and distributor is only interested in selling and not letting me demo.
So i got few questions and concerns before i decided my buy

1. I love CA Azur sound (Detail, Separate, clean & deep), What if Anthem is not the same can't afford to change AVR for the 3rd time in a month
2. According to Anthem Distributor Anthem is excellent for Movies but not good with Music he made this comments especially after knowing that i already own CA Azur
3. According to another former here Anthem doesn't have very good separation of sound between channels and sound feel like coming from around then from that particular channel which is one of the characteristics of Azur
4. One of Anthem's product specialist with the distributor said he believes more on manual settings then using ARC and doesn't really believe in ARC (If i don't use ARC and not sure about SQ better than Azur i don't see any reason of any considering Anthem)
5. Anthem is way more expensive (Azur 651r is cheaper than MRX 300, whereas to upgrade actually i should be buying MRX 500 to be on same level as Azur 651r)

I would appreciate if someone can help me with this as i really don't know about the SQ of Anthem much but want to give a fair try,

I can't answer these honestly since I never had the 651. I had the 650 and had major problems with it. It would turn off for no reason, the screen would turn to static and then I would get static out of the speakers randomly. After I had to send it in for a firmware upgrade the static sound disappeared but the picture would still drop out and I still had random turn offs. Oh and I'm not sure what MSRP was for the CA but I paid $1500 whereas the MRX700 was 2k when I got it. The only issues I have with my 700 is random clicks on digital sources which almost never happens OR I will get audio drop outs on Star Trek Blu-Rays and a power cycle is needed to fix. Doesn't happen on any other DVD or BD. It's very strange! Other than that I have no issues.

Thanks rwheelwright problems aside how would you compare the sound quality and sound stage of MRX with the Azur 650 which you used to have or overall how would you rate the SQ of MRX for both Music and Movies? Would you agree with the comment the distributor made that Anthem is more of Movies than Music?
post #14727 of 16451
The Anthem is one of the most musical AVRs you can get. It compares very well against Arcam. And for cinema it is excellent. Your dealer seems very odd in his views, ARC is good.

Anthem tends to have a 'warmer' sound than most though, I like that but maybe you don't, so I can't advise which you should get.

Maybe keep the one you have for now and try to get a demo somewhere ? smile.gif
post #14728 of 16451
Thanks diablo676 well i love warm sound for sure that's one of the reason i don't like Onkyo at all cuz of sharpness. I was used too to have a Marantz 6006 before Azur and i always liked it cuz of the warm sound Marantz produce.
Also my current Minx speakers are more towards the aggressive side so i think warm AVR would complement them well as well.

Thanks btw do you happen to listen to any Azur if so how would you compare it... many forums mentioning that CA Azur is much better in SQ than Anthem and that's what making me confuse.

Anthem is the BEST in Sound Quality.

I would NOT OWN Two of them - a MRX in the small theater and a Anthem Statement D2 in the BIG theater.

I'm no expert so I can't comment too much plus I honestly don't remember much. I do remember being pissed off with the constant clicks from the CA and the loss of a few seconds of digital audio when switching tracks or chapters.

On a side note, we also did a test with a CA CD player (don't remember model but was ~$800 I think) with the CA 650r and it was way too bright. There was also a difference in sound when using my Sony ES CD player switching between digital and analog. The Sony ES has (or at least had) a better DAC than most other cd players at the time. The analog sound was darker whereas using the CA DAC was brighter.

And one more note, I didn't have a complete system yet with the CA. I was a missing the sub so the comparison wouldn't be fair in terms of movies. I just remember being aggravated but the issues I had and don't remember how it sounded. My HT guy stopped selling the CA AVRs after I had so many problems.

My suggestion is ask your HT guy if you can audition one of each at the store and it would be even better if you could take home to test.
