If you press up/down on the remote it will cycle you though the available output modes. For heights just leave it on PLIIz.

Thank you i got a tad confused with all this dtshdma talk!

Well I'm asking him, since I believe he means the number of channels are downmixed and the extension is discarded in that downmix, which would give you core in the case of 7.1 > 5.1 = 5.1 core only, (1.5Mbps)

I'm sure he'll answer soon enough wether it's core only or full HD for 5.1 speaker set ups fed 7.1 DTSMA sources.

Wibble. Haha

I'd love to answer all questions but regret that time does not permit. For now:

MRX 310 use of core+extension (Master Audio) is confirmed, and apparently it depends on source material too. Lossy encode never went past 6.1 channels, in the case of DTS-ES, so like Bob said if left back and right back test signals are coming from left surround and right surround respectively, the extension info must be in use for the downmix. I'd prefer to comment further on each new model when it's in stores, or at least after final design approval, which is not the case yet for the 310.

MRX gen1 is something I had zero involvement with until its development was around 90% complete, and I'm not in a position to be resurrecting vendor discussions from before that time... sorry. All I can say now is that gen1 uses completely different DSP hardware and that I don't know in detail what goes on inside.

And Core + Extensions is not Core, even after a down-mix. There's more information in the down-mix.

Folks I think this is good news. The AIX test may be misleading.

I will trade you my cat for her!
Actually love..love..love my mrx..used just as a pre- pro..but i do love the new look of the new models.
If i could just stop my wife from buying shoes
i would pick one up and sell my 300.
Will wait and see how well things go on the new models before i decide to replace...
but....is there really that much of a reason to?
post #15489 of 16451
The more I read the more im thinking. Is/was the 300 the greatest amp ever made?eek.gif

I think it was....
post #15490 of 16451
I'm unaware of any 7.1 pre/pro or receiver that cost a $1000 and sounds as good as the 300 ( which as we all know sounds the same as the $2000 MRX 700). Looks like the 300 is the end of the line though as far as bang for buck goes. It also sounds like the 310 doesn't offer much of a sound improvement if your current 300 target and calculated match pretty close. I'm really not seeing any reason right now to move to a 510 just for 7.1 and a minimal improvement if at all in sound quality. Sounds like 310 would just be a downgrade going from 7.1 back to 5.1.

Sure all this could be proven wrong once the new line is released and I get one in house for a demo but from what I'm reading it's not sounding like there's much of a reason to to upgrade from gen1 to gen2. At least not for me.

Guys, this month October 16th John Soden (the Vice President of Paradigm & Anthem Group) will come to us to Ukraine for the authorized dealers conference to introduce new product lines including Anthem new MRX-*10 av receivers.

If you have any questions, propositions, any requests, please post them right here and I personally discuss them with John Soden.

We can even prepare some sort of appeal letter to Anthem developers from the members of this forum with our suggestions and propositions what Anthem can improve in their MRX models to make it more attractive for us - their existing and future clients.

I'm sure they will study carefully our propositions and who knows ... maybe brought them into life.

With a sub and bass management, some of the the load is taken away from the amp.

In the opposite case, electrostatic speakers where the low impedance comes in on the upper end, the level from source material isn't high enough to pose an issue for the amp. Some of the MRX testers are co-workers at our sister company Martin-Logan, and not one related issue was reported for either MRX generation in use with the elecrostats.

Even after extended listening, the MRX is never more than warm. Not saying to disregard Nick's advice, just pointing out that for my setup, with my listening habits, do not have the need for a separate amplifier.

Thanks for the answers. I plan on running statement for front, statement center and monitor statement for surround. The load might be different from your magnepan but base on what you said and my listening level, I think I'll be fine. I could always add an amp for the front down the road.

I've got a 300 and have pre ordered the 510. IMO the new range is an upgrade. ARC is almost twice as powerful,(I've tried the D2v and more filters means better sound),more flexibility when tweaking ARC, easier and quicker to run, better pre amp stage,more inputs, quicker switching, 4K pass through,iOS and Android control. Usb updates and improved looks.

What did you want them to do,add Spotify?

If you run heights I do understand your frustration but that's about all.

Hello All,
This conversation has me freaking out! I am a proud owner of a MRX 700 for the last 3 years. Nicks answers have only been addressing the 310/510/710. How can I know for sure that my 5.1 system is getting the full HD codecs when watching a 7.1 movie? It would make sense if I set my Blue Player to to output LPCM instead of Bitstream.

By heights I'm assuming you mean 7.1? I think most people are upset about the loss of 7.1 and how 7.1 DTS-HD MA will be down mixed to the core DTS 5.1 track. I'm assuming 7.1 TrueHD will be down mixed to the core Dolby Digital 5.1 track as well.

^ You are jumping to unwarranted conclusions. Have you not followed the posts above about DTS-HD MA Core+Extensions? And in any event, TrueHD has little in common with DTS-HD MA in terms of decoding rules.

In addition, for most people 7.1 means Rear Surrounds, not "heights". The 510 and 710 both support 7.1.

Press the audio button on your MRX remote and yours will look like it's down mixing to the core DTS 5.1 track. http://www.avsforum.com/t/1289533/anthem-mrx-receivers-300-500-700-owners-thread-tweaking-guide/15450_50#post_23788319 . If you want to be sure you're getting the 7.1 HD audio on a 5.1 system switch your player to LPCM.

Also if you hit the up/down navigation buttons after pressing audio you'll be able to choose all the available non HD audio fomats.

So Bob are you saying the MRX is decoding 7.1 HD audio to 5.1 HD audio even though the display shows DTS 5.1 not DTS-HD MA when pressing the audio button? If so I'm confused because a non HD audio (plain old DVD) shows DTS 5.1 when pressing the audio button just like a 7.1 DTS-HD MA does on a 5.1 system
post #15500 of 16451
^ I'm saying we are still trying to get a handle on precisely what this decoder is doing, but we know for certain it is *NOT* just decoding the DTS core: The Rear Surround channels are not being lost.

Are you sure you don't have Secondary Audio enabled in your player? That would force DTS Bitstream output from it instead of DTS-HD MA.

ETA: I'm only discussing the new units here -- 310/510/710.
--Bob
post #15501 of 16451
I don't think they are being lost because the manual says on page 15 section 3.2 "If you are using 5.1 speakers, use the Surround outputs and set Aux to Zone 2 so no sound is lost". I'm not saying we're loosing sound from the center backs, I'm saying that unless the display is incorrect then we're getting the core track.

When pressing audio button the display shows DTS 5.1 for a DVD (non HD audio of course) and DTS 5.1 for a 7.1 DTS-HD MA blu-ray. Unless the display is incorrect when pressing audio wouldn't that mean that both are using the core track?

Hello all,
I am watching Oblivian now on my MRX 700, via my Oppo BDP 103. I set the player to output LPCM. I watched the first few chapters. I then set the player to Bitstream, and I have to say there is a major difference. I don't know if Bitstream plays at a lower volume level than LPCM, but the sound was greatly enhanced set to LPCM.
post #15504 of 16451
I'm talking about a 7.1 track decoded for 5.1 speakers. The Core component of a DTS-HD MA 7.1 track only contains 5.1 channels. Ever. Since the Disney WOW, Blu-ray, DTS-HD MA 7.1 track is producing Rear Surround audio in the Side Surround speakers, we know for certain the decode is *NOT* just of the Core component, regardless of what's in the display.

That said, if you have Secondary Audio mixing enabled in your player, a DTS-HD MA track will NOT be output by the player as a DTS-HD MA Bitstream. It will typically be output as a DTS Bitstream (and thus also limited to 5.1). Which would explain what you are seeing in the display.

Again, I'm only referring to the new, 310/510/710 units. (I have no experience with the original units.)

Also confirm that the video resolution going into the MRX is 720p or higher. SD resolution video can not carry DTS-HD MA, and so you will get DTS 5.1 instead.

Bob I obviously can't tell you what a 310/510 or 710 will display. I can only say what the 300 is displaying.

Ran ARC and told ARC my 7.1 system only has 5.1 speakers. From the pics you can see I'm running 1080p/24 as my resolution and the second pic shows what is displayed when audio is pressed. Secondary audio is not enabled.


post #15509 of 16451
Legairre, we know these things:

1. Results vary by disc. Even two test discs do not even lead to same result (AIX vs WOW). So, do not draw conclusions from just a few discs, whatever they may be.

2. The MRX gen1 display is showing conflicting info. I have no idea whether this was intentional and has some hidden meaning, or if it is just a glitch. So, do not draw any conclusion from this either.

3. Whatever the result, what's to say it's the wrong result? The model is dts-certified and so far nothing says that it works differently from anything else that underwent the same certification.

If I get a chance I'll try both test discs on a MRX 700 with 7.1 output but I don't have one hooked up right now.

How exactly?

Also make sure all processing in the player is turned off, especially dynamic range control. Other things are bass management (set all speakers to Large, subwoofer On, sub crossover, if present, to highest setting or bypassed), time alignment (set all distances the same) and surround upmix (turn it off). These do not apply with bitstream output, since data is coming straight from disc still encoded, but if any of the above are enabled while output is set to lpcm, the sound will be modified by the player.

In addition, note that player licensing requirements are not the same as AVR requirements (I don't have time to look at exactly what the differences are, but just so you're aware).
