You may have to connect and disconnect the rear speaker. From ch 6 to 7 to have ARC work properly.

We will try to implement this 6.1ch feature into ARC."

If I am reading this properly at this stage they do not support 6.1 and so it seems best that I buy two more rears to go 7.1 and not 6.1 as planned. Going to look at bit messy... oh well

I am not very technical so maybe I am missing something

Which means ARC will attempt to send test tones to both rear speakers and will, of course not get a response from one.

And then he's suggesting you can fool ARC, for now, by moving the output jack for your single rear speaker from the left rear output of the MRX to the right rear output and then telling ARC to retry that unresponsive speaker. You would have to redo this for each mic position.

ARC will then build a 7.1 speaker solution. Which I guess you then proceed to use with your actual 6.1 speaker setup.

I'm not sure there aren't still gotchas in this. I don't have an MRX so I can't be much help on this one.

This is exactly the sort of thing I was afraid of when I asked this question. Unfortunately, my room won't allow for 7.1.

Oh well, back to square one...

That is clear from the manual since it is in the "Source Setup" menu. What isn't clear is if the "volume leveling" part of it is a global setting since it is set in the "Level Calibration" menu and therefore might not be set independently for different sources? For example, I would want Dolby Volume on (just the "modeling" part of it) for music without "volume leveling" and would want both on when watching movies.

Leveling is global, not source specific, just checked it.

Yeah, I'm hoping I'm wrong -- that I've misinterpreted that quote cited from Anthem -- because I think that workaround for 6.1 setup would be pretty annoying.

If that's really the only problem, however, it is reasonably likely Anthem can make the necessary adjustments to the ARC setup application fairly quickly.

Could someone who has received one of the MRX receivers please take a photo of everything in the box, obviously to include the receiver itself.

Thanks

Could this work? Run two connections from the MRX to the single rear speaker, with a Y-connector at the speaker. Now ARC will see both speakers when it sends the test tones, and it will send all back-channel info to the single speaker.

*NOT* a good idea. You are not just connecting the speaker to both outputs, you are connecting those two outputs to each other. That is, voltage from one output is getting fed back into the other output.

The box contains one receiver, one calibrated mic,usb cable to connect mic to computer, mic stand, serial cable, zone 2 remote, main remote, ARC CD with ARC program and mic calibration file, specific to your mic and power cord.
No pics because it has been unpacked and in use.

I know this is primarily a technical forum, but I have a very non-technical question. I currently have a Denon AVR-5308CI and I'm running a Paradigm Signature C3 as my center and two Paradigm Signature S4's as front R and L. I run a 5.1 setup and I'm considering two options. I can sell the Denon and get an MRX-700 or I can buy a preamp to use with an older, but solid Classe 150 wpc amp that I also have. I haven't heard a lot of discussion on how these receivers compare to other options and I'd value any opinions you can share regarding how I should proceed. Thanks! Bruce.

You could get the 700, with no external amplification needed, given your speakers and enjoy ARC's great affect on your room. Paradigm and Anthem have run all these speaker combos during testing of the MRX models.

I am currently sitting on $3000 trying to solve my stereo and HT needs in one magical package :-). I have B&W 805s fronts, matching HTM4s center, ASW825 sub and CM1 for surrounds. For sources, I have Arcam FMJ CD23T, Panasonic BD55 Blu-Ray, a Home Theater PC with an ATI 5450 video card with HDMI capability (and multichannel sound over HDMI), and an HD cable box with HDMI out.

I am currently running a 10-year old Denon AVR3300 that is competent if uninspiring solution. Since I moved recently, I used AVR3300 as center of the merged audio/HT system in my living room. Couple of days ago I hooked up my Arcam DIVA A85 integrated to the fronts, and run the CD player directly into it, and DENON through the processor in for L/R speakers. I got depressed as to how much better Arcam sounds with everything - CD, digital music from HTPC, just about everything - I forgot what 805s can do using Denon for 6 months :-(.

I had some time to listen to MRX 700 when I visited my regular shop (Audio One in Toronto). It sounds very refined and clean, although it sounded a bit reserved. I don't want to pass judgement because MRX 700 was hooked up to B&W CM9 (and later to Paradigm Studios 100), the room was different, etc. Nevertheless, I am sure it would be a step up from Denon.

I have two concerns that are preventing me from just buying it right away:

1) Without stereo bypass, the fantastic ring DAC in the FMJ CD player will be useless for pure CD listening - I may as well run a digital out from it (I wander about jitter in that case - CD 23T has very low jitter on its own). Then again, I would probably get similar sound playing CDs in the Blu-ray player - I don't see what CD 23T brings to the table if only digital out is used.

2) Somebody recently posted the pic of MRX700 inside. Based on what I have seen, the amps have one pair of bipolars per channel and one pair of reservoir capacitors for all channels. In contrast, Anthem PVA 5 or 7 uses 4 output transistors per channel and has much beefier power supply and capacitors. I know that my B&Ws are not a hugely difficult load but they do occasionally dip below 4 ohms and respond enthusiastically to an amp with lots of current and high damping factor. Even moving from Denon to Arcam integrated was a huge step up. As good as they seem to be, I wonder if a combination of MRX500 and a PVA 7 would not be better than MRX700 alone (providing I don't care about HD radio). On paper, they both have the same power but I am sure PVA 7 current makes a difference sound wise.

I know that MCA 50 would bring even more power and current to the table but I am trying to keep to the budget (and in my living room I am sure that MCA 50 would be sleeping most of the time, coasting on a few watts). Obviously I find Arcam A85's 85W pc plenty :-).
post #373 of 16451
I forgot to ask another question: was attention paid to reducing clock-induced jitter via HDMI inputs? My HTPC video card has multi-channel passthrough via the HDMI output (onboard digital audio is sent to the video card and merged with the video signal). If I am to use HDMI for high-res stereo music, will the sound be the same or worse than when using asynchronous USB adapters. I know that in theory the lack of dedicated audio clock when using HDMI can be a source of huge amounts of jitter if care is not taken. Some high end companies (say Arcam in their AVR600) claim that they managed to work around this problem and get good audio via HDMI. How about MRX 500/700?

Hi Dejan,

I've had a pretty wide range of loudspeakers conected to my trusty Beta Unit 27 (MRX700,) and from the start, it was clear to me, and all the other testers, that the amp section of the 700 is stout. The most similiar load I used was our Signature S2v.2.
Even driving the S2's full range, the MRX700 was easily capable of room-filling volume.
It is important to note that while they would play plenty loud, the real test (for me anyway) is the quality of power. Things like smooth treble, and a rock-solid bottom end, indicitive of a good stiff power supply. Many of the testers made similiar comments even before running ARC.
Add ARC, your subwoofer and I'd guess a 60Hz crossover, and I suspect you will be a very happy listener!
Of course, with pre-outs for all channels, your future options remain open. Keep in mind, to gain just an additional 3dB of output will mean an outboard amplifier of at least 240-250 wpc.
Hope this helps,
Vheers,
Brian

I'm considering buying a ups to protect my av equipment, which is about to include the mrx700. Does anyone else have any experience doing that? Also, does anyone know what the max power draw of the mrx700 is?
post #376 of 16451
Can the video processing be completely bypassed in these receivers?
I have to use external video processor in my setup with sim2 host, so I would rather not have video signal manipulated twice.
If I get new Oppo BD 93 , it will have 2 hdmi outs . If I connect one to the PJ and the other one to the receiver it likely will work , but I'm concerned it will cause some problem with lip sync. What do you suggest?

Hi, Brian - thanks for the prompt reply. So what you are saying is that I should not form opinions about sound by looking at the amp guts :-). It makes sense - Arcam A85 that sounds an order of magnitude better than my Denon receiver has 'only' one pair of bipolar transistors per channel and while it has a thorodial transformer, the reservoir capacitors do not look huge (granted, the power supply has to serve only two channels). Nevertheless, it sounds as if it has a firm control over speakers. Seems like MRX700 is similar in that regard.

I fully agree with you that quality of the sound is way more important to me than quantity. As I said, I can never get Arcam to show signs of distress, even though it has 'only' 85Wpc. It implies that I play my system at room filling but never ear bleeding levels. Therefore, the issue is not whether MRX700's 120Wpc in stereo can play lound, but whether it will have enough current to control the 805s' woofers and produce tight and controlled bass and clean and resolved highs. You seem to indicate that it should, and with ease.

There is a through mode that passes the incoming signal with no processing.

Hi,

I'm in the process of setting up my new MRX 500. I have a Bell PVR and a PS3 connected to it via high quality HDMI cables (new high speed Monsters). I havent run ARC yet since I had major problems with a USB to serial Nexxtech device...it simply couldn't communicate with the MRX. I have ordered the recommended unit here on the blog.

My main issue so far is the sound dropping/loosing sync with both my PVR and the PS3. Video stays on but the audio is lost. After I cycle power on the MRX everything comes back...very strange. Has anyone else had similar issues???? Jay/Nick please comment.Thanks

I use $6 monoprice hdmi cables on both my PS3 and SA8300 PVR and no syncing issues at all.

I use an APC power coniditioner/surge protector for my HT. The model I have does not have a battery, at the time it was about $1000 more. They have come down in price considerably. You should check them out. They have been doing power correction and protection for a long time.

Please contact tech@anthemav.com for any issue that requires technical support. I do not always monitor these threads, in fact I usually don't except when something is new or someone points me to a discussion.

Andrew and/or Piero will work with you on diagnostics and contact your dealer if necessary, possibly to see whether the problem travels with the unit or stays with the system. There would very likely be questions before answers. Breaking your system down to a basic one with one source, MRX, and TV using the same power strip might be in the cards. The issue is new to me and we need details about the conditions not just the connections.

Yes. Electricity takes path of least resistance. Speaker impedance might be 6 ohms. Impedance at the amp's output is usually well under 1 ohm. Guess where the other amp channel's output current will want to go if outputs from two channels are in parallel and the signals coming out of them aren't identical.

Although 6.1-channel speaker config isn't very common we're working on adding a "one back channel" configuration to MRX ARC.

Thanks Nick for your excellent support on this forum and to Anthem for addressing issues so quickly

I will be speaking to my dealer tomorrow to order the seventh speaker now that I am aware that 6.1 is not yet supported. There goes the budget!

I like that! Heck you could put a few fake vacuum tubes in there as well, with just the filaments powered and glowing, and REALLY impress folks.

If anyone complained you could explain they were intended as lamps so folks could see the rest of the electronics better.

At least one hi-end* CD player and pro* mic preamp have tubes that function as nothing more than "glow things". They both perform terribly, tube or no tube, but have their fans.

*so-called in these cases

OK, in all fairness I was comparing MRX 700 and PVA 7 assuming that all the components I saw in the pictures are real and actually hooked up :-). My point was that all things being equal, amp with a single bipolar transistors per channel will have a smaller damping factor than one with multiple pairs, providing that both amps have been executed competently (multiple pairs need to be, well, 'paired' to avoid distorsion when multiple devices are running in tandem).

Again, damping factor is just an indication - a dumping factor of 200 for PVA 7 promises tigher control over woofers. In the end, it all goes down to how the components sound, but I was assuming that MRX 700 and PVA 7 sound similar with PVA 7 having more current capability. Throw in empty cans around small power caps and all bets are off though :-).
