You need to turn down your sub a little

Attached are my charts. Any ideas?

Your charts look really good. The only problem is that your sub is turned up too high which is why it's set to -6. Just turn your sub down a couple of notches and rerun ARC.

++1 Agree with all of the above! Turn the sub down a bit and I think the levels will settle back down. Sub chart is very nice.

Thanks George, Ninja12, Jayray and Tigger for a great compliment.
My sub's vollume was the same the first time and all my speakers were around zero after ARC. I will run ARC again with lower sub vollume. Any idea why my speaker levels are too high?

Because ARC is trying to match the volume, for your speakers, with your sub's volume.

So i did ARC again, moved the right front speaker slightly more, the fiance hasn't noticed so i think i might be in luck with leaving it there. Also changed how and where i put the mic. Kept mic at same height for all positions and put it in 4 positions around the couch with 1 position in front of the main listening position.

Set the cut offs for 30 but thinking I might put them back to 40, just to make sure i don't damage the speaker and also just to ensure the neighbours don't complain.

Any thoughts on the graphs now would be appreciated though. I think this is as close to perfect i will be able to get it for now but still happy to keep working on it with suggestions.

This question is going to come down to a number of things. Do you prefer the D/A converter in the Oppo over the one in the MRX? If yes, then the Integrated 225 maybe your best bet for music. Obviously for the MRX you will be connecting the Oppo using a digital source (most of us use HDMI). You would not want to use the analog input from the Oppo if you were running it to the MRX. (see previous post)

Keep in mind however, that the MRX has ARC, which is bound to be a much larger game changer for most, in the sound department, than the possible differences between the D/A converters in the Oppo vs MRX.

If you are considering the MRX regardless, why not start with the MRX and if you really feel D/A converter in the Oppo has a better sound, then consider the Integrated 225. But remember, the 225 will not have ARC for room correction, so you will likely be listening to your room more than the difference of the D/A converters.

Indeed, starting with the MRX seems the way to go. You got the crux of my question, namely, which pair sounds better, the MRX internal D/A to its preamp-amp, or the Oppo D/A to some int. amp via XLR. I have no idea how much you'd lose over the XLR lines vs whatever you lose in the MRX. But if ARC dominates D/A considerations, the diff is moot.

Incidentally, I considered the AudioControl AVR-4 receiver as well, but it seems more analog-oriented than the MRX line, and I'd like to be all-digital, unless there's a compelling reason to use the XLR connection. Interestingly, I was just on the AudioControl website and noticed they have a processor and amplifier pair, the Maestro M4 and the Savoy G3, respectively. (The M4 looks like the AVR-4 without the int. amp, and adding XLR outputs) It would appear, by the connections provided by the pair, that XLR would be the argued for hook up. Additionally, the separate G3 is 200W, instead of 120W for the AVR-4 and MRX 700. So, if one were to judge by the introduction of that pair, AudioControl seems to be making a case for XLR producing a better sound--else why would they compete with their own AVR-4? If that weren't so, they could simply make an AVR-5, much like the contemplated MRX 900. I haven't checked the D/A specs on any of the AudioControl equipment. Also, if room correction dominates the sound quality, then I guess it would come down to whether you needed 200W or not, and which of the room correction softwares was better (though I didn't see any mention of a room correction software at AudioControl--perhaps you are expected to use a 3rd-party offering. Update: I see they have a room correction processor called Diva.).

Graphs look great. More important is how does it sound at your primary listening position and secondly at your other listening positions?

Perhaps you can load the new DSP2 firmware over 50.12 and see if that solves both issues.... would be interesting to see. I would only try this if Piero or Nick says that the DSP2 firmware will work with the older Main Firmware!!!

Yay!

After trying FW 50.19, 50.20b and 50.22. All with different lock up problems of their own... I finally got the okay to go ahead and update the DSP2 portion of FW 50.12 with the DSP2 portion 50.19... and all seems to be going quite well!

Fingers crossed!

Glad to get that news. So you think they look better than before?

I have only listened to music which i have always thought sounded great to be honest, not sure if i have noticed alot of difference on the music side of things although i may playt around and turn off arc to see the difference.

Played 50 minutes of Tron last night and it did sound very good, i guess it's a different kind of sound track but it was great. I thought the low end may be a tad low and was worried about that with the neighbours so as mentioned i will bump that up to 40 (at present it's at 30) and i will watch a few moives over the weekend for the final verdict but it does sound very good from the lmited viewing so far.

Cheers
Heath

Let's look at the actual potential causes of sonic differences here.

Noise. XLR are "better" than unbalanced RCA. They are better because they reject noise better than unbalanced RCA connectors. In most domestic systems cable-induced noise is not an issue, though in some it is. However, a digital connection is generally going to be equally noise-free. So in this case, I'd call the type of I/O a wash.

ARC: Point MRX, no discussion needed.

Bass management: See "ARC," supra.

Power: The MRX amps are perfectly competent to power most systems, but aren't anything special. The 225 is in a different league power-wise, and can play full-throttle for much longer because they have a lot more heat sinking. Rated like an AVR (including Anthem's) it would likely be called a ~325W unit, rather than 225W continuous with 1.5dB headroom. That said, when playing music even at deafening levels, amps rarely run full throttle for more than a few bursts.) If you use very inefficient or hard-to-drive speakers, the 225 is a better choice. The Anthem 225 is the most impressive integrated I've ever seen. It's certainly ballsier than the Classe one I have in a different home. If they upgrade their next-gen unit to have bass management and room correction like the Harman/Kardon 990, I'll buy one for my bedroom.

Phono input: Point 225, no discussion needed.

On balance, to me that points to the MRX as being the better-sounding solution. Though if you don't use ARC or bass management then the 225 is better because it has easily .

By contrast, the DACs will not sound absolutely identical, and in both cases you only have one stage of conversion. (No A/D/A loops.) Both Oppo and Anthem have excellent modern designs, and competently execute them. DACs just aren't a source of sonic variation in modern equipment. (Well, except for some "high end" gear that is incompetently designed, poorly built, or shipped out with inadequate quality-control screening. Anthem may occasionally have some QC issues - my first MRX 300 shipped to me with a dead video something - but their gear is all competently designed for low noise, low distortion, and flat frequency response.)

That is more likely than not the incorrect inference. AudioControl (another company known for its solid design and general lack of BS) probably did it just because they could capture more sales by having separates, as opposed to an AVR. And make higher margins on the separates than an AVR. And get audiophool goodwill by having the expected "high end" parts. (Many functionally deaf people wouldn't be caught dead under any circumstances with a lowly AVR instead of multiple separate boxes doing the exact same thing with the exact same fidelity to the source material; they seem to think it will lead to a revocation of their man-card or something.)

I would suggest keeping it at 30 for a while or at least until you notice speakers bottoming out or neighbours complaining. Based on your charts your L/R speakers have the -3dB point at around 35Hz in that particular position. If you place the cutoffs at 40, you will be taking away some of the output that they are still capable of producing. Remember, all the bass in your system is coming from your L/R pair - it is important to reach as low as possible. In fact, if it was me, I would run them flat (full range) because even at 30Hz the curve slopes down higher, robbing you of 1 or 2dB at the natural speaker rolloff. Before MRX, I ran my B&W 805 speakers with Arcam A85 amplifier pure direct (no filters whatsoever in the chain) and nothing happen, except good sound .

Greetings from across the pond

I Thought it was time to post up my graphs, I can definitely tell the difference with ARC enabled :smashin: Just watched Underworld Awakening ! very good sound on that.

Quick overview on setup,
  • Speaker are mounted high up on walls just beneath ceiling
  • Sub crossover = set to highest
  • Sub phase = 0
  • Sub amplifier mode = on, other options are auto high or auto low

I have these speakers
Movie 2005 - Movie Series - CANTON German loudspeaker tradition (en)
Mounted high up on the walls in each corner of the room just beneath the ceiling (i know not ideal but thats all the choices I have)

With this sub
SUB 8 - Active Subwoofer - CANTON German loudspeaker tradition (en)
(soon to be replaced with a Seismic 110)

So I am unable to move the speakers as they are fixed to the walls although I could change the brackets to moveable ones if need be.

The sub is positioned in a bay window behind a corner sofa so not much room for position change ;(


Here we are,





I checked the Speakers db gain setup in the Anthem GUI and they were all with 2 steps of zero :smashin:.

Should all my cutoffs be set at 120 aswell as the sub?
Looks like there is something wrong with my right surround?.

Thanks for looking

Did you use the DD18's built-in EQ before or after you ran ARC? Did ARC make much of a difference with your DD18?

I used the built-in EQ before I ran ARC. What do you really mean by did ARC make much of a difference? If you're asking if ARC had to make a lot of corrections for my sub, then the answer is no. You can see my sub's FR in the link below. ARC did blend my sub with the rest of my speakers very nicely and the bass is not localizable. It just fills the room very nicely.

Things look good! ARC has done a great job with your limitations.

The Right Surround puzzled me at first as well... than I noticed the scale of your Y axis. It looks like you accidently zoomed out on that graph. Hit the "Auto Scale" button and it should snap back to the standard Zoom level and I think it will look much more like your Left. I don't think anything is wrong with it from what I can make out in the zoomed out view.

As for 120, this is a little unusual, but it appears to be correct based on the way your speakers measured. I'm guessing these speakers are usually sold as a set including the sub and as such have been matched to the subs crossover electronicly in the speakers themselves.

Please, before you ask a question about...

To get a picture as pretty as Jayray's, you really have to have a sub with built in EQ that is run before hand... that is why the red measured line already looks so good when ARC runs. The EQ in the sub did most of the heavy lifting. Then you run ARC afterwards and it cleans up any small things that are left

For those of us that don't have an EQ system like PBK built into our subs... their "Pre ARC EQ Sub" graphs sort of feel like they cheated lol, but the reality is, even if your measured curve doesn't look as pretty as theirs, our non EQ'd subs still usually end up with a calculated curve that is pretty good after we run ARC.

One thing that is interesting though... you know that if you were to look at Jayrays PBK graphs, they would show a sub that has peaks and valleys and a nice flat calculated curve. The fact that ARC measures the sub after PBK has been applied lets you see just how close PBK was able to get the sub when you see the measured line in ARC! (And for those of us without PBK, what our subs would likely look like if we could do a measurment after ARC was applied).

Please, before you ask a question about...

A nice addition to ARC would be the ability to measure after running it to actually see the corrected curves instead of the calculated ones. I don't see why this can't be implemented, the hardware and software are already there.

The calculated curve just like the measured curve is a average for the room. Measuring after ARC is applied the curves would probably not match up perfectly and then Anthem support would be getting more calls than would care to have and spend time explaining something that is normal.

Thanks. It takes time and patience but once you get it, you will always have smile on your face especially when you see others being amazed by your system.

+1 Yup, I can see the headache already... though I have to admit, it would still be a nice "Advanced" feature... even it it were simply using "Quick Measure" in a special mode where it does not reset the MRX and disable ARC. Somethings ARC may think it can fix, that it actually can't... where a reposition might be able to help, so it would be nice to see where a pre-existing issues ARC tried to correct did not actually come close to the target set by the calculated curve.

Guess this is why I really have to take the time one of these weekends to sit down and learn REW (Room EQ Wizard)... I've got the Calibrated Mic and have of course downloaded the software and manual... just haven't had time to play with it or finish reading the manual.

+2. I'd be all for the ability to measure After results as well, or to be able to use QUick Measure without erasing your ARC settings.

BTW, the ARC mic can be used with REW or other measurement programs. It seems about as accurate as the uncalibrated Behringer ECM mic.

I picked up my MRX-500 yesterday and I am one happy owner this morning. I did not get a chance to tweak much yesterday. I ran through ARC one time. After completion, I put in A House of Flying Daggers, the scene with the drums. Wow!!! I realize that I never truly was engaging the surrounds properly. Once I uploaded the correction and played the scene, it was amazing.
Overall - the clarity and detail in music and movies through my limited time is fabulous - and I know I haven't optimized my system yet.
My first attempt at ARC, I turned my sub down as I read a number of posts in this thread and the sub was typically too loud. I overcompensated and it was too soft and was not able to read it properly. Once I upped the sub level, I got it too loud again - oh well.
ARC is a great tool and also a bad tool. You get so much information, I know better now what my speaker limitations are - this is going to cost me some money. I am in the market for a Paradigm SUB15 at minimum, maybe a SUB2
My speakers are as follows:
Paradigm Monitor 9 v.6 for fronts
Paradigm CC290 v.6 center
Paradigm PV150 in-walls for surrounds.
JBL ES250P 12" sub
My surrounds are much less sensitive than my fronts and centers which are easy to tell by my level measurements.

FL 0db
FR 0 db
CTR +2 db
Surr R +8 db
Surr L +6 db
Surr Back R +6db
Surr Back L +8db
Sub -8 db
My charts are attached. I would appreciate some feedback. I will re-run again with my sub turned down. I was curious though whether I should expect much of a difference in my overall speaker response. I will experiment with some different sub and front locations. Thanks for any help you can give me. Regardless, my sound is an order of magnitude better than I have ever had now without doing anything else.

If possible find some back boxes for the PVs. It will increase their performance and efficiency. We've used Dynamat for same situations. In most cases, they can be retrofitted.

Thanks for that suggestion. I will look into that. Has anyone used Millenia Series for surrounds? I don't think I can get away with mounting ADP's on wall in our living room/HT area.
Also - how easy is it to get out in-walls once installed. i have not tried to do that.
