Forgive me if I've asked this but with Blu Rays through the Oppo , should I use the Through setting on the Anthem Video settings or what is preferable ? I forget and can't find it.

I don't think this has been nailed down yet, but if you have access to a Windows 7 or Windows XP computer I suggest you install ARC on that and redo your ARC setup.

If you find the other computer works OK (gets you a solution just above 70dB without the excess ambient noise warnings), please do send an email to Anthem Tech Support with the details on your specific Windows 8 computer and configuration along with the info about what ARC did on Windows 8 compared to the other computer.

In fact if you look up a few posts here you'll find a follow up from another guy who's having problems with ARC on Windows 8. The 2 of you might want to exchange some PMs to see if you can spot a similarity in your Windows setups that might be out of the norm for other Windows 8 users.



I do NOT think the solution you've got now is unusable for listening tests. It's just the frustration of getting there in the first place.

What guy might that be?

"just advising that a new file has been opened with engineering with the issue reported issue. Hope to hear some info soon."

I have requested if it is reproducible at their end (a number of times) and to date have not received a response. Now my emails go unanswered like I am stone walled. It is turning into anthems dirty little secret. Why not tell me if they can reproduce it after 5 months? No one have a windows 8 laptop there? Maybe they can borrow one and spend the 15 minutes.

^ I've got no inside track to their internal testing. But the impression I got from Nick way back when this first came up was that they HAVE tested Windows 8 and are not seeing the problem.

If that's correct then what's needed is to isolate what's different between your Windows 8 setup and theirs.

Whatever's really going on internally, I suggest you just try again with them. I.E., just assume it dropped through a crack and raise it again. Nothing gained by getting frustrated. Just squeak the wheel again.

Try phoning.

I have separately alerted Nick that there's more than one person here suffering with this.

1. How do you place the mic after the first measure of ARC? When i used audissey xt32 few months back, i placed the mic left n right and infront of 1st position(1.5ft).
2. Do you measure 5 locations only or should i use all available position? Any advantage if i use all mic position?

Read pages 46-49 of the manual. All ARC info.

The default 5 mic positions is more than adequate for most rooms. I have never done more than 5 myself and have always been happy with my ARC results. People with large HT's with several rows of theater seating may find using the additional mic positions useful.
How large is your listening area ?? How many people usually are there ?? What is the seating situation ??

There are different opinions on the mic positions, but the configuration you describe is fine. The idea is to get a good sampling of the listening area.
First position should always be a the MLP, at ear height, with the mic pointed straight-up, making sure that you have a foot or so clearance from walls or cushions behind. The other positions should be at least 1.5 ft, but 2-3 ft might be better. If there are multiple seats used for listening then you should sample at those positions. If you have just one or two seats used, then work around those seats. I have basically one seat used, since its usually just me listening to music (wife says its too loud) or we share the same seat at the MLP when watching movies together . You need to decide what's best for your room and audience to decide what positions, and how many positions, to use.

I have been using a 'baseball diamond' configuration with very good results. MLP being the pitcher, with positions to the left and right (like 1st and 3rd base) and in front and behind (home plate and 2nd base). I have a small HT --11 x 18 ft-- and use about 2 ft between positions. Works great for me, but make your decision according to your situation. YMMV.

@tngiloy

Thank you very much for the usual support. I have a single seat too, so maybe I will try that " diamond" configuration.

Just remember to not do too tight of a grouping.
ARC is 'room correction'. It needs to get a good measurement of the room. Use at least 2 ft between measurement locations.

I tried a tight grouping when I first got ARC years ago, thinking that 'Hey, this is my spot. I'll measure here.' It didn't work.

post #41229 of 42691
on this topic, does anyone know what the arc algorithm does with regards to the main listening position? is it/how much is it weighted versus the other positions in making the final correction curves?

thanks.

ya. assumed so. just curious. ok. thx.

^ One thing that's known for sure is that the Measurements for ARC mic position #1 are the ones used to set the speaker volume trims.

That alone is reason enough to insure it is at the center of your listening area.

So I just completed a successful upgrade to 3.09 from the ancient 2.10 that I had been running for years on my D2V. Things look good, but can't say I notice any differences really. But glad to be up to date regardless. One thing I've noticed, that I never noticed before but may have been there all along - if you bring up the Video processor setup on screen while watching for instance broadcast TV via DirecTV at least, I notice under the "Info" tab that tells you what all the current signals are, that the Film Mode changes periodically on its own, from On to Off, even while watching the same program. This has been confirmed with many different TV stations of varying resolutions, though mostly HD. For instance, tonight The Bourne Legacy is playing in HD on HBO2 HD channel on DirecTV, and while watching the movie, the Film Mode detect under Info keeps changing from On to Off to On to Off, at varying times in the broadcast. Is this normal?? I have Film Mode set to the Default "Auto Detect" setting, as recommended in the Manual.

Let me know your thoughts please.

Thanks!

The flip flopping has been around for generations AFAIK...Have seen and observed it from the start about 6 years ago. I just ignore it.

post #41235 of 42691
I ran arc about a week ago and I thought I'd see what the speaker levels were at. The right rear was N/A. I checked the settings and it was set at Dipole 6.1. I thought I had it set at Dipole 7.1 which is what I wanted. I set it to 7.1 and ran arc again and it came up with the 6.1 set again with the R/R listed as N/A again. The only thing that I can figure out is that in the arc menu instead of choosing 1 in the box I should choose 2. I thought the box was for the subwoofer, but it seems it's for the rear surrounds. Is this correct? I have 2 subs but it seems the box is for the rears. The instructions for arc are some of the worst I've seen. It would be great if everything in the menu was explained.

Yes, that's exactly what's happening. That box in the selections prior to ARC Measurement is for specifying whether you have 1 Rear speaker or 2. If you have 1, then the test is done using the Left Rear output.

Change the Speaker Configuration in the Anthem back to 7.1 (i.e, 2 Rear speakers). Set the separation distance between the 2 Rear speakers appropriately, and redo your ARC Measurements telling it this time that you have 2 Rear speakers. Note that you have to reconfigure back to 2 Rears in the Anthem *BEFORE* doing the ARC stuff as otherwise ARC won't be able to produce the test sweep tones for the Right Rear speaker.

ARC does not need to know how many Subs you have, because the hardware provides no way for it to test them separately. ARC treats your entire set of Subs as a single, Sub "combo". The one thing you do need to do however is set the speaker configuration in the Anthem to "1 Sub", even though you have more than one. The Sub Volume Trim that ARC Uploads is calculated assuming that "1 Sub" will be set in the Anthem. (The only effect setting "2 Subs" has is altering how that Sub Volume Trim is interpreted, so there's no problem fibbing to the Anthem that you only have "1 Sub" when using ARC.)

I just reARCed my AVM50v and switched sub to flat from auto and what a difference it has made. Wish I knew this a long time ago. Any other suggestions for ARC settings to make it sound even better?

For mic placement I basically used 6 placements; middle of couch, left and right edge of couch and the same settings behind the couch, center, left, right.

ARC set my sub at -9.5 while Left is -.5 center is -2.5 right is 0 and left rear +2.5 and right rear is -.5. I wonder why sub is set so low.
post #41238 of 42691
^ Presumably because you have the Sub's own volume knob turned up more than is needed.

You were supposed to set the sub level at 75db. Not where the sub manfacturer has made volume marks

I am running 3.09l and I noticed something new while playing a blu ray. The Audio was listed as DTS-HD-LBR (low bit rate)

I do not believe I had seen that before. Or has it always been how it was listed?

Check if you have secondary audio turned on. That can cause DTS-HD LBR. which is not DTS-HD Master Lossless audio codec
And are you using HDMI and not another type of digital connection ?
post #41244 of 42691
I am using an HDMI, and I also checked to make sure the secondary audio was off. I will double check this evening

Make sure that secondary audio is turned off in whatever player you are using.
There is a possibility it is the BluRay disc you are using. Test with an alternate disc.

What disc were you playing??
It's possible that its specific to this disc and not your settings. If someone else has that disc we can check.
I have never seen that DTS-HD-LBR on my display before. Its a new one to me.
If its using the core audio, like when secondary audio is on, I think it shows up as DTS 5.1 or DD5.1. I have to check that out since I never use secondary audio.

The disk was Doctor Who season. 5. It seems it is disk specific as other blu rays come up correctly

Audio on the box says DTS HD 5.1

Interesting
post #41248 of 42691
DTS-HD LBR is the lower bit rate lossy format used to encode the stereo "secondary audio" on some Blu-ray discs. If can also be used to encode up to 5.1 channels (lossy) intended to be output as a DTS "compatibility" track for Optical/Coax SPDIF connections.

It appears that either the disc, or your settings, were resulting in compatibility track output. Perhaps you had your video resolution from the player set to lower than 720p?

If you want to investigate further.
Download a program (Shareware) called Media Info here. Media Info
Run the program for the particular disc having the audio problem and another that works properly and check the audio format on the disc.
Let us know what you find

I am trying to rack it down. The DTS web page gave me the same description. But I did review the settings on my OPPO 83 and Secondary audio was off and I am using Source direct vidieo and Bitstream audio.

I did serch the disk but no further info
