Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide - Page 1303

post #39061 of 42678
Thanks everyone for the suggestions. I used to have the 2 subwoofers right next to the LF/RF speakers. Recently moved one of the SUB to the back of the room (25x18), now they are in diagonal corners. So it's the first time running ARC again for about 2 years.

I have dual subs in my system, which are located by my main speakers. Each time I measure with ARC, I get a null around 35-45Hz, when I measure them together. Yesterday, I tried measuring them one at a time, with strange results. When I measure one of them alone, I get a nice measured curve, that show no indication of the null at all. When I measure the other one, the curve shows back up. So I guess they are cancelling each other out at those frequencies. I tried switching the phase 180 on the one that produced the null, but then the curve measured much higher in volume it looked like to me. I was using quick measure, which to me is more difficult to read that the standard graphs. ARC does smooth the graph pretty well, but I would like to find a way to negate the null. Any suggestions?

Hi I have an electronics question regarding my D2v2. I think I may have damaged one of the 12 V DC triggers. Is anyone familiar with the circuitry ? Is it easy to repair. My D2v2 is out of warranty. Any suggestions ? Thanks
post #39064 of 42678
Subwoofers are a strange beast.
It is very easy for a sub to set up a standing wave. If the wave is reflected it will cause peaks and troughs. I had the exact problem with my subs (JLAudio 113s).
You indicated that when you changed the phase 180 degrees, you got a peak.

Unfortunately, there is no easy answer.
I found that if I placed the subs on pedestals (8" high) and then repositioned the subs, I could minimize the reflections. Also trying using acoustic bass panels (like Cathedral panels) to help control reflections.
In addition, I set my subs as master and slave, so ARC thinks it is only one sub. (Remember that low bass is non directional; the human ear is not able to detect where the sound originates.)
ARC was able to correct the sub curve.

For fun, try this site to see the impact of reflected waves http://www.hunecke.de/en/calculators/loudspeakers.html

This should essentially yield the same result as "Calculated" from the graphs right when i do this?

There have been a lot of long posts recently so I will just summarize by saying Targets customization is done in the ARC software on your PC AFTER room/system measurement and BEFORE uploading. So you can fiddle with the targets, click recalculate and look at the effects on the charts before uploading. You can repeat this as much as you want without having to re-measure the room/system, so long as the room/system doesn't change in any way. Once uploaded the solution is in the processor's memory and can't be fiddled with, that is why you don't see the target cutoffs in the AVM/D GUI. If you change the solution on your PC you must re-upload to hear it.

Sorry to hear that.

Just for the record, I have not gone past v3.09c and not having any issues. I don't see any real need to go to 3.09f. Very happy biggrin.gif

Are the older firmwares available for download anywhere? If things don't work out with my issues with 3.09 I will want to roll back to 2.10 which I used earlier.

I'm planning on getting a new OPPO 103. I've read a lot of positive reviews of its video upconverting capabilities. Right now, everything runs through my D2V with the D2V sending the video to the tv. Has anyone compared the picture produced by the 103 to the one by the D2v? Although the picture produced by the D2v is stellar, I'm wondering if the OPPO will be better?
post #39070 of 42678
^ best scenario would be to use both. Oppo supports DVD 24p upconversion which Anthem does not, so enable that and always feed 1080p24 to the Anthem. If you are not into video calibration you can have the Anthem VXP pass the signal directly to your TV unchanged simply by not messing with any video processor settings. If you are going to calibrate the display you can take advantage of the custom gamma curves in the Anthem VXP (using Anthem's LiveVideoSettingsEditor software for the PC). Search my posts for LVSE if interested in what it can do.

I don't think so. I have saved some of the previous firmware installers for the 50v but not the D2v. If someone wants to set up an FTP server I can upload them.

Question about ARC after it has been uploaded with ARC Result.

Can someone please list the changes that can be made after the result has been uploaded, that will not hurt the uploaded result? ie. volume on subs, phase, ect?

Or even in D2 menus??Thanks

On a D2 not D2v, how would you set-up the OPPO? Would you still use 1080p 24, I dont belive you can bypass the video in D2?

I don't think you can touch any of that without hurting the ARC result. Sometimes we apply volume trims using the Anthem remote to work around decoding errors (i.e. with the older firmware the center channel was too loud with DTS-HD) or temporarily adjust certain speakers to taste on certain material but we generally leave it alone. I certainly would not adjust the subwoofer controls directly or physically move any speakers.

For video I believe it would be the same setup as D2v. I wasn't suggesting using the bypass mode of D2v3D, although you could, because the Anthem VXP really doesn't add any artifacts (except for the handy OSD).
post #39076 of 42678
So I would set the OPPO to 1080p 24 for all sources or just for bluray?? Then do I need a seperate input and video configuration? Thanks for the help. This is a great forumn!
post #39077 of 42678
There is an option for DVD 24p in the Oppo which I always leave on because I watch mostly film-based material. If you encounter problematic video material you may have to turn it off, I'm not sure if the Oppo will automatically fall back to 60 Hz (I am using a very old model). The Anthem will not, so when switching to a 60 Hz source, yes you need a separate video config.

This is what I have understood from Oppo and Anthem:

Keep 108024p ON in Oppo, and only bluray have 24p frame rate.

I have one configuration is Anthem with 1080p24 and I use that when watching Bluray.

I have another configuration in Anthem for everything other than bluray, and that is at 1080p60.

While 1080p24 ON in Oppo, it does not matter (or function) if you are just watching a DVD, but use the configuration with p60 in D2v.

Another safer approach could be to keep 1080p24 on AUTO instead of ON in Oppo, but that takes little more HDMI handshaking.

I am sure there are lot of other people on this forum with lot more knowledge on this than what I just said and they can explain further. I would like to confirm my approach as well.

Hi, Why does the measured ARC red line only go to 5K, I thought I had seen results that showed measured up to 20K in previous posts

The default, for the Max High Frequency, is 5 kHz. If you want to see what it looks like up to 20 kHz, then you will have to click on Target, change Max Frequency from 5000 to how high you want it to go, click OK, and then click on Calculate. Anthem recommends not going above 5 kHz because the mic is not accurate in the higher frequencies and the sound becomes directional. However, you are always free to experiment to see how it works out for your setup. You never know; you just might like the higher frequency setting.

Ninja,

Thank you, but I want to see the tweeters and make sure they are functioning correctly, due to reading prior posts. I do not want to apply above 5K without some serious consideration. Really just want to make sure tweets are OK!

Screen capture and post your charts so we can see what you are seeing. The red Measured curve should show up through 20KHz regardless of your Targets settings. What is likely happening is that the green Calculated curve is on top of it (since by default no correction is applied above 5KHz), and obscuring it.

To check that, go into Targets window, change anything then change it back to what it was, then accept that "change" (which will dismiss the Targets window). That will erase the green Calculated curves (since you need to do a new Calculate pass after any Targets changes) and so you should now see the red Measured curve without the green Calculated curve confusing you up there. To get the green Calculated curves back, click on the Calculate button in the strip top left.

Best way or one way to do that is to download and use a free program called REW.so you can chart the full frequency response of your system
You will need some extra equipment such as a microphone with good high frequency response and a microphone amp.
Check the REW forum for an equipment list or I can supply a list of what I am using.
post #39084 of 42678


Hi Bob,

I did as you suggested and it worked like a charm!

Here are the charts, to make sure my tweets are in good shape!

Also I will rerun arc with some new subwofer locations, once I get

feedback on tweeters!

Thanks Stewman,

I would like to see what you guys think of my measured arc response before looking at other systems, but it sounds like a great alternative!

I'm a bit overwhelmmed with the things I have going on now! LOL I been at this for a few months.
post #39086 of 42678
Well here are the new ARC charts with these changes.

I moved the Front Left and Right more forwrad and into the room by about 6-7 inches,

and I moved the subs into the left front corner and right rear corner. Like to get some feeback

against my last (BEST) postion which was the midpoint of front wall and midpoint of Left Wall length.

Thanks!

First Post is New, Next post is the Last position!
post #39087 of 42678


These are the last position of the subs and fronts. Subs were at the md points of front and left wall length.

My On Screen Display has suddenly stopped working.

I have an AVM40 so I don't have the fancy display anyway, but the setup display no longer works. I'm using the HDMI out.

The prepro transmits actual content just fine, just not it's own internal signal.

I've tried a factory reset and unplugging for 30 minutes with no joy. I tried to reinstall the firmware, but the AVM40 has decided it doesn't want a bar of that any more as well.

Anything obvious I may have missed?

AVfile,

You said that the "older firmware the center channel was too loud with DTS-HD". I installd the the latest version of the ARC softeare and have a D2 not D2v. I play piano and had a drummer over last night who was interested in hearing his Rush Snakes and Arrows on the big screen. We both agreed that the center channel sounded way to loud, (BTW it is a DTS MA) and I trimmed it approx 2-2.5 db to just get it in the ballpark.

I would also add that so far the guitars and treble sounds very loud and the bass drum and drums sound too low. The charts for this run are the first set above with the subs in corners. Although, I didn't notice the bass too low on some Diana Krall SACD I played earlier.

Can you tell me what you know about this known prob, and can it be fixed in the D2??or otherwise how do you get the system in trim for many different types of material? ie. DTS-MA, Doldy True, SACD, DVD-A ect?

The D2 does not decode DTS -HD so it is not a problem. To hear the DTS-HD track the player must decode to LPCM and send that to the D2. There was never a problem with the LPCM stream. The problem has been fixed in the latest firmware for the D2v
