Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide - Page 517

So I am comparing MC SACD from an Esoteric DV-50 Analog Direct to the D2 vs. Oppo 980 DSD/PCM conversion to 88.2/24 to the D2 with ARC enabled. And my family is out of town until tomorrow afternoon. I think audiophiles live for these weekends

Still do 5 measurements? Would you still spread 5 out laterally like you have previously mentioned? Or maybe one in front and behind the sweet spot?

Logically, since I am the main user of the D2, and I sit in the same seat, the ARC would work best if I cluster the 5 mic positions around my sitting position. It didn't work! The ARC works much better to tame the room and blend the sub with the speakers if you make your mic positions at least 2' apart. Start at your prime listening position, then 2 feet or more to one side, then 2'+ to the other side, then 2'+ outside the second position, then 2'+outside the third. For example:
#5---#3---#1---#2---#4

Or #5--- #1--- #5
#3--- #2---
Make sure that the mic is pointing straight towards the cieling, and that the mic height is the same. The mic can be moved forward or back in the room, but the #1 reading needs to be at the main listening position, the mic must be pointed straight up, the mic height should be constant, and the mic needs to be atleast 2 feet apart.
Its tempting to put all 5 positions close to the #1, but ARC works better if you allow atleast 2' between them.

I then use it to try tweaking the calculations. ie., I open up the file, try playing with the various targets by pressing the "targets" tab, and then press the "calculate" tab. If the results look good, I'll do a "save as" to not overwrite the initial default calculated file. If you want to try one of the files containing the resulting curves you've obtained, plug in your pre/pro and press the "upload" tab while you are in the file you want to load. Read only or write protect can be done by right clicking on the file and it will be under "properties", so you don't mistakenly overwrite your initial setting or any other ones you wish to protect.

Hope this helps.

Here are my ARC graphs. What do you think?
My ARC Crossovers are; Room Gain 2.199834(Movie) 2.123138(Music)
L/R Front...40 L/R Surround...65 Center..50 Sub...105,(Movie)
Same crossovers for music minus the center channel which I did not use.

I am going to try my 2nd option with the sub slipped in between the front left and center.

For instance, prior to ARC, I thought some movies had very deep bass and now with ARC, some of these loud scenes have settled down but others that were anemic are now very good. A review from me 4 weeks ago would not be accurate and so it may be for many reviewer. Just a thought as I read reviews of Transformers in Blu-ray with TrueHD vs. HD DVD with DD+.

I have compared component 480i and HDMI 1080i and 1080p from the 983 to the D2 and they all look the same.

I'm sure how ARC will deal with my (6) LFE channels
will still be a MYSTERY. It certainly does not expect
that.

I have to say that I am very pleased with how ARC sounds in my system. Sound quality definitely improved, most noticeably with tighter bass, and a more articulate and more defined sound to all audio. A very worthwhile upgrade!

Any comments on my measurements?

With the output matching now, it's hard to put my finger on it, but the sensation isn't quite as good as it was before ARC....seems to be more easy to locate in the chair and slightly delayed. Any thoughgts?? I wonder if there would be a way to get an non-ARC'd sub output from one of the two sub outputs??

Do you have an acoustically treated room? It looks like ARC found somewhat less inherent Room Gain in your room than many of the charts we have seen here (the "hump" in the Target and Calculated curves near the crossover). This is not a problem -- I'm just curious about what might be the cause.

Your subwoofer looks like it is probably rated down to 30Hz or 26Hz, which is also fine, but not quite as deep as some of the servo-assisted subs people have been reporting here. Again, I wouldn't worry about that, you are only down a little at 20Hz. You won't make the floor bounce like DRHANKZ does with his "low rider" style floor thumpers, but you ALSO won't have to deal with problems in some movies that have excess sub-sonic energy in the LFE that they simply forgot to filter out!

Your room (or speakers) look like they might be a little "bright" around 10KHz, so if you want to experiment with a 12KHz target that could be fun. Unlike most of the curves we've seen here your Measurements are actually a little hot out there in the front speakers. It will be interesting to see if you hear a difference though since your residuals out there are not large.

You've got a pretty sizable room mode at 40Hz that ARC is pulling back into line. The result may be that your initial impression is that explosions sound a little thin at first since they tend to run between 30 and 50Hz (see your sub and LF/RF Measured curves). But your bass should sound quite a bit tighter across the board -- and much more natural. I suggest you take some time to get used to these results and I think you will like them a lot.
