Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide - Page 1240

I get both issues too. However the volume has never been stuck low. I could always turn it up but it would be 20dB too low, which is my muting level. Is your muting level more than that?

I'll post the graphs later for more input.

I'll tell you what, I did not expect such a drastic level of audio improvement from the 50v vs the 50. Very happy with my upgrade. Got a pretty good deal on a 4 month old unit on Audiogon.

Yes, please post your Targets' View. It sounds like you might be having some speaker placement issues. The S8's are very good speakers, and they can go pretty low.

Are you bi-wiring them? If so check your connections.
And please post all your charts.

AVM 50 (no ARC) - single DSP
AVM 50/ARC - dual DSP
AVM 50v - dual dual-core DSP (like 4 single-core)

All different but in the latter two ARC result is the same. Twice the sampling rate requires twice the processing and for that matter twice the storage on the media. Number of DSPs doesn't mean anything on its own because if one DSP can do the job just as well as ten different ones, there's no point in using ten DSPs. The job that needs to be done determines which DSP to use and how many, and all that really matters is what comes out the output jack, not so much how it got there.

I'm primarily interested in playing my movies off ripped files on my hard drive and not directly from the PC's Bluray player. I want to use Windows Media Center or Apple TV3 as my main interface(s) to queue up everything and run the movies.

I have some spare parts (old 4870 radeon but no HDMI out just DVI and an Intel E8500/3.1Ghz Core 2 Duo CPU) but I'm not sure they will cut it for what I am looking to do. Particularly, the video card which does not have and HDMI out. Any thoughts/comments/help would be appreciated.

Also, does streaming movies from a native hard drive on your mobo work better/faster than having a USB drive attached to it?

Placement is very important to speaker response.
I looked at your pictures of your HT and it looks like the mains are in recessed alcoves which may be causing the problem you are experiencing.

In ARC, under 'tools' there is a very useful option called 'quick measure'. If you are not familiar with it, it allows you to run sweeps on one speaker at a time. It has been very helpful to many of us here in finding an optimal subwoofer position, but in your case it should help you find a better spot for your fronts.

Start it with LF and see what it looks like. Since you haven't posted your charts I can't be sure, but I guess there's a pretty big dip thats causing ARC to set its crossover so high.
Move it out a little from the wall and see what happens in QM. Keep moving it around until you get the best response possible.
Switch the QM to RF and repeat the process. Chances are its optimal position will mirror the RF.
If you have any other speakers that need their position tweeked (especially the sub) you can do that also while running QM.
Once their distance from your back and side walls is determined you may want to tweek the toe in of your fronts for optimal imaging (after you've run QM, but before re-running ARC.) Be sure that 'room eq' is turned off for the source you use to test your imaging.

You will of course need to re-run ARC after moving the speakers, but you should get a much better solution for your speakers.

This takes a little time, but will be well worth it in sound quality.

I redid ARC last night and it crossed over at 60hz. I had tightened the binding posts and re-positioned a bit. The LF and RF on my graphs are fairly the same. I'll get them posted shortly.

Now, I just have to understand Room Gain better. I'm really not that dense but I've read a bunch of posts here explaining it but for the life of me I do not understand why room gain is "good" and how tweaking it effects the ARC calculations. My room gain is at the max 3.9xxx. I am tweaking it down to and comparing the post calculation graphs and the calculated line looks to be much closer to the target line along the graphs with the gain tweaked down.

Again. Will get them posted. Their on another computer.

It's one of the reasons other correction schemes don't sound as good.

Movie mixers assume a modest amount of Room Gain will be present in your room -- 2-4 dB.

Room Gain is a room response characteristic. But unlike most of those, it is one ARC tries to measure and preserve. That makes recordings sound "natural" in your particular room. I.E., like "real" sounds that might happen in the room.

Room Gain is a shallow boost of bass frequencies. It shows on the charts as the shallow hump up of the Target curves near the crossover frequencies. The Room Gain value is simply the height of that hump in dB over the basic volume level of the solution (easily found in the flat part of the Target curves for the main speakers off to the right of the crossover frequencies).

Raise or lower the Room Gain value and you'll see how the shape of that hump varies. 0 dB Room Gain means no hump!

The audible effect of Room Gain is precisely what you might expect given the shape of that hump.

i have attached to messuement off my centerspeaker. One freestanding behind the screenwall (the first graph) and one at the same location, but with a small baffle mounted around the center speaker - the size off the baffle is about 1 feed from the speakerbaffle and out.
as you can see, it makes a big difference. i am exieded to see what happens when the bafflewall become mutch larger - the same size as the screen.... 108"

my acoustoc said that with the small room i got, there will always bee nulls and peaks.

edit. my speakers are closed, so there will not bee mutch output under 100hz - M&K mp2510 active studie monitors
