Based on your picture above, I'm going to assume that you do not sit in between the sofa cushions ("REAL CENTER"), right? That would be odd but your choice, nonetheless. Can you move the couch to the left so that seat position #1 is within the centerline of the TV?

if you can't and you actually sit in positions 1 or 2 (like I do), that's ok since the D2v accepts your speaker distance measurements relative to your MLP and adjusts the speaker trims and delays accordingly so that you always hear a center image wherever you are seated.

In reality, I do seat just directly in front of the middle of the TV/Center speaker where I pasted the camera icon, but it is not between the cushions as the sofa design has very big seats that fit almost 2 people each, just couldn't find a similar one for the mockup.

So just to clarify the numbers on the photo are "ARC positions for the mic" you recommended, while the camera is where I actually seat and my wife would seat in a couch position between "ARC 1" and "ARC 3"

Moving the couch to the left is not possible as it would block the door that you can see to the bottom left corner, it is as left as it gets so 1 is off-center to the right as in the picture above.

So with that explained, you still recommend those 5 positions for measurement and then introducing speaker distance measurements to the MLP (REAL CENTER, which is not the same position as the "1")? Or you recommend matching MLP with position 1 which will make the sound shift towards the "unused" area of the sofa?

Now that you've explained that you have wide seat cushions, then ARC position 1 should be directly where you sit, in front of the middle of the TV/Center speaker, by the camera icon.

The very first ARC microphone position is where the listener sits. Then, you can move 2 feet to the left and right of it for ARC positions 2 and 3. Positions 4 and 5 would not change as they are in between ARC positions 1 & 2 and 1 & 3, but placed in front of you.

Hope this makes sense...

hooked up new JVC to AMV-60 to OPPO 203 all running thru a (actually only 10 Y/O cable) cable. Tested with 4-K, then 4K HDR, and all ran perfectly! I remember that cable issues included drop-outs, Sparklies, or no pic at all. So, I assume that since I have none of those issues, a newest hi-speed, guaranteed super duper cable will not improve on the fantastic pic on my 123" Stewart 1.3 gain screen.
Only wish I could find the receipt for the cable so as to share. Sorry.
My only complaint is it takes the Anthem forever to recognize changing sources.( Sat to Blu Ray for instance)

But it is my understanding that I will not hear the same when seated at position 2 or 3 no matter how good ACR is, to get started due to distance to speakers, right?

So considering that, wouldn't I be hearing a worse performance from the speakers when I seat in my "Real Center" MLP (which is between positions 2 and 1 and just behind position 4) when compared to the "measured MLP" which is in the middle of the sofa and where ACR averaged the 5 measurements?

Or Should I measure it like the picture above, but then input the speaker distances to the "real center" MLP to ensure I get the full benefit of it?
It looks like your seat is up against the back wall, so you might want to try this pattern from the Persona ARC manual. It's the newest Paradigm/Anthem product with ARC.

Yeah, nice and impressive video but I still missed that ARC configuration you mentioned above in the video. That's ok though. No biggie!

I'm sure it's been asked..
I want to ARC for 1 main listening position..
What is the best ARC mic layout to use for just this one seat...

I heard. Maybe to use positions near where my ears will be, the width of my head...

Just want your thoughts...
Thanks

Definitely not. ARC has to be able to distinguish between the inherent output of the speakers and what the room is doing to that output, otherwise it can't do its job. And THAT means you have to have mic positions which are spaced out -- not clustered near one head position.

Put mic position #1 near your head position, as that's the one that is used for setting speaker levels.

Interesting...

And thanks...

See my photo..

With this layout, would it be best to cluster the mic readings on the love seat... The chairs are for over flow of guests.. ☺️

So love seat is the prime area...
Would you mabe take 5 readings over the width of love seat..

^ Put mic #1 at center seating. Pick the other 4 positions such that:

1) The mic positions span the listening area you want to correct -- both side to side and front to back,

2) Each subsequent mic position in sequence alternates from one side to the other of #1 ,

3) The mic positions are not all at the same distance from the screen -- for example have some set up near the back of the headrests and some at the front of the seats

4) No two mic positions -- whether or not sequential -- should be set up closer than 24 inches apart. I use 30 inches as my minimum.

5) The mic tip is not set closer than 18 inches from a blocking or reflecting surface like a wall or high seat back. If necessary raise the mic tip a bit to clear a seat back, or shift the mic position closer to the screen to get distance from a wall.

6) The mic tip should point straight up towards the ceiling. The mic tip should be set at seated ear height for all positions (adjusted as necessary for rule (5)).

The mic hears audio from the entire hemisphere -- 360 degrees around -- above the tip. So that's the area you want to keep clear of nearby things that block or reflect the sound.

Here's a pattern that should work for you:

(back wall)

.....2....1.....3....
4....................5

(screen)

Cool and thanks for great procedure..

Curious as to why they suggest in front or behind listening position...
I ask as you dont actually sit there and those spots might have big bass peaks or dips...

Thanks
