the first position measurement is vital .. the sweet spot one , the other 8 are clustered around the sweet spot so that a sort of generic correction can be applied that works if you move your head around , otherwise it becomes a very small spot thats corrected.
It depends on the nulls as to whether they will be attended to , a very steep crevasse cannot be dealt with as its a destructive null , the more shallow "valleys" can be dealt with , to an extent
The green line is the expected response , it is not the actual measured response after correction.. which can and does differ
I use 4 subs in addition to the DRC .. they distribute the bass and provide 4 extra bass sources , so they actually eq the bass almost by themselves all over the room due to interference
I dont cross over to my speakers but let them run full bore (they go to 20hz and below) .. dirac sees all the subs and speakers as a single entity.
As to TT .. get a pro 24/96 or higher AD converter..they are VERY good and then you can integrate your analog source with minimal losses
Hello to All,
I am new to this chat few days ago and found this thread interesting. I have been looking for something simple in room correction. I have just placed and order for DDRC 22D.
Perhaps someone can help with some of my questions:
1. It is rated at 24/96. How does this affect the source if it is at a higher rate, say 24/192?
2. Does this mean that Devialet will up convert to 24/192 after the DDRC box?
3. Where exactly does this unit fit in the chain, between PC and Devialet?
4. What is the issue with input/source selection that you will need and extra USB streamer($35) that Rodney has suggested?
May be these questions will become clearer once I dip my hands into this.
Thanks.
David
While not an expert on this topic, there are others who will chime in I am sure, If the output of the DDRC 22D is up to 24/96 then unless you have a device prior to the DDRC that can down convert 24/192 source files to 24/96, you are limited to 24/96 source material.
The Devialet will take the output from the DDRC as it is passed to it. ( Not delving into the topic of any up sampling the Devialet does internally ).
From reading the online material looks like you will need a streamer or PC/MAC prior to the DDRC to feed it the source material. Many of these devices will allow you to down convert material over the 24/96 rate supported by the DDRC.
So Streamer/PC to DDRC to Devialet.
What were you planning on using in front of the DDRC?
Thanks for the feedback. I am using MacMini>iTunes>>Devialet at the moment.
I understand that the down convert and up convert. Does it negate the sound quality if the file is 24/192 since it will be down convert to 24/96? Loss of SQ here?
I don't think the loss of sound quality will be significant especially since it is from 24/192 to 24/96. However I believe you may need to consider using software other than iTunes.
Or rather let me ask you this, do you have high resolution content already that you are happily playing through the iTunes to Devialet chain?
The majority of my content is ripped from CD at 16/44. I have begun to collect HD materials at 24/96 or 24/192.
Using iTunes most of the time but moving to ROON Lap slowly.
Ah well Roon I know very well. You can definitely configure Roon to down sample all content above 24/96. In fact I use it to down sample the DSD128 files I have as the Devialet only accepts up to DSD64.
So if you have any Roon related questions more than happy to assist. I have it running on a Mac Mini with all my music on my Synology NAS. Sorry I didn't notice your signature earlier....
And I wouldn't mind having a "Deviate 800".....
Thank you for clarification. I need to brush up on these digital 24/96 stuffs. So you mean to say you down sample it in ROON to 24/96 first? Why, may I ask? Is it to reduce a conversion process in the chain?
You have a great system already. When I moved from D400 to D800, there improvement is not as much as when I upgraded from D200 to D400. I would have been happy with just the D400 (in my system-qualified here).
I think I was less than clear. I meant on your case as the DDRC is limited to 24/96 you choose to have Roon ( if you were using it ) down sample any 24/192 content to 24/96 so it could be processed by your DDRC.
If you were going straight from Roon to the Deviled you would not need to downsample the 24/293 material. In my case I go from Mac Mini running Roon straight to Devialet do any 24/96 or 24/192 content is passed straight through with no down sampling.
My example was poor, what I intended to say is the only thing I have Roon down sample are the few files I have in DSD 128 format, as Roon can only handle DSD 64 format. As you have no DSD content this is something you need not worry about.

OK. I got it. I don't have any DSD files.
I was looking at ROON audio setting I didn't see any option of 24/96 except that of DSD.
Are you using the $35 dollar USB streamer option to alleviate the output default issues?
