hi Guys
See attached screen with 4 REW measurements of my system with SHD Studio at Dirac switched off (no Dirac icon on the display). I was really puzzled to see the measurements change a lot when I switch between the four presets. Then I checked the SHD Studio app configuration, only to find out all other settings were left the signal path intact. I have noticed however, that input section shows 3-5ms delay and 0.4dB damping for the right channel (Dirac 2). 

Any idea what that is? Am I missing something? Is my unit broken? Is the Dirac Off button just doing half of the job? I got my unit repaired (display replaced) - could it got broken at the repair?


 

I managed to doge this issue by defining one profile with filter curtains swept to the left completely, so above 20Hz I get exactly the same response as with SHD Studio fully bypassed. But I'm still puzzled - am I doing something wrong, or MiniDSP crew crewed a few lines of code?

Could anyone from MiniDSP comment? Is it expected behaviour or mulfunction?

I have a similar problem, but I am not sure where the issue is. Is it the umik-1, the SHD Studio or my speakers and subwoofer? Both, speakers and subwoofer have a big frequency bump and hole at IIRC 26Hz and 32Hz or something, measured nearfield (5cm from the membrane). All filters in the speakers are disabled, no filters are set in the SHD Eq and dirac is turned off. Maybe I can attach a curve screenshot the next days. The result is the same with REW on Mac and windows.

I've posted a request to support on this one. To me it looks like a nasty bug, because when I use curtains, I get similar profile to the one when unit is switched off. I'm curious what SHD guys will respond. 

I got reply from support. Apparently it is as it should be. and to have reference point you can create an empty preset, which I don't know yet how to do

"Dirac Live time alignment and gain are always enabled once done so you can easily toggle bypass on Dirac and not have to worry about a large level change that could have happened in Dirac live. If you want to remove all delays, simply create a preset without any Dirac live inside. You can then toggle to that preset and you'll be sure to have zero gain/time alignment."

If you have a preset already with Dirac and you just want to remove gain and delays, can’t you reopen the project, disable delay/gain and resave the curve to the same preset?

In the SHD manual in chapter „8.5.5 Restoring to defaults“ on page 71 it is described how to reset the presets. Unfortunately it is only possible to reset the dirac filters, too, if resetting all 4 presets, not only the currently selected one. 

In the latest version of Dirac Live you can choose whether to apply the time delay and gain corrections or not. To clear previously saved Dirac time delays and gains the easiest way is therefore to disable these corrections in DL and then export a new filter to the SHD channel(s).

Before the software change I achieved the same with a measurement leading to not corrections but it's easier now. I'd prefer turning Dirac Live off switched this off too though.
