Problem with transformed from Linkwitz with 2X4HD to DDRC24 7 months 1 week ago #58582

Hello
, I have a Minidsp 2X4HD updated to DDRC24 with Dirac and I have a problem to apply a Linkwitz transform for my Subwoofer.

When I enter the calculation result of the biquad of the spreadsheet in the plug in of the minidsp (filter to Advanced mode and enter the five parameters a1, a2, b0, b1, and b2) and apply to the Process button, I get NaN error and the curve disappears.

Is this a bug? or else would I have made a mistake?

I put you the screenshots below.

Thank you Tiptoe

I believe the update to DDRC-24 status drops the internal sample rate from 96 kHz to 48 kHz. My guess is your issue may be a result of this.

Edit: should have looks at your photos! Looks like you've factored in the 48 kHz sample rate going by the last one.

Thank you for helping me

Haven't you got another idea why this isn't working? 

Are you sure that it should not work in 96khz?

​​​Do we have to write the a1, a2, b0, b1, b2 in a precise way? or others?

Thank

Yes, your biquad format is wrong. See the manual for correct, or follow the template already there in the entry box.

Thank you
There was a comma problem at the end of each line (a1, a2 etc.) And also a problem with the spreadsheet which put commas instead of dot at the beginning.
Now i have succeeded
 Thank you
