    Crown itechHD’s require a specific number of coefficients. The last we checked, it was 897, but it might have changed. You may need to try different files with different numbers of coefficients until it works.If you still can’t get it to work, I suggest contacting Crown. They may have a problem with the FIR loading.

    Regarding precision, your 2nd screenshot shows that the coefficients do match. It’s just that the iTech display is rounding/truncating at 6 decimal places, which equates to approximate -120 dB relative to full scale; so I think you’ll find the trunction doesn’t matter.
