Topic: Digi 96/8 poor low frequency response

Hi,

sometimes I use my Digi 96/8 (Windows XP) for audio measurements. Some days ago I measured the FR of the card (output to input, ARTA Software) and found a drop of -1dB from 100 Hz to 20 Hz. Is this a hardware defect? FR should be flat from 20 to 20.000 Hz (-0.1 dB) according to the specs. Any help would be appreciated.
