Yesterday I was testing gear at home and I noticed something when I went to calibrate FuzzMeasure. My Digi192 has terrible highend response.
So being the naturally curious person I am, I wondered does this change with the sample rate (assuming higher would be better of course) and behold it did change, unfortunately for the worse. As I go up in sample rates my 192 gets worse. To me this rules out that there is an issue in my analog domain (ie patchbay and cables) since it is sample rate dependent.
To make sure it's not just a core audio thing I repeated the test (more crudely, using signal generator and PAZ-meter) and observed the exact same behavior inside Pro Tools.
Went to my other studio tonight and did the same test and it was flat from 20-20,000 like it's supposed to. The 192s between home and the studio are about the same age, I use HD|Native at home and HD3 at the studio.
I assume this is something malfunctioning in my 192, right?
Has anyone else experienced this?
I attached the sweeps showing the issue, the best one is 44.1 and the worst is 96.
