Topic: AI4S AIO High Frequency noise while running on 192khz
So recently I got an AI4S/192 AIO to get some more inputs for my trusty old HDSP 9632 (also have an AO4S/192 AIO and an ADI-2 Pro FS R over optical SPDIF hooked up to it). Now when running the system on 192khz the new AI4S shows high frequency noise at -50db from around 45khz up (see screenshot attached) regardless of whether anything is plugged in or not, clock source or other settings.
I usually record and monitor at 96k so I never noticed it before, but today I switched to the ADI as clock source and tried different sample rates and filter settings on it, and as soon as the system runs higher than 96 the AI4S' noise becomes obvious in Digicheck and Totalmix. Any idea what could cause it?
