interesting - at a glance it appears that Avid has changed their A/Ds and it's not for the better (at least in terms of filter ring). This should probably be in a separate thread - it's also difficult to see exactly what's going on from the low-res screenshots; higher res pictures would help.

If I switch to 96000, the signal remains almost unchanged!
I tried to do these manipulations with I / O 192 and this interface produces almost ideal rectangle shapes at any sampling frequencies. If from the output of Avid 16x16 analog to apply to the input of 192 I / O then the result is also excellent. If on the contrary, the result is depressing, which indicates the problems of the input channels at 16x16. the same problem with Avid Omni. I'm curious about this on all new avid interfaces?
Love to see your pictures but they are too tiny to be useful to see what has been done. Also, for conformity, vs using the signal generator plugin, I suggest using an audio file (even if that audio file is created by the signal generator.)

If anyone was wondering:
The Avid I/O output impedance of +4 is 50 Ohms
The MTRX output impedance is <30 Ohms
