16Rig - Phase Inversion for line inputs?

I’ve got an AF 16Rig, and a Push 3 Standalone.

I have Output 1 and 2 of the Push 3 connect to inputs 7 and 8 on the 16Rig using 1/4" TRS cables, and then I linked those inputs in AFCC (7 hard panned left, 8 hard panned right).

I then have Input 7-8 as a mixer strip in the main mix.

While playing the Push 3, I noticed there was a lack of bass, and it sounded phase-y. If I load the same project in Live on my Mac, it sounds great.

I took me a while, but eventually I found that enabling the phase inversion button in AFCC made it sound “normal” again.

But I would like to know… why? What would be a cause of improper phase matching for a line-in device like the Push 3 Standalone?

Hi Ryan,

Could you please record in Ableton the signal received in 16Rig 7-8 ins from the Push, with no phase inversion engaged ans share a screenshot of the stereo waveform here?

Also, do you have another audio interface to plug the Push in, and compare versus the 16Rig?
If no, you could try with another 16Rig inputs pair

Cheers,
