Smaart Setup Problem with SQ Interface

Hey Guys,
I’m currently configuring my smaart with the SQ audio interface. I’m done with routing and stuff, but for some reason the reference pink noise lacks all of the low-end. It gets send from Smaart to an output of the sq, from there it gets plugged into an local input and send back to Smaart via TieLine.
If I do this with a Sine Wave, the SQ receives every frequency with the same amount of gain, but u can see in Smaart RTA how low frequencies just get quite and quieter.
I really can’t find the issue, checked the same setup with a focusrite Scarlett and there it was working perfectly fine.

Is this one of the interface bugs the sq comes with? I just experienced digital artifacts so far when using it…
Im attaching a picture so u guys can see what I mean.

Any help or ideas appreciated!

Thanks in advance
Marian

Upload error, here is the picture.

Definitely not a bug, looks like you’ve either got a HPF or low shelf enabled somewhere in your chain.

I often use the interface section of my SQ and never an issue, I’d start up a blank scene and try this again, there must be something going on in your configuration.
