The interface got paired with my Presonus Eris E5, no problems, the E5's have been set to unity (half their volume) and the Behringer takes care of the rest.

Don't get me wrong, it's not something you must have, but it was a very good and useful thing to have and the Behringer software is kinda of poor gut it does the job (and when it doesn't do it, you can always set a few things from within the DAWs). One thing I am already missing is the Control/Mixing Panel of the Focusrite. That's the only thing I downloaded from the Behringer site, by the way, I don't need anything else. No problems with the Win10 drivers (built 1909) which is always a good thing. It looks sturdy enough, the manual contains only the basic information but apart from the routins, it is a simple device. I read a ton of revivews and although I had never bought any Behringer device worth of 15 euros or more, I pulled the trigger and bought one. These two groups of connections have different specs (impedence) so I didn't want to mess around and waist time with any of this. So, I would have to connect 2 channels to the preamps and 2 channels to the line ins. I was just about to pull the trigger and buy the Scarlette 4i4 3st gen which costs more or less double the money, until I noticed that not only it had only two line ins (at the back) but since the 1st generation they removed 2 of the front preamps. Mind that I used to have a Scarlette 4i4 1st generation which I never had any issues but I sold it long time ago. So, I wanted a 4 input USB interface that could record at 48Khz/24bit 4 tracks at the same time without issues in order for me to digitize my master tapes from my 4 channel analoge track recorder.
