Needed something which I can record my own songs with guitar accompaniment. Had a first interface with two inputs and without any control. Was total rubbish. This part here, however, is beautiful. Behringer was always used for good quality, that something has changed, but not on this machine. Of course something rustles in the background, but you can reduce acrobatics with a bit controller and software. And the same in advance: If you connect an electric guitar directly, then it there on the PC, a delay until the sound reproduced / is taken. That's not the mixer! That's Some software Affentheater with rights, etc., details there in Google. Experiment at easy with other recording software, the delay should disappear.
